, seriously depleting Axis strength in the east.

During the months of November, 1942 to February, 1943, the German position in southern Russia became critical. With the encirclement of the German 6th Army at Stalingrad, a huge hole opened up in their lines. Follow-up Soviet forces pushed west, threatening to isolate Army Group A in the Caucasus as well.

 was reduced to desperate measures. Divisions were scraped up by thinning nonthreatened sectors. Noncombat personnel were pressed into service, along with tanks in rear area workshops. Ad hoc units were formed which blunted the Soviet advance spearheads.

In due course, the SS Panzer Corps arrived from France, fresh and up to strength. Other mechanized units such as the 11th Panzer Division arrived from Army Group A, along with the 6th and 17th Panzer Divisions. By February 19, enough German armor was concentrated to launch a pincer-style counteroffensive against the overextended Russian forces, notably Armored Group Popov.

The spring thaw now turned the countryside into a muddy quagmire and both sides settled down to plan their next move.

General Manstein initially believed that the German Army should go on the strategic defensive and deliver strong counterblows with their mobile reserves. He was convinced that the Red Army would deliver its main effort against Army Group South. He proposed to keep the left strong while retreating on the right to the Dnieper River

 under the overall command of Manstein would attack northwards from Belgorod. They planned to meet at Kursk, but if the offensive went well, they would have permission to continue forward on their own initiative, with a general plan to re-establish a new line at the Don River, several weeks' march to the east.

The German commanders favoring the attack were confident and guided by the facts that the distance to Kursk was short, the attacking forces strong, and the Wehrmacht's history was one of always shattering Soviet front lines where it chose to.

Contrary to his recent behavior, Hitler gave the OKH considerable control over the planning of the operation. Over the next few weeks, they continued to increase the scope of the forces attached to the front, stripping other areas of the German line of anything useful for deployment in the operation. They first set the attack for 4 May, but delayed in order to allow more time for new weapons to arrive from Germany. Hitler postponed the offensive several more times. On 5 May, the launch date became 12 June. Due to the potential threat of an Allied landing in Italy and delays in armor deliveries, Hitler set the launch date to 20 June. On 17 June, he further postponed it until 3 July, and then later to 5 July.Source: German Nation Archive microfilm publication T78, Records of the German High Command (Oberkommando der Wehrmacht

made these types of tactics even more effective. Blitzkrieg depends upon a mass of armor concentrated at some weak point, followed by rapid breakthroughs where columns of tanks and mechanized infantry penetrate forward and then curve inward toward each other, trapping the enemy forces in between. Essential to such operations is control of the air space so that one's tanks are not subject to aerial bombardment, but those of the enemy are. Upon encirclement of a portion of the opposing force, defeat follows through disruption of command and supply rather than continuation of a pitched battle

Further supporting the Soviet infantry were 6,000 76.2mm anti-tank guns which were skillfully camouflaged. Gunners were instructed to concentrate their fire on the more vulnerable Panzer IV
Panzer IV

 tanks which formed a majority of the Panzer division strength. The Russian howitzers, mortars and machinegun posts had as their mission to eliminate German infantry attempting to close in on the anti-tank guns. The density of artillery in the salient was unusual. There were more artillery regiments than infantry regiments. The Red Army was determined to grind down the advancing Panzer formations with artillery and anti-tank obstacles in order to slow, stop, and counterattack them.

Further buttressing the Russian infantry were independent armored brigades. Some of these tanks were dug into hull-down positions and used in a static role.

Waiting in reserve for the Germans if they should breach the Soviet lines was the Steppe Front consisting of 4th and 5th Guards, 27th, 53rd and 57th Armies, and the 5th Guards Tank Army.

The Russians massed some 1,300,000 men, 3,600 tanks, 20,000 artillery pieces, and 2,792 aircraft. This amounted to 26% of the total manpower of the Red Army, 26% of its mortars and artillery, 35% of its aircraft, and 46% of its tanks. The Germans received reports of powerful Soviet concentrations in the Kursk area and delayed the offensive to allow for more Panther tanks to reach the front line.

Many of the Soviet forces assigned to the defense of the salient were recent veterans of the Battle of Stalingrad. But the Red Army also added over one million new men in the first half of 1943. Hence the Red Army was comparatively stronger in 1943, while the German army was smaller.

