HMS Watchman was a W-class destroyer of the British Royal Navy, constructed by John Brown & Company at Clydebank, Scotland. Laid down on 17 January 1917, she was launched on 2 December 1917 and completed by 26 January 1918, entering service the same day. She measured approximately 312 feet in length, with a beam of around 29 feet, and was powered by steam turbines designed for high-speed operations typical of destroyers of her class. Initially assigned the pennant number G23, her designation was later changed to G09 and then D26 during the interwar period. Throughout her service, HMS Watchman played a versatile role in both World Wars. During the final months of World War I, she was part of the Grand Fleet based at Scapa Flow, contributing to fleet operations in the North Sea. Post-war, she participated in notable events such as the Freedom of the City celebrations at Liverpool in 1919, and was involved in the British campaign against Bolshevik forces in the Baltic Sea, engaging Russian warships. In the interwar years, Watchman was part of the 1st Destroyer Flotilla of the Atlantic Fleet and participated in royal cruises, including a visit with King George V and Queen Mary to Jersey in 1921. She also patrolled off Ireland during the Irish Civil War and assisted Irish children at risk from the IRA. Recommissioned in 1939 with the outbreak of World War II, she was assigned to contraband control and convoy escort duties from Gibraltar and later in the Western Approaches. Notably, she participated in operations against Italian submarines, shadowed French battleships, and was involved in Mediterranean operations including testing of British naval response and diversionary attacks with Force H. In 1940, she transferred to the UK to continue Atlantic convoy escort duties, engaging in anti-submarine operations and facing German air and submarine attacks. In 1943, HMS Watchman was converted into a Long-Range Escort, enhancing her capabilities for Atlantic convoy protection. She saw active service in the Arctic, North Atlantic, and Mediterranean, including during Operation Neptune, the Normandy invasion. Her combat record includes sinking the German U-1195 submarine on 7 April 1945. Following the German surrender, HMS Watchman was decommissioned and sold for scrapping in July 1945. She was towed to Inverkeithing, Scotland, where she was dismantled, marking the end of her distinguished service. Her operational history underscores her significance as a versatile and resilient destroyer through pivotal moments of 20th-century naval warfare.
