Attacks on this boat and other events

27 Nov 1943
Aircraft attack, aircraft shot down: British Wellington bomber HF153 (RAF Sqdn 172/O, pilot P/O T.B. Wilkin)

21.22 hrs, Atlantic W of Lisbon: While escorting combined convoys SL 140/MKS 31 from its base on the Azores, the Wellington made a Leigh Light attack and was hit by flak after making an initial strafing run. Its subsequent crash was witnessed by U-262 and U-238 which picked up two survivors, F/S Nicolas J. Martin and Sgt Thomas B. Semple. The other five aircrew were lost. Sgt Semple was the radio operator, and later convinced the Germans during his interrogation that Allied aircraft were able to passively locate U-boats by homing in on their radar detection devices. This deception led to the order to U-boats to turn off their Naxos detectors.

29 Nov 1943
On 29 Nov. 1943 E of the Azores in position 39.33N, 19.01W, aircraft of the US escort carrier USS Bogue depth charged a contact. This attack was thought to have destroyed U-86.

The target was in fact U-764, which escaped unscathed.
