Built in 1941 at Vegesack, ''U-254'' was commanded for all her brief career by '' Kapitänleutnant'' Hans Gilardone, except for a brief period of illness, when '' Kptlt.'' Odo Loewe took command for her second patrol. She conducted her warm-up and training period in the Baltic Sea in the first half of 1942, before she was despatched to Kiel from where she participated in her first war operations.

Service history


First patrol

Her first war patrol was a simple one, entailing a passage between Kiel and her new home base in Brest in occupied France. During this month-long journey, ''U-254'' was ordered to spend sometime cruising off Reykjavík, Iceland, hoping to catch some stragglers from northern convoys or supply ships running to the Allied forces stationed on the island. She had one success, sinking a small British freighter on 2 August before she headed for her new home.


Second patrol

Her second patrol was more eventful, when on 3 October, after twelve days of cruising, she spotted the 11,237 GRT American tanker ''Esso Williamsburg'' in the central North Atlantic and sank her with one torpedo, killing 28. This was followed six days later by another success in a similar area, when the British ship was sunk by three torpedoes with all 45 crew on board. The promising career of ''U-254'' was almost cut short on this cruise, when the Norwegian damaged her with

s during an attack on a convoy in the same area as her previous victories.


Third patrol

After repairs, ''U-254'' departed in late November 1942, returning to her old operating grounds of the North Atlantic routes. In December, the weather in the region is atrocious and visibility practically nil, so as ''U-254'' maneuvered to attack Convoy HX 217, to which she had been directed on 8 December, it is perhaps unsurprising that her crew failed to see come steaming out of the gloom and straight into her broadside. The two submarines had become lost in the dark and collided with one another in a freak accident, which claimed 41 of ''U-254''s crew, who were spilled into the ocean as the boat heeled over and sank. Sailors from ''U-221'' dived into the turbulent sea tied to ropes, and succeeded in rescuing four bedraggled survivors of the sinking. ''U-221'' was badly damaged. Unable to dive, ''Oberleutnant zur See'' Trojer aborted the patrol and returned to
