Greece

Greece, at the time a state of 2,666,000 people, was considered the weakest of the three main allies, since it fielded the smallest army and had suffered an easy defeat against the Ottomans 16 years before in the Greco-Turkish War of 1897. A British consular dispatch from 1910 illustrates the common perception of the Greek Army's capabilities at the time: "if there is war we shall probably see that the only thing Greek officers can do besides talking is to run away". However Greece was the only Balkan country to possess a substantial navy. This was vital to the League, as it could prevent Ottoman reinforcements from being rapidly transferred by ship from Asia to Europe. This fact was readily appreciated by the Serbs and Bulgarians, and was the chief factor in initiating the process of Greece's inclusion in their alliance. As the Greek ambassador to Sofia put it during the subsequent negotiations that led to Greece's entry in the League: "Greece can provide 600,000 men for the war effort. 200,000 men in the field, and the fleet will be able to stop 400,000 men being landed by Turkey between Salonica and Gallipoli

, called in 1911, when the war began. Under its supervision, the Greeks had adopted the triangular infantry division as their main formation, but more importantly, the overhaul of the mobilization system allowed the country to field and equip a far greater number of troops than it had in 1897: while foreign observers estimated a mobilized force of approximately 50,000 men, the Greek Army fielded 125,000, with another 140,000 in the National Guard and reserves. Upon mobilization, as in 1897, this force was grouped in two field armies, reflecting the geographic division between the two operational theaters open to the Greeks: Thessaly

The Greek Navy was relatively modern, strengthened by the recent purchase of numerous new units and undergoing reforms under the supervision of a British mission. Invited by Prime Minister Venizelos in 1910, the mission began its work upon its arrival in May 1911. Granted extraordinary powers and under the energetic leadership of Vice Admiral Lionel Grand Tufnell, it thoroughly reorganized the Navy Ministry and dramatically improved the number and quality of exercises in gunnery and fleet maneuvers.

. There were also eight destroyers built in 1906–1907, and six new destroyers that were hastily bought in summer 1912 as the imminence of war became apparent.

However, at the outbreak of the war, the Greek fleet was still far from ready. The Ottoman battlefleet retained a clear advantage in number of ships, speed of the main surface units and, more importantly, in the number and caliber of the ship's guns. In addition, as the war caught the fleet in the middle of its expansion and reorganization, fully a third of the fleet (the six new destroyers and the submarine Delfin

) only reached Greece after hostilities had started, necessitating a reshuffling of crews and leading to a lack of necessary familiarization and training time. Coal stockpiles and other war stores were in short supply, while the Averof herself had arrived with barely any ammunition, and would remain so until late November.

Ottoman Empire

In 1912, the Ottomans found themselves in a difficult position. They had a large population, 26 million, but only just over 6.1 million of them lived in the European part of the Empire, and of these only 2.3 million were Muslims, the rest being Christians, considered unfit for conscription. The very poor transport network, especially in the Asian part, dictated that the only reliable way for a mass transfer of troops to the European theater was by sea, but that was under question due to the presence of the Greek fleet in the Aegean Sea. They were also still engaging in a protracted war with the Italians

). This resulted in different groups competing for influence within the military. An effort had been made to reorganize the army by a German mission, but its effects had not taken hold, and the Ottoman army was caught in the midst of reform and reorganization. In addition, several of the army's best battalions had been transferred to Yemen

 to face the ongoing rebellion there, and in the summer of 1912, the Ottoman High Command took the disastrous decision to dismiss some 70,000 mobilized troops. The regular army (Nizam) was composed of well-equipped and trained active divisions, but the reserve units (Redif) that reinforced it were ill-equipped, especially in artillery, and badly trained.

The Ottomans' strategic situation was difficult, as their borders were almost impossible to defend against a co-ordinated attack by the Balkan states. Nevertheless, the Ottoman leadership decided to defend the entirety of their territory. As a result, the available forces—which could not be easily reinforced from Asia due to Greek control of the sea and the inadequacy of the Ottoman railway system—were dispersed too thinly across the region and failed to stand up to the rapidly mobilized Balkan armies. The Ottomans had three armies in Europe (the Macedonian, Vardar and Thracian Armies) with 1,203 pieces of mobile and 1,115 fixed artillery on fortified areas. The Ottoman High Command repeated the error of previous wars in neglecting the established command structure and creating new superior commands, the Eastern Army

According to the organizational plan the men of the Western Group had to number 598,000. But slow mobilization procedures and the poor railroad efficiency reduced drastically the available men, so that when war began, according to the Western Army Staff there were only 200,000 men available. Although during the next period more men reached the units, due to the war casualties, the Western Group never came near its nominal strength. In time of war the Ottomans planned to bring more troops in from Syria, both Nizamiye and Redif. Greek naval supremacy however prevented those reinforcements from arriving. Instead those soldiers had to deploy via the land route, and most never made it to the Balkans.

