It is September, 1943. The armies of the 3rd Reich occupy virtually the entire territory of Europe. The lands taken by the Germans spread from Brest, a town on the western brink of the continent, to the suburbs of Stalingrad. Numerous resistance groups operate in the occupied regions of Europe. Using the tactics of surprise attacks and the support from local people, they can effectively confront much larger, better-equipped and trained troops of the enemy.
