Their heroism helped change the course of the second world war, and now some of the surviving D-Day veterans have been immortalised in a series of photographs taken at the places where they fought.
The collection of pictures, titled 'Last of the Liberators', was unveiled at the Imperial War Museum at Duxford in Cambridgeshire today to mark the 70th anniversary of the Normandy Landings.
Nick Archdale was with The Parachute Regiment on D-Day.
He was dropped behind enemy lines and fought to take a bridge key for the Allied advance.
And it's by that very wall that Nick is photographed.
He is one of 15 veterans taken back to be pictured in a place that has personal significance to their D-Day story.
Geoff Pattinson was also parachuted into occupied France. Out on patrol he came face to face with German soldiers who started shooting.
They ran into the stable for cover, but Geoff was shot and injured.
The photographer who thought the project up has now written a book about the veterans and their stories.
Geoff and Nick will be returning to Normandy for the 70th anniversary celebrations.
Although it's painful, they know it's something they must do.
Some of the stories at least, will now be immortalised in these pictures.
