Battle of Aga-Cayiri

Battle of Ağaçayırı was a battle between the army of the Ottoman Empire under the command of Hadım Ali Pasha and the army of the Mamluk Sultanate led by Emir Ozbay (Ozbek). The battle began on August 16, 1488, between Tarsus and Adana during the First Ottoman–Mamluk War, and ended the next day in favor of the Mamluk army. In 1488, the Mamluk army on the way to Adana was caught in a trap at the exit of the Belen Pass near Iskenderun. The Ottoman fleet, commanded by Hersekli Ahmed Pasha, was on standby and fired upon the vanguard of the Mamluk army. However, the fleet was later caught in a storm, which allowed the Mamluk army to pass into the Çukurova lowlands.

At this time, the Ottoman army was busy restoring the destroyed fortifications of the cities. Camping near Ağaçayırı, roughly halfway between Adana and Tarsus, the Mamluks rested for two or three days until the Ottoman army approached. The Mamluks attacked the Ottomans the same day to prevent their soldiers from resting. Initially, the advantage was with the Ottomans, but the death of several commanders on their right flank led to confusion and retreat. At night, Ali Pasha withdrew to Ereğli. This was the third major Ottoman defeat in the Ottoman–Mamluk War, resulting in the temporary loss of part of Cilicia by the Ottomans.
