"D-Day is one of history's greatest and most unbelievable military and human triumphs. Though the full campaign lasted just over a month, the surprise landing of over 150,000 Allied troops on the morning of June 6, 1944, is understood to be the moment that turned the tide for the Allied forces and ultimately led to the defeat of the Axis powers in World War II. Now, a new book from bestselling author and historian Garrett M. Graff explores the full impact of this world-changing event-from the secret creation of landing plans by top government and military officials and organization of troops, to the moment the boat doors opened to reveal the beach where men fought for their lives and the future of the free world." -- Publisher.
