addition, the US Air Force flew 272 missions and expended more than 500 tons of ordnance. US estimates of the losses incurred by the PAVN 7th and 8th Battalions of the 29th Regiment included 630 dead (bodies discovered on and around the battlefield); including many found in makeshift mortuaries within the tunnel complex. There is no count of the PAVN running off the mountain, those killed by artillery and air strikes, the wounded and dead carried into Laos, or the dead buried in collapsed bunkers and tunnels. During the ten-day battle, US forces captured 89 individual weapons and 22 crew‑served weapons.
