a key venue in various military coups, particularly the 1963 coup that deposed the nation's first President Ngô Đình Diệm. The plotters invited loyalist officers to a routine lunch meeting at JGS and captured them in the afternoon of 1 November 1963. The most notable was Colonel Lê Quang Tung, loyalist commander of the ARVN Special Forces, which was effectively a private Ngô family army, and his brother and deputy, Le Quang Trịeu. Later, Captain Nguyễn Văn Nhung, bodyguard of coup leader General Dương Văn Minh, shot the brothers on the edge of the base. On 14 April 1966 a Viet Cong (VC) mortar attack on the base destroyed 2 RVNAF aircraft and killed 7 USAF and 2 RVNAF personnel. The base was attacked by the VC in a sapper and mortar attack on the morning of 4 December 1966. The attack was repulsed for the loss of 3 US and 3 ARVN killed and 28 VC killed and 4 captured. 1968 Tet Offensive The base was the target of major VC attacks during the 1968 Tet Offensive. The attack began early on 31 January with greater severity than anyone had expected. When the VC attacked much of the RVNAF was on leave to be with their families during the lunar new year. An immediate recall was issued, and within 72 hours, 90 percent of the RVNAF was on duty. The main VC attack was made against the western perimeter of the base by three VC Battalions. The initial penetration was contained by the base's 377th Security Police Squadron, ad-hoc Army units of Task Force 35, ad-hoc RVNAF units and two ARVN Airborne battalions. The 3rd Squadron, 4th Cavalry Regiment was sent from Củ Chi Base Camp and prevented follow-on forces west of the base from reinforcing the VC inside the base and engaged them in a village and factory west of the base. By 16:30 on 31 January the base was secured. U.S. losses were 22 killed and 82 wounded, ARVN losses 29 killed and 15 wounded, VC losses were more than 669 killed and 26 captured. Fourteen aircraft were damaged at the base. Over the next three weeks, the RVNAF flew over 1,300 strike sorties, bombing and strafing PAVN/VC positions throughout South Vietnam. Transport aircraft from Tan Son Nhut's 33d Wing dropped almost 15,000 flares in 12 nights, compared with a normal monthly average of 10,000. Observation aircraft
