Napoleon orders a withdrawal from his siege of city of Acre due to plague which run through besieging French forces. To conceal its withdrawal from the siege, the army set off at night. Arriving at Jaffa, Bonaparte ordered three evacuations of the plague sufferers to three different points – one by sea to Damietta, one by land to Gaza and another by land to Arish. Finally, after four months away from Egypt, the expedition arrived back at Cairo with 1,800 wounded, having lost 600 men to the plague and 1,200 to enemy action.
