The Ottoman commander, Abdullah Pasha, marched into Mosul Eyalet where he was joined by the local Ottoman forces as well as a significant body of Kurdish auxiliaries. However, when the Persian army gave battle it inflicted a crushing defeat. The severity of the Ottoman defeat was such that Nassrollah Mirza wrote to his father, Nader, requesting permission to escalate the situation into a full-scale invasion of Ottoman Iraq. The letter reached Nader Shah on the last day of the Battle of Kars where Nader had also gained an overwhelming victory against Yegen Pasha.
