Seventy-five years ago, on the 6th of June 1944, the biggest military landings in history took place. You might think that by now there would be little more to discover about the invasion. But, after 20 years of research Dominique Forget, one of the world’s foremost experts in World War II archives, has identified nearly 100 hours of unpublished film archives, including 20 hours of the Battle of Normandy. Punctuated by in-depth explanations from leading experts, including Sir Anthony Beevor, the number one bestselling historian in Britain, The Battle of Normandy: 85 Days in Hell (June 6^th, 9pm)  recounts the military strategic decisions that allowed this battle to take place, and how Normandy, France and Europe regained their freedom.
