The sixth of June 1944 marked the start of the greatest amphibious operation ever attempted, as Allied forces united in a highly co-ordinated campaign to secure a foothold on European soil, free the occupied countries and eventually to invade Germany.

In graphic detail the story of that momentous day is related - from the immense initial preparations to the actual landings, through the bitter battle for Normandy, to the final triumphant liberation of Europe.
