On This Day - What happened 10 June 1953 AD in undefined

Outpost Harry was a remote Korean War outpost located on a tiny hilltop in what was commonly referred to as the "Iron Triangle" on the Korean Peninsula. This was an area approximately 60 miles (100 km) northeast of Seoul and was the most direct route to the South Korean capital.

The Battle of Kumsong, also known as the Jincheng Campaign , was one of the last battles of the Korean War. During the ceasefire negotiations seeking to end the Korean War, the United Nations Command (UNC) and Chinese and North Korean forces were unable to agree on the issue of prisoner repatriation. South Korean President Syngman Rhee, who refused to sign the armistice, released 27,000 North Korean prisoners who refused repatriation. This action caused an outrage among the Chinese and North Korean commands and threatened to derail the ongoing negotiations. As a result, the Chinese decided to launch an offensive aimed at the Kumsong salient. This would be the last large-scale Chinese offensive of the war, scoring a victory over the UNC forces.
