The Gestapo dragged in a lot of low-level SS agents and forced them to execute 2 to 3 prisoners. Sinners don’t like to do their dirty work alone. The one that did the actual shooting of the two senior officers was hunted down after the war and executed. I think it was in “The True Story of Stalag III”. The officers that tracked him down didn’t feel a lot of satisfaction. It was really quite sad as the shooter was just a shoe salesman before the war and had three young daughters and was really a bit of a wimp. He had been ordered to shoot and had an officer with him. It was a good book.
This miniseries was shown on NBC in November 1988...
