The UN troops, consisting mostly of forces from the Republic of Korea (ROK), United States and United Kingdom mounted a last stand around the perimeter, fighting off repeated North Korean attacks for six weeks as they were engaged around the cities of Taegu, Masan, and P'ohang, and the Naktong River.
Pasukan PBB, yang kebanyakan terdiri dari Republik Korea (ROK), Amerika Serikat dan Persemakmuran Britania, melakukan pendirian terakhir di sekitaran perimeter tersebut, menangkit serangan-serangan Korea Utara berulang selama enam pekan karena mereka merenggut sekitaran kota Taegu, Masan, dan P'ohang, dan Sungai Naktong.
