sell the remainder—which Saladin purchased himself. In spite of his earlier hesitation to go through with the exchange, he had no doubts about his success, stating that Aleppo was "the key to the lands" and "this city is the eye of Syria and the citadel is its pupil". For Saladin, the capture of the city marked the end of over eight years of waiting since he told Farrukh-Shah that "we have only to do the milking and Aleppo will be ours". After spending one night in Aleppo's citadel, Saladin marched to Harim, near the Crusader-held Antioch. The city was held by Surhak, a "minor mamluk". Saladin offered him the city of Busra and property in Damascus in exchange for Harim, but when Surhak asked for more, his own garrison in Harim forced him out. He was arrested by Saladin's deputy Taqi al-Din on allegations that he was planning to cede Harim to Bohemond III of Antioch. When Saladin received its surrender, he proceeded to arrange the defense of Harim from the Crusaders. He reported to the caliph and his own subordinates in Yemen and Baalbek that he was going to attack the Armenians. Before he could move, however, there were a number of administrative details to be settled. Saladin agreed to a truce with Bohemond in return for Muslim prisoners being held by him and then he gave A'zaz to Alam ad-Din Suleiman and Aleppo to Saif al-Din al-Yazkuj—the former was an emir of Aleppo who joined Saladin and the latter was a former mamluk of Shirkuh who helped rescue him from the assassination attempt at A'zaz. Wars against Crusaders Crusader attacks provoked further responses by Saladin. Raynald of Châtillon, in particular, harassed Muslim trading and pilgrimage routes with a fleet on the Red Sea, a water route that Saladin needed to keep open. Raynald threatened to attack the holy cities of Mecca and Medina. On 29 September 1183, Saladin crossed the Jordan River to attack Beisan, which was found to be empty. The next day his forces sacked and burned the town and moved westwards. They intercepted Crusader reinforcements from Karak and Shaubak along the Nablus road and took prisoners. Meanwhile, the main Crusader force under Guy of Lusignan moved from Sepphoris to al-Fula. Saladin sent out 500 skirmishers to harass their forces, and he himself marched to Ain Jalut. When the Crusader force—reckoned to be the largest the
