The Battle of Pork Chop Hill comprised a pair of related Korean War battles fought between United Nations forces and the Chinese and North Korean armies from April through July 1953.
Fought while the UN and the Chinese and North Koreans were negotiating the Korean Armistice Agreement, these battles were controversial because of the many soldiers killed for terrain of no strategic or tactical value—although the Chinese lost many times the number of US soldiers killed and wounded.
UN forces won the first battle (depicted in the 1959 movie Pork Chop Hill) when the Chinese broke contact and withdrew after two days of fighting. The second battle was bitterly contested for five days before UN forces withdrew behind the main battle line.
