Hundreds of thousands of British and American servicemen were held as POW's in camps across Nazi Germany by time of the Normandy landings in June 1944. As winter settled across Europe and the Allied advance threatened German borders, prisoners were moved away from liberating forces.
The POWs were forced to march hundreds of miles in appalling conditions. Hundreds died of disease, starvation and exhaustion. Yet when the war was over those who survived found their extraordinary tale was largely ignored and forgotten.
Now, John Nichol and Tony Rennell bring the survivors' amazing stories to light, telling one of the most courageous and brutal tales of the final months of the Second World War.