Like the Germans, the Soviets employed numerous deceptions. Dummy positions were constructed. Mock aircraft were placed on false airfields and misleading radio traffic sent to confuse German intelligence. Camouflage for battlefield positions was excellent. Generally, the first warning German units received of the presence of Soviet guns was their own vehicles exploding.

State of the Red Air Force

In the early stages of the war, the Red Air Force, while numerically superior, suffered from an abundance of obsolete designs and insufficient training. Many Soviet pilots learned to fly as civilian members of air clubs set up by the Osoaviakhim.

By 1943, more formal training was introduced and modern aircraft such as the Yakovlev Yak-9

When the Red Army launched their counteroffensive in the north, the German 2nd Panzer Army was attacked by two Soviet Fronts: Brijansk and West. The 107,000 men of the 2nd Panzer Army and some reinforcements in the south brought the Wehrmacht troops to approximately to 950,000 men (approximately 650,000 combat troops). The two Soviet Fronts brought the Red Army to 2,629,458 men (1,987,463 combat troops).

 bombardment in the north and south. This barrage by over 3,000 guns and mortars expended about half of the artillery ammunition for the entire operation. The goal was to delay and disorganize the German attack. In the northern face, the Central Front artillery fired mostly against German artillery positions and managed to suppress 50 of the 100 German batteries they attacked, resulting in much weaker German artillery fire on the opening day of the attack. This bombardment disrupted German units and caused them to attack at different times on 5 July. In the south, the Red Army chose to fire largely against the German infantry and tanks in their assembly areas. This was partially successful in delaying the German attack but caused few casualties.

German onslaught

The 9th Army's attack in the north fell far short of its objectives on 5 July. The attack sector had been correctly anticipated by the Red Army Central Front. Attacking on a 45 kilometre wide front, the Germans found themselves trapped in the huge defensive minefields and needed engineering units to come up and clear them under artillery fire. Although a few Goliath

 and Borgward remote-controlled engineering vehicles were available to clear lanes in the minefields, they were not generally successful. Even when the vehicles cleared mines, they had no on-board marking system to show following tanks where the cleared lanes were. Red Army units covered the minefields with small arms and artillery fire, delaying German engineers clearing manually; German losses were high.

For example, the German 653rd Heavy Panzerjäger Battalion began the attack with 49 "Ferdinand" (known in the West as "Elefant

s rather than permanent losses, they were out of action until they could be repaired. They were also easier for Red Army artillery to knock out permanently. However, since the Germans were advancing, any repairable vehicles could be recovered, repaired, and put back into action. After the first day of attack, the German units penetrated 8 km deep into the Russian lines for the loss of 1,287 killed and missing and 5,921 wounded.

The Germans noted a fundamental flaw in their armored vehicles, particularly the Elefant. Although excellent against any Soviet tank at long to medium range, they lacked secondary armament and were vulnerable to attacks from Soviet slit trenches, once they were separated from the heavy machine gun protection of the lighter tanks, vehicles and infantry. Guderian noted in his diary:
On the second day, the Central Front under Rokossovsky started a counter-attack against the German 9th Army, particularly the XLVI Tank Corps. The Red Army attacked with the 2nd Tank Army and the XIX Tank Corps, but this operational counter-attack was launched too early. Soviet tanks sustained heavy losses in their first combat with Tiger tanks of 505th Heavy Tank Battalion. The 107th and 164th Tank Brigade lost 69 tanks and the Soviet attack was stopped. After the encounter with German Tigers, Rokossovsky decided to dig in most of his tanks and use them as static anti-tank guns.

The next two days of the attack saw heavy fighting around the strong point of Ponyri (on the Orel–Kursk railway), which was one of the most fortified positions in the northern sector. Both sides saw this area as a vital point; a very intense battle took place. The German tanks were awaited by 70 antitank guns per km. On 7 July the 86th and 292nd German Infantry Divisions attacked Ponyri and captured the town after intense house to house fighting. The Soviets counter-attacked and forced the German troops to withdraw temporarily; many counter-attacks by both sides followed and the town changed hands many times. Not before the evening of 8 July did the German units capture most of the town. The heavy Ferdinands were called into action to take Hill 253.5 and succeeded on 9 July. It developed into a battle of attrition with heavy casualties for both sides; Keegan called Ponyri "the new Douaumont

". German units were exhausted, while Russian reserves were committed.

