HMS Harvester was a H-class destroyer originally ordered by the Brazilian Navy with the name Jurua in the late 1930s, but was bought by the Royal Navy after the beginning of World War II in September 1939. Almost immediately after commissioning, in May 1940, the ship began evacuating Allied troops from Dunkirk and other locations in France. Afterwards she was assigned to the Western Approaches Command for convoy escort duties. Harvester and another destroyer sank a German submarine in October. She was briefly assigned to Force H in 1941, but her anti-aircraft armament was deemed too weak and she was transferred to the Newfoundland Escort Force the next month for escort duties in the North Atlantic. The ship was returned to the Western Approaches Command in October 1941 and was converted to an escort destroyer in early 1942. Harvester was torpedoed and sunk in March 1943 by a German submarine after having rammed and sunk another submarine the previous day while escorting Convoy HX 228.
