The Korean War: The UN Offensive

The UN Offensive 16 September – 2 November 1950. Following a surprise North Korean attack on 25 June 1950, Lt. Gen. Walton H. Walker’s Eighth Army fought desperate battles to halt the invasion before finally establishing a defensive line to protect the vital port city of Pusan on the southeast coast of the Korean peninsula. By August the Pusan Perimeter stretched about one hundred miles north along the west bank of the Naktong River, west of Pusan, and, after turning east near Naktong-ni, about fifty miles to the coast above P’ohang-dong. As the fighting ensued along the perimeter, more American forces entered Korea to stem the Communist tide.
