Who was the supreme commander of D Day The Normandy Invasion in WWII?

Dwight D. Eisenhower

Following his arrival in London, Major General Dwight D. Eisenhower takes command of U.S. forces in Europe. After proving himself on the battlefields of North Africa and Italy in 1942 and 1943, Eisenhower was appointed supreme commander of Operation Overlord–the Allied invasion of northwestern Europe.

In January 1944 the Allies appointed an invasion commander, Dwight D. Eisenhower, and placed him within a flexible, fully binational Anglo-American chain of command. Bernard Law Montgomery Rommel’s desert opponent in North Africa was nominated, under Eisenhower, as commander of the ground invasion forces. Walter Bedell Smith, an American, continued as Eisenhower’s chief of staff, but his other principal subordinates were British: Air Chief Marshal Arthur Tedder as his deputy, Admiral Bertram Ramsay as Naval Commander, and Air Chief Marshal Trafford Leigh-Mallory as head of the expeditionary air forces. A Free French delegate, Marie-Pierre Koenig, served as a liaison between SHAEF and the president of the French Committee of National Liberation, Charles de Gaulle. Omar Bradley was the most senior commander of American ground troops in Europe from the time of D-Day (June 1944) to the surrender of the Germans after the Battle of Berlin in May 1945.
