In June 1944, the Nazis locked eighteen-year-old Dave Hersch into a railroad boxcar and shipped him from his hometown of Dej, Hungary, to Mauthausen Concentration Camp, the harshest, cruelest camp in the Reich. After ten months in the granite mines of Mauthausen's nearby sub-camp, Gusen, he weighed less than 80lbs, nothing but skin and bones._ Dave often told his story of survival and escape, and his son, Jack, thought he knew it well. But years after his father's death, he came across a photograph of his father on, of all places, the Mauthausen Memorial's website. It was an image he had never seen before - and it propelled him on an intensely personal journey of discovery. 'Death March Escape' is an intriguing book which I read cover to cover.
