Battle of Kapyong

The Battle of Kapyong (Korean: 가평전투) (22–25 April 1951), also known as the Battle of Jiaping (Chinese: 加平战斗; pinyin: Jiā Píng Zhàn Dòu), was fought during the Korean War between United Nations (UN) forces—primarily Australian and Canadian—and the Chinese communist People's Volunteer Army. The fighting occurred during the Chinese Spring Offensive and saw the 27th British Commonwealth Brigade establish blocking positions in the Kapyong Valley, on a key route south to the capital, Seoul. The two forward battalions—3rd Battalion, Royal Australian Regiment (3 RAR) and 2nd Battalion, Princess Patricia's Canadian Light Infantry (2 PPCLI)—occupied positions astride the valley and hastily developed defences. As thousands of South Korean soldiers began to withdraw through the valley, the Chinese infiltrated the brigade position under the cover of darkness, and assaulted the Australians on Hill 504 during the evening and into the following day.
