The 124th Division was a military formation of the People's Volunteer Army (Chinese People's Volunteers (CPV) or Chinese Communist Forces (CCF)) during the Korean War with a standard strength of approximately 10,000 men. It was a component of the 42nd Army, consisting of the 370th, 371st, and 372nd Regiments.
While the 124th Division at first drove back the ROK troops it encountered, and then slowed the advance of the U.S. Marine troops that replaced them on the road to the reservoir, it did not have the success that attended the CCF action against the ROK II Corps and part of the U.S. I Corps in the west. The 124th Division faced the 1st Marine Division at Sudong on November 2.
