HMS Petunia (K79) was a Flower-class corvette constructed by Henry Robb in 1940, designed primarily for convoy escort duties during World War II. Laid down on December 4, 1939, at the shipyard in Leith, she was launched on September 19, 1940, and commissioned on January 13, 1941. The Flower-class vessels, including Petunia, were developed as a rapid, economical solution to bolster the Royal Navy’s convoy protection, especially off the east coast of Britain, and were based on a whaling vessel design. Petunia featured the distinctive "long forecastle" modification, which extended the forecastle aft past the funnel, improving seaworthiness, stability, and crew comfort. Petunia’s wartime service was marked by active convoy escort operations across the Atlantic and as far afield as Sierra Leone. She participated in notable engagements, including the sinking of U-96 in July 1941, where her depth charge attacks contributed to damaging the German submarine after it torpedoed the troopship Anselm Gibraltar, resulting in significant troop losses. In October 1942, Petunia narrowly evaded an attack by the Italian submarine Barbarigo, which fired torpedoes at her but failed to hit. She also rescued survivors from merchant ships sunk by U-boats, underscoring her role in safeguarding vital Allied shipping. Throughout 1943, Petunia continued escorting convoys from Freetown, notably participating in the protection of Convoy SL 125, which suffered heavy U-boat attacks. She was part of the 40th Escort Group and later joined the Western Approaches Command, contributing to the protection of Atlantic convoys until May 1944. In June 1944, she played a role in the Allied invasion of France, escorting assault convoys to Juno Beach during D-Day. Following the end of hostilities, Petunia was placed in reserve and eventually sold to the Chinese Nationalist Government in January 1946, where she was renamed ROCS Fu Bo. Her service ended when she collided with the steamship Haimin in March 1947 near Meizhou Bay, sinking the vessel. Her operational history highlights her importance as a versatile and active escort vessel in the Battle of the Atlantic and the broader maritime efforts of World War II.
