On 1 August, the British fleet under Horatio Nelson captured or destroyed all but two French vessels in the Battle of the Nile, defeating Bonaparte's goal to strengthen the French position in the Mediterranean. His army had succeeded in a temporary increase of French power in Egypt, though it faced repeated uprisings. In early 1799, he moved an army into the Ottoman province of Damascus (Syria and Galilee). Bonaparte led these 13,000 French soldiers in the conquest of the coastal towns of Arish, Gaza, Jaffa, and Haifa. The attack on Jaffa was particularly brutal. Bonaparte discovered that many of the defenders were former prisoners of war, ostensibly on parole, so he ordered the garrison and 1,400 prisoners to be executed by bayonet or drowning to save bullets. Men, women, and children were robbed and murdered for three days.
