Leningrad

Leningrad recreates one of the most crucial campaigns of the Second World War, the northern wing of Operation Barbarossa in which German forces drive along the Baltic coast to take Leningrad and trap the Soviet fleet.
The German military was at its operational peak: panzer divisions provided the striking power, the sturdy infantry divisions followed behind to hold the line and secure conquered territory, while overhead the Luftwaffe provided combat support and attacked marching enemy columns.
Division-for-division the Soviets were outclassed, but they had plenty of ground to give to gain time for their massive reserves to reach the front.
Historically the Soviets just managed to keep the Germans out of Leningrad, but it might easily have turned out differently.
