The Iron Triangle
As UN forces fought their way north in 1951 Chinese resistance increased and the advance slowed. US Army units captured the towns of Chorwon to the west and Kumhwa to the east and raided north toward Pyonggang, not to be confused with the North Korean capital Pyongyang further north. Hopes for a quick armistice faded and UN and Communist forces entrenched. A newspaperman called this area the Iron Triangle and the name stuck. The Iron Triangle section of the UN line was mainly manned by US Army troops since they required more supply than the Marine and ROK forces and a rail line was conveniently nearby.
