I have just finished reading this book by Colin Rushton. It has had two previous publications by the same author but with different titles; Spectator in Hell (2001) and Auschwitz: A British POW's Eyewitness Account (2013). I visited Auschwitz 1 and Auschwitz Birkenau over two days back in February 2012, during a stay in the beautiful Polish city of Kraków. I knew the two camps were part of a huge industrial complex. However, I didn't know until reading this book, which is based mainly on the account of a British soldier called Arthur Dodd, that allied POW's from all over the European theatre of war were imprisioned in that Hell on Earth. There, they were forced to do skilled war work, (a direct contravention of The Geneva Convention) for the Nazi's, while witnessing first hand and close up, the bestial treatment of the Jewish inmates. It is an incredible story of survival and a strong desire to thwart the Nazi war effort by sabotage and lack of cooperation. Well worth a read.
