There was a sneaky little trick on the Mountbatten course. The idea was that after a couple of days evading, when you are tired and hungry, a "partisan" was to guide you to safety. Needless to say, he was a double agent, and led you into a trap. Supposedly, at the weekend a selected Army unit was told they were going to have a long weekend, starting from lunch on Friday. Mid-morning it was cancelled because the RAF wanted people to act as "enemy" for a course, and the weekend wouldn't start until lunch Saturday. Of course, when they captured us, their mood was far from warm, cuddly and welcoming.
