17 April 1945, Royal Navy Destroyer HMS Bulldog.
On May 9, 1941, escorting an OB 318 convoy, HMS Bulldog, with the support of HMS Aubretia and HMS Broadway, attacked and captured U-110 (type IX). British sailors were able to secure a secret machine Enigma and code books.
"HMS Bulldog was responsible for the capture of U-110, her Sub Lt David Balme finding the Enigma code machine ciphers and code books. U-110 was taken on tow and Bulldog kept her afloat for 17 hours then let the towline slip. The intention was to tow U-110 into Iceland but Admiralty realised this would have been a massive error of judgement. In the event, allegedly, U-110 resolved the matter herself by sinking."
"German U-boat U-110 was captured on 9 May 1941 in the North Atlantic south of Iceland by the British destroyers HMS Bulldog (Lt.Cdr. A.J.B. Cresswell, RN) and HMS Broadway (Lt.Cdr. T. Taylor, RN) and the British corvette HMS Aubretia (Lt.Cdr. V.F. Smith, RNR). The U-boat was allowed to sink the day after to preserve the secret capture."
