CRISIS ALONG THE PUSAN PERIMETER

Crisis along the Pusan Perimeter

By August 31st, 1950, United States and South Korean troops clung to a shrinking defensive line around the port of Pusan, the last major foothold on the Korean Peninsula. That night, North Korean forces launched a renewed offensive, striking hard along the Naktong River and probing for gaps in the perimeter. American divisions, some newly arrived and still adjusting to the terrain and climate, scrambled to plug penetrations with artillery, tanks, and hastily assembled reserve companies. The fighting was close, confused, and often conducted in darkness, with units falling back to new positions and then counterattacking. Holding the Pusan Perimeter through this crisis bought time for planners to prepare the bold amphibious landing at Inchon that would soon change the war’s momentum. The stand in late August showed how fragile and yet how vital a perimeter defense could be in the early Cold War.
