Douglas MacArthur was an American five star general and Field Marshall of the Philippine Army. He was Chief of Staff of the United States Army during the 1930s and played a prominent role in the Pacific theater during World War II. He received the Medal of Honor for his service in the Philippines Campaign, which made him and his father Arthur MacArthur, Jr., the first father and son to be awarded the medal. He was one of only five men ever to rise to the rank of General of the Army in the US Army, and the only man ever to become a field marshal in the Philippine Army.
At the beginning of the Korean War, he was appointed commander of UN military forces in South Korea, while retaining his command of Allied forces in Japan. After driving the North Korean forces back over the 38th parallel, MacArthur received President Truman's permission to press into North Korea and advance all the way to the Yalu River—the border between North Korea and China—despite warnings that this might provoke Chinese intervention. When China did intervene, causing the UN forces to fall back, MacArthur pressed for permission to bomb Chinese bases in Manchuria. Truman refused and finally removed him from command in Apr., 1951.
On his return to the United States, MacArthur was given a hero's welcome and invited to address a joint session of Congress. Another attempt to nominate MacArthur for the presidency was unsuccessful in 1952. Retired from active service, he became an officer of a large business corporation.
