The Battle of Tannenberg Line, second to Stalingrad, the bloodiest conflict on the Eastern Front. Volunteer infantry battalions from Denmark, East Prussia, Flanders, Holland, Norway and Wallonia within the Waffen-SS fight off Soviet Army's thrust at Germany. Half of the SS infantry consists of local Estonian conscripts motivated to resist the looming Soviet re-occupation of their small country. Motivated until they meet their brothers in the Soviet Army. Estonian men, deported by Stalin in 1939, now brought out of Siberian labour camps and returning home in enemy uniforms.
