TAO
Quang Tri Province near Khe Sanh
Objective
combat operation; To relieve the Siege of Khe Sanh
Description
This operation required that the Army and Marines build LZ Stud just north of Ca Lu on Route 9. Because the Allies lacked information on the PAVN forces, the 1st Squadron, 9th Cavalry was sent to find PAVN strong points, destroy anitaircraft guns, and locate LZs. The Marines attacked north to confuse the PAVN on the 31 March. The operation officially began on the 1 April when the 1st Marines attacked westward. The 3d Brigade, 1st Cavalry Division conducted air assaults halfway to Khe Sanh, and converted the LZs to fire bases as they cleared Route 9 for the Marines. On 2 April, the 3d Brigade and the Marines kept up the air assaults to the west. An air assault the next day attacked from the southeast. On the 4th, the Marines in Khe Sanh took Hill 471 while the 2d Brigade attacked an old French fort to the south. In the following days, more air assaults around Khe Sanh met with PAVN resistance. Escape routes into Laos were blocked and the fighting became sporadic. On 11 April the 1st Marines opened Route 9. Though other attacks were planned for the area, the Allies were ordered to disengage. This Operation was the first full-division air cavalry raid in history. Khe Sanh was relieved very quickly and a reenactment of Dien Bien Phu never occurred.
