President Eisenhower and Winston Churchill
General Dwight David Eisenhower of the US ARMY was the Allied Commander for the Normandy Invasion. He had all the allied forces under his command for that ( not the Pacific Theater forces obviously ) and his local officers in direct charge were General Montgomery in command of British and Canadian Forces and Gen Omar Bradley, US Army , in charge of American Forces.
The buck stopped with Fleet Admiral Chester Nimitz, whose WWII titles included the dual command of Commander in Chief, US Pacific Fleet for U.S. naval forces and Commander in Chief, Pacific Ocean Areas for U.S. and Allied air, land, and sea forces.
There were three theaters in the war against Japan - the Central Pacific, the Southwest Pacific, and the China-Burma-India Theaters of Operations. The Pacific was divided largely to carve out a command for General Douglas MacArthur, who had enormous prestige and was a former Chief of Staff (commanding general) of the US Army. When MacArthur escaped from the Philippines the Southwest Pacific was created to make an appropriate command for him. He was based in Australia at first, and fought his way through New Guinea and neighboring island chains, and the Philippines. The Central Pacific Theater was under the command of US Admiral Chester Nimitz, who also commanded the US Pacific Fleet, and was based in Hawaii. Admiral Lord Louis Mountbatten commanded the CBI. He was an uncle of Prince Philip, the husband of Queen Elizabeth II. Mountbatten was murdered by the IRA in 1979. Though Eisenhower was the "Supreme Allied Commander" in the European Theater of Operations, there was also a Mediterranean Theater of Operations, which directed the fighting in Italy. Eisenhower commanded the MTO before moving to England to ready for the invasion of France, after which the MTO command passed to British General Harold Alexander. There was no single supreme commander of allied forces in the Pacific Theater. General MacArthur was the commander for the South West Pacific Area, while Admiral Nimitz was commander of the Pacific Ocean Area. See the related question for more information.
US Army General Eisenhower was the supreme allied commander in the ETO (European Theater of Operations). US Army General MacArthur was the supreme allied commander in the Southwest Pacific of the PTO; US Navy Admiral Nimitz was the supreme allied commander in the remaining portions of the PTO (Pacific Theater of Operations). US Army General Stillwell was the supreme allied commander in the CBI (China, Burma, India Theater of Operations).
The Pacific Theater of Operations was so large it required two US/Allied supreme commanders: Navy-Admiral Nimitz/Army-General MacArthur.
In the Pacific Theater of Operations, America and its allies fought the Empire of Japan.
The Allies divided the world into Theaters of Operations, of which there were two in the Pacific, the Central Pacific Theater and the Southwest Pacific Theater. There was also a China-Burma-India Theater. US Army General Douglas MacArthur was commander of the Southwest Pacific Theater. US Navy Admiral Chester Nimitz commanded the Central Pacific, and he was also commander of the US Pacific Fleet. Nimitz usually had the six divisions of US Marines, and Army troops as well under his command, plus US Army Air Force units. British General Lord Louis Mountbatten commanded the China-Burma-India Theater.
Union Captain Samuel Du Pont was in charge of naval operations and General Thomas W. Sherman was in charge of army operations in this joint armed forces capture of Port Royal.
General Omar Bradley was in charge of the US landings. General Bernard Montgomery was in charge of the British and Canadian landings.
