The Battle of Maguelone was a minor naval action that occurred in late October 1809, during the Peninsular War, between the escort of a French convoy, comprising three ships of the line and two frigates, and a 6-ship strong squadron of the Royal Navy. In a running battle, the French covered the retreat of the convoy and attempted to escape by sailing in shallow waters close to the shore of Maguelone. After two of the ships of the line ran aground, their crew evacuated them and scuttled them by fire after removing valuable equipment, including the artillery. The remaining ship and frigates made good their escape to Toulon. A British cutting-out party attacked the convoy in Baie des Roses on 1 November, destroying most of it and capturing three ships.
