1975
In 1975 Phung Duc Airfield was the base camp of the Army of the Republic of Vietnam (ARVN) 44th and 53rd Regiments. In the early morning of 10 March 1975 at the start of the Battle of Ban Me Thuot, the base was attacked by two People's Army of Vietnam (PAVN) sapper battalions. While the PAVN sappers quickly penetrated the 44th Regiment base area, which was defended by only rear echelon troops, they met stiff resistance in attacking the 53rd Regiment's base and by dawn had been pushed out of the base with the loss of over 100 dead. The PAVN 149th Regiment launched another attack against the 53rd Regiment's positions on 11 March, but were forced back with numerous casualties. From 12 to 13 March the ARVN 45th Regiment was dropped by helicopter onto Hill 581 1 mi east of Phung Duc to begin a counterattack to retake Buôn Ma Thuột which had fallen on 12 March. At dawn on 14 March, the 149th Regiment launched another attack on the base supported by six tanks, the attack was again beaten back with the loss of one tank. A further attack was scheduled to take place during the afternoon, but some of the supporting infantry failed to arrive on time. The attack took place at sunset and the tanks became disoriented in the fading light and vulnerable to ARVN fire, by midnight the attack was called off. Simultaneously with the attack on Phung Duc the PAVN 24th Regiment supported by tanks attacked the ARVN 45th Regiment on Hill 581 scattering the 45th Regiment, killing over 200 soldiers and ending the hopes for a counterattack to retake Buôn Ma Thuột. At 03:00 on 16 March the PAVN launched an artillery barrage on the 53rd Regiment base followed by a two pronged assault 90 minutes later by the 66th and 149th Regiments supported by tanks. The PAVN were unable to breach the base's earthen walls and lost two more tanks to rockets and anti-tank defenses. PAVN engineers eventually blasted a path through the defenses and by dawn on 17 March the PAVN had finally penetrated into the base. The 53rd Regiment commander Colonel Vo An and over 100 of his men managed to escape the base and make for ARVN positions at Phuoc An.
