The book would be an interesting read.
I’m curious as to what happened in real life corresponding to the movie’s portrayal of makeshift pants used to release tunnel dirt...
Human Game: The True Story of the 'Great Escape' Murders and the Hunt for the Gestapo Gunmen
My Father was in Stalag Luft III during the tunneling, but as an American, was moved out of the camp prior to the escape - actually left Jan 28, 1945 for another camp in Nurnberg. I still have his POW log book that the Red Cross provided the men in camps back then - and it’s a fascinating thing to read. He was quite an artist and there’s even a drawing he made of the memorial built in Mar 1944 in an RAF cemetary and dedicated to 50 men killed in the escape from Stalag Luft III in Sagan, Germany. When I was younger, I remember him telling me he participated in the dirt dumping so I believe the portrayal in the movie was accurate as to how it was accomplished.
