The German authorities used propaganda to control opinion among the populations of Germany and the conquered territories. Simultaneously, they conducted a masterful program of disinformation to the outside world. By carefully concealing their campaigns of persecution and murder, the Germans were able to limit interference from the international community as well as resistance from their targeted victims. Much of this work was conducted by little more than a strategic use of language. Deportation to concentration camps and death camps was called “relocation for the war effort,” while gas chambers typically had a sign which said “Bath House.” Communications from camps and ghettos were also carefully controlled. Prisoners were forced to write cheerful postcards, or, like Paula’s family, were instructed to pose in warm clothes for staged photographs. These tactics were very effective.
