On 29 September 1182, 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 a number of 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 kingdom ever produced from its own resources, but still outmatched by the Muslims—advanced, the Ayyubids unexpectedly moved down the stream of Ain Jalut. After a few Ayyubid raids—including attacks on Zir'in, Forbelet, and Mount Tabor—the Crusaders still were not tempted to attack their main force, and Saladin led his men back across the river once provisions and supplies ran low.
