Smithsonian Channel - D-Day: The True Story of Omaha (2007)

On the 64th anniversary of the D-Day landings, a television documentary shows just how close America came to losing one of the most important – and bloodiest – battles in its history.
History remembers D-Day, the greatest amphibious invasion ever attempted, as a great victory by U.S. forces, which were launched across the English Channel from the southern shore of England. The Normandy Invasion is a battle we thought we knew. History records that within hours, 2,000 men were killed. But new research has found that in reality, the casualty figures were more than double that.
