D-Day was truly one of those days that changed the course of History. What was at stake was nothing less than the freedom of the western world. In a major two-part series, Dan Snow examines how two years of meticulous planning, espionage and the analysis of millions of three-dimensional aerial reconnaissance photographs shaped the planning for that day. D-Day The Last Heroes is also a powerful and compelling story of heroism and self-sacrifice and this is perhaps the last chance to hear the extraordinary first-hand testimonies of those who risked their lives to save the world from Nazi tyranny. With unprecedented access to thousands of top secret 3D spy photographs, compelling story telling, state of the art CGI, rare archive colour footage and dramatic reconstruction, Last Heroes of D-Day brings one day in June 1944, into sharp focus. Part One examines how two years of meticulous planning, espionage and aerial reconnaissance helped the Allied Forces gain a foothold in Northern France. Part Two tells the powerful and heroic stories of those who risked their lives on the beaches of Normandy, to save the world from Nazi Germany. Fascinating viewing full of inspirational stories and action scenes, this is a compelling account of D-DAY.
