HMS Harvester was an H-class destroyer originally ordered by the Brazilian Navy with the name Jurua in the late 1930s, but bought by the Royal Navy after the beginning of World War II in September 1939. Almost immediately after being commissioned, 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 May 1941, but her anti-aircraft armament was deemed too weak and she was transferred to the Newfoundland Escort Force in June 1941 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. Harvester had her rear torpedo tubes replaced by a 12-pounder AA gun after the evacuation of Dunkirk in 1940, but it is not known exactly when this modification was made. During her 1942 conversion to an escort destroyer, the ship's short-range AA armament had been augmented by two Oerlikon 20 mm guns on the wings of the ship's bridge. The .50-calibre machine gun mounts were replaced by a pair of Oerlikons later. 'A' gun was replaced by a Hedgehog anti-submarine spigot mortar. The ship's director-control tower and rangefinder above the bridge were removed in exchange for a Type 271 target indication radar. A Type 286 short-range surface search radar was probably also fitted midway through the war. The ship also received a HF/DF radio direction finder mounted on a pole mainmast.[3] Jurua was ordered by Brazil on 6 December 1937 from Vickers-Armstrongs, Barrow-in-Furness. The ship was laid down on 3 June 1938 and she was purchased by the British on 5 September 1939 and renamed HMS Handy. The ship was launched on 29 September 1939 and renamed Harvester in January 1940 as her original name was thought too liable to be confused with Hardy. Harvester was commissioned on 23 May and briefly worked up at Portland Harbour before she was assigned to the 9th Destroyer Flotilla.[6] The ship joined the Dunkirk evacuation on 29 May and returned 272 men to Dover during the day. However, the situation at Dunkirk soon became too dangerous to risk the larger and more modern destroyers, so Harvester made no attempt to evacuate any troops during daylight hours on 30 May. This decision was rescinded during the day on 30 May and the ship sailed for Dunkirk on the night of 30/31 May. En route she was narrowly missed by two torpedoes, but she rescued 1341 men in two trips on 31 May and an additional 576 on 1 June.[7] Harvester was lightly damaged by strafing German aircraft that same day and required repairs that were made at Chatham. On 9 June the ship was ordered to Le Havre, France, to evacuate British troops, but none were to be found. She loaded 78 men at Saint-Valery-en-Caux on 11 June. Later in the month she escorted ships evacuating refugees and troops from Saint-Nazaire and St. Jean de Luz (Operation Aerial).[8] Winser, John de D (1999). B.E.F. Ships Before, At and After Dunkirk.
