On May 11, a new peace conference opened at Batum. At this conference the Ottomans extended their demands to include Tiflis as well as Alexandropol and Echmiadzin; they also wanted a railroad to be built to connect Kars and Julfa with Baku. The Armenian and Georgian members of the Republic's delegation began to stall. Beginning on May 21, the Ottoman army moved ahead once again. The ensuing conflict led to the Battle of Sardarapat (May 21–29), the Battle of Kara Killisse (1918) (May 24–28), and the Battle of Bash Abaran (May 21–24). On May 28, 1918, Georgia, signed the Treaty of Poti with Germany, and welcomed the prospect of a German expedition, seeing the Germans as protectors against the post-Russian Revolution havoc and the Ottoman military advances.
