Georg Martin Schädlich was a corporal of the Wehrmacht during World War II, who kept a diary while he was a guard at Colditz castle prisoner-of-war camp from 1941 to 1943.
After service in France he was transferred to his home town to work as a prison guard.
Another diary kept by one of the youngest Musketoon Commandos, Eric Curtis, provides short annotations from the same period.
Later in the war Schädlich lost his life in Italy, dying of a wound to the stomach.
His family kept his diary and many years later his journal was published by his grandson, Thomas Schädlich.
