The Battle of Ka-san was an engagement between United Nations Command (UN) and North Korean forces early in the Korean War from September 1 to September 15, 1950, in the vicinity of Ka-san (Ka mountain), Chilgok County in South Korea. It was a part of the Battle of Pusan Perimeter, and was one of several large engagements fought simultaneously. The battle ended in a victory for the United Nations after large numbers of United States Army (US) and Republic of Korea Army (ROK) troops repelled a strong Korean People's Army (KPA) attack.
