Blockade of Germany (1939 - 1945)
Encyclopedia
The Blockade of Germany (1939–1945) also known as the Economic War, was carried out during the Second World War
World War II
World War II, or the Second World War , was a global conflict lasting from 1939 to 1945, involving most of the world's nations—including all of the great powers—eventually forming two opposing military alliances: the Allies and the Axis...

 by Great Britain, France and later the United States in order to restrict the supplies of minerals, metals, food and textiles Germany needed to sustain its war effort. While mainly consisting of a naval blockade, the economic war, which formed part of the wider Battle of the Atlantic also included the preclusive buying of war materials from neutral countries to prevent them going to the enemy, and the widespread use of strategic bombing.

There were four distinct phases. The first period was from the beginning of European hostilities in September 1939 to the end of the "Phoney War" during which the Allies

 and Axis powers both intercepted neutral merchant ships to seize deliveries en route to the enemy. The second period began after the rapid German occupation of the majority of the European landmass which gave them control of major centres of industry and agriculture. The third period was from late 1941 after the beginning of hostilities between America and Japan, and the final period came after the tide of war finally turned against Germany after heavy military defeats up to and after D-Day
D-Day

Britain considered naval blockade to be a completely legitimate method of war, having previously deployed the strategy in the early nineteenth century to prevent Napoleon's fleet from leaving its harbours to attempt an invasion of England—Napoleon had also blockaded Britain.

, many people began to believe that a new ‘Great War’ was coming, and from late 1937 onwards Sir Frederick Leigh-Ross, the British government's chief economics advisor, began to urge senior government figures to put thought into a plan to revive the blockade so that the Royal Navy – still the world’s most powerful navy – would be ready to begin stopping shipments to Germany immediately war was declared. Leigh-Ross had represented British interests abroad for many years, having embarked on a number of important overseas missions to countries including Italy, Germany, China and Russia, experience which gave him a very useful world wide political perspective.

Making use of tip-offs provided by a vast array of individuals such as bankers, merchant buyers, waterfront stevedores and ship operators doing their patriotic duty, the Navy could have priceless advance knowledge of which ships might be carrying contraband long before they reached port.

Initially the Prime Minister, Neville Chamberlain was not keen on the idea and still hoped to avoid war, but following his appeasement of Hitler at Munich in September 1938, which was widely seen as a stopgap measure to buy time, he too began to realise the need for urgent preparations for war. During the last 12 months of peace, Britain and France carried out a vigorous build up of their armed forces and weapons production. The long-awaited Spitfire fighter began to enter service, the first of the new naval vessels ordered under the 1936 emergency programme began to join the fleet, and the Air Ministry made the final touches to the Chain Home

A joint British–French staff paper on strategic policy issued in April 1939 recognised that, in the first phase of any war with Germany, economic warfare was likely to be the Allies only effective offensive weapon. The Royal Navy war plans, delivered to the fleet in January 1939 set out three critical elements of a future war at sea. The most fundamental consideration was the defence of trade in home waters and the Atlantic in order to maintain imports of the goods Britain needed for her own survival. Of secondary importance was the defence of trade in the Mediterranean and Indian Ocean. If Italy, as assumed also declared war and became an aggressive opponent, her dominating geographical position might force shipping to go the long way around the Cape of Good Hope

, noted that there were all kinds of shortages even before the war began. In contrast to Britain, where rationing came much later and was never as severe, such was the need for metal that park railings were already being taken away to be melted down for scrap, and Shirer found that there were no oranges in his hotel restaurant. On 10 August 1939 Nazi officials privately admitted to Shirer that, after the conquest of Poland, the other eastern Balkan states of Hungary, Romania and Yugoslavia also had to be occupied, after which Germany would be self-sufficient and no longer need fear the Allied blockade.

On 24 August 1939, a week before the invasion of Poland which started the war, Germany announced rationing of food, coal, textiles and soap, and Shirer noted that it was this action above all which made the German people wake up to the reality that war was imminent. They were allowed one bar of soap per month, and men had to make one tube of shaving foam last five months. Housewives soon spent hours standing in line for supplies; shopkeepers sometimes opened otherwise non-perishable goods such as tinned sardines in front of customers when they were bought to prevent hoarding. The clothing allowance was so meagre that for all practical purposes people had to make do with whatever clothing they already possessed until the war was over. Men were allowed one overcoat and two suits, four shirts and six pairs of socks, and had to prove that the old ones were worn out to get new. Some items shown on the coupons, such as bed sheets, blankets and table linen could in reality only be obtained on production of a special licence.

Although the Nazi leadership maintained that the Allied strategy of blockade was illegal, they nevertheless prepared to counter it by all means necessary. In an ominous foreshadowing of the unrestricted submarine warfare

As in WWI, a combined War Council was formed to agree strategy and policy, and just as the British Expeditionary Force, which was quickly mobilised and sent to France was placed under overall French authority, so various components of the French navy were placed under British Admiralty control.

In Britain it was widely believed that the bombing of big cities and massive civilian casualties would commence immediately after the declaration. In 1932 the MP

". This message sank deeply into the nation's subconsciousness, but when attacks did not come immediately, hundreds of thousands of evacuees gradually began to make their way home over the next few months.

Scapa Flow was again selected as the main British naval base because of its great distance from German airfields, however the defences built up during WW1 had fallen into disrepair. During an early visit to the base, Churchill was unimpressed with the levels of protection against air and submarine attack, and was astounded to see the flagship HMS Nelson putting to sea with no destroyer escort because there were none to spare. Efforts began to repair the peacetime neglect, but it was too late to prevent a U Boat creeping into the Flow during the night of 14 October and sinking the veteran battleship HMS Royal Oak with over 800 fatalities.

Although U boats were the main threat, there was also the threat posed by surface raiders to consider; the three ‘pocket battleships’ which Germany was allowed to build under the Versailles Treaty had been designed and built specifically with attacks on ocean commerce in mind. Their strong armour, 11 inch guns and 26 knots (51 km/h) speed enabled them to out-match any British cruiser, and two of them, the Graf Spee and the Deutschland had sailed between August 21 and 24th and were now loose on the high seas having evaded the Northern Patrol, the navy squadron that patrolled between Scotland and Iceland. The Deutschland remained off Greenland waiting for merchant vessels to attack, while the Graf Spee rapidly travelled south across the equator and soon began sinking British merchant ships in the southern Atlantic. Because the German fleet had insufficient capital ships to mount a traditional line of battle, the British and French were able to disperse their own fleets to form hunting groups to track down and sink German commerce raiders, but the hunt for the two raiders was to tie down no less than 23 important ships along with auxiliary craft and additional heavy ships to protect convoys.

At the start of the war a large proportion of the German merchant fleet was at sea, and around 30% sought shelter in neutral harbours where they could not be attacked, such as in Spain, Mexico, South America, America, Portuguese East Africa

Contraband control

The day after the declaration, the British Admiralty announced that all merchant vessels were now liable to examination by the naval Contraband Control Service and by the French Blockade Ministry, which put its ships under British command. Because of the terrible suffering and starvation caused by the original use of the strategy, a formal declaration of blockade was deliberately not made, but the communiqué

It included all kinds of foodstuffs, animal feed, forage, and clothing, and articles and materials used in their production. This was known as Conditional Contraband of War.

s constantly sending out cargo listings and manifests to be checked against import quota lists. Even for innocent ships, a delay of a day or two was inevitable; Contraband Control officers were under instructions to be extremely polite and apologetic to all concerned. Neutral captains often expressed utter astonishment and bemusement at the level of British advance knowledge of their activities, and soon realised it was hard to hide anything. Although numerous attempts were made to bypass the blockade, the net was extremely hard to avoid, and most neutral captains voluntarily stopped at one of the eight Allied Contraband Control ports.

The Ministry of Economic Warfare

The job of co-ordinating the various agencies involved in the blockade was carried out by the Ministry of Economic Warfare (MEW), which in the last few weeks before the outbreak of war had been set up by Frederick Leigh-Ross. Leigh-Ross had not been put off by Chamberlain
Neville Chamberlain
Arthur Neville Chamberlain FRS was a British Conservative politician who served as Prime Minister of the United Kingdom from May 1937 to May 1940. Chamberlain is best known for his appeasement foreign policy, and in particular for his signing of the Munich Agreement in 1938, conceding the...

's initially lukewarm reception to his plan to revive the blockade, but had in fact spent the time after Munich to continue his preparations regardless. Leigh-Ross recruited shrewd bankers, statisticians, economists and experts in international law and an army of over 400 administrative workers and civil servants for his new ministry. It was their job to compile and sift through the raw intelligence being received from the various overseas and other contacts, to cross-reference it with the known data on ship movements and cargoes and to pass on any relevant information to Contraband Control. They also put together the Statutory List – sometimes known as the 'blacklist' – of companies known to regularly trade with, or who were directly financed by, Germany. In mid-September the Ministry published a list of 278 pro-German persons and companies throughout the world with whom British merchants and shipowners were forbidden to do business, subject to heavy penalties. When shipments from these companies were detected they were usually made a priority for interception.

One lesson that was learnt from WW1 was that although the navy could stop ships on the open seas, little could be done about traders who acted as the middleman, importing materials the Nazis needed into their own neutral country then transporting it overland to Germany for a profit. Leigh–Ross spent the months before the war compiling a massive dossier on the annual quantities of materials the countries bordering Germany normally imported so that if they exceeded these levels in wartime, pressure could be brought on the authorities in those countries to take action. Diplomats from the Scandinavian nations, as well as Italy and the Balkan countries, who were also major suppliers to Germany, were given quota lists of various commodities and told they could import these amounts and no more, or action would be taken against them.

A ship stopping at a Control port raised a red and white flag with a blue border to signify that it was awaiting examination. At night the port authorities used signal lights to warn a skipper he must halt, and the flag had to stay raised until the ship was passed. Arrangements for boarding and examining ships were made in the port ‘Boarding Room’, and eventually a team of 2 officers and 6 men set out in a fishing drifter or motor launch to the ship. After apologising to the captain for the trouble, they inspected the ship’s papers, manifest and bills of lading. At the same time the wireless cabin was sealed so no signals could be sent out while the ship was in the controlled zone. After satisfying themselves that the cargo corresponded with the written records, the party returned ashore and a summary of the manifest, passengers, ports of origin and destination was sent by teleprinter to the Ministry. When the ministry’s consent was received, the ship's papers were returned to the captain along with a certificate of naval clearance and a number of special flags – one for each day – signifying that they had already been checked and could pass other patrols and ports without being stopped. If the Ministry found something suspicious, the team returned to examine the load. If part or all the cargo was found suspect the ship was directed to a more convenient port where the cargo was made a ward of the Prize Court

 by the Admiralty Marshall who held it until the Court sat to decide the outcome, which could include returning it to the captain or confirming its confiscation to be sold at a later time and the proceeds placed into a prize fund for distribution among the fleet after the war. A disgruntled captain could dispute the seizure as illegal, but the list of banned goods was intentionally made broad to include "any goods capable of being used for or converted to the manufacture of war materials".

 for explosive cellulose and newsprint. Germany began by targeting the Norwegian, Swedish and Finnish pulp boats, sinking several before Sweden shut down its pulp industry and threatened to stop sending Germany iron ore unless the attacks ceased. Germany then began seizing Danish ships carrying butter, eggs and bacon to Britain, in breach of a promise to allow Denmark to trade freely with her enemies.

