After training with the 8th U-boat Flotilla at Kiel, U-311 was transferred to the 1st U-boat Flotilla based at Brest in France, for front-line service on 25 November 1943.[1] On that day she departed Kiel and sailed out into the middle of the Atlantic, via the North Sea and the gap between Iceland and the Faroe Islands.[2] She operated as part of 8 wolfpacks[1] before arriving at Brest on 26 January 1944.[3]

Second patrol and loss

U-311 sailed from Brest on 7 March 1944. On the 19th, she sank the Seakay Шаблон:Convert west of Fastnet. On 22 April, she was sunk by depth charges dropped by the Canadian frigates Шаблон:HMCS and Шаблон:HMCS.[4]
