Giles Milton guides us round the critical locations in Normandy where the D-Day invasion proved successful on June 6th 1944. From the gliders who silently went behind enemy lines to paratroopers who ambushed vital German generals to soldiers who ran the gauntlet of machine gun fire and mortar fire on the beaches. We hear from local experts as well as 100 year old veteran Trooper William Gladden who was part of the airborne assault which captured the vital Normandy bridges during the might that helped win D-Day.