Up to 21 September 1939 over 300 British and 1,225 neutral ships had been detained, with 66 of them having cargo confiscated. In many cases these cargoes proved useful for the Allies' own war effort – Contraband Control also intercepted a consignment of 2 tons of coffee destined for Germany, where the population had long been reduced to drinking ersatz substitutes. When the manifest of the Danish ship Danmark, operated by the Halal Shipping Company Ltd, was inspected, the recipient was listed as none other than Herr Hitler, President Republique Grand Allemagne! In the first 6 weeks of the war the average number ships stopping at Weymouth was 20, and while many were allowed to continue after a brief examination of the ships papers, out of 74 carrying 513,000 tons, 99,300 tons of contraband iron ore, wheat, fuel oil, petrol and manganese

 were seized.

The shipping shortage

At the beginning of the war, Germany possessed 60 U-boats, but was building new vessels quickly and would have over 140 by the summer of 1940. While Britain could call on impressive flotillas of battleships and cruisers for direct ship to ship confrontations, these heavy vessels were of limited use against U Boats. Britain now retained less than half the total of 339 destroyers she had at the height of the battle in 1917 when the U Boats almost forced Britain to consider surrender.

Orders were immediately placed for 58 of a new type of small escort vessel called the Corvette

 was laid down. To free up destroyers for ocean going and actual combat operations, merchant ships were converted and armed for escort work, while French ships were also fitted with ASDIC sets which enabled them to detect the presence of a submerged U Boat.

The massive expansion of ship building stretched British shipbuilding capacity - including its Canadian yards - to the limit. The building or completion of ships that would not be finished until after 1940 was scaled back or suspended in favour or ships that could be completed quickly, while the commissioning into the fleet of a series of four new aircraft carriers of the Illustrious class

To bridge the gap during the first crucial weeks while the auxiliary anti-submarine craft were prepared, aircraft carriers were used to escort the numerous unprotected craft approaching British shores. However this strategy proved costly; the new carrier HMS Ark Royal

 to remain resolutely neutral in the conflict.

In the first week of the war, Britain lost 65,000 tons of shipping; in the second week, 46,000 tons were lost, and in the third week 21,000 tons.
By the end of September 1939, regular ocean convoys were in operation, outward from the Thames and Liverpool, and inwards from Gibraltar, Freetown and Halifax. To make up the losses of merchant vessels and to allow for increased imports of war goods, negotiations began with neutral countries such as Norway and Holland towards taking over their freighters on central government charter.

The Navicert

Elsewhere, the blockade began to do its work. From Norway, across and down the North Sea, in the Channel and throughout the Mediterranean and Red Sea, Allied sea and air power began slowly to bleed away Germany’s supplies. In the first 7 days of October alone, the British Contraband Control detained, either by confiscating neutral cargoes or capturing German ships, 13,800 tons of petrol, 2,500 tons of sulphur, 1,500 tons of jute (the raw material from which hessian and burlap cloth is made), 400 tons of textiles, 1,500 tons animal feed, 1,300 tons oils and fats, 1,200 tons of foodstuffs, 600 tons oilseeds, 570 tons copper, 430 tons of other ores and metals, 500 tons of phosphates, 320 tons of timber and various other quantities of chemicals, cotton, wool, hides and skins, rubber, silk, gums and resins, tanning material and ore crushing machinery.

Two months into the war, the Ministry reintroduced the 'Navicert' (Navigational Certificate), first used to great effect during WW1. This system was in essence a commercial passport applied to goods before they were shipped, and was used on a wide scale. Possession of a Navicert proved that a consignment had already been passed as non-contraband by His Majesty's Ambassador in the country of origin and allowed the captain to pass Contraband Control patrols and ports without being stopped, sparing the navy and the Ministry the trouble of tracking the shipment. Violators, however, could expect harsh treatment. They could be threatened with Bunker Control measures, refused further certification or have their cargo or their vessel impounded. Conversely, neutrals who went out of their way to co-operate with the measures could expect 'favoured nation' status, and have their ships given priority for approval. Italy, though an ally of Hitler, had not yet joined the war, and its captains enjoyed much faster turnarounds by following the Navicert system than the Americans, who largely refused to accept its legitimacy.

U.S. reaction to the British blockade

Passenger ships were also subject to Contraband Control because they carried luggage and small cargo items such as postal mail and parcels, and the Americans were particularly furious at the British insistence on opening all mail destined for Germany. By 25 November 1939, 62 U.S. ships of various types had been stopped, some for as long as three weeks, and a lot of behind-the-scenes diplomacy took place to smooth over the political fallout. On 22 December the US State Department made a formal protest, to no avail. On 30 December the Manhattan, carrying 400 tons of small cargo, sailed from New York to deliver mail to Italy, but was stopped six days later by a British destroyer at Gibraltar. Although the captain went ashore to make a furious protest to the authorities and the US consul, the ship was delayed for 40 hours as British Contraband Control checked the records and ship's manifest, eventually removing 235 bags of mail addressed to Germany.

In the U.S., with its tradition that "the mail must always get through", and where armed robbery of the mail carried a mandatory 25 year jail term, there were calls for mail to be carried on warships, but nevertheless the exercise – as with all such journeys – was repeated on the homeward leg as Contraband Control searched the ship again for anything of value that might have been taken out of Germany. On 22 January the UK ambassador was handed a note from the State Department calling the practice 'wholly unwarrantable' and demanding immediate correction. But despite the British Foreign Office urging the Ministry of Economic Warfare to be cautious for fear of damaging relations with the US, the British claimed to have uncovered a nationwide US conspiracy to send clothing, jewels, securities, cash, foodstuffs, chocolate, coffee and soap to Germany through the post, and there was no climbdown.

'Gruss und Kuss'

From the war's beginning, a steady stream of packages, many marked Gruss und Kuss (Greetings and Kisses) had been sent from the United States through neutral countries to Germany by a number of US-based organisations, euphemistically termed 'travel agencies', advertising special combinations of gift packages in German-language newspapers. Despite high prices, one mail company, the Fortra Corporation of Manhattan admitted it had sent 30,000 food packages to Germany in less than three months, a business which exceeded US$1 million per year. The British said that, of 25,000 packages examined in three months, 17,000 contained contraband of food items as well as cash in all manner of foreign currency, diamonds, pearls, and maps of "potential military value."

, the American government banned outright the sending of parcels through the US airmail. During this period, the Italian Lati Airline, flying between South America and Europe was also used to smuggle small articles such as diamonds and platinum, in some cases, concealed within the airframe, until the practice was ended by the Brazilian and US governments. The US travel agencies were eventually closed down along with the German consulates and information centres on 16 June 1941.

The phoney war

During the early months of the war—the phoney war—the only place where there was any real fighting was at sea. News of the successes achieved by the men of Contraband Control were rarely out of the newspapers, and provided useful propaganda to shore up civilian morale. In the first 15 weeks of the war the Allies claimed to have taken 870,000 tons of goods, equal to 10% of Germany's normal imports for an entire year. This included 28 million USgals (105,991.5 m³) of petrol and enough animal hides for 5 million pairs of boots, and did not take account of the loss to Germany from goods that had not been shipped at all for fear of seizure.

German preparations to counter the effects of the military and economic war were much more severe than in Britain. On 4 September a tax of 50% was placed on beer and tobacco, and income tax went up to 50%. For months previously, all able-bodied people in cities had by law to carry out war work such as filling sandbags for defenses and air-raid shelters, and it was now made an offense to ask for a raise in salary or to demand extra pay for overtime. On 7 September wide-ranging new powers were granted to Heinrich Himmler

 to punish the populace for 'Endangering the defensive power of the German people'; the next day a worker was shot for refusing to take part in defensive work. The new legislation, frequently enforced by the Peoples Court, was made deliberately vague to cover a variety of situations, and could be very severe. In time it would lead to the death penalty for such crimes as forging food coupons and protesting against the administration. Shirer recorded in his diary on 15 September that the blockade was already having a direct effect. It had cut Germany off from 50% of her normal imports of nickel, cotton, tin, oil and rubber, and since the war's beginning she had also lost access to French iron ore, making her extremely reliant on Sweden for this vital material.

Germany now looked to Romania for a large part of the oil she needed and to Russia for a wide range of commodities. In fact, apart from allowing Hitler to secure his eastern borders and annihilate Poland, the Nazi-Soviet Pact brought Germany considerable economic benefits. As well as providing refueling and repair facilities for German U-boats and other vessels at its remote Arctic port of Teriberka

, the Russians – 'Belligerent Neutrals' in Churchill's words – also accepted large quantities of wheat, tin, petrol and rubber from America into its ports in the Arctic and Black Sea and, rather than transport them over the entire continent, released identical volumes of the same material to Germany in the west. Before the war total US exports to Russia were estimated as less than £1m per month; by this stage, they were known to exceed £2m per month. From the outset, although they had formerly been hated enemies, large-scale direct trade took place between the two countries because both were able to offer something the other wanted. Germany lacked the natural resources Russia had in abundance, whereas Russia was at that time still a relatively backward country in want of the latest technology. By the end of October 1939 the Russians were sending large quantities of oil and grain in return for war materials such as fighter aircraft and machine tools for manufacturing in a deal valued at 150 million Reichmarks a year.

These losses included 112 British and 12 French vessels, but also demonstrated the disproportionate rate of loss by neutral nations.

 to Germany, had also lost 7 ships, yet all these countries continued to trade with Germany. Churchill was endlessly frustrated and bemused by the refusal of the neutrals to openly differentiate between the British and German methods of waging the sea war, and by their determination to maintain pre-war patterns of trade, but stopped short of condemning them, believing that events would eventually prove the Allies to be in the right. He commented;

At present their plight is lamentable and will become much worse. They bow humbly in fear of German threats of violence, each one hoping that if he feeds the crocodile enough the crocodile will eat him last and that the storm will pass before their turn comes to be devoured. What would happen if these neutrals, with one spontaneous impulse were to do their duty in accordance with the Covenant of the League [of Nations] and stand together with the British and French Empires against aggression and wrong?.


