The Battle of Yongdong was an engagement between United States and North Korean forces early in the Korean War. It occurred on July 22–25, 1950, in the village of Yongdong in southern South Korea. The newly arrived US Army 1st Cavalry Division was ordered there to cover the retreat of the US 24th Infantry Division after the Battle of Taejon. The 1st Cavalry Division soldiers, however, were untried in combat, and the North Korean Korean People's Army's (KPA) 3rd Division was able to outmaneuver them and force them back. Though the Americans lost the town, their artillery inflicted substantial casualties on the North Koreans and delayed them for several crucial days, allowing the United Nations Command time to set up the Pusan Perimeter.
