Since my posting in May I have now established that we have a Bernhard Rogge from the Atlantis and a Walter Rogge at the Marlag und Milag P.O.W. camp, both being Crew 15, and as the name has been used a lot without a first name this has added to the confusion,
The photographs used in most cases are of Bernhard Rogge, and the tales by the ex P.O.Ws seem to have added to the confusion.
Hope this info will assist anyone in the future
