Operation Ripper, also known as the Fourth Battle of Seoul, was a United Nations military operation conceived by the commander US Eighth Army, General Matthew Ridgway, during the Korean War. The operation was intended to destroy as much as possible of the Chinese communist People's Volunteer Army and North Korean military around Seoul and the towns of Hongch'on, 50 miles (80 km) east of Seoul, and Ch'unch'on, 15 miles (24 km) further south. The operation also aimed to bring UN troops to the 38th parallel. It followed upon the heels of Operation Killer, an eight-day UN offensive that concluded February 28, to push Communist forces north of the Han River. The operation was launched on March 6, 1951 with the US I Corps and IX Corps on the west near Seoul and Hoengsong and US X Corps and ROK III Corps in the east, to reach "Line Idaho", an arc with its apex just south of the 38th Parallel in South Korea.
