After marching across the desert the army arrived in Gaza, where it rested for two days, and then moved onto Jaffa. This city was surrounded by high walls flanked by towers. Jezzar had entrusted its defence to elite troops, with the artillery manned by 1,200 Ottoman gunners. The city was one of the ways into Syria, its port could be used by his fleet and a large part of the expedition's success depended on its fall. This meant Bonaparte had to capture the city before advancing further, and so he laid siege to it from 3–7 March.
