By 1970, the Vietnam War had entered a strange new phase. American troop withdrawals were accelerating, Vietnamization was the watchword in Washington, and the 101st Airborne Division was still fighting hard in the mountains west of Huế. Operation Texas Star, launched on April 1 of that year, captured the contradictions of that moment: a massive combined operation with two ambitious goals — build up rural communities and simultaneously hunt North Vietnamese Army forces in some of the most difficult terrain in Southeast Asia. For five months, across the jungle highlands and river valleys of Quảng Trị and Thừa Thiên Provinces, American and South Vietnamese soldiers lived and died in those contradictions.
Operation Texas Star followed Operation Randolph Glen, and it inherited that mission's split personality. One brigade of the 101st Airborne Division stayed close to the villages, working pacification and rural reconstruction programs — the unglamorous, painstaking work of winning over a population exhausted by decades of conflict. The other two brigades pushed west into the jungle highlands, conducting offensive operations against the People's Army of Vietnam (PAVN) in the rugged terrain that funneled North Vietnamese supply and maneuver routes toward the coast. The Army of the Republic of Vietnam's (ARVN) 1st Division fought alongside the Americans throughout, its battalions taking the fight to the PAVN with increasing effectiveness as Vietnamization took hold. Together, they represented something the early years of the war rarely achieved: a genuine combined force operating with a shared mission.
The operation's daily rhythms were measured in kilometers and contacts. On May 1, ARVN soldiers of the 3rd Battalion, 3rd Regiment were working a search operation 46 kilometers northwest of Huế when they found elements of the PAVN 812th Regiment. Artillery and aerial rocket artillery did the rest; fifteen North Vietnamese soldiers were killed, none of the South Vietnamese. Twelve days later, in the early hours before dawn, the 3rd Regiment struck a PAVN platoon west of Huế and killed 21. The engagements continued through the spring and summer — night defensive positions hit with coordinated attacks, command posts raked by mortar rounds, reconnaissance platoons ambushing enemy columns. On May 27 alone, Firebase O'Reilly, 40 kilometers west of Huế, withstood a two-hour assault by the reinforced PAVN 5th Battalion, 812th Regiment. When the North Vietnamese withdrew, they left 74 of their soldiers behind. The ARVN lost three.
Through July, the operation's center of gravity shifted to Firebase Ripcord, a hilltop fire support base in the A Shau Valley region that had become a flashpoint. The North Vietnamese methodically tightened a noose around the base, pounding it with mortars and rockets, probing its defenses, cutting off resupply helicopters. The battle that followed was one of the bloodiest and least-remembered of the American war in Vietnam. On July 23, 1970, U.S. commanders ordered Ripcord's evacuation — a decision that acknowledged the base could no longer be held at an acceptable cost. The Americans destroyed what they could not carry and left. It was a tactical retreat that did not make the front pages at home, where attention had already shifted toward the peace negotiations in Paris.
When Military Assistance Command, Vietnam officially concluded Operation Texas Star on September 5, 1970, the official tally listed 1,782 PAVN soldiers killed. American losses stood at 386 killed over five months of operations. These figures, as with so many from this war, carried the particular uncertainty of contested ground: body counts were notoriously unreliable, and the PAVN's actual losses may have differed significantly from the American claims. What was beyond dispute was the cost paid by the American soldiers and the South Vietnamese troops who fought alongside them. The provinces they fought for — Quảng Trị and Thừa Thiên — would see further heavy fighting in 1972, when a massive North Vietnamese offensive rolled south across the DMZ. The hills and firebase sites where Texas Star's soldiers had bled would change hands again, as they had before and would again.
The ground over which Operation Texas Star was fought lies in the present-day provinces of Quảng Trị and Thừa Thiên-Huế, in the narrow strip of central Vietnam between the mountains and the sea. The ancient citadel of Huế, heavily damaged during the 1968 Tet Offensive, has been largely restored and draws visitors from around the world. The highlands to the west remain sparsely populated, the old firebase sites absorbed back into jungle or converted to agricultural land. Route 9, which runs east-west through the region, passes near many of the battle sites and connects to the former DMZ and Khe Sanh. For those who travel it today, the distances between place names on the map — Huế, the A Shau Valley, Firebase O'Reilly — compress into an hour's drive what once took days of helicopter movement and weeks of jungle fighting.
Centered at approximately 16.58°N, 106.79°E, in the highlands of central Vietnam west of Huế. The operation covered a broad swath of Quảng Trị and Thừa Thiên Provinces; the former Firebase Ripcord area lies roughly 35 km west of Huế at about 16.3°N, 107.1°E. Approach from the coast to appreciate the dramatic transition from the coastal plain to the heavily forested mountain terrain. Recommended viewing altitude: 3,000–5,000 feet for the broad valley and ridgeline context. Nearest airports: Phu Bai International Airport (VVPB), approximately 15 km southeast of Huế; Da Nang International Airport (VVDN), 80 km to the south.
