The Warwick Deeping was built in 1934 by Cochrane & Sons Shipbuilders of Selby for the Newington Steam Trawling Company of Kingston upon Hull as a North Sea fishing trawler.
She was acquired by the Admiralty in August 1939 and converted into an anti-submarine patrol vessel, armed with a single 4inches gun, machine guns, depth charges, and fitted with ASDIC, and assigned to the 17th Anti-Submarine Group at Portsmouth.
At 22:30 on the night of 11–12 October 1940 she was on patrol in the English Channel, about 10nmi south of the Isle of Wight, in company with HMS Listrac (former French armed merchant ship),[1] when she encountered five German torpedo boats; Falke, Wolfe, Greif, Kondor and Seeadler which had sailed from Cherbourg to sortie along the English coast.[2] The two British ships soon found themselves under fire, and Listrac, believing that the German ships were Royal Navy vessels attacking in error switched on her identification lights. She was promptly shelled, causing a large explosion aboard, and then torpedoed and sunk, with the loss of her captain and 11 men.[3] The Warwick Deeping attempted to escape, but was relentlessly attacked, and hit by a torpedo, which failed to explode. She was hit several times by shells, one of which finally disabled her engines. Now helpless and sinking, the crew abandoned the ship, but instead of delivering the coup de grace the German torpedo boats unexpectedly broke off their attack and sailed away. An hour later all 22 crew were rescued.[4]
The Warwick Deeping lies in of water at and is a popular wreck diving site.
