In commemoration of the 60th anniversary of D-Day, this program is the story of how it all came together: two years of planning, close to 7,000 ships, almost 160,000 soldiers and fighting men from three nations, backed by 17,000 paratroopers and an aerial umbrella of 3,000 planes. The film shows step by step how the Allies achieved victory on June 6, 1944. Where the invaders failed, the film investigates how and why this happened.
