MTO - Egypt: At the 2nd Cairo Conference, President Roosevelt decides on General Dwight D Eisenhower as the Supreme Allied Commander for Operation OVERLORD, the invasion of western Europe.
General Dwight D Eisenhower
After the Japanese attack on Pearl Harbor, Eisenhower was assigned to the General Staff in Washington, where he served until June 1942 with responsibility for creating the major war plans to defeat Japan and Germany. Chief of Staff General George C Marshall spotted talent and promoted Ike accordingly.
As Supreme Allied Commander in Europe, Eisenhower's first struggles were with Allied leaders and officers on matters vital to the success of the Normandy invasion. He insisted that the British give him exclusive command over all strategic air forces to facilitate Overlord, to the point of threatening to resign unless Churchill relented, which he did.
Although Ike was very skilled at the frustrating task of dealing diplomatically with the egos that surrounded him, he knew that the only way things would get done was by being the "benevolent dictator" needed to be victorious, which could only happen with a single person calling the shots.
