HMS Hyacinth was a Flower-class corvette of the Royal Navy, constructed to serve during the Second World War. As a Flower-class vessel, she featured the typical design of these wartime escort ships, though she retained a distinctive short forecastle due to her Mediterranean service area, which limited access to British shipyards for retrofitting. She was equipped with a 3-inch gun, a notable departure from the more common 4-inch armament found on many sister ships. Hyacinth's operational career was concentrated in the Eastern Mediterranean, where she played a vital role in convoy escort duties, particularly along the Palestine coastline and in supporting the Malta convoys. She was part of the 10th Corvette Group of the Mediterranean Fleet based in Alexandria, operating alongside sister ships Peony and Salvia. Her service was marked by a series of notable anti-submarine actions, achieving three confirmed victories against enemy submarines, a record only matched among her sister ships by Sunflower. One of her significant achievements occurred on 28 September 1941 when she sank the Italian submarine Fisalia northwest of Jaffa, off the coast near Tel Aviv. Later, on 9 July 1942, Hyacinth attacked, damaged, and captured the Italian submarine Perla during a convoy escort from Jaffa to Beirut. The captured Perla was subsequently repaired and commissioned into the Hellenic Navy as Matrosos in 1943. Hyacinth's anti-submarine efforts continued with a notable engagement on 12 September 1943, when in cooperation with the Australian minesweeper Wollongong, she sank the German U-617 after it had been damaged in an attack by Wellington and Swordfish aircraft, shortly after Italy's capitulation. In 1943, Hyacinth was transferred to the Royal Hellenic Navy and renamed Apostolis, after a Greek naval hero. She served out the remainder of the war under the Greek flag, maintaining her significance in maritime escort and anti-submarine warfare during the conflict. After the war, she was returned to the Royal Navy in 1952 and subsequently scrapped the same year.
