Written by a Polish POW captured during the invasion of Poland. Colditz was set up in 1939 to house enemy officers who merited special supervision - but whose history can be traced back to 928 from a Christian Settlement. Initially poorly run after the invasion of Poland - Eggers, the officer in charge of security at Colditz turned it into a fortress of floodlights, sheer drops, barbed wire and many sentries. Morning parades took place to monitor prisoners, fingerprints and identity cards as well.
As for the prisoners, escapers were often loners, obsessed with finding their way back home and highly protective of their plans. As the war went on, and different nationalities were captured (Brits, Dutch and French being the most prominent) plans to escape often overlapped creating rebellion, although this was later negated by the officer of a particular regiment being the liaison for all plans, thus preventing overlap. Bribing guards would happen, who if found were often shot. Around 100 prisoners successfully escaped, mainly to Switzerland, which was neutral.
Conditions were good for most of the war, with entertainment permitted (privileges that the Germans hoped would entice prisoners not to escape). However, as the war ended, food shortages became severe and the Red Cross had to send supplies. Saluting wars took place, which the prisoners won (the Geneva convention said POW of rank were to be saluted to by their captors) while the Germans applied some nasty tricks to try and assassinate prisoners, such as encouraging them to walk near the barb wire and then shooting them. Colditz was captured by the Americans in April 1945.
