16 SEPTEMBER 1950 - BREAKOUT FROM THE PUSAN PERIMETER - #KoreanWar
Lieutenant General Walton Walker's Eight Army, reinforced by American and other United Nations (UN) units to begin a counter-offensive against the communist invaders. The ROK I and II Corps were positioned on the north side of the perimeter; the U.S. I Corps, composed of the 1st Cavalry Division, the 27th British Commonwealth Brigade, the 24th Infantry Division, and the 1st ROK Division, was on the Taegu front; and, the U.S. 2d and 25th Infantry Divisions and attached ROK units held positions along the Naktong River.
On 16 September, the Eighth Army attacked northward as the X Corps advanced southward from the beachhead at Inchon. Finding themselves between converging forces, the North Koreans feared being cut off and fled north while suffering heavy losses in men and materiel.
Late on 26 September, elements of the 7th Infantry Division of the X Corps and the 1st Cavalry Division of Eighth Army made contact just south of Suwon. Organized enemy resistance continued in the Eighth Army sector until the end of September as UN forces captured more than 100,000 enemy prisoners, while many North Korean units retreated through the eastern mountains.
By 30 September the NKPA had ceased to exist as an organized force below the 38th parallel, although die-hard remnants fought on as guerrillas, which continued to present a considerable threat to UN rear area security operations.
By the end of September, the Eighth Army was further reinforced by a battalion each of Philippine and Australian troops, and in early October, the U.S. 3d Infantry Division arrived in the Far East from the United States.
