Discontent against the French led to an uprising by the people of Cairo. While Bonaparte was in Old Cairo, the city's population began spreading weapons around to one another and fortifying strongpoints, especially at the Al-Azhar Mosque. The French responded by setting up cannons in the Citadel and firing them at areas containing rebel forces. During the night, French soldiers advanced around Cairo and destroyed any barricades and fortifications they came across. The rebels soon began to be pushed back by the strength of the French forces, gradually losing control of their areas of the city. Back in absolute control of Cairo, Bonaparte sought out the authors and instigators of the revolt. Several sheikhs, along with various people of influence, were convicted of participation in the plot and executed. To complete his punishment, a heavy tax was placed upon the city and its divan was replaced by a military commission.
