Incorporating troops from vassal countries such as Cilician Armenia and the Kingdom of Georgia, the Mongols had sacked Baghdad in 1258, followed by the taking of Aleppo and Damascus in 1260.
Ghazan defeated Mamluk forces at the Battle of Wadi al-Khazandar that same year, and Damascus quickly surrendered to him.
The Mamluk center and left wings under the command of the emirs Salar and Baibars al-Jashnakir, together with their Bedouin irregulars, then engaged the Mongols.
The next morning, the Mamluks deliberately opened their ranks to allow the Mongols to flee to the river Wadi Arram.
However, while the Mongols were taking on badly needed supplies of water for themselves and their horses, the Sultan was able to attack them from the rear.
[8] According to the medieval Egyptian historian Al-Maqrizi, after the battle, Qutlugh-Shah reached the Ilkhan Ghazan at Kushuf, to inform him of the defeat of his forces.
When the Sultan returned to Cairo, he entered through the Bab al-Nasr (Victory Gate) with chained prisoners of war.
