In addition to these provisions, a secret clause obligated the Armenians and Russians to demobilize their forces in both western and eastern Armenia. Having killed and deported most of Armenians of Western Armenia during the Armenian genocide, the Ottoman Empire intended to eliminate the Armenian population of Eastern Armenia.

Beginning on May 21, the Ottoman army moved ahead again.
