General Events during this patrol


8 Dec 1942. U-221 accidentally rammed U-254 (Gilardone) while the boats were on convoy operations in the North Atlantic. U-254 went down immediately with all but four of her crew (41 dead, including the Commander). U-221 herself was seriously damaged and unable to dive. Trojer abandoned the patrol and made for St. Nazaire, France, reaching base on 23 Dec. He was later absolved of any blame for the accident