Model decided to pause to rearrange his units. On 10 July, he renewed his attack with additional air support, but his gains were minor. Fresh Soviet formations repelled German attacks and only limited penetrations were achieved; the diary of the 9th Army describes the heavy fighting as a "new type of mobile attrition battle". Model canceled the new attack.

The cancellation of the attack changed German plans; Model accepted that his forces did not have enough power to advance directly through the Soviet strongpoints. He decided to bypass the heights of Ol'chovatka and shift the schwerpunkt to XLVI Panzer Corps. He also decided to use the uncommitted 12th Panzer Division. For the first time in the northern sector, a heavy concentration of tanks was planned. Model's hesitation to use the concept of concentration, which is described as the decisive element of an armored attack, led to a slow advance of the 9th Army. Because of the limited action of the tank units, only 63 tanks and assault guns were written off by 12 July.

Soviet formations, including the 3rd Tank Army and the 11th Guards Army, attacked the German 2nd Panzer Army, positioned in the rear of 9th Army. The outnumbered 2nd Panzer Army had trouble with the Soviet attack. Soviet formations made a deep penetration and threatened German supply routes. With their advance on Orel the encirclement of the 9th Army was possible.

The end of Zitadelle in the north

The 9th Army had to withdraw and used an opportunity created for them by the Luftwaffe. Their part in the offensive was over. Because the German armor was not concentrated and used with the same intensity as in the south, the German armor losses were comparatively light — 143 vehicles were total losses between 5 and 14 July. Central Front losses were 526 tanks. This failed to keep up with the steady influx of new soldiers and matériel arriving for the Red Army. Few Red Army guns were captured and those Red Army units that retreated did so on orders. The German attack failed to break through the main Soviet defence zones, and stalled. The Soviet counter-offensive compelled Model to withdraw or risk the destruction of both German Armies.

Northern analysis

A number of factors explain the 9th Army's lack of progress, mainly the combination of Soviet defensive planning and German lack of concentration of force. German armor was committed piecemeal rather than in strength and often without sufficient infantry support. Soviet defensive preparation was also a major factor. The Central Front under Marshal Rokossovsky had correctly anticipated the likely areas of German attack and had fortified

, which bore the brunt of the German attack, was far stronger in men and anti-tank guns than the other Central Front units and held the strongest defensive positions in the salient.

Model's army had fewer tanks than Manstein had in the south and the German 9th Army committed major units piecemeal because Model was afraid of the Bryansk Front, which stood ready for counterattack to the north of his army. Model decided to place his most powerful corps, Gruppe Esebeck (2 Pz. Div and 10 Pz. Gren. Div), far behind the frontline to use it as "fire brigade" against a possible onslaught by the Bryansk Front. Model's decision not to use his Panzer divisions as a concentrated force can be seen as the most significant reason for the poor penetration of the northern pincer. Finally, the 9th Army led with reinforced infantry divisions that were already in the line facing the Red Army, rather than attacking with uncommitted units.

Review of attack frontages and depth of German penetration clearly shows the success of the Red Army defensive tactics. While it began with a 45 km wide attack front on 5 July, the next day the German 9th Army's front was reduced to 40 km. This dropped to 15 km wide by 7 July and to only 2 km on 8–9 July. Each day, the depth of the German advance slowed: 5 km on the first day, 4 on the second, never more than 2 km each succeeding day. By 10 July the 9th Army had been stopped.

Much of the Soviet defensive success is attributable to its method of fire control, known to the Germans as Pakfront

. This relied upon a group of 10 or more anti-tank guns under a commander, which would fire at one target at a time. These positions were protected with heavy concentrations of mortar and machine gun nests, which were ordered to fire on German infantry only.

German attack

Von Manstein's troops in the south were better equipped than Model's in the north. The 4th Panzer Army and Army Group Kempf had 1,377 tanks and assault guns while the 9th Army possessed 988 tanks and assault guns. The 1,377 tanks included 102 Tiger I tanks and 200 Panthers.

.

At 04:00 the attack began; nearly all units advanced with good speed despite encountering well prepared defensive positions and minefields. Manstein's tanks were much more successful than their northern counterparts. The main reason for this was his better use of tanks in concentrated spearheads. In the south the Red Army had not been able to pinpoint the German attack sectors; this forced them to spread out their defenses evenly. Three of the four armies of the Voronezh Front had about 10 antitank guns per kilometre of front, whereas in the Central Front, guns were distributed twice as heavily in the active sectors. The Voronezh Front made the decision to hold the tactical zone thinly, leaving a higher proportion of units in deeper positions than in the Central Front. The Voronezh Front was weaker than the Central Front, and it faced much stronger German forces.