The Ottoman General Staff, assisted by the German Military Mission, developed 12 war plans, designed to counter various combinations of opponents. Work on plan No. 5, which was against a combination of Bulgaria, Greece, Serbia and Montenegro, was very advanced, and had been sent to the Army staffs for them to develop local plans.

State of the Ottoman Navy

The Ottoman fleet had performed abysmally in the Greco-Turkish War of 1897, forcing the Ottoman government to begin a drastic overhaul. Older ships were retired and newer ones acquired, chiefly from France and Germany. In addition, in 1907 the Ottomans called in a British naval mission to update their training and doctrine. The mission, headed by Admiral Sir Douglas Gamble, would find its task almost impossible however. To a large extent this was due to the political upheaval in the aftermath of the Young Turk Revolution

, further obstructed drastic reform. In addition, British attempts to control the Navy's construction programme were met with suspicion by the Ottoman ministers, and funds for Gamble's ambitious plans for new ships were not available.

To counter the Greek acquisition of the Averof, the Ottomans tried to buy the new German armoured cruiser or even the battlecruiser

, these two ships formed the core of the Ottoman fleet. By the summer of 1912 however, they were already in a poor state due to chronic neglect: the rangefinders and ammunition hoists had been removed, the telephones were not working, the pumps were corroded, and most of the watertight doors could no longer be closed.

Operations

Montenegro started the First Balkan War by declaring war against the Ottomans on .

Bulgarian theater of operations

The western region of the Balkans, including Albania, Kosovo, and Macedonia was less important to the resolution of the war and the survival of the Ottoman Empire than the Thracian theater, where the Bulgarians fought major battles against the Ottoman forces. But although the geography dictated that Thrace would be the major battlefield in a war with the Ottoman Empire, the position of the Ottoman Army there was jeopardized by erroneous intelligence estimates of their opponents' order of battle. Unaware of the secret prewar political and military settlement over Macedonia between Bulgaria and Serbia, the Ottoman leadership assigned the bulk of their forces there.

, one of the most influential people in the Ottoman capital, had reported to Berlin on October 21 that the Ottoman forces believed that the bulk of the Bulgarian army would be deployed in Macedonia with the Serbs. Subsequently the Ottoman HQ under Abdullah Pasha expected to meet only three Bulgarian infantry divisions, accompanied by cavalry, east of Adrianople. According to E. J. Erickson this assumption possibly resulted from their analysis of the objectives of the Balkan Pact - but it had deadly consequences for the Ottoman Army in Thrace, which would have to defend the area against the bulk of the Bulgarian army against impossible odds. This misappraisal was also the reason of the catastrophic aggressive Ottoman strategy at the start of the campaign in Thrace.

Bulgarian offensive and advance to Çatalca

In the Thracian front the Bulgarian army had placed 346,182 men against the Ottoman 1st Army with 105,000 men in eastern Thrace and the Kircaali detachment of 24,000 men in western Thrace. The Bulgarian forces were divided into the 1st (Lt. Gen. Vasil Kutinchev

The first large-scale battle occurred against the Adrianople-Kirk Kilisse defensive line, where the Bulgarian 1st and 3rd Armies (together 174,254 men) defeated the Ottoman East Army (of 96,273 combatants), near Gechkenli, Seliolu and Petra. The Ottoman XV Corps urgently left the area to defend the Gallipoli peninsula against an expected Greek amphibious assault, which in the event never materialized. The absence of this Corps created an immediate vacuum between Adrianople and Demotika, and the 11th Infantry Division from the Eastern Army's IV Corps was moved there to replace it. Thus one complete army corps was removed from the Eastern Army's order of battle. As a consequence of the insufficient intelligence on the invading forces, the Ottoman offensive plan failed completely in the face of Bulgarian superiority forcing Abdullah Pasha

. Thus the Greek Navy played a crucial albeit indirect role in the Thracian campaign, by neutralizing three corps, a significant portion of the Ottoman Army, in the all-important opening round of the war. Another, more direct role, was the emergency transportation of the Bulgarian 7th Rila Division from the Macedonian to the Thracian front after the termination of the operations there.

