Early phases According to Turkish and Soviet sources, Turkish plans to take back formerly Ottoman-controlled lands in the east were already in place as early as June 1920. Using Turkish sources, historian Bilâl Şamşir has identified mid-June as to when exactly the Ankara government began to prepare for a campaign in the east. Hostilities were first begun by Kemalist forces.
Kâzım Karabekir was assigned command of the newly formed
Eastern Front on 9 June 1920 and was given authority over a
field army and all civil and military officials in the Eastern Front on 13 or 14 June. Skirmishes between Turkish and Armenian forces in the area surrounding Kars were frequent during that summer, although full-scale hostilities did not break out until September. Convinced that the Allies would not come to the defense of Armenia and aware that the leaders of the Republic of Armenia had failed to gain recognition of its independence by Soviet Russia, Kemal gave the order to commanding general Kâzım Karabekir to advance into Armenia. At 2:30 in the morning of 13 September, five battalions from the Turkish
XV Army Corps attacked Armenian positions, surprising the thinly spread and unprepared Armenian forces at
Oltu and
Penek. By dawn, Karabekir's forces had occupied Penek and the Armenians had suffered at least 200 casualties and been forced to retreat east towards
Sarıkamış. As neither the Allied powers nor Soviet Russia reacted to Turkish operations, on September 20 Kemal authorized Karabekir to push onwards and take
Kars and
Kağızman. By this time, Karabekir's XV Corps had grown to the size of four divisions. At 3:00 in the morning of 28 September, the four divisions of the XV Army Corps advanced towards Sarıkamış, creating such panic that Armenian residents had abandoned the town by the time the Turks entered the next day. The armed forces started toward Kars but were delayed by Armenian resistance. In early October, the Armenian government pleaded that the Allies intervene and put a halt to the Turkish advance, but to no avail. Most of Britain's available forces in the Near East were concentrated on crushing the
Kurdish tribal uprisings in
Iraq with the help of the
Assyrians, while France and Italy were also fighting the Turkish revolutionaries near Syria and Italian controlled
Antalya. Neighboring Georgia declared neutrality during the conflict. On 11 October, Soviet plenipotentiary
Boris Legran arrived in
Yerevan with a text to negotiate a new Soviet-Armenian agreement. The Turkish national movement was not happy with possible agreement between the Soviets and Armenia. Karabekir was informed by the
Government of the Grand National Assembly regarding the Boris Legran agreement and ordered to resolve the Kars issue. The same day the agreement between Armenia and Soviet Russia was signed, Karabekir moved his forces toward Kars.
Capture of Kars and Alexandropol On 24 October, Karabekir's forces launched a new, massive campaign against Kars. Turkish forces continued to advance, and, a week after the capture of Kars, took control of Alexandropol (present-day
Gyumri,
Armenia).
Treaty of Alexandropol '', 10 December 1920 The Turks, occupying Alexandropol (today called
Gyumri), presented the Armenians with an ultimatum which they were forced to accept. They followed it with a more radical demand which threatened the existence of Armenia as a viable entity. The Armenians at first rejected this demand, but when Karabekir's forces continued to advance, they had little choice but to capitulate. The decision to sign the illegal treaty was justified by Khatisyan as necessary to prevent Karabekir's army from advancing further and reaching
Echmiadzin and Yerevan ahead of the Red Army. A majority of the Armenian leadership agreed that it was impossible to resist both the Russians and the Turks and that the Armenian army and population were exhausted.
Drastamat Kanayan and Hambardzum Terterian were authorized to enter negotiations with Boris Legran to accept Soviet rule in Armenia. On 2 December 1920, the Armenian government signed an agreement with Legran declaring its resignation and the transfer of power in Armenia to a Soviet government. Drastamat Kanayan would temporarily lead the country pending the arrival of the Armenian Revolutionary Committee in Yerevan. With the mass flight of Armenians from the regions designated for Turkish annexation, Karabekir proposed a
plebiscite based on self-determination, echoing the procedure the Ottomans had used to legitimize the seizure of Kars after the
Treaty of Brest-Litovsk. Karabekir initially attempted to include text in the treaty that claimed that Armenians had never formed a majority in any part of the Ottoman Empire. == Impact ==
