On 11 April 1951, President Harry S. Truman removed General Douglas MacArthur from command after MacArthur publicly criticized policies of the administration. MacArthur had been a celebrated World War II hero and was leading United Nations forces in the Korean War at the time, which is why the decision remains debated in discussions of civilian and military relations. He previously commanded Allied forces in the Southwest Pacific and later led the occupation of Japan, where he gained unusually broad influence and political experience. In the Korean War, he led UN defenses against North Korea, launched the successful amphibious assault at Inchon, but was later forced to retreat when China’s forces defeated his advance. Although the military situation stabilized by April 1951, Truman acted after MacArthur publicly challenged government policy, and the Senate committees later concluded the move was within the president’s constitutional authority. The inquiry also noted the decision was a shock to national pride, and it reflected Truman’s insistence that the president—not the general—must be the top civilian authority in military affairs. Harry S. Truman became U.S. president in 1945 after Franklin D. Roosevelt died, then won an unexpected full term in 1948. Though he had no college degree and stopped formal studies early, he was well read and served in World War I artillery, later reaching colonel in the reserves; he also worked with National Guard military aides rather than career soldiers. During the 1949 Revolt of the Admirals, senior naval leaders criticized cuts to naval aviation and amphibious forces, leading to the replacement of the Chief of Naval Operations, and Omar Bradley later doubted another large amphibious operation would happen. General of the Army Douglas MacArthur was the Army’s top-ranking general, graduating first in his West Point class in 1903 and earning a distinguished World War I record. In World War II he became a national hero for his Medal of Honor actions in the Philippines and later led Allied campaigns, then oversaw the occupation of Japan and helped shape Japan’s post-war transformation. By 1950, as Japan’s occupation wound down, he stayed in the region as Commander-in-Chief Far East, but major defense budget cuts sharply reduced troops and left widespread equipment shortages. Far East Command responded by refurbishing abandoned war supplies and shifting more time toward training for combat. North Korea invaded South Korea on 25 June 1950, starting the Korean War, and MacArthur acted quickly by ordering ammunition to be shipped to Pusan. Truman approved expanding air and naval attacks, later authorizing ground forces after MacArthur reported the situation was worsening. In July, MacArthur was made commander of the UN forces, though nuclear weapons were discussed and rejected, and at one point nuclear-capable bombers were sent to Guam as a deterrent. Truman also faced questions about whether UN forces would cross the 38th parallel, while advisors disagreed over whether Resolution 83 legally supported invading North Korea and worried about possible Soviet or Chinese involvement if UN troops got too close to their borders. MacArthur’s amphibious plans were delayed as the fighting situation in the south worsened, forcing the 1st Cavalry Division to defend the Pusan Perimeter. He later pushed forward with a landing at Inchon despite fierce objections from Navy and Marine leaders about dangerous tides, mudflats, and narrow channels, telling Washington he would “crush them.” After Inchon’s success, Truman endorsed UN-aligned plans that allowed action north of the 38th parallel if China intervened, though MacArthur wasn’t fully informed until later; meanwhile, the Chiefs grew hesitant to challenge MacArthur’s decisions, and UN permission to invade was eventually supported by a resolution in October.