The new Panther tanks proved unreliable and failed to perform to expectations. When they moved to their assembly areas, 45 out of 200 new tanks experienced mechanical problems requiring repair. When the remaining Panthers launched their attack, they immediately ran into a minefield and many were immobilised.

In the first two days the 2nd SS Panzer Corps penetrated 25 km into the Russian lines and took Jakovlevo. The 200 Panthers of the 48th Tank Corps to their left spent more time in the workshops than fighting the enemy. Army Group Kempf, which was to assist the 2nd SS Panzer Corps, was outnumbered and had problems crossing the Donets River.

The steady progress of the German units forced the Russian leaders to commit some of their strategic reserves, as nearly all operational reserves were in action. The Steppe Front

 had been formed in the months leading up to the operation as a central reserve. As early as 6 July, Stavka decided to send the 2nd and 10th Tank Corps and the 5th Guards Tank Army to the southern sector; a day later, other formations got their marching orders. Vatutin planned an operational counterstrike against the German units but decided to cancel it after the failure of the northern counter-attack. Instead of seeking open battle against the German tanks, Vatutin let his tanks dig in, as Rokossovsky did in the north. Zhukov protested against this use of the tanks but Vatutin's decision stood.

German officers reported that they were slowed down by the "silent tanks" (Schweigepanzer), because it cost much time to overcome these camouflaged "bases". Despite the order to dig in many of their tanks, the Soviet units still had enough tanks to launch some counterattacks. On 7 July a German Tiger I

The Germans' advance was slowed. On the 9 July the first German units reached the Psel River

. The next day the first infantry units crossed the Psel. By 10 July German units in the south had lost 166 tanks. Despite the deep defensive system and minefields, German tank losses were remarkably low. The 11th of July was a successful day for German units; Army Group Kempf achieved a breakthrough and its 3rd Panzer Corps (6th, 7th and 19th Panzer Divisions) penetrated deep into Russian lines. The next night the 6th Panzer Division took a bridge over the Donets with a swift surprise attack. The 3rd Panzer Corps then advanced to Prokhorovka from the south and the 2nd SS Panzer Corps from the west, almost trapping the Russian 69th Army. At this moment Manstein thought the final breakthrough was achieved and now free of the minefields, could operate freely and destroy the Russian armored reserves in the open. The Russians, indeed, began moving their tank reserves toward the spearheads of Army Group South.

Prokhorovka

Accounts of this battle are controversial. The original Soviet account of a brave but reckless, although ultimately successful, massive Red Army assault on heavy German armor is now generally discounted; the most recent revisionist accounts suggest a Soviet debacle, with the Soviet charge on German armor being disrupted not by German tanks but because many T-34s fell into a Soviet anti-tank ditch.

What is generally not disputed is that the Red Army did enough, at great cost, to stop a German breakthrough. In that sense Prokhorovka remains a crucial turning point of the battle and indeed of the Great Patriotic War: here the German army was stopped.

On the morning of 12 July, Hoth, determined to push for a breakthrough, collected reserves of the 4th Panzer Army and advanced on Prokhorovka
Prokhorovka

. At the same time the 5th Guards Tank Army launched a series of attacks as part of multi-front counteroffensive in an attempt to catch the Germans off balance. The SS and Guards units collided west of Prokhorovka in country punctuated by farms, rolling hills and gullies.

In stifling heat, an eight-hour battle began. The German units had 494 tanks and self-propelled artillery pieces in the attack, 90% of them operational. The German force found itself heavily outnumbered by the 5th Guards Tank Army, who, moving mainly at night, had brought 593 tanks and 37 self-propelled artillery pieces into position at Stary Oskol. They had not yet been committed to battle, so they were fresh.

 and two other Soviet reserve corps.

The air battle was also intense. Von Manstein had intended it to be the decisive blow against the Red Army forces to prevent a breakthrough to Oboyan and Kursk. Sturmoviks from 291 ShAD attacked the 2nd SS Panzer Division throughout the day, causing significant damage to German armored formations. Simultaneously, waves of Hs 129s and Ju 87s inflicted losses on the 69th Army and 5th Guards Army. Although Soviet tank losses are unknown, a report from the 29th Tank Corps reported "heavy losses in tanks through enemy aircraft and artillery". Losses were so heavy that the advance had to be halted and a switch to the defensive ordered.

