By the end of November, the North Vietnamese were forced to withdraw from the area and back into their sanctuaries in Cambodia and Laos. Failing to wipe out a major American unit, yet the PAVN had forced the U.S. Army to pay a high price. 376 U.S. troops had been killed or listed as missing-presumed dead and another 1,441 were wounded, in the fighting around Dak To. The fighting had also taken a toll on South Vietnamese troops. 73 ARVN soldiers were killed in the fighting. U.S. munitions expenditures attested to the ferocity of the fighting: 151,000 artillery rounds, 2,096 tactical air sorties, 257 B-52 strikes, and 40 lost helicopters. The U.S. Army claimed that 1,644 PAVN troops had been killed by body count.
