Ah, just found this pic from the screenshot thread, taken by me during the night of 5-6th of June 1944, WaW I.
Caption says:
Photo taken by U-264 just few hours before leaving Brest to join the other uboats ordered to sink the allied invasion fleet in Normandy. U-264 was sunk on the 7th of June by a Royal Navy destroyers.

IIRC, I came under attack by allied bombers too in Brest shortly after that pic.

Heather, wasnt you the second kaleun from our Flottile to attack the fleet?