The Luftwaffe had complete air superiority over Prokhorovka, due to the VVS being concentrated over the flanks of the 4th Panzer Army.

The battle can best be described as a costly tactical loss but an operational draw for the Red Army. Neither the 5th Guards Tank Army nor the 2nd SS Panzer Corps accomplished their missions that day. After the battle was over, the Soviets held the area and were able to recover their disabled tanks and wounded crews.

Tank losses in the battle have been a contentious subject. Red Army losses have been given from 200 to 822 tanks, but the records show about 300 complete losses and as many damaged. German losses have been reported to be as low as 80 and as high as several hundred. The Soviets claim the Germans lost 400 tanks in this battle and 3,500 soldiers killed, but newer research suggest only about 500 lost men and much lower tank losses, with only a few tanks completely destroyed and about 40-80 damaged. In any event, the losses of both the 2nd SS Panzer Corps and the 5th Guards Tank Army in what has been called the greatest tank battle of all time were not of the epic proportions sometimes attributed to the Prokorovka engagement.

The end of Zitadelle in the south

While the German offensive had been stopped in the north by 10 July, in the south the overall situation still hung in the balance, even after 12 July. German forces on the southern wing, exhausted and heavily depleted, had breached the first two defensive belts and believed that they were about to break through the last belt. In fact at least five more defensive zones awaited them, although they were not as strong as the initial belts, and some of them did not have troops deployed. Red Army defenders had been weakened, and major parts of their reserve forces had been committed. Still, the available uncommitted Red Army reserves were far larger than the few available German reserves.

On 16 July, German forces withdrew to their start line. Severely depleted, the Germans then had to face Operation Polkovodets Rumyantsev
Operation Polkovodets Rumyantsev
Operation Polkovodets Rumyantsev was a code name for the Belgorod-Kharkov Strategic Offensive Operation conducted by the Red Army between 3 August 1943 and 23 August 1943 against the Wehrmacht's 4th Panzer Army and Army Group Kempf during World War II. The operation was conducted by the Voronezh...

, an offensive launched to smash the German forces in the Belgorod–Kharkov area on 3 August. Belgorod fell on 5 August, and on 23 August, Kharkov fell, despite fierce resistance from German forces. With the capture of Kharkov, the Soviets considered the Battle of Kursk over.

Southern analysis

The German forces made steady progress, but, as in the north, attack frontage width and penetration depth tended to drop as the attack proceeded. The trend was not as marked as in the north, however. A 30 km wide attack frontage on 5 July became 20 km wide by 7 July and 15 km by 9 July. Likewise, the depth of penetration dropped from 9 km on 5 July to 5 km on 8 July and 2–3 km each day thereafter until the attack was cancelled.

Red Army minefields and artillery were successful in delaying the German attack and inflicting losses. The ability of dug-in Red Army units to delay the Germans allowed their own reserves to be brought up into threatened sectors. Over 90,000 additional mines were laid during the operations by small mobile groups of engineers, generally working at night immediately in front of the expected German attack areas. There were no large-scale captures of prisoners nor any great loss of artillery, indicating that Soviet units were giving ground in good order.

German losses can be seen in the example of the Großdeutschland Division

, which began the operation with 118 tanks. On 10 July, after five days of fighting, the division reported it had 3 Tigers, 6 Panthers, and 11 Pzkw-III and Pzkw-IV tanks operational. XLVIII Panzer Corps reported, overall, 38 Panthers operational with 131 awaiting repair, out of the 200 it started with on 5 July.

 and declared his intention to "temporarily" call off Operation Zitadelle. Von Manstein attempted to dissuade him, arguing that Zitadelle was on the brink of victory: "on no account should we let go of the enemy until the mobile reserves which he had committed were decisively beaten". In an unusual reversal of their roles, Hitler gave von Manstein a few more days to continue the offensive, but on 17 July, he ordered a withdrawal and canceled the operation. He then ordered the entire SS Panzer Corps to be transferred to Italy.

Hitler's decision to call off the operation at the height of the tactical battle has since been strongly criticized by German generals in their memoirs, and by some historians. For example, it has been pointed out that the SS Panzer Corps would have taken three months to be transferred to Sicily, and thus could not possibly have affected the outcome there, while its contribution to the Kursk operation was vital.

