HMS Fortune was one of nine F-class destroyers built for the Royal Navy in the mid-1930s. Although she was assigned to the Home Fleet upon completion, the ship was detached to the Mediterranean Fleet to enforce the arms blockade imposed by Britain and France on both sides during the Spanish Civil War of 1936–39. Several weeks after the start of the Second World War in September 1939, Fortune helped to sink a German submarine. The ship escorted the larger ships of the fleet during the early stages of World War II and played a minor role in the Norwegian Campaign of 1940. Fortune was sent to Gibraltar in mid-1940 and formed part of Force H where she participated in the Battle of Dakar against the Vichy French. The ship escorted numerous convoys to Malta in 1940–41 until she was badly damaged
