The policy of Eastern Armenia (Russian Armenia) already differs from the policy of Western Armenia (Turkish Armenia)

On September 29, Armenian troops were already withdrawing from Sarighamish and Kaghzvan (Western Armenia). In Eastern Armenia, men under 37 are conscripted and the death penalty is imposed in the event of desertion.

On October 14, Armenian forces launched a counterattack. The governor of the Shirak region, Karo Sassouni, writes that the Armenian army numbered about 12,000 people, according to other sources, about 8,000 people. The Armenians did not have a complete assessment of the Turkish forces. Sassouni writes that, according to General Silikyan, the number of Turkish soldiers did not exceed 4,000 men. Only after launching the attack did it become clear that the Turks had much larger forces.

During the attack, fatal flaws in the management of the Armenian army were revealed. Karo Sassouni writes that several military units launched the attack 3-3.5 hours later than planned, so the others could not strengthen their positions and the Turks, regrouping their forces, took the initiative . Minister of Foster Care Artashes Babalyan also says the same thing.

Heavy treaties and decline of the Eastern (Caucasian) part of the First Republic

After the fall of Kars in Western Armenia, although the Armenian army was not completely destroyed and retained significant forces, it continued to retreat under difficult moral and psychological conditions. Desertion had reached considerable proportions. On November 7, Karabekir proposed a truce, which was more of an ultimatum. The Armenian side is forced to accept Turkish demands and leave Alexandropol, but the Turks quickly made new demands: the Armenians had to give in to the Surmalu-Araks Station-Mountain Aragats-Novo Mihailovka-Lorikend line, which was rejected. The attack continued and on November 16, the Turks took Jajur. The Armenian part of the Caucasus agrees to sign a truce and negotiate with the Turks, while appealing to mediation from Moscow.

On November 22, 1920, the Armenian delegation from Yerevan led by Alexander Khatisyan left for Alexandropol to negotiate with the Turks. In about ten days, a difficult reconciliation agreement will be signed on December 2, according to which Caucasian Armenia will lose about 30,000 km², Surmalu and Kars are taken by the Turks, and Zangezur and Nakhjevan by Baku. Caucasian Armenia could not have an army of more than 1,200 soldiers and renounced the Treaty of Sèvres.

On the same days, the agreement on the Sovietization of Caucasian Armenia was also signed in Yerevan.