Only one German division, the 1st SS Panzer Division Leibstandarte Adolf Hitler, departed for Italy, without their equipment. The remainder stayed to face the Red Army counteroffensive launched in the wake of the failed German offensive.

Reasons for the failure of Zitadelle

Historian Karl-Heinz Frieser points out these reasons for the failure of Operation Zitadelle:
  • The Soviets had numerical superiority. Frieser points out that the biggest problem of the OKW was the shortage of infantry. The OKH had no operational reserve while the Red Army could field an entire front

    ) as reserve. That the Red Army had more tanks than the Wehrmacht had less influence on the outcome according to Frieser.

  • Repeated delays by Hitler gave the Red Army enough time to fortify the bulge around Kursk to an enormous fortress. High officers like Manstein and Zeitzler pushed for a fast attack to catch the Red Army unprepared and low on morale after the third battle of Kharkov. The overlap with the Allied invasion of Sicily

 draws these conclusions:
  • The German defeat at Kursk did not come about by the "often-exaggerated numerical superiority" of the Soviet armed forces. The principal factor at Kursk was the revolution in Soviet command, staff, operational and tactical techniques. The General Staff had learned lessons from previous battles and disseminated "war experience" based on "exhaustive" analysis of battles, operations and campaigns. These lessons were added to Soviet doctrine (Soviet deep battle), producing new procedures. Glantz and House have asserted the tank strength was even, between 1:1 and 1.5:1 in the Soviets' favour.

  • The Soviets introduced new operational and tactical techniques, and had solved many of the problems of integrating arms and services into "a true combined arms

     operation". He emphasises "sophisticated understanding of intelligence, deception, and anti-tank defence". Similar improvements were made in the combined use of artillery, tanks, engineers, and infantry to break German defences on a narrow front. At Prokhorovka and in the Kutuzov operations, the Red Army gained experience with mobile armored formations and mechanized corps that became the hallmark of Soviet deep operations. These formations demonstrated their ability to match the best efforts of the German Panzer force. Operations still needed to be perfected to reduce huge casualties. Nevertheless, the German command recognised that at Kursk they faced an entirely new and more competent Red Army.

  • Defensive tactics had improved. Skillful use of anti-tank artillery in strong points and the use of separate tank brigades, tank regiments and self-propelled gun units to support them offered mobile defence support. These units participated in wearing down tactical attacks against enemy spearheads. The transitional year of 1943 was decisive for the Soviet war effort. Operational and tactical techniques tested and smoothed out in 1943 would be refined further and perfected in 1944 and 1945. "The elementary education the Red Army received in 1941–42 gave way to the secondary education of 1943. In 1944 and 1945 the Soviets would accomplish university-level and graduate study in the conduct of war".

     level), the Red Army was not particularly impressive and received significantly poorer training. Zaloga points out that there were still many tactical lessons to be learned; however by 1943 the gap between Soviet and German tanker training had "narrowed greatly", and the Soviets were soon at a comparable level with the Germans.

  • The Soviets, in terms of operational art, were adept at using mobile tank formations. Zaloga asserts that Soviet operational methods were superior, allowing Soviet field commanders to bluff, baffle and overwhelm their opponents.

 makes the following interpretations:
  • The quality of the two air forces were even. The Soviets had introduced air-to-ground communications, radar, a proper maintenance system, and depots for forward fuel reserves. This allowed aircraft to fly twenty missions in the heat of the battle (while the Luftwaffe suffered shortages).

  • The Soviet tanks were not inferior in quality. Although the T-34 model (with its 76 mm main gun) was out-ranged by German Tiger I

    . To counter the Tiger tank, the Soviets used their tanks in a "hand-to-hand" combat role. Crews were ordered to close the range so that it would not become an issue. According to Glantz and House the Soviet tanks pressed home their initial attacks despite significant German advantages: the range of the German tanks' 88mm gun, German air superiority, and attacking a well dug-in enemy while covering flat rolling terrain. Even so, the loss ratio was less than 2:1, 320 German and 400 Soviet AFVs.

) attacked the largely undefended German north flank of the 2nd Panzer Army on 12 July. The 2nd Panzer Army was diminished as many tanks were transferred to other armies before Zitadelle. On 12 July the attacking forces numbered 487,111 combat troops supported by 1,401 tanks and 15,109 guns. Three days later the second phase of Operation Kutuzov started with the attack of the German 9th Army by several Russian armies. The combined troops deployed for Kutuzov now numbered 1,286,049 men supported by 2,409 tanks and 26,379 guns.

