The Battle of Erzincan was fought in 1473 near Erzincan, Turkey. It was a preliminary battle where Ottoman sultan Mehmed II and Uzun Hasan, the sultan of Aq Qoyunlu, tested each other before the Battle of Otlukbeli.
Before
After taking up battle formation in Sivas, Turkey the Ottoman army continued its march. However, the army's advance became increasingly difficult due to the mountainous terrain. As a result, soldiers had to tie belts to trees and cross the mountain one by one. Despite 40 days of this journey, there was still no news of Uzun Hasan. However, at Niksar, Turkish raiders were attacked by Uzun Hasan's forces. The Ottoman army, having driven them back, raided the surrounding area and finally arrived in Erzincan.
Battle
Here they encountered a force of 5,000 men belonging to Uzun Hasan. Sultan Mehmed saw that Uzun Hasan had sent against the troops of Mehmed Bey of Erzincan and Cemşid Beg. Sultan Mehmed then sent Turahanoğlu Ömer Bey against them. Turahanoğlu Ömer Bey attacked enemy forces of equal size with a 5,000-man cavalry force. The attack resulted in the capture of 50 prisoners and several banners. The Aq Qoyunlu forces, unable to offer significant resistance, retreated towards Tercan. Mahmud and Murad Pashas interpreted this enemy withdrawal differently. While Murad Pasha advocated pursuing the enemy, Mahmud Pasha, an experienced commander, argued that the enemy's withdrawal was a planned trap. If the Euphrates River were crossed, the Ottoman army would be separated, and any encounter could have led to their own disaster.
