German submarine U-1200

German submarine U-1200 was a German Type VIIC U-boat of the Kriegsmarine which saw service during the Second World War.

Service history
U-1200 keel was laid down 17 April 1943, by F. Schichau, of Danzig. She was commissioned 5 January 1944 under the command of O/L H Mangels.

She was assigned to 8th U-boat Flotilla for training, before joining 11th U-boat Flotilla in Norway for operational service.

Her first war patrol, on 7 October 1944, was cut short with mechanical difficulties; she returned to Bergen on 17 October. Two days later on 19 October she set out again for her patrol area in the South-Western Approaches, south of Ireland.

Fate
On the night of 10 November 1944, 60 miles south of Cape Clear, Ireland, she encountered units of the Royal Navy's 30 Escort Group. These were four Castle-class corvettes, Pevensey Castle, Kenilworth Castle, Launceston Castle and Portchester Castle, led by Cdr. Denys Rayner. Mistaking the group, which was engaged in a slow sweep of its patrol area, for a small convoy, U-1200 attempted to stalk the group, steering on a converging course. In a swift and well-executed attack, the ships of 30 EG rounded on the U-boat and destroyed her in one depth-charge attack. There were no survivors.
