The Adriatic campaign of 1807–1814 was a struggle for supremacy in the Adriatic Sea between the French Navy and the British Royal Navy during the Napoleonic Wars. The early stages of the campaign saw extensive activity between rival frigate squadrons, climaxing at the Battle of Lissa in 1811 at which the last major French force was destroyed and its commander killed. The subsequent campaign was characterised by sustained raids by British warships on French and Italian convoys, warships and coastal positions across the Adriatic, culminating in the capture of several key French port cities in 1813, during the War of the Sixth Coalition.
