HMS Campbeltown was a Town-class destroyer of the Royal Navy, originally commissioned in the US Navy as USS Buchanan, a Wickes-class destroyer laid down on 29 June 1918 and launched on 2 January 1919. She was commissioned into the US Navy on 20 January 1919 and served during the inter-war period before being placed into reserve in 1939. As part of the Destroyers for Bases Agreement, she was transferred to the Royal Navy on 3 September 1940 and commissioned at Halifax, Canada, on 9 September 1940. Following her transfer, HMS Campbeltown underwent modifications at Devonport Dockyard to prepare for her Royal Navy service, joining the 17th Flotilla operating in the Western Approaches. Early in her RN career, she was involved in collision incidents and convoy escort duties, including sinking the British coaster Fiddown in the Mersey Estuary on 29 November 1940. She also briefly served in the Royal Netherlands Navy as HNLMS Campbeltown from 17 January to 15 October 1941, during which she was renamed Middelburg but retained her original name due to agreements. Her most notable service was in the planned Operation Chariot in 1942, a daring raid on the German-held dock at Saint-Nazaire. Selected as the expendable ram-ship, Campbeltown was extensively modified: her funnels were shortened and raked to resemble a German torpedo boat, and she was equipped with a 12-pounder gun, eight Oerlikon anti-aircraft cannons, extra armor, and a large explosive charge of 24 Mark VII depth charges packed with amatol. On March 26, 1942, she led a flotilla of 21 vessels across the English Channel to France, where she rammed the dock gates at Saint-Nazaire at 01:34 on March 28. The explosion and subsequent demolition of the drydock significantly hindered German naval operations for the remainder of the war. HMS Campbeltown's participation in the raid made her one of the most famous destroyers of WWII, and her crew, including her captain Lieutenant Commander Stephen Beattie, received numerous decorations, including the Victoria Cross. The ship's bell was later given to the town of Campbelltown, Pennsylvania, as a symbol of gratitude. Her legacy endures through her pivotal role in one of the war’s most daring and impactful commando operations.
