Just to report, that I spent yesterday at "The National Archive" going through WO344 - Liberated POW interrogation Questionnaires. I must admit, I really enjoyed going through them. Sadly for me my Grand Fathers questionnaire didn't have much on it, he hadn't answered the last five questions, which were most important ones i.e. did you escape... and where you successful in carrying out sabotage, etc.. Should I go back to T.N.A, I will look at the file on Stalag 8b, as that looks very interesting and I didn't have enough time to go through it.
