 FACT: The airman Bernhart, when talking with the new proprietors of  the Isaaks photographic shop complains that if he is seen going  into the (Jewish) shop, he would be posted to the eastern front. The  eastern front, as the war with the Soviet Union came to be generally  known (as an unpleasant and dangerous theatre to be posted to), did  not exist until the following summer, with Operation Barbarossa.
