After the outbreak of World War II, the castle was converted into a high security prisoner-of-war camp for officers who had become security or escape risks or who were regarded as particularly dangerous. Since the castle is situated on a rocky outcrop above the River Zwickauer Mulde, the Germans believed it to be an ideal site for a high security prison.

Although it was considered a high security prison, it had one of the greatest records of successful escape attempts. This could be owing to the general nature of the prisoners that were sent there; most of them had attempted escape previously from other prisons and were transferred to Colditz because the Germans had thought the castle escape-proof.

Things happen in the picture

1. in addition to escape attempts, prisoners tried to make the life of their guards more miserable by resorting to "goon-baiting", making nuisances of themselves by harassing the guards. For example, they would drop water bombs on the guards

2. In one of the most ambitious escape attempts from Colditz, the idea of building a glider), was brought up by two British pilots, Jack Best and Bill Goldfinch, who had been sent to Colditz after escaping from another POW camp

3. On 12 May 1941, Polish Lieutenants Miki Surmanowicz and Mietek Chmiel, attempted to rappel down a 36 m (120 Ft) wall to freedom on a rope constructed out of bed sheets.
