More than 100 million soldiers took part in WWII, but not all of them were fighting with guns. There was obviously a lot of administration and infrastructure to deal with, there were codebreakers and spies, and there were even some who engaged in secret deception to trick the enemy. A look in, not ghosts, but rather the Ghost Army, a dirty tricks tactical deception unit the Allies deployed in Europe near the end of the war to fool Axis commanders. Because, as the saying goes, all's fair in love and war. These are also really interesting stories. And you might consider them to have been, in fact, conspiracies, ones that were successful, by and large.
