Meanwhile other divisions of the Serbian army had joined hands with the Montenegrins, and occupied almost without opposition the long-coveted _sandjak_ of Novi-Pazar (the ancient Serb Raška), to the inexpressible rage of Austria-Hungary, which had evacuated it in 1908 in favour of its rightful owner, Turkey. At the same time a Serbian expeditionary corps marched right through Albania, braving great hardships on the way, and on November 30 occupied Durazzo, thus securing at last a foothold on the Adriatic. Besides all this, Serbia, in fulfilment of its treaty obligations, dispatched 50,000 splendidly equipped men, together with a quantity of heavy siege artillery, to help the Bulgarians at the siege of Adrianople. On December 3 an armistice was signed between the belligerents, with the condition that the three besieged Turkish fortresses of Adrianople, Scutari, and Yanina must not be re-victualled, and on December 16, 1912, peace negotiations were opened between representatives of the belligerent countries in London. Meanwhile the Germanic powers, dismayed by the unexpected victories of the Balkan armies and humiliated by the crushing defeats in the field of the German-trained Turkish army, had since the beginning of November been doing everything in their power to support their client Turkey and prevent its final extinction and at the same time the blighting of their ambitions eventually to acquire the Empire of the Near East. During the conference in London between the plenipotentiaries of the belligerents, parallel meetings took place between the representatives of the great powers, whose relations with each other were strained and difficult in the extreme. The Turkish envoys prolonged the negotiations, as was their custom; they naturally were unwilling to concede their European provinces to the despised and hated Greek and Slavonic conquerors, but the delays implied growing hardships for their besieged and starving garrisons in Thrace, Epirus, and Albania. On January 23, 1913, a quasi-revolution occurred in the Turkish army, headed by Enver Bey and other Young Turk partisans, and approved by the Austrian and German embassies, with the object of interrupting the negotiations and staking all on the result of a final battle. As a result of these events, and of the palpable disingenuousness of the Turks in continuing the negotiations in London, the Balkan delegates on January 29 broke them off, and on February 3, 1913, hostilities were resumed. At length, after a siege of nearly five months, Adrianople, supplied with infinitely better artillery than the allies possessed, was taken by the combined Serbian and Bulgarian forces on March 26, 1913. The Serbian troops at Adrianople captured 17,010 Turkish prisoners, 190 guns, and the Turkish commander himself, Shukri Pasha.
