The Battle of Unsan (Korean: 운산전투; Hanja: 雲山戰鬪; RR: Unsan jeontu; MR: Unsan chŏnt'u), also known as the Battle of Yunshan (Chinese: 云山战斗; pinyin: Yúnshān zhàndòu), was a series of engagements of the Korean War that took place from 25 October to 4 November 1950 near Unsan, North Pyongan province in present-day North Korea. As part of the People's Republic of China's First Phase Campaign, the People's Volunteer Army (PVA) repeatedly attacked the Republic of Korea Army's (ROK) 1st Infantry Division near Unsan beginning on 25 October, to surprise the advancing United Nations Command (UNC). The United States' (US) 8th Cavalry Regiment was encircled on 1–2 November and broke out with the loss of most of its heavy equipment.
