The rise of the Red Army, mobilization of Soviet production, the Siege of Leningrad, the Soviet partisans, and the Battle of Kursk.
Bent on fulfilling Hilter's policy of colonizing Russia, German forces invade subjecting inhabitants of occupied lands to servitude or death.

After German forces fail to break Lenigrade or to capture Kursk and the surrounding Russian forces Russia goes on the offensive with its military production at full capacity.—David Foss
