Korean War The Korean War (in South Korean Hangul: 한국전쟁 ; Hanja: 韓國戰爭 ; RR: "Hanguk Jeonjaeng " , "Korean War"; in North Korean Chosŏn'gŭl: 조국해방전쟁 ; Hancha: 祖國解放戰爭 ; MR: "Choguk haebang chǒnjaeng " , "Fatherland Liberation War"; 25 June 1950 – 27 July 1953) was a war between North Korea (with the support of China and the Soviet Union) and South Korea (with the principal support of the United States). The war began on 25 June 1950 when North Korea invaded South Korea. The United Nations, with the United States as the principal force, came to the aid of South Korea. China came to the aid of North Korea, and the Soviet Union also gave some assistance to the North.
First Battle of Maryang San The First Battle of Maryang San (3–8 October 1951), also known as the Defensive Battle of Maliangshan (), was fought during the Korean War between United Nations (UN) forces—primarily Australian and British—and the Chinese communist People's Volunteer Army. The fighting occurred during a limited UN offensive by US I Corps, codenamed Operation Commando. This offensive ultimately pushed the Chinese back from the Imjin River to the Jamestown Line and destroyed elements of four Chinese armies following heavy fighting. The much smaller battle at Maryang San took place over a five-day period, and saw the 3rd Battalion, Royal Australian Regiment (3 RAR) dislodge a numerically superior Chinese force from the tactically important Kowang-San (Hill 355) and Maryang San (Hill 317) features, in conjunction with other units of the 1st Commonwealth Division.
