Part One
Is the story of Germany's Wehrmacht against the Russian Red Army. The Russians appeared to be seriously overmatched, but history would prove that they were ready for battle when it counted.
Part Two
Provides an unflinching glimpse of the desperation and horrors of war during one of World War II's most ferocious and bloody battles. Hitler's Sixth Army held Stalingrad alone -- cut off from supplies by hundreds of miles of Russian-held territory. After a brutal battle 110,000 German soldiers were captured -- only 5,000 lived to see Germany again!
