On 19 August a letter was brought to Nader bearing news of the outcome of the battle of Mosul. Nassrollah Mirza had crushed the Ottoman army sent to the Mosul Eyalet and was requesting the Shah's permission to advance deeper into Ottoman Mesopotamia. Nader Shah ordered this letter to be taken to Yegen Pasha in a bid to convince him of the futility of further resistance. However, as the Persian emissaries entered the encampment they found the Ottoman troops had risen in mutiny. It is unclear as to whether they rose in mutiny after hearing of Yegen Pashah's suicide or in fact, had killed Yegen Pasha in an act of mutiny. after of the Ottomans broke away from the camp and fled desperately. The Ottoman soldiers screamed "oh people of Mohammad, flee, flee!" as they were ruthlessly pursued and cut down by the Persian cavalry.
