The Mamluks entered Palestine to confront the Mongol army that Hulagu left behind under the command of Kitbuqa. In September 1260, the two sides met in the plains south of Nazareth in a major confrontation known as the Battle of Ain Jalut. Qutuz had some of his cavalry units hide in the hills around Ain Jalut (Goliath's Spring), while directing Baybars's forces to advance past Ain Jalut against Kitbuqa's Mongols. In the ensuing half-hour clash, Baybars's men feigned a retreat and were pursued by Kitbuqa. The latter's forces fell into a Mamluk trap once they reached the springs of Ain Jalut, with Baybars's men turning around to confront the Mongols and Qutuz's units ambushing the Mongols from the hills. The battle ended in a Mongol rout and Kitbuqa's capture and execution. Afterward, the Mamluks proceeded to recapture Damascus and the other Syrian cities taken by the Mongols. Upon Qutuz's triumphant return to Cairo, he was assassinated in a Bahri plot. Baybars subsequently assumed power in Egypt in late 1260, and established the Bahri Mamluk sultanate.
