Whose Plan Was D Day?

On June 6, 1944, Supreme Allied Commander General Dwight D. Eisenhower gives the go-ahead for the largest amphibious military operation in history: Operation Overlord, the Allied invasion

of northern France, commonly known as D-Day. By daybreak, 18,000 British and American parachutists were already on the ground.

Who came up with the plan for D-Day?

However, the next month, Roosevelt sent two of his top advisors, General George Marshall and Harry Hopkins, to London to meet with Churchill. They proposed “Operation Sledgehammer,” a plan to seize ports along France's northwest coast and then conduct a major invasion in the spring of 1943.

When did planning for D-Day begin?

Although limited planning for an invasion of Europe began soon after the evacuation of Dunkirk in 1940, detailed preparations for Operation 'Overlord' did not begin until after the Tehran Conference in late 1943.
