HMS Fearless was an F-class destroyer built for the Royal Navy during the 1930s. Although assigned to the Home Fleet upon completion, the ship was attached to the Mediterranean Fleet in 1935–36 during the Abyssinia Crisis. During the Spanish Civil War of 1936–1939, she spent time in Spanish waters, enforcing the arms blockade imposed by Britain and France on both sides of the conflict. Several months after the start of the war in September 1939, Fearless helped to sink one submarine and sank another one in 1940 during the Norwegian Campaign. She was sent to Gibraltar in mid-1940 and formed part of Force H where she participated in the attack on the Vichy French ships at Mers-el-Kébir and the bombardment of Genoa. Fearless helped to sink one final submarine in 1941 and escorted many Malta convoys in the Mediterranean before she was torpedoed by an Italian bomber and had to be scuttled on 23 July 1941.

HMS Forester was one of nine F-class destroyers built for the Royal Navy during the early 1930s. Although assigned to the Home Fleet upon completion, the ship was attached to the Mediterranean Fleet in 1935–36 during the Abyssinia Crisis. A few weeks after the start of World War II in September 1939, she helped to sink one German submarine and then participated in the Second Battle of Narvik during the Norwegian Campaign of 1940. Forester was sent to Gibraltar in mid-1940 and formed part of Force H where she participated in the attack on the Vichy French ships at Mers-el-Kébir and the Battle of Dakar between escorting the aircraft carriers of Force H as they flew off aircraft for Malta and covering convoys resupplying and reinforcing the island until late 1941. During this time the ship helped to sink another German submarine.
