When The Sea Came Alive

June 6, 1944-known to us all as D-Day – is one of history’s greatest and most unbelievable military triumphs. Though the full campaign lasted a little over two months, the surprise sunrise landing of more than 150,000 Allied troops on the beaches of occupied northern France is one of the most consequential days of the 20th century. It was the moment that turned the tide for the Allied forces and ultimately led to the defeat of the Axis powers in World War II, freeing Europe from the clutches of fascism and tragedy. In the decades since, countless stories of bravery, brotherhood, and sacrifice have made up and sustained our collective memory. Now, Pulitzer Prize finalist Garrett M. Graff, historian and author of The Only Plane in the Sky and Watergate, brings them all together in a one-of-a-kind oral history that explores this seminal event in vivid, heart-pounding detail.

The story begins in the opening months of the 1940s, as the Germany army tightens its grip around eastern and western Europe, seizing control of entire nations on the ground and bombarding others into submission by air. The United States, who has resolved to remain neutral, is forced to enter the conflict after an unexpected attack by the Japanese at Pearl Harbor. For the second time in fifty years, the world is at war, with the stakes higher than they’ve ever been before.

Then, in 1943, as morale and resources start to wane, Allied leaders ?Franklin D. Roosevelt and Winston Churchill meet in Casablanca to discuss a new plan for victory: a coordinated invasion of occupied France, led by General Dwight D. Eisenhower. Failure, it is understood, is not an option. Over the next eighteen months, under the codename OVERLORD and a deep veil of secrecy, the large-scale action is organized, mobilizing soldiers across Europe by land, sea, and sky. And when the day comes, it is unlike anything the world has ever seen.

These moments and more are seen in real time, through the eyes of those who experienced them: the children and citizens whose towns are suddenly populated by troops training on the coast of England; the COSSAC planners bent over maps and meteorological reports, making sure that every scenario is planned through; the airmen and paratroopers glancing out the sides of their planes, ready to jump into occupied territory and fight; the intelligence operatives seeding disinformation with the enemy so that they don’t catch on to the Allied plan; the army correspondents and journalis