The neutral commerce which Churchill found most perplexing was the Swedish iron ore trade
Swedish iron ore during World War II
Swedish iron ore was an important economic factor in the European Theatre of World War II. Both the Allies and the Third Reich were keen on the control of the mining district in northernmost Sweden, surrounding the mining towns of Gällivare and Kiruna...

. Sweden provided Germany with 9m tons of high grade ore per year via its Baltic ports, without which German armaments manufacture would be paralyzed. These ports froze in the winter, but an alternative route was available from the Norwegian port of Narvik from which the ore was transported down a partially-hidden sea lane (which Churchill called the Norwegian Corridor) between the shoreline and the Skjaergaard (Skjærgård), a continuous chain of some 50,000 glacially formed skerries (small uninhabited islands), sea stacks and rocks running the entire 1,600 km length of the west coast. As in WW1, the Germans used the Norwegian Corridor to travel inside the 3 nautical miles (5.6 km)-wide neutral waters where the Royal Navy and RAF were unable to attack them. Churchill considered this to be the 'greatest impediment to the blockade', and continually pressed for the mining of the Skjaergaard to force the German ships to come out into the open seas where Contraband Control could deal with them, but the Norwegians, not wishing to antagonise the Germans, steadfastly refused to allow it.

Even so, by early October the Allies were growing increasingly confident at the effectiveness of their blockade and the apparent success of the recently-introduced convoy system. A convoy of 15 freighters arrived in British ports unscathed from Canada bringing half a million bushels of wheat, while in France more important ships arrived from Halifax in another convoyed group. The French claimed that of 30 U-boats sent out in Germany’s first major offensive against Allied shipping, a third had been destroyed, and Churchill declared that Britain had seized 150,000 more tons of contraband than was lost by torpedoing.

Neutral ships were warned against joining Allied convoys, Scandinavian merchants were ordered to use the Kiel Canal to facilitate the German's own Contraband Control and the US City of Flint, which had rescued survivors of the Athenia became the first American ship captured as prize of war by the Germans, although the episode proved farcical and the ship was eventually returned to its owners.

, and when a large whale was found near four German mines on the Belgian coast with a huge hole in its belly. Over the weekend of 18–21 November six other neutral ships were sunk off the English coast, including a 12,000 ton Japanese liner.

Eventually, a method of de-magnetising ships, known as ‘degaussing’was developed, which involved girding them in electric cable, and was quickly applied to all ships. Other means of minesweeping were also developed, whereby the mines were exploded by patrolling ships and aircraft fitted with a special fuse provocation apparatus.

The export ban

From early December 1939 the British began preventing German exports as a reprisal for the damage and loss of life caused by the German magnetic mines. Chamberlain said that although he realised this would be detrimental to the neutrals, (Norway got nearly all its coal from Germany) the policy was in strict adherence to the rules of law and that whereas Germany's use of mines and submarine warfare had already caused many innocent deaths regardless of nationality, no loss of life had been caused by the exercise of British sea power. Before the war, 70% of Germany's export trade was with European countries, mostly Holland, France and England, but the Ministry estimated that Germany's remaining annual exports were worth £44m to South America, £19m to the Far East, £15m to the US, and that although nothing could be done to prevent the overland exports to Scandinavia, Italy, Russia and the Balkans, it was believed that German sea trade could be reduced by 45% by the measure.

Angry at the British export ban, the German Government accused the British of having deliberately sunk the Simon Bolivar, lost on 18 November with the loss of 120 people, including women and children. They advised neutrals to shun British waters and trade with Germany, declaring that because of the defensive minefields and contraband control, British waters were not mercantile fairways subject to the Hague Convention regulating sea warfare, but military areas where enemy ships of war must be attacked. Prompted by Germany, all the neutrals protested, but the overall effect was to slow the flow of neutral shipping to a standstill. The Nazi leadership later grew bullish at the apparent success of the mine strategy and admitted they were of German origin, stating that "our objectives are being achieved."

In Berlin, William Shirer recorded in his diary that there were signs of a rush to convert currency into goods to guard against inflation, but that although the blockade now meant that the German diet was very limited, there was generally enough to eat and people were at that point rarely going hungry. However, it was no longer possible to entertain at home unless the guests brought their own food and though restaurants and cafes still traded they were now very expensive and crowded. Pork, veal and beef were rare, but in the early months there was still adequate venison, wild pig and wildfowl shot on estates and in forests. Coal was now very difficult to obtain however, and although sufficient crayfish were imported from the Danubian nations to allow an enjoyable festive meal, people went cold that Christmas. In fact, Germany produced large volumes of very high quality coal in the Saar region, but much of it was now being used to produce synthetic rubber, oil and gas. There were reports that Germany, which badly needed to raise foreign currency had been trying to export bicycles and cars to adjacent countries without tyres. The average German worker worked for 10 hours a day 6 days a week; but although he may have had enough money to buy them, most items were not available, and shops displayed goods in their windows accompanied by a sign saying 'Not For Sale'

Such was the belief in the supreme strength of the Royal Navy that some thought that the blockade might now be so effective in restricting Germany’s ability to fight that Hitler would be forced to come to the negotiation table. The British Contraband Control did allow one delivery to Germany, however – a large quantity of rat poison and half a ton of overripe Gruyere Cheese!

Meanwhile, at the beginning of 1940 there were still 60 German merchant ships alone in South American harbours, costing £300,000 per month in port and harbour dues, and Hitler eventually ordered them all to try to make a break for home. Up to the end of February 1940 about 70 had tried to get away, but very few reached Germany. Most were sunk or scuttled, and at least eight foundered on rocks trying to negotiate the way down the unfamiliar and hazardous Norwegian coast. The Germans tended to prefer to sink the ships themselves rather than allow the Allies to capture them, even at risk to those aboard. Such was the case of the Columbus, Germany's third-largest liner at 32,581 tons, and the Glucksburg, which ran herself ashore on the coast of Spain when sighted. Another, the 'Watussi', was sighted off the Cape by the South African air force and the crew immediately set her on fire, trusting the aircrew to bring aid to the passengers and crew.

, which even her enemies believed, Germany was unable to afford a prolonged war. In order to buy from abroad without credit or foreign exchange (cash), a nation needed goods or gold to offer, but the British export ban prevented her from raising revenue. In WW1, even after two years of war Germany still had gold reserves worth 2.5m marks and over 30 billion marks invested abroad, giving her easy access to exports. By this early stage of WW2, her gold reserves were down to around half a billion marks and her credit was almost nil, so any imports had to be paid for by barter, as with the high-technology equipment sent to Russia or coal to Italy.

 in the west, Hitler ordered that delivery of goods in payment to Russia should take priority even over those to his own armed forces. After the fall of France Hitler, intending to invade Russia the following year, declared that the trade need continue only until the spring of 1941, after which the Nazis intended to take all they needed.

As more U-boats were commissioned into the German navy, the terrible toll on neutral merchant shipping intensified. After the first 6 months of the war, Norway had lost 49 ships with 327 men dead; Denmark 19 ships for 225 sailors killed and Sweden 32 ships for 243 men lost. In early March Admiral Raeder was interviewed by an American correspondent from NBC

 regarding the alleged use of unrestrained submarine warfare. Raeder maintained that because the British blockade was illegal, the Germans were entitled to respond with ‘similar methods’, and that because the British government had armed many of its merchant ships and used civilians to man coastal patrol vessels and minesweepers, any British ship sighted was considered a legitimate target. Raeder said that neutrals would only be liable to attack if they behaved as belligerents i.e. by zig-zagging or navigating without lights. The paradox with this argument – as the neutral countries were quick to point out – was that Germany was benefiting from the very same maritime activity they were trying so hard to destroy.

On 6 April, after the sinking of the Norwegian mail steamer 'Mira', the Norwegian Foreign Minister Professor Koht, referring to 21 protests made to belligerents about breaches to her neutrality, made a statement about the German sinking of Norwegian ships by U-boats and aircraft. "We cannot understand how men of the German forces can find such a practice in accordance with their honour or humanitarian feelings". A few hours later another ship, the Navarra was torpedoed without warning, with the loss of 12 Norwegian seamen, by a U-boat which did not stop to pick up survivors.

Intensification of the blockade

Despite impressive statistics of the quantities of contraband captured, by the spring of 1940 the optimism of the British government over the success of the blockade appeared premature and a feeling developed that Germany was managing to maintain and even increase imports. Although the MEW tried to prevent it, neighbouring neutral countries continued to trade with Germany. In some cases, as with the crucial Swedish iron ore trade, it was done openly, but elsewhere, neutrals secretly acted as a conduit for supplies of materials that would otherwise be confiscated if sent directly to Germany.

A third of Dutchmen derived their livelihood from German trade, and Dutch traders were long suspected of acting as middle men in the supply of copper, tin, oil and industrial diamonds from America. Official figures showed that in the first 5 months of war, Holland’s imports of key materials from the US increased by £4.25m, but also Norway's purchases in the same area increased threefold to £3m a year, Sweden’s by £5m and Switzerland’s by £2m. Prominent in these purchases were cotton, petrol, iron, steel and copper – materials essential for waging war. While some increases may have been inflationary, some from a desire to build up their own armed forces or to stockpile reserves, it was exactly the type of activity the Ministry was trying to prevent.

American companies were prevented from openly supplying arms to belligerents by the Neutrality Acts, (an amendment was made on 21 September in the form of Cash and Carry

) but no restrictions applied to raw materials. During the last 4 months of 1939, exports from the USA to the 13 states capable of acting as middlemen to Germany amounted to £52m compared to £35m for the same period in 1938. By contrast, Britain and France spent £67m and £60m in the same periods respectively, and according to a writer in the New York World Telegram, exports to the 8 countries bordering Germany exceeded the loss of US exports previously sent directly to Germany.

s, oil-bearing nuts, maize, wheat, meat and tobacco. Germany also made big purchases in Greece and Turkey and viewed the region as part of its supply hinterland. Before the war, Britain recognised Germany’s special interest in the region and took a very small percentage of this market, but now, via the United Kingdom Commercial Corporation they used their financial power to compete in the Balkans, the Netherlands and Scandinavia, underselling and overbidding in markets to deprive Germany of goods, although Germany was so desperate to maintain supplies that they paid considerably over the normal market rate.

Commercial agreements were negotiated with Spain, Turkey, and Greece, aimed at limiting material to Germany.

