In a massive armada of thousands of ships, 3,000,000 allied troops land at Three Beaches in Normandy, France--one of the most incredibly co-ordinated military operations ever. Scaling the impregnable "Atlantic Wall," constructed by the Germans, turns out to be one of the most difficult and constly battles of World War II.
