Today it is easy to see D Day as inevitable a straightforward victory against a German army that was already all but defeated. This film explodes that myth. It charts the careful planning of the campaign, the development of specialised equipment needed for the amphibious landing. It reveals the deception plan that wrong footed Hitler. It shows how the Americans were very nearly driven off Omaha beach. If that had happened, the whole operation might have failed. The film ends with the Liberation of Paris, as the Free French forces led by Charles de Gaulle matched down the streets of the capital.
