The North Vietnamese launch a pre-dawn bombardment on 21 August against the combat base with many of its 200 heavy guns and 122mm rockets. One rocket scores a direct hit on the main ammunition dump located next to the airstrip, creating a massive explosion from 1,500 tons of bombs, shells and bullets. Secondary explosions occur for two days as the ordnance cooks off. The assault marks the beginning of the 77-day siege.
