Operation Texas was a US Marine Corps and Army of the Republic of Vietnam (ARVN) operation that took place northwest of Quảng Ngãi, lasting from 20–25 March 1966.


On the night of 18/19 March the Vietcong 1st Regiment overran the ARVN 936th Regional Force Company outpost at Hill 141 northwest of Quảng Ngãi, the ARVN 2nd Division commander General Lãm decided to send a reaction force to retake the outpost. The 120 man ARVN force collected from Quảng Ngãi by helicopters from HMM-261, but as they approached the outpost they were met with heavy machine gun fire damaging 8 of 10 helicopters and only 3 helicopters were able to land to offload their troops. Given the heavy fire encountered the decision was made to abort the operation and while Marine jets bombed the outpost, the helicopters returned to evacuate the ARVN troops. General Lãm then approached the 3rd Marine Division commander General Kyle to mount a joint operation to retake the outpost. On 19 March General Lãm and Colonel Oscar F. Peatross planned an operation similar to the recently concluded Operation Utah. The plan called for the 3rd Battalion 7th Marines and the ARVN 5th Airborne Battalion to be deployed by helicopters, 4 km west of Hill 141 and advance east in 2 columns to retake the Hill.[1]


20 March

On the morning of 20 March after preparatory air and artillery strikes, helicopters from Marine Aircraft Group 36 landed the Marine and ARVN units at the landing zone west of Hill 141 and began moving east. Company I 3/7 Marines was landed on Hill 141 where they found the bodies of 31 of the defenders.[1]:120–1

In the afternoon, Colonel Paul X. Kelley, commander of the 2nd Battalion 4th Marines, one of the operation's reserve units visited the 7th Marines command post and suggested that the Vietcong may have moved east from Hill 141 towards the coast and it was decided that this area should be searched.[1]:121

21 March

On the morning of 21 March 3/7 Marines moved southeast from Hill 141, 2/4 Marines was landed by helicopter southeast near the hamlet of Phuoc Dinh (2), while the ARVN 2nd Battalion 5th Regiment and an APC Company advanced southwest from Binh Son and the 3rd Battalion 5th Regiment advanced northwest from the direction of Quảng Ngãi.[1]:121

The helicopters carrying 2/4 Marines were met with heavy machine gun fire and Company F, the first to land had to repulse Vietcong attacks on the landing zone. Artillery fire was called in on Phuoc Dinh (2) and at 12:30 2/4 Marines began their attack on the village with Company D attacking from the north and Companies E and F attacking east.[1]:121 As the Marines began their assault on the village helicopter gunships from VMO-6 saw numerous Vietcong moving within defensive positions and the Marines were met by intense small arms fire. Company E penetrated the first layer of defenses but soon discovered 3 more lines of bunkers and barbed wire, while Company D was unable to penantrate the defenses. The 2/4 Marine command group was caught in a crossfire which killed or wounded 14 Marines and COL Kelley called for napalm strikes immediately in front of his positions. By 16:00 51 airstrikes and 1346 artillery rounds had been directed against the Vietcong positions and 2/4 Marines were able to disengage.[1]:123

Approximately 2 km north of Phuoc Dinh (2), 3/7 Marines encountered an estimated 2 Companies of Vietcong in bunker positions, after a 3-hour battle the Vietcong broke contact.[1]:124

At 16:00 the operational reserve 3rd Battalion 1st Marines and the ARVN 2nd Division Strike Company were deployed by helicopter to Xuan Hoa hamlet 1.5 km southeast of Phuoc Dinh (2). As they approached the landing zone a UH-34 from HMM-163 was hit by machine gun fire and crashed killing 7 Marines and 3 crew. As they approached Xuan Hoa the force encountered well entrenched Vietcong who engaged them until nightfall when they slipped away.[1]:124

North of Phuoc Dinh (2), the ARVN 5th Airborne and APC Company encountered a Vietcong Battalion near the hamlet of Khanh My (3), the Vietcong repulsed two ARVN attacks immobilising 9 M113s.[1]:125

22 March

Brigadier General Lowell English assumed command of the Marine forces, now renamed Task Force Delta. The Marines and ARVN resumed their attack at dawn but encountered little opposition as the Vietcong had slipped away during the night. The bodies of 168 Vietcong dead were found in Phuoc Dinh (2). BG English decided to extend the operation towards the south.[1]:125

23 March

In the afternoon 3/7 Marines was lifted by helicopter 9 km south to Phuoc Loc village. As the Marines advanced on the village they were met by well-entrenched Vietcong in a battle that lasted until nightfall. The Marines called in supporting fire and over 2000 artillery rounds were dropped on the village.[1]:126

24 March

The Marines had lost 7 dead and 56 wounded while Vietcong losses were estimated at 60 dead.[1]:126–7 Northeast of Phuoc Loc the ARVN engaged a Vietcong force killing 40.[1]:127

The Marines launched Operation Indiana deploying the 1st Battalion 7th Marines by helicopter to support the ARVN and encountered an estimated Vietcong Battalion near the hamlet of Vinh Loc (2). The Marines renewed their assault on Vinh Loc (2) the next day supported by 2nd Battalion 7th Marines but the Vietcong had abandoned the village during the night leaving 69 dead, while the ARVN claimed to have killed a further 100.
