Attacks on U-81 during this patrol
13 Nov 1941
U-81, having recently entered the Mediterranean, learned the British Force H was passing through on its way to Gibraltar. She managed to intercept, and fired from extreme range to sink the aircraft carrier HMS Ark Royal. The destroyer escort delivered a punishing depth charge attack with 130 depth charges counted, but the boat escaped. (Sources: Blair, vol 1, page 396)
