In the Battle of the Bowling Alley (August 12–25, 1950), United Nations (UN) forces defeated North Korean (NK) forces early in the Korean War near the city of Taegu, South Korea. The battle took place in a narrow valley, dubbed the "Bowling Alley", which was north of Taegu. It followed a week of fighting between the North Korean People's Army 13th Division and the Republic of Korea Army's (ROK) 1st Division along the latter's last defensible line in the hills north of the city. Reinforcements, including the US Army's 27th and 23rd Infantry Regiments were committed to bolster the South Koreans' defenses. This battle and several others were smaller engagements of the Battle of Pusan Perimeter.
