Research
Foot & Langley in MI 9 Escape and Evasion state: 'Camp histories of many POW camps in Germany, compiled in the late Summer of 1945 by SBOs and camp IOs - some of them still in a bad temper - fill WO208/3269-95. (No such reports have been found for camps in Italy.) Technically these are all secondary sources, compiled after the events they describe, but written soon afterwards by senior participants who had a proper grasp of their subject matter, and temper apart, wrote with a fairly balanced judgement.'
