Breakthrough (1979)

Starting in late May 1944, during the German retreat on the Eastern Front, Captain Stransky (Helmut Griem) orders Sergeant Steiner (Richard Burton) to blow up a railway tunnel to prevent Russian forces from using it. Steiner's platoon fails in its mission by coming up against a Russian tank. Steiner then takes a furlough to Paris just as the Allies launch their invasion of Normandy.
