Lieutenant Commander David Wanklyn VC DSO (June 28, 1911 – missing in action April 14, 1942) was one of the most successful submariners during WWII.
He applied to join the Royal Navy aged 14. Despite some physical ailments including colour blindness, he was able to pass the selection boards and progressed to a commissioned officer fairly quickly. In 1930 he was assigned to HMS Marlborough, part of the 3rd Battle Squadron and then HMS Renown in September 1931 on which he served with fellow midshipman and future Vice Admiral Peter Gretton. While serving in Renown he was promoted to Sub-Lieutenant and Lieutenant two years later in 1933. By then he had joined the submarine service and served in HMS's Oberon and Shark. By 1939 he was First Lieutenant of HMS Otway.
After the outbreak of WWII, he was given command of HMS H31 which he commanded from February until August 1940. In August 1940 he was given command of newly commissioned HMS Upholder. In December 1940 the submarine was assigned to the Mediterranean. Wanklyn began the first of his patrols in January 1941 and remained on operations in the Med for the remainder of his career.
During 15 months of operations, Wanklyn led Upholder on 27 patrols and sank 8 Italian merchantmen and troopships while damaging two more. He also sank three German merchant ships and damaged one while succeeding in damaging one Vichy French ship. During his combat career he sank one Italian destroyer and one minesweeper and damaged a light cruiser. In a rare achievement, he also sank three Italian submarines. It amounted to 128,353 tons of enemy shipping
For the sinking of the heavily defended enemy transport SS Conte Rosso he received the Victoria Cross.
On 14 April 1942, while on his 28th patrol, Wanklyn and his crew disappeared. He was posted as missing in action. His exact fate remains unknown. Research suggests Upholder was sunk by a combination of an Italian warship and German aircraft.
