Attacks on U-91 during this patrol
26 Oct 1943
The attack on 26 Oct, 1943 in the North Atlantic, in postion 50.49N, 41.01W, by depth charges from a Canadian B-24 Liberator aircraft (RCAF Sqdn. 10/A) formerly credited with sinking the U-420.
This attack was in fact against U-91 inflicting no damage. U-91 was seeking U-584 to give her fuel.
(Sources: 1996-01-01, Axel Niestle)31 Oct 1943
While attempting the fuel the U-584 Avenger aircraft from the carrier Card found the boats and brought in other aircraft. After initially repelling them with flak U-91 dived while the other boat stayed on the surface a bit longer. U-584 was destroyed with all hands by Fido homing torpedoes when attempting the dive. U-91 escaped this attack and the following hunt. (Sources: Blair, vol 2, page 438)
