On 22 June 1941, Hitler's Wehrmacht invades the Soviet Union. Without declaring war, more than 3 million soldiers cross the borders. The invasion had been carefully planned under the code name »Barbarossa«. For Hitler, the campaign is also a battle of two worldviews. At the end of 1941, rain and snow stop the advance. Even a new offensive in 1942 brought no resounding success.
