By 9 February, the Austrians had signed the Treaty of Lunéville, ending the war on the continent. The war against the United Kingdom continued (with Neapolitan harbours closed to her by the Treaty of Florence, signed on 28 March). A British expedition landed in Egypt in March, fighting the Battle of Abukir, the Battle of Alexandria and laying siege to Alexandria. The French surrender there on 2 September ended their campaign in Egypt and Syria which had begun in 1798.
