South Vietnamese fight for Fire Base Fuller - Jun 22, 1971 - HISTORY.com

In a major engagement near the Demilitarized Zone, some 1,500 North Vietnamese attack the 500-man South Vietnamese garrison at Fire Base Fuller. Despite U.S. B-52 raids dropping 60 tons of bombs on June 21 and a 1,000-man reinforcement on June 24, the South Vietnamese had to abandon the base since a North Vietnamese bombardment had destroyed 80 percent of their bunkers. In an attempt to clear the surrounding area of enemy mortar and rocket sites, South Vietnamese forces swept the region on June 25. On June 28, a Saigon spokesman announced that 120 South Vietnamese had reoccupied Fire Base Fuller, but would not rebuild the fortifications. Casualty figures were reported at nearly 500 North Vietnamese dead, with 135 wounded. On July 1, fighting again flared up around the base, as 300 communists were pushed back with the help of U.S. and South Vietnamese air power and with 150 additional South Vietnamese troops.
