Small units of the U.S. 2nd Battalion of the 119th Regiment attacked the Kampfgruppe Peiper during the morning of 21 December. They were pushed back and a number captured, including their battalion commander, Maj. Hal McCown. Attempting to withdraw from Cheneux, American paratroopers from the 82nd Airborne Division engaged the Germans in violent fighting. The Americans shelled Kampfgruppe Peiper on 22 December. Although the Germans had run out of food and had no fuel, they continued to fight. A Luftwaffe resupply mission went badly, parachuting supplies to American troops in Stoumont. In La Gleize, Peiper set up defences. He decided to break through back to the German lines on 23 December. The men of the "Kampfgruppe" abandoned their vehicles and heavy equipment.
