the peace settlement of the Near East in the form of the Treaty of Sèvres. Under the terms of the treaty, portions of four northeastern vilayets of the Ottoman Empire were allotted to the First Republic of Armenia and subsequently came to be known as Wilsonian Armenia, after the US President Woodrow Wilson. The Treaty of Sèvres served to confirm Kemal's suspicions about Allied plans to partition the empire. According to historian Richard G.

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.

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
