قلعة دمشق
Hulagu departed for Karakorum and left Kitbuqa, a Nestorian Christian general, to continue the Mongol conquest. Damascus capitulated after the arrival of the Mongol army, but was not sacked like other captured Muslim cities. However, from Gaza, an-Nasir Yusuf managed to rally the small garrison he left in the Citadel of Damascus to rebel against the Mongol occupation. The Mongols retaliated by launching a massive artillery assault on the citadel and when it became apparent that an-Nasir Yusuf was unable to relieve the city with a newly assembled army, the garrison surrendered.
