What was Camp X?

Lt. Col. Bill Brooker was not the first commandant of Camp X (Arthur Terence Roper-Caldbeck was), but he was the most influential. He enforced a strict military code of discipline and brought with him a wealth of experience in training agents at SOE schools in the U.K. Brooker knew his agents had to be ready for anything, so he engaged in unorthodox training methods, like interrupting students' classroom sessions with mock gun battles then making them recall facts about the incident, such as the number of shots fired or what the assailants were wearing. Students undertook mock missions, infiltrating a guarded house or sneaking through the damp Ontario night.
