This fast paced episode of "Battlefield" chronicles the titanic war in the east, that eventually decided World War II in Europe. Despite numerous warnings from the Communist spy networks: the Lucy Spy-Ring the Red Orchestra Richard Sorge, and pleadings from Churchill and FDR, through ultra decrypts, Stalin discounted all invasion warnings. Stalin felt that all these alarming reports was actually an attempt to divide agreements between the Soviet Union and Nazi Germany, by the British and Americans. The Soviet Union shipped supplies ahead of schedule to Nazi Germany. The people of the Soviet Union and Stalin were completely dumbfounded when the Germans invaded the Soviet Union on June 22, 1941. Three German Army Groups attacked into North, Central and the Southern Soviet Union.
