When The Sea Came Alive An Oral History Of D-Day Garrett M. Graff, D-Day is one of history's greatest and most unbelievable military and human triumphs. 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 allied forces and ultimately led to the defeat of the Axis powers in World War II. Now, a new book from Garrett M. Graff explores the full impact of this event-from the secret creation of landing plans to the moment the boat doors opened to reveal the beach where men fought for their lives and the future of the free world-and offers a fitting tribute to the men and women of the Greatest Generation.
