The siege of Acre of 1799 was an unsuccessful French siege of the Ottoman city of Acre (now Akko in modern Israel) and was the turning point of Napoleon's invasion of Egypt and Syria, along with the Battle of the Nile. It was Napoleon's second tactical defeat in his career, three years previously he had been defeated at the Second Battle of Bassano. As a result of the failed siege, Napoleon Bonaparte retreated two months later and withdrew to Egypt.
