The
Battle of Lissa (sometimes called the
Battle of Vis; ; ; ) was a naval action fought between a British
frigate squadron and a substantially larger squadron of French and Venetian frigates and smaller ships on 13 March 1811 during the
Adriatic campaign of the
Napoleonic Wars. The engagement was fought in the
Adriatic Sea for possession of the strategically important island of
Lissa (also known as Vis), from which the British squadron had been disrupting French shipping in the Adriatic. The French needed to control the Adriatic to supply a growing army in the
Illyrian Provinces, and consequently dispatched an invasion force in March 1811 consisting of six frigates, numerous smaller craft and a battalion of Italian soldiers.
