The Division's artillery and other elements assembled near the 38th parallel on 12 June 1950 and went into battle for the first time during the fighting around Chunchon on 26–27 June, where the artillery units were badly mauled by accurate counter-battery fire from artillery units of the Republic of Korea. During August and September, the Division fought in the Battle of Pusan Perimeter before heavy losses forced it to be re-organised in November at Kanggye. Losses were particularly bad for the Division's artillery units, so much so that by December when the Division participated in the II Corps flanking action in the Hwach'on Sector it did so without any artillery pieces.
