During the early days of World War II, the Nazis stormed through country after country in Europe, propelled not only by Germany's military might but also by the power of its propaganda. In one classic psywar terror operation, just before Hitler's troops invaded France they showered the country with leaf-shaped paper leaflets bearing this message:
"Autumn, the leaves are falling.
We will fall like them....
Next spring nobody will remember either
the dead leaves or the dead soldiers."
