Siege of Acre (1799) in the context of "French campaign in Egypt and Syria"

The French invasion of Egypt and Syria (1798–1801) was a military expedition to Ottoman-held Egypt and Syria led by Napoleon Bonaparte during the French Revolutionary Wars. The campaign aimed to undermine British trade routes, expand French influence, and establish a scientific and administrative presence in Egypt. Napoleon also sought to sever Britain's connection to its colonial holdings in India, with the long-term ambition of challenging British dominance in the region.

Departing from Toulon in May 1798, Napoleon’s fleet, comprising around 36,000 troops, landed in Alexandria on 28 June. Advancing rapidly, he defeated the ruling Mamluks at the Battle of the Pyramids, securing control of Cairo and establishing a French administration. The campaign, however, was soon compromised by the destruction of the French fleet at Aboukir Bay by Horatio Nelson, which cut off French reinforcements and supplies. French rule faced resistance, including the Cairo uprising (1798), which was suppressed with significant casualties. Seeking to consolidate French gains, Napoleon advanced into Ottoman Syria, aiming to preempt an Ottoman counteroffensive, but his campaign ended in failure at the Siege of Acre (1799), where Anglo-Ottoman forces, supported by the Royal Navy, repelled French assaults.

In the Battle of Aspern-Essling (21–22 May 1809), Napoleon crossed the Danube near Vienna, but the French and their allies were attacked and forced back across the river by the Austrians under Archduke Charles. It was the first time Napoleon had been personally defeated in a major battle, as well as his first battle defeat in 10 years since the siege of Acre, and his first battle defeat as head of state, although he did suffer a tactical defeat in the Battle of Caldiero and in the Second Battle of Bassano. Archduke Charles drove out the French but fell short of destroying their army. The French lost over 20,000 men, including one of Napoleon's ablest field commanders and closest friends, Marshal Jean Lannes.