The first bombing of the Ruhr

Shortly after the German invasion of the Low Countries and France, the British took the first tentative steps towards the opening of a strategic air offensive aimed at carrying the fight to Germany. On the night of May 15/16 1940, RAF Bomber Command, which until that point had been used for little more than attacking coastal targets and dropping propaganda leaflets, set off on a night time raid on oil production and railway marshalling yards in the Ruhr

. Under the new plan, weapons could now be bought by any belligerent providing they paid up front and took responsibility for delivery, but whereas Germany had virtually no foreign exchange and was unable to transport much material across the Atlantic, Britain had large reserves of gold and foreign currency, and while U-boats would be a threat, the likelihood was that her vast navy would see the good majority of equipment safely delivered to port.

The US now accepted it needed to increase spending for its own defense, especially with the growing threat of Japan, but there was real concern that Britain would fall before the weapons were delivered. Despite the success in evacuating a third of a million men at Dunkirk and the later evacuations from St Malo and St Nazaire, the British army left behind 2,500 heavy guns, 64,000 vehicles, 20,000 motor cycles and well over half a million tons of stores and ammunition. To help in the interim, Congress agreed to let Britain have a million mothballed First World War rifles, stored in grease with around fifty rounds of ammunition for each. But, following the British attack on the French fleet at Oran on 4 July to prevent it from falling into German hands, the British were proving they would do whatever was necessary to continue the fight, and Roosevelt was now winning his campaign to convince Congress to be even more supportive of Britain, with the Destroyers for Bases Agreement

Compulsory Navicerts

Because of Germany's new proximity on the west European coastline and the decrease in shipping traffic, ships which would normally have been used for patrolling the high seas were diverted to more urgent tasks. Britain discontinued its contraband control bases at Weymouth and The Downs and removed all but a skeleton staff from the control base at Kirkwall to continue searching the few ships bound for Sweden, Finland, Russia and her recently annexed Baltic satellites.

The Navicert system was greatly extended, introducing compulsory Navicerts and ships' warrants in an attempt to prevent contraband being loaded in the first place. Any consignment going to or from ports without a certificate of non-enemy origin and any ship without a ships Navicert became liable to seizure

The lost Dutch and Danish supplies of meat and dairy products were replaced by sources in Ireland and New Zealand. Canada held a whole year’s surplus of wheat, while the U.S. reserve was estimated to be the greatest in history, but Britain was suffering very heavy shipping losses as a result of expanding U-boat numbers. Virtually all Dutch and Belgian ships not captured by the Germans joined the British merchant fleet, which together with the tonnage contributed by Norway and Denmark added about one-third to Britain’s merchant marine, giving them a large surplus of vessels. To prevent the enemy gaining a route to acquire supplies, the occupied countries and the unoccupied (Vichy) French zone immediately became subject to the blockade, with severe shortages and extreme hardship quickly following. Although the Ministry resisted calls that the embargo be extended to some neutral countries, it was later extended to cover the whole of metropolitan France

. Despite attempts to transport it away before capture, occupied nations' gold reserves were also looted, along with huge numbers of artworks, many of which have never been recovered.

Occupied countries were subjected to relentless, systematic requisitioning of anything Germany required or desired. This began with a vast physical looting, in which trains were requisitioned to carry to Germany all movable property such as captured weaponry, machinery, books, scientific instruments, art objects and furniture. As time went on other miscellaneous items such as clothing, soap, park benches, garden tools, bed linen and doorknobs were also taken. The looted goods were taken to Germany mainly by trains, which themselves were mostly kept by Germany.

Immediate steps were also taken towards the appropriation of the best of the conquered nation's food. Decrees were proclaimed to force farmers to sell their animals and existing food stores, and while in the beginning a percentage of each year’s crop was negotiated as part of the armistice terms

The Germans also gained the occupied country's natural resources and industrial capacity. In some cases these new resources were considerable, and were quickly reorganized for the Nazi war machine.

, though the British, foreseeing the seizure, restricted the supply of raw tin leading up to the invasion, so the amount gained was only around a sixth of a year's supply (2,500 tons) for Germany.

But by far the biggest prize was France. German memories of the Versailles Treaty and of the turbulent years of reparations, food shortages and high inflation during the years immediately after World War I caused wealthy France to be treated as a vast material resource to be bled dry, and her entire economy was geared towards meeting Germany’s needs. Under the armistice conditions she had to pay the billeting costs of the occupying garrison and a daily occupation indemnity of 300 to 400 million francs. The occupied zone contained France's best industries, with a fifth of the world's iron ore in Lorraine, and 6% of its steel production capacity. Germany's heavily overburdened railway network was reinforced with 4,000 French locomotives, and 300,000 (over half) of her freight cars.

She also had around 2/3 of Europe’s industrial capacity but lacked the necessary raw materials to feed the plants, many of them working at low capacity or closed because of RAF bombing, the general chaos and the flight of the populations.

From the beginning of the war, Germany experienced massive labour shortages and as time went by the occupied nations labour forces were virtually enslaved, either to work in factories to supply the Reich or sent to Germany to work in the factories or farms there. In Germany herself, there was a chronic shortage of men to work the fields and 30,000 agricultural labourers were brought in from Italy along with thousands of Polish slaves. The pre-war stockpiles of goods were running down and more ersatz substitutes were being used. In addition Germany remained cut off by the blockade from oversea supplies, such as copper from Chile, nickel from Canada, tin and rubber from the East Indies

. Besides the Rumanian supply, his own synthetic industry produced 600,000 tons per year, and another 530,000 came from Poland. Russia was known to have enormous reserves of oil and gas but had chronically underdeveloped extraction systems, and though there was talk of German engineers going to reorganize them, it would take around two years before large quantities would begin flowing.

The Battle of Britain

Hitler’s best chance of beating the blockade was by knocking Britain out of the war. By far Britain’s best weapon was her navy, which not only enforced the blockade, but also, despite the attempts of the U-boats and aircraft, continued to largely control the seas and keep her supplied with most of her needs. Her vast empire gave her formidable resources to draw on, excellent foreign credit facilities and gold reserves, and British rationing was nowhere as severe as in Germany. The only rationing introduced immediately at the war’s beginning was petrol. Bacon, butter and sugar followed on 8 January 1940, meat on 11 March, with tea and margarine in July. It was not until U-boat successes in the 2nd Battle of the Atlantic began severely restricting convoys in late 1940 that rationing became more widespread, and even then many workers and children still had school meals and work canteens to supplement their rations, which made a significant difference to the amount of food they actually received. Photographs of abundant fruit markets, butchers, fishmongers and grocers were placed in foreign publications to prove to American and Commonwealth readers that Britain was not, as the Nazis claimed, starving. Britain did rely on imports for a large proportion of its foodstuffs and, even with the widespread 'Dig for Victory' campaign and the use of women farm workers, could only produce around two-thirds of its needs.

 continued to unload food and war goods for Britain and to load cargoes for export. With no passenger trade, and with all Scandinavian and continental sea traffic suspended, the port was far less busy than normal, but as many as 35,000 men still filled the warehouses with grain, tobacco, flour, tea, rubber, sugar, meat, wool, timber and leather every day throughout August 1940. British aircraft factories, led by the Minister of Aircraft Production, Lord Beaverbrook worked around the clock to greatly increase production and prevent a collapse of the RAF. On 16 September Time Magazine wrote "Even if Britain goes down this fall, it will not be Lord Beaverbrook's fault. If she holds out, it will be his triumph. This war is a war of machines. It will be won on the assembly line".

In an effort to force Britain into submission, the Luftwaffe concentrated its efforts on factories, ports, oil refineries and airfields. By mid-August the attacks were becoming increasingly co-ordinated and successful, and the RAF was losing more fighters and pilots than could be replaced. On 24 August, at the height of the battle, bombers sent to attack Fighter Command installations and oil refineries on the outskirts of London killed civilians in houses in central London through a navigational error, although many believed the bombing was deliberate. In spite of opposition from the air ministry, Churchill ordered the bombing of Berlin

Britons were pleased as it showed Britain was able to hit back, and the next day Berliners were reported to be stunned and disillusioned; Goering, who had said it would never happen, was ridiculed by both sides. When the bombing continued, the Nazi leadership ordered the Luftwaffe to begin bombing British cities in the belief that this would damage civilian morale so much that Britain would sue for peace, a major error.

European food shortages

Despite Germany's industrial gains, food was another matter. Even in peace, Europe was unable to feed itself, and although Germany now held two-fifths of the green fields of Europe, Germans found that despite decrees forcing farmers to sell their produce and livestock and outright requisition, in terms of food the occupied lands represented a net drain on their resources that could not be made good.

While Denmark, the 'Larder of Europe', produced massive quantities of bacon, eggs and dairy products, this was heavily dependent on imports of fertilizer from Britain. Before very long, livestock was being slaughtered because of a lack of fodder

 – the pigs so undernourished that they broke their legs walking to slaughter. Danish farmers paid large taxes, and merchant sailors were driven to work as labourers in Germany because of the blockade. Likewise Holland, with its 2.7m cattle, 650,000 sheep, half a million pigs, and huge surplus of butter, cheese, meat, milk, margarine and vegetable oils, depended on Britain for its animal fodder. Much of the arable land had been ruined by the opening the dikes during the Nazi invasion and many farmers refused to sell the Germans cattle, but soon there was such a meat shortage that the authorities had to confiscate bootlegged dog-meat sausages. Because the Germans forced Dutch fishermen to return to port before dark there was also a shortage of fish, and although Dutch overseas possessions were among the world's main providers of tobacco, it could not breach the blockade.

 and wheat systematically stripped away, and with few farmers left on the land, conditions quickly grew worse. Norway, with extensive mountainous areas relied on imports for half its food and all its coal; shortages and hunger quickly effected Belgium which, despite being densely populated and producing only half its needs, was still subjected to the widespread confiscation of food.

France, normally able to feed itself, now had an extra 5 million refugees from other countries to care for. When the Germans stripped the farms of half a million horses and mules for their army, causing a large drop in agricultural productivity, they also took 11% of remaining food stocks, a million tons. The Germans held 1,500,000 French prisoners of war as hostages, feeding them on bread and soup so thin that grass was added to bulk it up, and most items were now heavily rationed, with a worker entitled to a daily diet of only 1,200 calories; many people rode bicycles into the countryside during the weekend to scavenge for food. German soldiers got double rations, but this was still only a modest daily diet, similar to that served to inmates in American prisons.

Even in the normally plentiful Balkan region there were now food shortages caused by an extremely hard winter in the east and flooding of the lower Danube which devastated the agricultural plains and prevented the planting of crops.

Britain's Bomber Command continued to attack German strategic targets, but the task of bombing Germany was made much harder by the loss of the French airfields as it meant long flights over enemy-held territory before reaching the target.

