Hi, I too am not convinced with the 'official' report on the demise of the submarine [SS Thompson Lykes], partly that there was no communication from her since sailing, so she could have taken any route, opening up many possibilties of her demise and secondly, given the area of the supposed collision, why seeing as she was not a 'run of the mill'submarine, but unique and secondly if only to confirm the wreck site as she not been located. From the photograph of the Thompson Lykes in J. Rushbridger's book 'Who sank Surcouf', she obviously hit something, being no other allied submarine or U-boat losses reported at this time, Surcouf must be considered. If it was her, then the collision may not have been fatal at the point of impact, but serious enough for her to be unabled to surface, resulting that she met her end some where and time later. I was aware of the American air attack but not the involvment by U69. One question I would have in this theory being, what happened to the four British sailors known to have sailed with Surcouf?. If they were already in French hands, and as they are too missing, they were not left behind when she sailed, why Would they have taken them?. John
