Operation Birmingham was a military operation of the Vietnam War in War Zone C, north of Saigon conducted by the U.S. Army 1st Infantry Division against the Viet Cong (VC) 9th Infantry Division from 24 April to 17 May 1966.

Background

After the arrival of the American divisions in 1965 and early 1966, the communist also strengthened their force in B2 Front under the command of General Nguyễn Chí Thanh with the premier 9th Division in the north, the 5th Division in the east of Saigon, the 7th Division recent infiltrating from North Vietnam beside the elite 70th Guard Regiment and the U80 Artilery Regiment.

To counter the VC potential assaults in III Corps territory in the summer, the II Field Force commander, General Jonathan O. Seaman launched the 1st Division of General William E. DePuy on a preemptive campaign. A series of operations were carried out on Phước Tuy province, May Tao Secret Zone and Rung Sat Special Zone, southeast of Saigon, before DePuy turned his attention to Tây Ninh Province and War Zone C, northwest of Saigon to search and destroy the COSVN headquarters as well as the VC 9th Division's units.

Operation

Seven battalions of the 1st Division were moved to the area of operation (AO) in Phase I of the operation. Following 15 immediate and 45 pre-planned B-52 sorties struck the objective areas to secure landing zones, an infantry battalion and an artillery battery of the 3rd Brigade airlifted by helicopters into the AO on 24 April. Shortly afterward, the remainder of the 3rd, the whole 2nd Brigade, and two infantry battalions of the 1st Brigade arrived by fixed-wing C-130s. The following day, another four immediate and 42 pre-planned strikes were flown. On average, 315 tons of bombs were dropped per day during 24–26 April. Therefore, there were just a few light contacts in this phase.

Phase II of the operation began on 27 April with eight significant contacts initiated by U.S. forces in the day. A battalion of the 1st Brigade discovered and captured several tons of supplies, while a battalion of the 3rd Brigade found and destroyed a battalion-size VC base camp and several way stations. On the 27th, U.S. losses were one killed and 24 wounded, while VC losses were seven killed.

CHECO Report - Operation Birmingham 1966

On 30 April two battalions of the 1st Brigade swept north along the east bank of the Rach Cai Bac river on the border between South Vietnam and Cambodia attracting fire from both across the river in Cambodia and from the Vietnamese hamlet of Lo Go. The 1st Battalion, 2nd Infantry Regiment engaged the forces firing from Cambodia while the 2nd Battalion, 16th Infantry Regiment engaged the VC in Lo Go. The fighting at Lo Go continued into the afternoon when the VC, latter identified as coming from the C230 Battalion, withdrew leaving 54 dead. U.S. losses were six killed.

The operation continued for another two weeks as the 1st Infantry Division swept War Zone C in the hope of finding COSVN headquarters which was believed to located in northern Tây Ninh Province, but there were no other major engagements.

The operation also employed two brigades of the Vietnamese Mobile Guerrilla Forces (MGFs) whose primary objective was to locate and engage VC forces as well as to destroy their base camps along the Cambodian border. These brigades moved rapidly to exploit recently acquired intelligence on enemy installations and movements and were frequently transported by helicopter to locations throughout Tây Ninh Province. The MGFs utilized guerrilla warfare tactics that were often employed by the VC against U.S. and ARVN units.

Aftermath

The operation ended on 17 May 1966.
