Just Plain Wargames: Demyansk Pocket

From Pacific Rim Publishing:

Demyansk Pocket, is an Operational level wargame depicting the Soviet offensives in late 1941/early 1942 attempting to pinch off and destroy the German units occupying the Demyansk Pocket south of Leningrad. 126,000 Germans spent 47 days surrounded by the Russian Army and General Winter. The Germans began their attack to relieve the pocket four hours before the Soviets planned to start their attack to crush it.

Both sides must attack in some places and defend in others at the same time.
