HMS Foresight was one of nine F-class destroyers built for the Royal Navy during the 1930s. She was assigned to the Home Fleet upon completion. Unlike her sister ships, she does not appear to have been attached to the Mediterranean Fleet in 1935–36 during the Abyssinia Crisis, nor did she enforce the arms blockade imposed by Britain and France on both sides of the conflict the Spanish Civil War of 1936–1939. 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. Foresight was sent to Gibraltar in mid-1940 and formed part of Force H where she participated in the attack on Mers-el-Kébir and the Battle of Dakar. The ship escorted numerous convoys to Malta in 1941 and Arctic convoys during 1942. Later that year, Foresight participated in Operation Pedestal, another convoy to Malta. She was torpedoed by an Italian aircraft on 12 August and had to be scuttled the next day.

The attack on Mers-el-Kébir on 3 July 1940, during the Second World War, was a British naval attack on neutral French Navy ships at the naval base at Mers El Kébir, near Oran, on the coast of French Algeria. The attack was the main part of Operation Catapult, a British plan to neutralise or destroy neutral French ships to prevent them from falling into German hands after the Allied defeat in the Battle of France. The British bombardment of the base killed 1,297 French servicemen, sank a battleship and damaged five other ships, for a British loss of five aircraft shot down and two crewmen killed. The attack by air and sea was conducted by the Royal Navy, after France had signed armistices with Germany and Italy, coming into effect on 25 June.
