In 1514, while the Safavid forces were at Chaldiran and planning on how to confront the Ottomans, who had declared war against the Safavid Empire. Mohammad Khan Ustajlu, who served as the governor of Diyabakir, and Nur-Ali Khalifa, a commander who knew how the Ottomans fought, proposed that they should attack as quickly as possible. However, this proposal was rejected by Durmish Khan, who rudely said that Muhammad Khan Ustajlu was only interested in the province which he governed. The proposal was also rejected by Ismail himself, who said; "I am not a caravan-thief, whatever is decreed by God, will occur." A battle shortly ensured, which, however, resulted in an absolute disaster for the Safavids, who lost most of their troops and commanders.