Humanitarian aid in Europe

In January Herbert Hoover's National Committee on Food for the Small Democracies presented the exiled Belgian Government in London with a plan he had agreed with the German authorities to set up soup kitchens in Belgium to feed several million destitute people. Under the plan, the Germans agreed to supply 1m bushel

s (1 US bushel = 8 US gallons, about 27 kg for wheat) of bread grains each month, and the committee was to provide 20,000 tons of fats, soup stock and children's food. However, Britain refused to allow this aid through their blockade. Their view, which many in America and the occupied countries supported, was that it was Germany's responsibility to feed and provide for the people she conquered, and that the plan could not avoid indirectly helping Germany; if aid were given, this would free German goods for use elsewhere.

Hoover said that his information indicated that the Belgian ration was already down to 960 calories – less than half the amount necessary to sustain life – and that many children were already so weak they could no longer attend school, but the British disputed this. Even so, many Americans were appalled by the continuing hardship. There were 16m French Americans alone, and by early March at least 15 different organizations – collectively known as the Coordinating Council for French Relief – were distributing aid in France through The American Friends Service Committee, while the Quaker Committee also distributed around $50,000 worth of food, clothing and medical supplies a month throughout France.

Supplies are suddenly cut down regardless of the amount stored to scare the population and extra rations are suddenly granted to boost morale in a bad time. Food statistics are guarded like bomber planes. To the Nazis, food is a beautiful instrument... for manoeuvring and disciplining the masses.


By this time there were increasing reports of Vichy French vessels in the Mediterranean running the British blockade from North African ports and ignoring the orders of the British Contraband Control to stop and submit to search. Vichy Vice-Premier Admiral Darlan declared that the Vichy merchant marine had so far brought through the blockade 7m bushels of grain, 363,000 tons of wine, 180,000 tons of peanut oil together with large amounts of fruit, sugar, cocoa, meat, fish and rum.

Lend-Lease

Despite the effects of her blockade, there was no debate about America’s resolve to feed Britain herself, and she was able to, with record harvests. But Britain, having already sold £1000 million of her foreign investments and taken on another £3000m in loans to pay for war materials was now feeling the financial strain of the war.

'. Although America did not enter the war for another nine months, she could no longer claim to be completely neutral and Hitler immediately ordered U-boats to attack US vessels. On 10 April the destroyer USS Niblack, which was picking up survivors from a Dutch freighter that had been sunk detected that a U-boat was preparing to attack, and launched depth charges to drive it away. This was the first direct action between Germany and America of WW2. The next day the US began regular patrols at sea.

Effects on South American trade

The world's blockades had a severe impact on patterns of world trade as a whole. On the outbreak of war, many South American countries expected to make big profits supplying the belligerents as in World War 1. Nearly all of Bolivia's copper, lead, tin and silver was exported to Europe, while Uruguay and southern Brazil supplied wool and canned and frozen beef. Argentina had 84% of the world supply of flaxseed, nearly all of which was exported, along with much of its wheat (23% of world supply), its corn (71%) and beef (50%). But with the stalemate of blockade and counter-blockade, total foreign trade actually plummeted and large surpluses piled up. In early February 1941 the main exporting Plata nations (Argentina, Brazil, Uruguay, Paraguay and Bolivia) held a conference in Montevideo

 to discuss ways of improving trade between themselves and the rest of the continent. Apart from some Parana pine, tea and cereals, there was very little inter-Plata trade, and delegates eventually agreed a number of measures, such as easier currency exchange rules, finance for poorer nations, improved transport links between countries – particularly those landlocked – and lower customs barriers in order to demonstrate that they were not entirely reliant on overseas trade and American dollars to survive.

On 22 June 1941 Churchill proclaimed that Britain would bomb Germany night and day, in ever increasing numbers, but because of the size of Germany and because the fleet continued to be eroded by planes going overseas, Bomber Command remained too weak for effective attacks on the German war machine. The new directives called for attacks on rail transport in the Ruhr to disrupt German economy, but this was a stop gap policy; The planes were too small, carried too light a bomb load and navigation was also shown to be faulty. Following losses of 10% during a raid on 7 November the RAF was ordered to conserve and build up its forces for a spring offensive, by which time a new navigation aid known as GEE

, and soon threatened Australia far to the south.

Because she was an island, the blockade of Japan was a fairly straightforward matter of sinking the transport ships used to ferry materials from the occupied lands to the home islands, and remained a largely American affair. The Japanese began with a barely-adequate 6.1m merchant tons which American submarines and aircraft gradually whittled away until only 1.5m tons remained. The steady toll of attrition against her merchant marine was a major factor in Japan's eventual defeat, but the Allies agreed that the situation was far more complex with Germany, where a range of measures including strategic bombing would be required to achieve final victory.

, the new department was made responsible for the procurement and production of all imported materials necessary both to the war effort and the civilian economy. The Proclaimed List – a US equivalent to the British Statutory List – was compiled and, under British direction, the United States Commercial Corporation was formed to begin making preclusive purchases of strategic materials such as chromium, nickel and manganese to supply future Allied needs and to prevent them from reaching the Germans.

From the start there was close co-operation between the parallel American and British agencies, over economic warfare measures, intelligence gathering and the later Safehaven Program. The American Embassy in London acted as the base for the American BEW activities in Europe and was organized in March 1942, "to establish a more intimate liaison between the manifold economic warfare activities centered in the Ministry of Economic Warfare and comparable activities in the United States Government." BEW personnel sat on the Blockade Committee on equal terms with their British counterparts, undertaking the routine work of handling Navicerts, ships permits and defining contraband. The embassy division worked with MEW in the development of new war trade agreements and the re- negotiation of existing overseas purchase - supply contracts. Together they attempted to persuade the remaining neutrals – Portugal, Spain, Sweden, Turkey, Switzerland (and Argentina) – that by supplying Germany with the materials it needed they were prolonging the war, and over time a number of measures were tried to pressure these countries into reducing or ending trade with the Axis, with varying degrees of success:

Portugal

, another member of the wolframite series of tungsten ore minerals), annually providing Germany with at least 2,000 metric tons between 1941 and mid-1944, about 60 percent of her total requirement.

Britain was Portugal's largest trading partner and had the right to force her to fight on her side under a 500 year old alliance, but allowed her to remain neutral; in return Portugal allowed credit when Britain was short of gold and escudos, so that by 1945 Britain owed Portugal £322 million. Germany was Portugal's second-largest trading partner, initially paying for exports with consumer goods, but after 1942 increasingly with looted gold, which the Allies warned was liable to confiscation after the war. Portugal also allowed Germany generous credit terms, partly because after the fall of France the presence of a direct land route enabled Germany to threaten Portugal with invasion if she curtailed critical exports. The Allies, who also bought Portuguese tungsten, believed that if they could persuade the Portuguese to stop selling the ore the German machine-tool industry would very quickly be crippled and she would be unable to continue to fight. Because Portugal depended on the U.S. for petroleum, coal and chemical supplies, the Allies' economic warfare agencies considered achieving their aim by embargoes, but hesitated because they also wanted access to Portuguese military bases on the Azores

Spain

Since before the war, pro-Nazi Spain had suffered chronic food shortages which were made worse by the blockade. The Allies used a variety of measures to keep Spain neutral, such as limiting her oil supply and making trade deals at critical times to provide her with much-needed foreign exchange to buy food from South America. On 23 November 1940 Churchill wrote to Roosevelt to inform him that the peninsula

 was now near starvation point, and that a US offer to provide a month by month supply of food might be decisive in keeping Spain out of the war.

, continued to supply Germany with war materials, among them mercury and tungsten. Spain, the world's second-largest producer of tungsten after Portugal, provided Germany with 1,100 metric tons of the ore per year between 1941 and 1943 (between them Spain and Portugal provided 90% of Germany’s annual 3500 tons requirement) As a result of Allied economic measures and Germany defeats, by 1943 Spain adopted a more genuinely neutral policy. The Allied strategy with Spain was identical to that of Portugal: buy enough tungsten to satisfy the export need and prevent the rest reaching the enemy by whatever means. Britain and the US again had the option of launching an oil embargo on Spain but hesitated for fear of forcing Franco to side with Germany militarily.

Sweden

Sweden had long been Germany’s main source of high quality iron ore and ball bearings, and continuation of supplies from the port of Narvik, which the British tried to stop with Operation Wilfred
Operation Wilfred
Operation Wilfred was a British naval operation during World War II that involved the mining of the channel between Norway and her offshore islands in order to prevent the transport of swedish iron ore through neutral Norwegian waters to be used to sustain the German war effort...

 was one of the factors which led to the German occupation of Norway. Allied economic warfare experts believed that without the Swedish exports the war would grind to a halt, but Sweden was surrounded by Axis countries and by those occupied by them, and could have herself been occupied at any time if they failed to give Germany what she wanted.

The U.S. and Britain were sympathetic to Sweden’s difficult position and of her attempts to maintain her neutrality and sovereignty by making important concessions to the Nazis, such as continuing to export timber and iron ore and by allowing the Germans use of their railway system, a privilege which was heavily abused. There was a general belief however, that Sweden went too far in accommodating the Nazi regime. In particular, the U.S. abhorred the use of Swedish ships to transport the ore to Germany and of her allowing Germany to transport soldiers and war materials across Sweden and through the Baltic under Swedish naval protection. Sweden received very little by way of imports due to the various blockades, and the Allies tried to use offers of a relaxation to persuade her to reduce her assistance of Germany, which they believed was actively prolonging the war. Churchill himself believed that Sweden could be instrumental in defeating Germany and after the heavy German defeats at Stalingrad and Kursk

The Battle of Kursk took place when German and Soviet forces confronted each other on the Eastern Front during World War II in the vicinity of the city of Kursk, in the Soviet Union in July and August 1943. It remains both the largest series of armored clashes, including the Battle of Prokhorovka,...

 in 1943 the Russians became vocal in calling on Sweden to do more to aid the Allies.

Turkey

Despite signing a military alliance with Britain and France in October 1939, Turkey, like Sweden, Spain and Portugal spent the war keeping both sides at arms length while continuing to supply them with their war needs. Despite the German occupation of the Balkans in spring 1941, no military action was taken against Turkey, who in October 1941 began selling Germany large quantities of chromite ore

 for the production of chromium. The Turkish chromite ore, which like tungsten was an irreplaceable and essential war material, was the only supply available to Germany, who paid using iron and steel products and manufactured goods in order to draw Turkey into her sphere of influence. Turkey still maintained its good relations with the US and Britain despite the trade, which the economic warfare agencies sought to minimize.