After the battle of Kirk Kilisse the Bulgarian high command decided to wait a few days, a decision which allowed the Ottoman forces to occupy a new defensive position on the Luleburgaz

. Nevertheless, it resulted in unexpected success. In the north the Bulgarians were forced to withdraw about 15 km and to the south over 20 km to their secondary defensive positions. With the end of the attack in Gallipoli the Ottomans cancelled the operation, reluctant to leave the Çatalca Line, but several days passed before the Bulgarians realized that the offensive was over. By February 15 the front had again stabilized but the fighting along the static lines continued until the armistice. The battle, which resulted in heavy Bulgarian casualties, could be characterized as an Ottoman victory at the tactical level, but strategically it was a failure, since it did nothing to prevent the failure of the Gallipoli-Şarköy operation or relieve the pressure on Adrianople.

Fall of Adrianople and Serbo-Bulgarian friction

The failure of the Şarköy-Bulair operation and the deployment of the 2nd Serbian Army together with its much needed heavy siege artillery sealed Adrianople's fate. On 11 March after a two weeks bombardment that destroyed much of the fortified structures around the city, the final assault started with Allied forces enjoying a crushing superiority over the Ottoman garrison. Under the command of General Nikola Ivanov

, the Bulgarian 2nd Army with 106,425 men and two Serb divisions with 47,275 men eventually conquered the city, but at a high price: the Bulgarians suffering 8,093 and the Serbs 1,462 casualties. The Ottoman casualties for the entire Adrianople campaign reached 13,000 killed. The number of prisoners is less clear. The Ottoman Empire began the war with 61,250 men in the Adrianople fortress. Richard Hall notes that 60,000 men were captured. Adding to the 13,000 killed, the modern Turkish General Staff History notes that 28,500 man survived captivity leaving only 20,000 men unaccounted as possibly captured (including the unspecified number of wounded). Bulgarian losses for the entire Adrianople campaign amounted to 18,282. According to both R.C. Hall and E.J. Erickson, the assault was an unnecessary bloodshed, it was more of a political decision and took place only to inflate the national pride of Tsar Ferdinand and some Bulgarian politicians, since the fortress would have to surrender anyhow by the end of the month due to starvation. The most important result however was that now the Ottoman command lost all hopes of regaining the initiative, which made any further fighting pointless.

The battle had major and key results in the Serbo-Bulgarian relations putting the seeds of the countries' confrontation some months later. The Bulgarian censor rigorously cut any references about the Serbian participation in the operation in the telegrams of the foreign correspondents. The public opinion in Sofia thus failed to realise the crucial services Serbia rendered in the battle. Accordingly the Serbs claimed that their troops of the 20th Regiment were those who captured the Ottoman commander of the city, and that Colonel Gavrilović was the allied officer who accepted Shukri's official surrender of the garrison, a statement that Bulgarians disputed. Subsequently the Serbs officially protested, pointing out that although they had sent their troops to Adrianople to win for Bulgaria territory the acquisition of which had never been foreseen by their mutual treaty, the Bulgarians had never fulfilled the clause of the treaty requiring Bulgaria to send 100,000 men to help the Serbians in their Vardar front. The Bulgarians answered that their staff had informed the Serbs about that on 23 August. The friction escalated some weeks later when the Bulgarian delegates in London bluntly warned the Serbs that they must not expect Bulgarian support on their Adriatic claims. The Serbs angrily replied that that was a clear withdrawal from the prewar agreement of mutual understanding according to the Kriva Palanka-Adriatic line of expansion, but the Bulgarians insisted that in their view, the Vardar Macedonian part of the agreement remained active and that the Serbs were still obliged to surrender the area as agreed. The Serbs answered by accusing the Bulgarians of maximalism, pointing out that if they lost both northern Albania and Vardar Macedonia, their participation in the common war would had been virtually for nothing. The tension soon was expressed in a series of hostile incidents between the two armies along their common line of occupation across the Vardar valley. The developments essentially ended the Serbo-Bulgarian alliance and made a future war between the two countries inevitable.

