In November 1950 the division entered Korea as part of the People's Volunteer Army. At this time, the division consisted of the 172nd, 173rd, and 174th Regiments.

The 58th Division engaged U.N forces at Hagaru-ri and Kot’ori during the Battle of Chosin Reservoir. The division's attacks at Hagaru-ri were unsuccessful. The division's attacks at Kot'ori were unsuccessful in halting UN forces from reinforcing their positions Hagaru-ri, but it, along with the 60th division, inflicted severe losses on the convoy. Per official Chinese lore, Yang Gensi, commander of 3rd Company, 172nd Infantry Regiment, sacrificed himself when holding a strategic position with one of his platoons by throwing himself himself into a group of more than 40 UN soldiers while holding a satchel charge, killing himself and some UN soldiers. Yang was posthumously awarded the titles of "First Class Hero of People's Volunteer Army", and "Hero of Democratic People's Republic of Korea".
