Imagine sitting in a classroom in the English countryside miles from anywhere, alongside dozens of fellow students, each of you expecting to be parachuted into Occupied France for a daring mission against Hitler's forces. What were you taught? What text books did they give you, and what homework and exams were you expected to pass? This book is the classroom dossier that Allied special operations agents were supplied with in World War II. Packed with illustrations—for everything from underwater breathing gear to explosives disguised as flashlights or dead rats—the book describes techniques in camouflage, setting up communications, concealing weapons caches, and constructing booby traps.
