It is commonly said that history is written by the victors, but the exact opposite occurred in the chronicling of the Eastern Front, particularly in the West. Soviet secrecy and unwillingness to acknowledge events that might discredit the regime led to them revealing little information, always heavily edited, leaving western historians to rely almost totally on German sources. While still valuable sources, they tended to be self-serving; German generals, in particular, tried to distance themselves and the Heer as a whole away from the Nazi Party, while at the same time blaming them for their defeat (individuals supporting these arguments are commonly called part of the 'Hitler Lost Us The War' group).
