The First Battle of Maryang-san, also known as the Defensive Battle of Maliangshan, was fought during the Korean War between United Nations Command (UN) forces—primarily Australian, British and Canadian—and the Chinese People's Volunteer Army (PVA). The fighting occurred during a limited UN offensive by US I Corps, codenamed Operation Commando. This offensive ultimately pushed the PVA back from the Imjin River to the Jamestown Line and destroyed elements of four PVA armies following heavy fighting. The much smaller battle at Maryang-san took place over a five-day period, and saw the 1st Commonwealth Division dislodge a numerically superior PVA force from the tactically important Kowang-san, Hill 187, and Maryang-san features.
