Biography

Douglas MacArthur commanded UN forces in Korea from the war's opening days until his dramatic dismissal by President Truman in April 1951. A legendary figure from World War II, MacArthur engineered the brilliant Inchon landing that reversed the war's fortunes, then overreached by driving to the Yalu River despite clear warnings of Chinese intervention. His public challenge to Truman's limited-war strategy — advocating attacks on China and even use of nuclear weapons — forced Truman to relieve him, establishing the critical precedent of civilian control over military commanders in democratic society.

Key Battles

Battle of the Pusan Perimeter

UN / South Korea victory

August 4 – September 15, 1950 · 130,000 total casualties

The Pusan Perimeter was the last stand that prevented North Korean conquest of the entire peninsula. The successful defense preserved a foothold for the dramatic Inchon counteroffensive and demonstrated the resilience of combined UN forces under extreme pressure.

Battle of Inchon

UN / South Korea victory

September 15–19, 1950 · 14,232 total casualties

Inchon was one of the most audacious and successful amphibious operations in military history. It instantly reversed the strategic situation, cutting off North Korean forces besieging Pusan and forcing them into a chaotic retreat. MacArthur's gamble vindicated his unconventional operational genius.

Liberation of Seoul

UN / South Korea victory

September 25–28, 1950 · 17,500 total casualties

The recapture of Seoul was both a military and symbolic achievement, restoring the South Korean government to its capital and demonstrating the dramatic reversal of fortune achieved through the Inchon operation. It broke North Korean morale and accelerated the collapse of their forces in the south.

Battle of Unsan (Chinese Intervention)

North Korea / China victory

November 1–2, 1950 · 3,500 total casualties

Unsan was the first major engagement between US and Chinese forces and a dramatic warning that was largely ignored. MacArthur dismissed the Chinese presence as token. The engagement previewed Chinese tactical methods — mass night infiltration, encirclement, and human wave assaults — that would soon devastate UN forces across the entire front.
