The Battle of the Pusan Perimeter, known in Korean as the Battle of the Naktong River Defense Line (Korean: 낙동강 방어선 전투), was a large-scale battle between United Nations Command (UN) and North Korean forces lasting from August 4 to September 18, 1950. It was one of the first major engagements of the Korean War. An army of 140,000 UN troops, having been pushed south to the brink of defeat, were rallied to make a final stand against the invading Korean People's Army (KPA), 98,000 men strong. UN forces, having been repeatedly defeated by the advancing KPA, were forced back to the "Pusan Perimeter", a 140-mile (230 km) defense line around an area on the southeastern tip of South Korea that included the port of Busan (then spelled Pusan). The UN troops, consisting mostly of forces from the Republic of Korea Army (ROKA), United States, and United Kingdom, mounted a last stand around the perimeter, fighting off repeated KPA attacks for six weeks as they were engaged around the cities of Taegu, Masan, and Pohang and the Naktong River.
