In the early hours of Tuesday, 6th June 1944, three divisions of paratrooper and glider forces descended on Normandy. Already assembling offshore was the largest seaborne invasion fleet in the history of the world, ready to unleash over 130,000 troops against Hitler's Atlantic Wall. More than 7,000 aircraft filled the skies. D-Day - and the liberation of Europe - had begun. Facing them were massive concrete strongpoints bristling with Nazi artillery, machine gun nests and pill boxes, untold miles of barbed wire, vast minefields and underwater obstructions designed to rip fragile landing craft apart. For the troops heading onto the beaches and the paratroopers fighting to survive just a few miles inland, it would truly be "The Longest Day.' Featuring an exceptional selection of historic photographs as well as detailed battle maps, D-DAY provides a gripping account of the airborne actions and the beach assaults as well as revealing the top secret war fought by the Allies in the build up to the invasion.
