His division held the vital Tabu-dong corridor during the Pusan Perimeter battles, preventing the fall of Taegu. Paik advanced rapidly, commanding a corps and then becoming Chief of Staff of the ROK Army. He earned the deep respect of American commanders for his tactical skill, personal courage, and ability to inspire his soldiers in the most desperate circumstances.

Key Battles
Battle of the Pusan Perimeter
UN / South Korea victoryAugust 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.
Liberation of Seoul
UN / South Korea victorySeptember 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 victoryNovember 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.
