Siege of Aleppo (1260)
The siege of Aleppo lasted from 18 January to 24 January 1260. After receiving the submission of Harran and Edessa, Mongol leader Hulagu Khan crossed the Euphrates, sacked Manbij and placed Aleppo under siege. He was supported by forces of Bohemond VI of Antioch and Hethum I of Armenia. For six days the city was under siege. Assisted by catapults and mangonels, Mongol, Armenian and Frankish forces overran the entire city, except for the citadel which held out until 25 February and was demolished following its capitulation.
