26 Oct 1943
The target of the depth charge attack on 26 Oct. 1943 in the Atlantic in postion 50.49N 41.01W by a Canadian B-24 Liberator (RCAF Sqdn. 10/A), formerly credited with sinking U-420, was in fact U-91, which escaped unscathed. U-91 was searching for U-584 to supply her with fuel.

31 Oct 1943
Avengers from the USS Card found U-91 refuelling U-584 and called in other aircraft. After initially repelling them with flak, U-91 dived while U-584 stayed on the surface. U-584 was sunk with all hands by Fido homing torpedoes when she attempted to dive. U-91 escaped unscathed and escaped the subsequent search. (Sources: Blair, vol 2, page 438)
