How They Lie:
Proof of our Enemies’ Malicious Propaganda
by Ernst Herbert Lehmann
Background: This pamphlet was published in 1940 with the goal of preparing Germans to deal with Allied propaganda. The plan was to “inoculate” Germans so that they would disbelieve claims of German atrocities. It has 40 pages, and will take you a while to work through. The Nibelungen-Verlag had close ties to the SS.