Via its Commercial Corporation, the US engaged in a preclusive buying programme under British direction of its materials, particularly the chromite ore. It also bought commodities, e.g., tobacco, it did not really need, and sent Turkey's armed forces modern equipment under Lend Lease to replace obsolete equipment, to help maintain her neutrality. In so doing the Allies sought to maintain British influence in Turkey, and when the Allies decided, at the Casablanca Conference in January 1943 to attempt to persuade Turkey to enter the war against Germany, Britain was assigned the role of negotiator. Turkey eventually ended trade with Germany and declared war on her in February 1945.

Argentina

Although most South American republics were sympathetic to the Allied cause, the US State Department was frustrated by the attitude of Argentina from the very beginning. Her government refused to cooperate with US economic warfare measures or to sever financial ties with Germany, her main trading partner. Though during the war she doubled her exports of bully beef to the US and to Britain, with whom she had a history of close ties, the government was openly pro-Nazi, particularly after June 1943, and even conspired to overthrow other Latin American governments and replace them with fascist regimes. German agents were permitted to operate and spread propaganda freely and subsidiaries of IG Farben

, drugs, and other chemicals to Germany, and a major aim of the US contraband control was to use US exports to Argentina to put pressure on her government to turn away from Nazi influence and break financial ties.

Switzerland

The German relationship with Switzerland was the most complex of all the neutral countries. Expecting hardship, the Swiss government spent heavily in the years prior to World War II on stockpiling food and buying armaments and, anticipating an invasion, kept its forces constantly mobilised

Despite the Allied sympathy with Switzerland's position, some individuals and companies actively supported the Nazi cause for financial or ideological reasons.

US files show that there was a belief that neutrals that traded with the Axis should be threatened with post-war reprisals, but although the Americans believed that the Swiss trade with Germany justified bombing her, it was also thought that her exports should be cut down without endangering the work of the Red Cross and intelligence work underway in Switzerland.

At the start of 1942 the Allies were yet to achieve a major victory. February was an important month.

On the night of 28–29 March the RAF used incendiaries for the first time to hit factories in Lubeck, an old town with many combustible buildings, but although the British considered it a resounding success production was back to normal a week later. More disaster followed on 17 April during a daylight 'precision' raid on the diesel engine factory in Augsburg. There was little effect on production and, with no fighter cover, 7 of the 12 Lancaster bombers were lost, leading to a return to night bombing.

The 1000-bomber raid

Heavy investment had been made in building up the bomber force, but faith in its potential was beginning to wane, and Harris realised a major propaganda

 success was vital to demonstrate his belief that bombers could be decisive in defeating the enemy.< Harris began pushing for a mass raid using the magic number of 1000 bombers, although in fact the RAF barely had that many. At last, using every plane available including trainee crews, the RAF raided Cologne

The City of Cologne was bombed in 262 separate air raids by the Allies during World War II, including 31 times by the Royal Air Force . Air raid alarms went off in the winter/spring of 1940 as enemy bombers passed overhead. However, the first actual bombing took place on 12 May 1940...

, used in the manufacture of aluminium. From mid-November the RAF began a series of 16 massed night raids on Berlin, but thought the damage was considerable, the raids were less effective than those on the Ruhr and Hamburg. Essen and Bremen also suffered 1,000 plane raids and upwards of 1,000 tons of bombs. In 1942 the RAF dropped 37,000 tons of bombs on German targets, probably three times the weight dropped on Britain in 1940 and early 1941.

On 21 December 1942 the USAAF attacked the Krupp plant in Essen and, although they were unsuccessful at first, demonstrated their intention to paralyse German industry by concentrating on key sectors and persevering until lasting damage was inflicted. Another important target was ball-bearing manufacture, most of which was concentrated at Schweinfurt

The blockade runners

Once new supplies of oil, rubber, and tungsten began flowing from the newly occupied Far East, mutually beneficial barter agreements were agreed whereby the Germans would acquire these vital commodities in exchange for the precision tools, blue prints and ball bearings which Japan badly needed. There had already been some trading of silk

 products early in the European war. Despite the 5600 miles (9,012.3 km) and the land barrier of Russia separating Berlin from Tokyo, by mid-1942 a system of fast blockade runners was set up, the freighters traveling non-stop without showing lights or using their radio to avoid detection. The MEW believed that the first Japanese shipment of rubber reached Germany during the summer of 1942, having initially sailed from Indo-China to West Africa. From there it was transferred to small coastal vessels and ran the blockade to French Mediterranean ports by night. The MEW became concerned at the 'steady trickle' of Japanese blockade runners reaching Europe, which one estimate put at 15 ships by the end of 1942, and on the anniversary of the German and Italian declarations of war on the US, General Tojo expressed his pleasure that Japan was able to contribute the resources captured in the South Pacific to the Axis cause.

Other blockade runners were known to be arriving at the French port of Bordeaux, 70 miles inside the Gironde Estuary

 on the Atlantic coast. The port, also a base for German and Italian submarines, was one of the most heavily defended waterways in Europe, protected by numerous patrol boats, searchlights, shore batteries and thousands of troops. Because of its distance from the sea, a naval excursion was impossible, while the RAF believed that a bombing raid would be far too inaccurate and costly in civilian life and aircraft. The difficulty of stopping the blockade runners became known as the ‘Bordeaux Problem’, and eventually the British decided that a different, more espionage based approach was needed.

On 7th December 1942, Combined Operations launched one of the most famous raids of the war; Operation Frankton
Operation Frankton

 departments meant that at exactly the same time that Operation Frankton was under way, and without their knowledge, the SOE were in the final stages of their own attempt to destroy the blockade runners by deploying a team of French agents led by Claude de Baissac

, posing as painting contractors who planned to carry explosives onto the ships in their baggage. The explosions caused by the commando mission ruined the preparations of the SOE team, who might well have achieved a far more effective destruction of the blockade running vessels but for the Combined Operations raid.

Even so, the combined Allied air forces and navies eventually began to track down the blockade runners. In late 1942, an 8,000-ton cargo ship was caught in the Indian Ocean, where it hoisted a neutral flag and initally gave the name of a neutral vessel but misspelled the name. When the Allied warships opened fire the crew scuttled the ship, and 78 Germans were captured.

By late 1943 the Germans became so desperate for supplies of key commodities that in one incident they sent a large destroyer force out into the Bay of Biscay to protect ships bringing a cargo into Bordeaux, and lost three vessels to Allied action. By May 1944, 15 blockade runners had been sunk and the traffic had virtually ceased apart from submarines carrying very small cargoes. The MEW stated that 45,000 tons of rubber, 1,500 tons of tungsten, 17,000 tons of tin and 25,000 tons of vegetable oils had been destroyed as well as important far-Eastern drugs such as quinine

. The Ministry was also of the view that the strong blockade had probably prevented further large amounts from being transported.

The Greek famine

Potatoes were fried using Greek olive oil and shipped back to Germany, and the tomato crop was hurried to scurvy

-ridden German troops in Africa. One US correspondent commented; "Germany worked like a pack of driver ants, picking Greece clean", but the corrupt, collaborationist government also controlled the black market in whatever food was still available, causing rampant inflation of the drachma, which saw the price of a loaf of bread, where available, reach $15. There were reports of grave-robbing by people desperate to find the money to feed their families, but in the towns there were none of the staple potatoes, figs, raisins or tomatoes available and it was not long before the population began to die in droves from hunger, Cholera, Typhoid and Dysentery. In September 1941 the Greeks appealed for overseas aid, particularly from Turkey. An official declared "We are not asking for food that Turks would eat, but for food they refuse to eat."

 and Piraeus each day, and Italy, which now occupied Greece, was forced to ship 10,000 tons of grain from her meagre domestic supplies, secretly to avoid unrest from her own people. This was still not enough, and eventually international pressure forced Britain to lift its blockade for the first time. In early February, Hugh Dalton of MEW told the House of Commons that Britain and America would send 8,000 tons of wheat to Greece, although there was no guarantee that the relief supplies would find their way to the starving. Dalton said; "There is no guarantee, nor would we pay any attention to one given by the Germans. We are in this case running a risk in view of the appalling conditions caused by the Germans in Greece." From that point on, the Greek Orthodox Church

, through its charity efforts in the United States and the International Red Cross were allowed to distribute sufficient supplies to the Greek people, though the total death toll from the famine was at least 70,000, probably much higher.

By late 1942 there were claims that Germany was paying for deliveries using forged US dollars and had began to default on its Romania trade, receiving deliveries while not supplying the much-needed machinery and war materials in return. Spanish suppliers of oranges and mandarins also refused to ship deliveries until they were paid. With the gradual turn of the war, a number of neutral countries began to take a stiffer line with Germany, in some cases refusing further credit.

 the weather was more favourable but, with the coming threat of invasion, the Germans were intent on stripping the land so the Allies would be left with nothing and be compelled to bring everything across from England. Hermann Goering proclaimed in a speech that under the Nazi New Order, the Herrenvolk were entitled to deprive the occupied peoples of their food, and that whoever starved it would not be the Germans. Rationing remained fierce. Even with coupons, it was impossible to acquire many items. Maximum prices were fixed for everything, but the black market pushed prices 5–15 times beyond the official tariff. Cheap restaurants in big towns served dishes comprising turnip or carrot tops made without any kind of fat, and although householders still received a fair ration of rough wine, all spirits were confiscated for industrial use.

The MEW continued to receive requests for a partial relaxation of the blockade, often in the belief it would make no appreciable difference to the effect on the enemy, but the pleas were steadfastly refused. The MEW believed that any substantial or widespread relaxation of the blockade would inevitably be exploited by the enemy to his own advantage, and declared that they would "not give him that comfort".

With increasing numbers of heavy Lancaster, Stirling and Halifax bombers, which could travel long distances and carry a heavy bomb load, reaching squadrons, Allied leaders increasingly put their faith in the cumulative effect of strategic bombing, but decided at the Casablanca Conference in early 1943 that, as with the British Blitz, the early attempts to disrupt the morale of the German people by saturation bombing of cities had achieved the opposite effect.

Sir Arthur Harris and his USAAF counterpart, Major General Ira Eaker assured Winston Churchill and Franklin Roosevelt that Germany could be bombed out of the war by the end of 1943 on the condition that nothing was allowed to reduce the forces already allocated to the bombardment of Germany. Harris was known for his sharp tongue and lack of remorse for the German civilians being killed by the raids; one of his subordinates said of him. "Oh, we love him, he's so bloody inhuman." Harris believed that the only role for land forces in Europe would be to occupy the Continent after the bombing had defeated Germany. Churchill thought that the experiment of all-out bomber attack was worth trying as long as other measures were not excluded, and while the commanders of the Allied land forces and navies doubted that bombing would defeat Germany, they agreed that the raids would be useful in weakening Germany prior to the invasion of Europe. But only 10% of bombs fell close enough to their targets to be called hits, and heavily-bombed installations often had to be bombed again to knock them out. However, attacks on the already strained German railway system did seriously affect military operations – in early 1943 around 150 locomotives and many freight cars were being destroyed each month.

