Description: Late in the night, the observation tower on Patrol Base Frontier City, manned by C/4/9th Inf, 25th Inf Div, detected movement southwest of the base. Three USAF Spooky and one Shadow minigum aircraft, 22 Cobra and Huey gunships and 4 jets arrived and started bombing, napalming and rocketing all suspected approach routes. The NVA responded with a barrage of rockets, mortars, grenades, and antiaircraft fire. One hour after midnight, a battalion of the 271st NVA Regt charged across the open ground and was decimated by the supporting fires. Waves of NVA were mowed down but 11 made it to the wire. The defenders set off the claymores and took them under fire with a 90mm recoilless rifle and two machine guns. The Americans suffered just one lightly wounded man while the NVA left 213 on the battlefield.
