War patrol
U-191 took part in several wolfpack operations in the North Atlantic. On 21 April 1943, she achieved her only success, torpedoing and sinking the 3,025-tonne Norwegian merchant ship Scebli, killing two of Scebli's crew. Two days later U-191 was attacked and sunk by the Royal Navy destroyer HMS Hesperus (H57) off the coast of Greenland south-east of Cape Farewell with the loss of her entire crew of 55 crew.