On the night of 16–17 May 1943 the RAF carried out the famous Dambusters raid (Operation Chastise
Operation Chastise

) to breach the Mohne, Eder and Sorpe dams which supplied the Ruhr industries with hydroelectric power and fresh water needed for the production of steel. The raid, known as 'Operation Chastise' drowned 1,500 people and countless farm animals, but was not as successful as claimed; and half of the 18 bombers were shot down. On 24 July 1943 Hamburg, a major manufacturing centre for Tiger tanks and 88mm guns was virtually destroyed in Operation Gomorrah. Mass attacks a few days later left a large part of the city in ruins, reportedly killing 42,000 people.

In comparison with the RAF, the US 8th Air Force was at that point still small, having dropped less than a tenth the bomb tonnage on Germany as the RAF. But it was growing fast, and had begun to achieve good results. 'Bomber' Harris had great faith in American manufacturing ability and believed that it would be the USAAF, not the RAF, who would eventually deliver the final decisive blows to the enemy. On 1 August the USAAF attacked the Romanian Ploesti oilfields in Operation Tidal Wave as part of the Oil Plan to wear down Axis oil supplies. No loss of production was caused, and losses were heavy: 54 out of 177 bombers were shot down. On 14 October 1943 the 8th USAF carried out the most successful of 16 attacks on the Schweinfurt ball-bearing works but caused only a temporary setback to production and, because the bombers had fighter escort only part of the way, losses were again heavy. This forced a rethink on the self-defending bomber formation and the curtailment of daytime attacks. In November heavy damage was caused by the USAAF to the most important industrial site in Norway, the molybdenum

, had to ask the House of Commons to find another £1 billion to continue. USAAF airpower increased, concentrating its efforts on aircraft production and repair plants in France, Holland, Belgium and Germany. By late October 1943, the MEW believed that German productivity was down 30%, and that half the drop had occurred in the previous six months, but the figures showed the limitations of all bombing, saturation or precision. Many of the installations that had previously been reported as wiped out continued to operate.

In early November the MEW published a summary of the position in the occupied lands, giving an assessment of what the Germans were believed to have appropriated from the territories they conquered in 1940 and 1941. The report estimated that more than $12,800,000,000 had been collected from the occupied territories in occupation costs and other direct charges and continued to be collected at a yearly rate of $4,800,000,000. Poland, the country most harshly treated, had suffered the confiscation of all state properties, all central stocks of textiles, food and livestock. 9,000 factories and 60,000 commercial enterprises were taken over for exploitation, and 80% of the 1942 harvest was sent to Germany. Czechoslovakia had lost its grain, its gold reserves, mines, heavy industries and important textile industry. Her total tribute was given as $1,200,000,000. Dutch industry was by now also under complete German control. State expenditures had almost trebled to pay Germany's occupation and other costs and levies. Belgium, whose government was in exile in Britain, had its entire $260,000,000 gold reserves surrendered by the Vichy regime and by the beginning of 1943 the country's entire stock of 1,500 locomotives and 75,000 trucks had been requisitioned. In Yugoslavia, all cars were seized in 1941, and any bicycles that could be found had been taken by 1942. The country had been partitioned and had suffered, like so many others from inflation caused by the occupation mark system. In Norway the Germans requisitioned personal property right down to woollen blankets, ski trousers and windproof jackets, and in Denmark all trade and industry of consequence was now controlled by Germans.

Troops had also begun seizing furniture and household goods to be shipped back for the use of bombed-out German families. Under Albert Speer, industrial factories were being relocated to Czechoslovakia on a considerable scale, and by the end of 1943, despite a lot of damage to towns – German figures showed that 6.9m people had been bombed out or evacuated – output of war material was greater that ever. In October 1943 the USAAF attacked Ploesti again, but according to German records total loss of petroleum to the end of 1943 had not exceeded 150,000 tons.

1944

By the beginning of 1944 it was clear that the bomber offensive had not delivered the decisive defeat that was promised, and preparations were well underway for the invasion of Europe. Spain, Portugal and Sweden came under renewed pressure to end sales of vital commodities to Germany. In January 1944 the MEW estimated that Spain was still selling Germany 100 tons of tungsten a month. The Spanish Minister for Industry and Commerce defended Spain's position, saying that Spain felt it impossible to deny Germany a commodity which had a very high value in wartime. Britain, who also made considerable purchases of Spanish tungsten, favoured a compromise that would allow Spain to maintain her German tungsten exports at the 1943 level, but the United States demanded a complete ban and the oil embargo was eventually reimposed. Spain agreed to reduce the German exports in May 1944, although the Allies discovered that she continued making clandestine shipments, transporting more than 800 tons of tungsten through to July 1944 and not finally ending the trade until the closing of the Franco-Spanish border in August 1944. Portugal also defended her right to neutral trade, fearing German reprisals such as invasion or the bombing of her cities and shipping if she ceased tungsten shipments; however the US Secretary of State Cordell Hull

 believed that he could have achieved the objective if he had had wholehearted British support.

. The RAF returned to bomb the same targets by night, and the damage was such that Milch informed Speer that the March 1944 output would be only 30% – 40% of February's total. Albert Speer took over aircraft production and managed to perform miracles: the installations were soon back to something like normal capacity, and overall production - including synthetic oil production - was at an all-time high and still rising. The Luftwaffe had around 40% more aircraft than it possessed a year earlier, the construction of new tanks was sufficient to equip new divisions raised for the defence of western Europe and to make good some of the losses in the east.

Although the Allies kept up the round-the-clock pressure, raiding countless lines-of-communications targets in the build-up to the invasion, they were slow to grasp what German commanders were all too aware of – that Germany had plenty of tanks and aircraft and their real achilles heel was the oil supply. In early March the USAF raided the Erkner

 ball-bearing works, scoring 75 direct hits, stopping production for some time, and commenced the "Plan for Completion of Combined Bomber Offensive". The objective now became to halve Axis oil production by attacking the Ploesti oilfields and fourteen synthetic-oil plants in order to deprive Germany of the means to keep its military machines operational.

 and Lutzendorf; they were so badly damaged they could supply no oil for several weeks, being hit again later that month before they returned to production. Albert Speer said later that this was a decisive turning point in the war.

Meanwhile, as a result of the sustained Allied diplomatic pressure, together with the deteriorating German military position, Sweden began to reduce its trade with Germany. But a September 1943 agreement under which she agreed to end ball-bearing exports failed to include a restriction on sales of the high-quality steel used in their manufacture; this allowed the restrictions to be largely by-passed, and the agreement ultimately had little effect on the German war industry. Allied attempts to stop Turkish sales of chromium had begun to have the desired effect, however. In November 1943 Albert Speer declared that without its Turkish chromium imports, Germany's armaments manufacture would come to a halt within 10 months, and Allied threats to subject Turkey to the same economic warfare measures used against other neutrals eventually persuaded her to cease the exports to Germany by April 1944.

Though Germany, with the resources of the conquered territories was still able to produce three times as much steel as Britain, as a result of military action she was beginning to lose other sources of special metals which could not be replaced. On the eastern front, the Red Army had taken back its manganese mines at Balki

, from which the Germans had been getting 200,000 of the 375,000 tons their war industry required each year. In Scandinavia, an important supply of nickel was now prevented from being delivered from Petsamo in Finland, and the mines at Knaben in Norway were no longer providing molybdenum.

The eve of Overlord

During a debate in the House of Lords about the economic war on 9 May 1944, just before D-Day, Lord Nathan told the House:

My Lords, I wish to bring to your minds an almost forgotten Ministry. Back in 1939, in the early days of the war, the Ministry of Economic Warfare was always in the headlines. Then some people thought and some people said that the war could be won by blockade alone without fighting, that Germany would suddenly collapse for lack of fuel, lack of special steels, even lack of food. In a bitter school we soon learnt differently. Even today, though Germany is extremely short of oil, she has enough for actual military operations, and her people are still reasonably well fed. But after those early days we went to the other extreme. Blockade by itself did not do the trick so we put it on one side in our minds. If the early hopes were exaggerated, we must not attenuate the actual achievements. The blockade almost certainly saved us from defeat. It quite certainly made it possible for us to win and has given us the precious time to make ready for the final blow. Some years ago an economic writer put it like this: "The blockade won't make Germany crack, but it will make her brittle." Now she is brittle, our armies can crack her. The blockade is more important now at the climax, on the eve of invasion, when the strain is telling, than ever before. The famished people of Europe must now look to the onward sweep of our advancing Armies coming as liberators and bringing bread in their train.


Lord Selbourne told the house that the effect of the blockade, which may have been slight at first, had been cumulative, and Germany's greatest lack was now in manpower. While Britain was herself importing tens of millions of tons of supplies per year, the enemy was increasingly forced to use ersatz
Ersatz
Ersatz means 'substituting for, and typically inferior in quality to', e.g. 'chicory is ersatz coffee'. It is a German word literally meaning substitute or replacement...

 industries. German civilian motor traffic had practically entirely gone over to producer-gas, which like all ersatz materials was grossly wasteful in manpower, and this, combined with her colossal losses in the field and the need to keep a disproportionately high percentage of its available labour on the land, had produced an acute manpower crisis requiring the use of some seven million foreign slaves in Germany alone. In June 1944 the British finally secured access to the naval bases on the Azores, and the Allies thereafter threatened Portugal with economic sanctions. In turn, Portugal imposed a complete embargo on all tungsten exports to both sides, leaving Germany with only its small supply from Spain, while the Allies had alternative sources in the Far East and South America.

German air defences could no longer protect the installations, and on 12 and 20 June the RAF attacked the Ruhr hydrogenation plants and put the eastern plants completely out of action, causing a rapid drop in production; Speer predicted disaster by September if the situation did not improve. From the beginning of Overlord on 6 June, the Allies enjoyed complete control of the skies over the beachhead, and were able to transport adequate oil across the sea via tanker and use of the PLUTO

The German armies defending Normandy were badly restricted by their inability to bring up adequate fuel for their tanks and could only make troop and supply movements at night. They were also forbidden by Hitler from withdrawing to better positions a few miles inland, and as a result suffered a relentless barrage of heavy calibre gunfire from British and American battleships moored offshore. German commanders increasingly put their faith in the new Messerschmitt 262 jet fighter and the V-weapons to turn the tide. The first V1 flying bomb was launched against England on 13 June 1944, and soon 120 V1s per day were being fired at London, killing large numbers of civilians. By the end of June over 2,000 V1s had been launched; 40% of bomber resources were being redirected towards 'Crossbow

Allied supply problems

After the initial success of D-Day and the breakout from the Normandy beachhead which followed, the advance began to slow due to the constant difficulties of keeping the vast armies supplied. The problem was not getting supplies to the continent, but getting them to forward troops, which might be 500 miles (804.7 km) from supply depots. Each division required 600–700 tons of supplies per day while artillery and mortars used 8 million rounds per month. The speed of advance often meant there was no time to build up an orderly logistical structure and, despite the use of a one-way truck system called the Red Ball Express

, for 5 days at the end of August virtually the entire American and British advance came to a complete halt due to a lack of fuel.

