On 11 May 1918, a new peace conference opened at Batum. At this conference Ottomans extended their demands to include Tiflis as well as Alexandropol and Echmiadzin through which they 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 21 May, the Ottoman army moved ahead once again. The conflict led to the Battle of Sardarapat (21–29 May), the Battle of Kara Killisse (1918) (24–28 May), and the Battle of Bash Abaran (21–24 May).
