Hi Lorenzo

At least two air attacks were made on this day in the Bay of Biscay, the one described in your post carried out by Liberator "C" of 59 Sqn RAF in 46°27N/08°43W at 09.07 hours and one carried out by Whitley “G” of 502 Sqn RAF in 43°42N/08°24W at 14.34 hours.

I will research these two air attacks a bit more and publish the details here on uboat.net if time permits, but judging from the time and area the attack on U-620, in which no damage was sustained but one crew member was killed, was carried out by the Whitley. The attack by the Liberator was carried out on U-436 which was badly shaken by the second series of depth charges but managed to reach Lorient safely on 12 November.

Best regards
