The book describes the Red Army’s operations during the winter campaign of 1941/42 on the Soviet-German front, as well as the German command’s counter-moves aimed at eliminating the penetration in the defenses of three army groups. An analysis is presented of the overall plan of the Soviet winter offensive and the objective results of the exchange of blows across the entire front—from Lake Ladoga to the Black Sea. The Red Army’s offensives and the Wehrmacht’s counterattacks near Moscow, Kharkiv, and Demyansk; the attempt to break the siege of Leningrad and the struggle for Crimea—these events are described at a modern level, based on declassified documents and a wide range of foreign sources. Before us appears the history of operations, the role played by people and equipment in them—maximally cleared of political propaganda of any kind.
