As Russian forces withdrew from the front following the October Revolution, a small Armenian volunteer force took up positions to defend the town from the approaching Ottoman Army. On March 6, 1918, the Ottoman army, along with the help of the town's Muslims, overwhelmed Ardahan's Armenian garrison and retook the town. The British occupied Ardahan after the end of the First World War and eventually handed control over it to the Democratic Republic of Armenia. When the Turkish Nationalists captured Ardahan in November 1920, the town's remaining Armenians, Pontic Greeks, and Georgians fled to Armenia, northern Greece, and Georgia. The Treaty of Moscow, signed the following year between the Soviets and the Turks, confirmed Ardahan as a part of Turkish territory.
