The Battle of the Audierne Bay was an engagement between German and Allied naval flotillas that took place on 23 August 1944, during World War II. Three Allied warships, which had already established control off the coast of Brittany and were lurking off Audierne south of the invested fortress of Brest, intercepted and sank eight German vessels of an armed convoy. This was the conclusion of Operation Kinetic; an allied plan to intercept shipping and hinder Germans besieged at Brest.
