I have bought a series of books, called The shoe Leather Express, by a former POW at Stalag Luft IV named Joseph P. O'Donnell. There are six books in all. They have accounts from other former POWs from SL IV and other camps about the life in the camps and how it was on the 86 day 600 mile forced march across Germany during one of Europe's coldest winters. There is also a book enterly of POW drawings and artwork.
His e-mail address is

If you're into POWs and POW camps, these are great books.
If you are interested in the "Death March" try reading
The Last Escape it's enterly dedicated to the evacuation of the POW camps and the Allied Troops marching across Germany. Camps were evacuated because of the advancing Russian front.
