"Courbet" sailed for Portsmouth on 20 June. She was also seized there on 3 July and was turned over to the Free French a week later who used her as a depot and an anti-aircraft ship in Portsmouth until 31 March 1941 when she was disarmed. She remained in use as a depot ship and target until she was scuttled as a breakwater on 9 July 1944 for a Mulberry harbour used during the Battle of Normandy. She was scrapped in place after the war.
