Korean War
In November 1950 the division entered Korea as a part of People's Volunteer Army. On November 28, 1950, the 80th Division hit the dispersed U.S. units of Task Force Faith with waves of infantry. Despite the presence of tracked antiaircraft weapons, the sub-zero cold and the constant Chinese attacks began to take their toll. The fighting was often hand to hand and convinced the U.S. Task Force commander, Colonel MacLean, to order a pullback to form a more consolidated defense. However, during the withdrawal operations his troops came under renewed enemy attack, and in the confusion MacLean was captured by the Chinese. Elements of the 80th Division also killed about 300 men from Task Force Faith. Almost all the men were wounded, who had been packed like sardines into trucks or trailers. Abandoned by the rear guard during the RCT's precipitous dash for safety with the Marines at Hagaru-ri, the wounded were trapped at a fire block. They were mostly killed by thermite grenades, thrown into the halted vehicles. The Task Force Faith page also states that the 81st Division participated in the attack, and that though they were possibly reinforced, comprised 15,000+ troops. The 80th Division suffered such severe casualties virtually wiping out Task Force Faith, that they did not reappear on the battlefield until March, 1951. During the campaign, the division, like all other units from the 9th Army Group, also suffered a lot from the cold weather. 40 percent of its combatants suffered from cold injury, and all but two personnel from 5th Company, 2nd Battalion, 242nd Infantry Regiment of the division were frozen to death on their perimeter before they attempted to ambush U.S. marines.
