One night, a German guard went to the lavatory in the
northeast end of the Kommandantur, or German headquarters building. While in
the bathroom, which backed onto one of the British prisoners' rooms, the guard
heard a scratching noise. Informed, Colditz security personnel lay in wait.
This night, two British officers dressed as civilians suddenly broke through
the wall behind the john and walked out of the bathroom. "This way, please,
gentlemen!" their welcoming committee announced. In all, ten prisoners came
through the hole before the Germans decided to end the sport.
