The Battle of Dilman (April 15, 1915) was a battle fought at Dilman between the Russian Empire and the Ottoman Empire. More than half of the Ottoman troops were Kurdish, almost all of whom deserted. The result was a Russian-Armenian victory under Tovmas Nazarbekian and Andranik Ozanian. Apart from the Armenian officers who served under Tovmas Nazarbekian's Russian Caucasus Army, the Armenians also deployed a volunteer battalion under the leadership of their commander Andranik and with the participation of Smbat Baroyan.
