HMS Vortigern was a V-class destroyer of the Royal Navy, constructed during World War I. Ordered from J. Samuel White of Cowes during the 1916–17 Programme Build, she was laid down on 17 January 1917, launched on 5 October 1917, and commissioned on 21 January 1918. She was named after Vortigern, an early British ruler, and remains the only Royal Navy ship to bear this name. Designed as a fast and agile warship, Vortigern served initially in the final months of World War I, and after the war, she was redeployed to the Baltic Sea in 1919, functioning with the 1st Destroyer Flotilla. Eventually, she was placed in reserve but was reactivated in 1939, participating in the August Fleet Review by King George VI. With the outbreak of World War II, Vortigern was assigned to the 17th Destroyer Flotilla based at Plymouth. Her primary duties included convoy escort and anti-submarine patrols in the South Western Approaches and the English Channel. In January 1940, she was transferred to the 13th Destroyer Flotilla at Gibraltar, escorting convoys such as OG 14F to Gibraltar and conducting patrols between Britain and Gibraltar. Notably, Vortigern participated in the attack on the French fleet at Mers-el-Kébir (Operation Catapult) in July 1940, and later screened capital ships during operations against Italian targets. She was temporarily refitted in September 1940 to be converted into a Short Range Escort, serving in the North Sea with the 12th Destroyer Flotilla from late 1940 into 1942. Her service ended on 15 March 1942, when she was sunk off Cromer by a German E-boat, S104, while defending a coastal convoy. The attack resulted in the loss of 110 crew members, with only 14 survivors. The wreck is designated as a Protected Place under the Protection of Military Remains Act 1986, and her sinking is commemorated among the war graves in the area.