The operations of the Bryansk Front marked the beginning of the Russian summer offensive. The artillery barrage was heavy and the first German lines were overrun. German defensive lines were deeper than expected and many Russian spearheads were slowed and sustained heavy casualties, but in some areas the Russian units achieved deep penetrations. The Germans lacked reserves to block these penetrations, so the situation became very dangerous for the 2nd Panzer Army. On 13 July Army Group Centre gave command of the 2nd Panzer Army to Model, who already commanded the German 9th Army. Model now was in control of all German units in the Orel area.

The situation for the Germans worsened as Russian breakthroughs threatened the entire 9th Army. Model sent nearly all of his Panzer units to aid the 2nd Panzer Army whose northern front was about to collapse, while the 4th Army in the north sent the 253rd Infantry Division. German units achieved a temporary stabilization of the front but meanwhile the 9th Army started to withdraw from the captured ground. Initially, the Russian Central Front followed hesitantly, but then started attacking in earnest with heavy air support. On 18 July the 9th Army was at the same position as on 5 July, before the start of Zitadelle.

Russian tank formations failed to achieve an operational breakthrough despite their numerical superiority. Red Army tank armies repeated their attacks against the same positions with the same methods and suffered heavy casualties in men and tanks. For example, the 4th Tank Army lost 84% of their T-34s and 46% of their light tanks within a few days. After two weeks of fighting the 3rd Guards Tank Army had lost half of their 800 tanks. The German armies conducted a fighting withdrawal to Hagen-Stellung.

Organized by the Red Army, approximately 100,000 partisans supported the Russian operations. German movements were hampered by partisans disrupting German supply routes, especially railway lines. On 3 August partisans launched a large operation against the German rear, the so called "Railway-war".

By shortening their line the Wehrmacht freed 19 divisions, which could be used elsewhere or held as reserves. Nevertheless, the Soviets achieved a complete breakthrough. The Soviets massed a concentration of artillery and tanks on small narrow fronts and used sophisticated artillery techniques to defeat German fortified positions despite tenacious German defences. Operation Kutuzov "was a perfect example of the newly sophisticated Soviet way of war". On 5 August the 3rd Guards Tank Army entered Orel and by 18 August, the Bryansk Front had reached the city Bryansk, "completely eliminating the German salient in the region".

The battle was the bloodiest of the three major operations during the Battle of Kursk. The German overall losses were 86,064 men; the Red Army lost 112,529 men and 317,361 were wounded. The losses for the Red Army were particularly high for tanks and assault guns: 2,586 of them were written off during Kutuzov. German tank losses are not available for this battle, but Heeresgruppe Mitte (Army Group Center) lost 343 during both Zitadelle and Kutuzov.

Some of the Soviet commanders were displeased, complaining that an even greater victory might have been won. Marshal Rokossovsky said, "Instead of encircling the enemy, we only pushed them out of the bulge... The operation would have been different if we had used our force for two heavy punches which met at Bryansk". Zhukov held a similar opinion. Stalin instead thought encirclement tactics could wait: "It is our task to push them from our territory. We can trap them when they are weaker".

planned Operation Rumyantsev as the major thrust of their summer offensive. The aim was to destroy Manstein's 4th Panzer Army and Army Group Kempf and later the southern wing of Heeresgruppe Süd (Army Group South). The German 1st Tank Army and newly formed 6th Army were to be trapped by an advance to the Black Sea. The Russian Southern Front and the Southwestern Front attacked as early as 17 July.

The Voronezh Front and the Steppe Front deployed about 1,144,000 men supported by 2,418 tanks and 13,633 guns and rocket launchers for the attack. At the start of "Rumyantsev" the Germans fielded only 237 tanks and assault guns. Manstein believed that the Soviets were incapable of launching an offensive in the southern sector, and dispatched his reserves (II SS Panzer Corps, XXIV Corps and XXXXVIII Panzer Corps) southward to deal with Soviet offensives aimed at the Dnieper and Mius Rivers. The Soviet operations in those regions were actually carefully planned diversion operations. The Soviet plan worked; German reserves were removed from the critical Kharkov axis (conforming to Maskirovka: military deception). The tactical operations across the Mius were unsuccessful, but achieved their primary aim of diverting German forces further away from Kharkov, although by Soviet accounts, the Stavka had wished for more.