The supply problem was worsened by the Allies' failure to capture a deep-water port able to unload large ships. The Germans, employing their scorched-earth policy, destroyed all dock facilities as they withdrew from the occupied territories in order to deprive the Allies of any logistical advantages. By early September the only remaining undamaged deep-water port was Antwerp in Belgium, and the SOE, under the direction of the Ministry of Economic Warfare (MEW) was given the task of ensuring it was captured intact. The operation, known as Counterscorch, involved sending radio operators into Belgium to liaise with the resistance, keeping them informed of Allied movements and supplying them with weapons and ammunition. At the allotted moment the resistance seized the port, keeping the Germans out until the Allies arrived, and Belgium was liberated in less than a week, although the port of Antwerp itself was not fully operational and capable of landing large cargoes until after the Battle of the Scheldt in late November.

The supply problems also led to disagreements, as each commander pressed for his unit to be given priority. The supreme commander of Allied forces, General Eisenhower wanted to advance on a broad front to overcome the West Wall (Siegfried Line

Loss of Balkan ores

By early October the European military and political position had changed enormously and the MEW provided a statement of Germany's deteriorating position. As a result of military operations in Lorraine and Luxembourg, the withdrawal of Swedish ships from trade with German ports, the closing of Swedish Baltic ports to German shipping, and the loss of supplies from Spain, it was estimated that iron ore supplies had been reduced by 65 per cent compared with 1943. In addition, about 45% of pig iron

Meanwhile, in an attempt to assist the Allies in their liberation of Holland, the exiled Dutch government called for a national rail strike to further disrupt German operations. The German authorities retaliated by placing an embargo on supplies of food into western Holland. This caused severe hardship.

. In the Balkans, the Ploesti oilfields were lost to Germany as an oil source from August 1944, and various opposing paramilitary groups and partisans united behind Marshal Tito. With Soviet help they began pushing Axis forces beyond Yugoslav borders, leading to further German losses of food and metals.

End of Swedish trade with Germany

In August 1944 Sweden determined that the danger to its merchant and naval vessels engaged in the iron ore trade to Germany had become too great, and ceased exports in exchange for permission to import some of her own stores of cotton and wool shut off by the Allied blockade. In November all Swedish trade with Germany officially ended. After six months of negotiations, Switzerland also agreed to trim by one third her $60m yearly sales of machine goods and precision instruments to Germany and to cut sales of ball bearings to 10% and ammunition to 5% of the 1942 total.

By this time, attacks on German fuel installations had been so successful that September's output was 8% that of April, and supplies were soon exhausted, just when fighter production reached its highest level. Allied air commanders next began targeting German transport networks. On 24 September the RAF breached the Dortmund-Ems Canal

, Norway. The ship, known as the 'Lonely Queen of the North' had seen little action through lack of fuel, and spent much of the war moored in a remote fjord. Around this time the RAF began reducing its attacks on synthetic oil production sites because none of the plants were now operating. Only the sites at Leuna and Polotz were still producing any oil, and though in December limited production restarted, further raids quickly put them out of action for good. Once the oil sites were bombed out in late 1944, transport became the primary target. Allied air power was now unstoppable.

In late 1944 the German army launched the Ardennes Offensive, an attempt to split the Allied army, recapture Antwerp and force a negotiated peace. Despite early success, caused in part by severe Allied supply shortages, particularly of fuel, the operation eventually petered out,. This was the last serious attempt by the German army to regain the initiative on land, although the Luftwaffe launched one final offensive with 800 aircraft against Allied airfields in Belgium, Holland and France early in 1945.

1945

At the start of the war Germany's transport system, comprising modern autobahns, excellent railways and a complex network of interlinking canals and rivers was among the best in the world. But after autumn 1943 the connections between industrial centres made attractive bomber targets which when effectively bombed badly affected the distribution of coal, which formed the basis of most military and industrial operations. Soon large parts of Germany’s remaining transport network were paralysed, and the Ruhr became economically isolated from the rest of the Reich.

Ultimately it was the sustained Allied bombing of the transport network which broke Nazi resistance. Despite his incredible efforts at continually reorganising production after each setback, from early 1945 Speer admitted defeat in the armaments battle. German industry was now unable to keep up with the high number of 'Top Priority' weapons programmes, such as the production of the V weapons and calls for 3,000 Me 262 jet fighters and bombers per month. However, many factories maintained production right up to the moment Allied forces arrived at the gates.

By now the V 1 and V2 launch sites were being increasingly overrun, and with the Allies moving towards the Rhine and the Soviet armies rapidly closing in from the east, large numbers of refugees began to congregate in the cities, creating utter chaos. When severe frost and snow came in January, food was declared the main priority, although Germany still maintained the ability to defend its vital installations with formidable numbers of anti-aircraft cannons. From early February 1945 railheads, marshalling yards and transport systems of over 200 small towns, such as Hildesheim

 (IMF). The program provided for immediate measures to prevent any disposition, transfer, or concealment of looted gold or other assets, to deny any safe haven for Nazi looted assets in neutral countries, and for the eventual return of looted artefacts to their original owners. Most neutrals were eventually persuaded to reduce and end trade with Germany.

The Swedish Government adopted tightened exchange control regulations in November 1944 and made great progress in identifying German properties and eliminating German influences from its economy. However, negotiations for the return of looted gold allegedly sent to Sweden by Germany as payment for goods dragged on for many years. Allied estimates of the value of looted gold ranged between $18.5 million and $22.7 million, but although the British, US and French agreed that Sweden’s gold reserves had increased during the war, they were unable to agree how much – if any – of these rises were due to looted gold. Sweden eventually agreed to distribute more than $66 million in liquidated German assets as reparations, including a special $36 million fund at the Riksbank to forestall disease and unrest in Germany and to finance purchases essential for the German economy. It also agreed to provide more than $8 million in gold to make up for that amount of Belgian monetary gold sold to Sweden during the War, but negotiations regarding 8.6 kilograms of Dutch gold ($9.7 million) stalled when Sweden argued that the gold had been acquired before the January 1943 London Declaration on looted gold. In April 1955 the Dutch claim was finally proved conclusive, and Sweden returned about $6.8 million in gold.

Spain acquired a large quantity of gold from Germany, in some cases via Swiss intermediary companies, and negotiations coincided with Allied efforts to ostracize the Franco regime. A number of other countries also downgraded their diplomatic relations with Spain for having openly supported Hitler, and Spain agreed to return an estimated $25 million in official and semi-official German assets in October 1946. Spain agreed to liquidate some $20–23 million of private German assets on the understanding she would keep around a quarter of the proceeds, and signed an agreement in May 1946 to return $114,329 (101.6 kilograms) out of about $30 million in looted Dutch gold that the Allies had identified at the Spanish Foreign Exchange Institute. The Allies publicly acknowledged that Spain had not been aware it was looted, and later Spain returned $1.3 million in gold bars and gold coins it had seized from German State properties at the end of the War. Negotiations continued, but with the coming of the Cold War

 the US softened its approach and released over $64 million in assets frozen since the war, and allowed Spain to use its remaining gold as collateral for private loans.

Because of its close financial ties with Germany, Allied representatives were especially keen to achieve Swiss co-operation. Although Swiss-German trade was generally considered to have ceased after November 1944, some companies, such as the Tavaro Munitions factory at Geneva, Switzerland, clandestinely shipped explosives to Germany, and German assets amounting to one billion francs still remained in Switzerland after November 1945. According to Under-Secretary of State Dean Acheson

, the Swiss later reneged on this agreement, and through the remainder of 1945 showed an unwillingness to embrace the Allied proposals to turn German assets in Switzerland towards the benefit of ravaged Europe and stateless victims of the Holocaust and other Nazi crimes. However, because of its excellent humanitarian record and protection of Allied POWs and other interests, the Allies ultimately decided against taking extreme measures against Switzerland.

The post-war world

Following the end of the war in Europe in late May 1945, large parts of Europe lay completely smashed. Acute food, housing and medical shortages continued for some time and around 10 million refugees housed in temporary encampments or on the roads.

In the two emerging superpowers, Russia and America, post-war productivity rose remarkably by 1948, although the reasons were very different. In Russia, great stimulus was given to emerging industries as a result of frenzied war production, helped in part by advanced industrial plant it took from east Germany after the occupation. America meanwhile, had been under severe depression in 1938, with vast industrial resources lying idle and 20% of the population unemployed. Rearmament, and later war brought these resources to life, which combined with rising investment and no requirement to rebuild their devastated infrastructure kept American industry buoyant, although considerable residual unemployment remained. Much the same situation existed in Canada, whose economy was closely tied to America, and who also suffered no fighteing within its territory. The war changed the pattern of the international economy, leaving the US in a very strong bargaining position, having managed to free up international trade to its benefit as a consequence of Lend–Lease, and forcing the British to agree to currency convertibility.

Britain's economy was badly hit by the abrupt ending of Lend-Lease a few days after the final defeat of Japan in August 1945. During the war Britain lost many of its lucrative export markets and now confronted an annual balance of payments

In the former occupied countries, severe inflation – caused in part by the large amount of money hoarded during the war, particularly by collaborators – caused further spiralling food prices and a persisting black market. A factor aggravating inflation was low productivity, caused in part by a lack of coal. France assumed it would become entitled to large volumes of German coal from the Ruhr as war reparations, but the Americans, who kept France and other countries going with a number of short-term loans and Marshall Aid, began to realise – correctly – that Europe needed the powerhouse German economy to restart growth and prevent the spread of communism, and refused to agree to reparations, the very thing which led to German resentment after WW1 and the rise of Hitler.

In Germany herself, the people were left to start again from almost nothing, partitioned into zones which became east and west Germany for many years by the Allied powers, a time sometimes referred to as Year Zero. Although they faced a massive task, with whole cities to be rebuilt and industries reorganised to peaceful production, within a few years the West German economy achieved a miraculous turn-around, and by 1950 a Wirtschaftswunder
