Hi Nobby,
This was a very difficult one

.
U 68 under Albert Lauzemis arrival in Lorient on 16-06-1943 entering the Scorff-Bunker.The river behind U 68 called ``Port de Guerre``.
She was only five days at sea and had to return damaged,that`s the reason why she is so low in the water,
probably she did not fired any of her torpedos.
I have an original pic of U 170 and this is the same river,this boat also returned damaged on 03-08-1944,Lorient.
However,i am not 100% sure about the VII-C.
my best regards,
Ron.
