Simple Sabotage Field Manual

This Simple Sabotage Field Manual, a genuine guide from the Second World War, states that its purpose is to "e;characterize simple sabotage, to outline its possible effects, and to present suggestions for inciting and executing it."e; Among the other fine pieces of advice in this handy volume, one is encouraged to "e;switch address labels on enemy baggage"e;, "e;let cutting tools grow dull"e;, "e;forget to provide paper in toilets"e;, and "e;change sign posts at intersections and forks; the enemy will go the wrong way and it may be miles before he discovers his mistakes."e;