Macedonian front

Ottoman intelligence had also disastrously misread Greek military intentions. In retrospect, it would appear that the Ottoman staffs believed that the Greek attack would be shared equally between the two major avenues of approach, Macedonia and Epirus. The 2nd Army staff had therefore evenly balanced the combat strength of the seven Ottoman divisions between the Yanya Corps and VIII Corps, in Epirus and southern Macedonia respectively. The Greek Army also fielded seven divisions, but, having the initiative, concentrated all seven against VIII Corps, leaving only a number of independent battalions of scarcely divisional strength in the Epirus front. This had fatal consequences for the Western Group of Armies, since it led to the early loss of the strategic center of all three Macedonian fronts, the city of Thessaloniki

, a fact that sealed their fate. In an unexpectedly brilliant and rapid campaign, the Army of Thessaly seized the city. In the absence of secure sea lines of communications, the retention of the Thessaloniki-Constantinople corridor was essential to the overall strategic posture of the Ottoman Empire in the Balkans. Once this was gone, the defeat of the Ottoman Army became inevitable. To be sure, the Bulgarians and the Serbs played an important role in the defeat of the main Ottoman armies. Their great victories at Kirkkilise, Luleburgaz, Kumanovo, and Monastir shattered the Eastern and Vardar Armies. However, these victories were not decisive in the sense that they ended the war. The Ottoman field armies survived, and in Thrace, they actually grew stronger day by day. In the strategic point of view these victories were enabled partially by the weakened condition of the Ottoman armies brought about by the active presence of the Greek army and fleet.

 surrendered Thessaloniki and its garrison of 26,000 men to the Greeks on . Two Corps HQs (Ustruma and VIII), two Nizamiye divisions (14th and 22nd) and four Redif divisions (Salonika, Drama, Naslic and Serez) were thus lost to the Ottoman order of battle. Additionally, the Ottoman forces lost 70 artillery pieces, 30 machine guns and 70,000 rifles (Thessaloniki was the central arms depot for the Western Armies). The Ottoman forces estimated that 15,000 officers and men had been killed during the campaign in south Macedonia, bringing total losses up to 41,000 soldiers. Another direct consequence was that the destruction of the Macedonian Army sealed the fate of the Ottoman Vardar Army, which was fighting the Serbs to the north. The fall of Thessaloniki left it strategically isolated, without logistical supply and depth to maneuver, ensuring its destruction.

Upon learning of the outcome of the battle of Yenidje, the Bulgarian high command urgently dispatched their 7th Rila Division from the north in the direction of the city. The division arrived there a week later, the day after its surrender to the Greeks. Until November 10, the Greek-occupied zone had been expanded to the line from Lake Dojran to the Pangaion hills

 weight, the Greek planners expected it to sortie from the straits early in the war. Given the Greek fleet's unpreparedness resulting from the premature outbreak of the war, such an early Ottoman attack might well have been able to achieve a crucial victory. Instead, the Ottoman Navy spent the first two months of the war in operations against the Bulgarians in the Black Sea, giving the Greeks valuable time to complete their preparations and allowing them to consolidate their control of the Aegean.

 the straits, but was not taken up for fear of international reactions. On 7 December, the head of the Ottoman fleet Tahir Bey was replaced by Ramiz Naman Bey, the leader of the hawkish faction among the officer corps. A new strategy was agreed, whereby the Ottomans were to take advantage of any absence of Averof to attack the other Greek ships. The Ottoman staff formulated a plan to lure a number of the Greek destroyers on patrol into a trap. A first such effort on 12 December failed due to boiler trouble, but the second try two days later resulted in an indecisive engagement between the Greek destroyers and the cruiser Mecidiye.

The war's first major fleet action, the Naval Battle of Elli

, was fought two days later, on . The Ottoman fleet, with four battleships, nine destroyers and six torpedo boats, sailed to the entrance of the straits. The lighter Ottoman vessels remained behind, but the battleship squadron moved on north under cover of the forts at Kumkale and engaged the Greek fleet, coming from Imbros, at 9:40. Leaving the older battleships behind, Kountouriotis led the Averof into independent action: utilizing its superior speed, it cut across the Ottoman fleet's bow. Under fire from two sides, the Ottomans were quickly forced to withdraw to the Dardanelles. The whole engagement lasted less than an hour, in which the Ottoman suffered heavy damage to the Barbaros Hayreddin and 18 dead and 41 wounded (most during their disorderly retreat) and the Greeks one dead and seven wounded.

