Moscow ’41 is the first volume in the Barbarossa Trilogy with the other two games being Leningrad ’41 and Kiev ’41). Moscow ’41 is a light/medium wargame covering the German Army Group Centre offensive aimed to seize Moscow, after having successfully defeated several Soviet armies in the great encirclement battles at the frontier and established two bridgeheads on the Dnieper.

Although based on a historical event, the two players have free will to modify the course of the operation, with the Germans trying to achieve a decisive victory before the winter comes, and the Soviets playing a fighting withdrawal, until ready to strike a decisive blow.
