HMS Wivern (D66, later I66) was a Modified W-class destroyer of the British Royal Navy, built during the final years of World War I. Ordered in April 1918 as part of the 13th Naval Programme, she was laid down on 19 August 1918 by J. Samuel White at Cowes, Isle of Wight. She was launched on 16 April 1919 and completed by 23 December 1919, entering service with the Royal Navy with the pennant number D66. Constructed as a relatively large and fast destroyer, Wivern served initially with the 3rd Destroyer Flotilla in the Atlantic and Mediterranean Fleets. After a period in reserve, she was recommissioned in 1939 at the outbreak of World War II, initially assigned to the 16th Destroyer Flotilla at Portsmouth but quickly transferred to Western Approaches Command for convoy defense. Throughout the war, Wivern was heavily engaged in convoy escort and patrol duties across the North Sea, Atlantic, and Mediterranean. She participated in key operations such as the evacuation of Allied personnel from Hook of Holland in May 1940, and was involved in anti-invasion patrols off the UK coast during the Battle of Britain. She also supported Allied amphibious operations in North Africa, including escorting convoys during Operation Torch and engaging German submarines, notably contributing to the sinking of U-660 in November 1942. In 1943, Wivern sustained structural damage while rescuing survivors from the sinking HMCS Weyburn and was towed to the UK for extensive repairs and a refit, which included replacing her forward armament. After her repairs, she returned to service in 1944, primarily operating in the North Sea, countering German E-boats, and escorting convoys. In 1945, she was involved in anti-submarine operations, claiming a share in the sinking of U-714, although the U-boat was credited solely to the Royal Canadian Navy frigate HMS Natal. Wivern's wartime service ended following Germany's surrender, and she was decommissioned in 1945. She was sold for scrap in 1947 and dismantled at Charlestown, Fife, in 1948. Her service record highlights her as a versatile and resilient vessel, actively contributing to convoy protection, anti-submarine warfare, and support of Allied operations during WWII.