For the Kharkov offensive the Red Army focused enormous firepower on a 30 km front. The 5th and 6th Guards Armies, two elements that had borne the brunt of the German offensive, and the Soviet 53rd Army took part. The artillery concentration was necessary to puncture the first five German defence lines between Kursk and Kharkov. The 1st Tank Army and 5th Guards Army, supported by two additional mobile corps, would act as a mobile operational unit to encircle Kharkov from the north and west. To the west, four separate tank corps would support the 27th and 40th Armies would make supporting attacks. To the east and south-east, the 69th and 7th Guards Armies, followed by the 57th Army of the Southwestern Front, would also support the attack.

On 3 August the initial attack demonstrated the growing sophistication of Soviet tactical art. Heavy and long-range artillery bombarded German positions, supported by anti-tank shock groups, ready to repel counter attacks. The German defence was tenacious, and two tank armies had to enter the battle to secure a penetration. By 5 August the Soviets had broken deep into the German rear and captured Belgorod

, advancing some 60 km into German lines. Each combined-arms army pressed the German defences from the north and east.

German reserves were rushed from the Orel sector and north from the Donbas regions (where Soviet maskirovka operations had diverted them) and tried to break up Soviet attacks. The only success was achieved by the Grossdeutschland Panzergrenadier Division, which succeeded in delaying the 40th Army from 6–7 August. Four infantry divisions and seven Panzer and motorised divisions were assembled under the III Panzer Corps. Manstein tried to repeat the success of the Third Battle of Kharkov

, where the Soviets had been over-extended and defeated. This time the Soviets were alert to the danger, and it was the German forces that were worn down. On 12 August, units of the newly arrived 2nd SS Panzergrenadier Division Das Reich and 3rd SS Panzergrenadier Division Totenkopf started a counterattack against two Soviet Armies near Bogodukhov, 30 km northwest of Kharkov. The Waffen-SS units trapped and annihilated many Soviet units during the following maneuver battles. To assist the 6th Guards Army and the 1st Tank Army, the 5th Guards Tank Army joined the battles. All three Soviet armies suffered heavily and the tank armies lost more than 800 of their initial 1,112 tanks. After the counterattack of the two German divisions, the Soviet tank armies were no longer capable of offensive actions. The Soviet advance around Bogodukhov was stopped so the German units now tried to close the gap between Achtryrka and Krasnokutsk. The counterattack started on 18 August and on 20 August Totenkopf and Großdeutschland met behind the Soviet units. Parts of two Soviet armies and two tank corps were trapped, but the trapped units heavily outnumbered the German units. Many Soviet units were able to break out while suffering heavy casualties. After this setback the Soviet troops focused on Kharkov and captured it after heavy fighting on 23 August. The battle is usually referred to as the Fourth Battle of Kharkov by the Germans and the Belgorod–Kharkov offensive operation by the Soviets.

Soviet casualties in the Belgorod–Kharkov sector during this operation were 71,611 killed and 183,955 wounded; 1,864 tanks and 423 artillery guns were lost.

German losses were 10,000 killed and 20,000 wounded. German tank losses are estimated at least 8 times lower than Soviet tank losses of 1,864.

Results

The campaign was a decisive Soviet success. For the first time, a major German offensive had been stopped before achieving a breakthrough. The Germans, despite using more technologically advanced armor than in previous years, were unable to break through the in-depth defenses of the Red Army, and were surprised by the significant operational reserves of the Red Army. This was an outcome that few had predicted, and it changed the pattern of operations on the Eastern Front. The victory had not been cheap; the Red Army

, diverting some of Germany's resources and attention. Both sides had their losses, but only the Soviets had the manpower and the industrial production to recover fully. The Germans never regained the initiative after Kursk and never again launched a major offensive in the East.

The loss convinced Hitler of the incompetence of his General Staff. His interference in military matters progressively increased, so that by the end of the war he was involved in tactical decisions. The German Army went from loss to loss as Hitler attempted personally to micromanage the day-to-day operations of what soon became a three-front war. The opposite was true for Stalin. After seeing Stavka's planning justified on the battlefield, he trusted his advisors more, and stepped back from operational planning, only rarely overruling military decisions. The Red Army gained more freedom and became more and more fluid as the war continued.
