Jalal ad-Din tried to attack before the merging of the Seljuk and Ayyubid armies, but it was too late, as the Ayyubids had already sent a reinforcement of 10,000 to the Seljuks. The commander of the Seljuk-Ayyubid army was the Seljuk sultan Alaaddin Keykubat I. The battle continued for three days. An able commander, Jalal ad-Din almost defeated the Seljuk-Ayyubid alliance in the first day.