In the aftermath of Elli, on 20 December the energetic Lt. Commander Rauf Bey was placed in effective command of the Ottoman fleet. Two days later he led his forces out, hoping again to trap the patrolling Greek destroyers between two divisions of the Ottoman fleet, one heading for Imbros and the other waiting at the entrance of the straits. The plan failed as the Greek ships quickly broke contact, while at the same time the Mecidiye came under attack by the Greek submarine Delfin, which launched a torpedo against it but missed; the first such attack in history. During this time, the Ottoman Army continued to press upon a reluctant Navy a plan for the re-occupation of Tenedos, which the Greek destroyers used as a base, by an amphibious operation. The operation was scheduled for 4 January. On that day, weather conditions were ideal and the fleet was ready, but the Yenihan regiment earmarked for the operation failed to arrive on time. The naval staff nevertheless ordered the fleet to sortie, and an engagement developed with the Greek fleet, without any significant results on either side. Similar sorties followed on 10 and 11 January, but the results of these "cat and mouse" operations were always the same: "the Greek destroyers always managed to remain outside the Ottoman warships' range, and each time the cruisers fired a few rounds before breaking off the chase."
In preparation for the next attempt to break the Greek blockade, the Ottoman Admiralty decided to create a diversion by sending the light cruiser Hamidiye

It was hoped that the Averof, the only major Greek unit fast enough to catch the Hamidiye, would be drawn in pursuit and leave the remainder of the Greek fleet weakened.

Serb-Montenegrin theater of operations

The Serbian forces operated against major part of Ottoman Western army which were located in the areas of Novi Pazar, Kosovo and northern and eastern Macedonia. Strategically the Serbian forces were divided into four independent armies and groups: Javor brigade and Ibar Army against Ottoman forces in the area of Novi Pazar, Third Army against Ottoman forces in the areas of Kosovo and Metohija, First Army against Ottoman forces in the area of northern Macedonia and Second Army (operating from the Bulgarian territory) against Ottoman forces in the area of eastern Macedonia. The decisive battle was expected to be fought in the area of northern Macedonia, more specifically in the plains of Ovče Pole
Ovce Pole

, where the main forces of Ottoman Vardar Army were expected to concentrate. According to the plan of the Serbian Supreme Command, three Serbian armies (First, Second and Third) were supposed to encircle and destroy the Vardar Army in that area, with First Army advancing from the north (direction Vranje-Kumanovo-Ovče Pole ), Second Army advancing from the east (direction Kriva Palanka-Kratovo-Ovče Pole) and Third Army advancing from the north-west (direction Priština-Skopje-Ovče Pole). In the execution of this plan the main role was given to the First Army while Second Army was expected to cut of the Vardar Army's retreat route, and if necessary attack its rear and right flank. The main goal of Third Army was to liberate Kosovo and Metohija and if necessary give assistance to the First Army by attacking the Vardar Army's left flank and rear. Ibar Army and the Javor brigade had a minor role in the Serbian plan, they were expected to conquer and secure areas of the Sandjak of Novi Pazar and replace Third Army in Kosovo after it advanced further south.

The last battle for Macedonia was the battle of Monastir, in which the remains of the Ottoman Vardar Army were forced to retreat to central Albania. After the battle, Prime Minister Pasic asked Gen. Putnik to take part in the race for Thessaloniki. Putnik declined and instead turned his army to the west, towards Albania, foreseeing that a future confrontation between the Greeks and Bulgarians over Thessaloniki could greatly help Serbia's own plans over Vardar Macedonia.

As a result, any possible preventative effect of the common official warning was cancelled by the mixed unofficial signals, and failed to prevent or to stop the war:

At the same time, the Habsburg empire had its own internal problems with the significant Slav populations that campaigned against the German-Hungarian control of the multinational state. Serbia, whose aspirations in the direction of the Austrian-held Bosnia were no secret, was considered an enemy and the main tool of Russian machinations that were behind the agitation of Austria's Slav subjects. But failed to achieve German backup for firm reaction. Initially, Emperor Wilhelm II told the Archduke Franz Ferdinand
