La Vang
At the start of the attack, the ARVN 1st Regiment headquarters at La Vang and Col. Rattan's headquarters at Landing Zone Betty south of La Vang came under sporadic rocket and mortar attacks and ground assaults by elements of the 10th Sapper Battalion, while extremely heavy fog hampered visibility. The fog also prevented shifting the 1st Battalion, 8th US Cavalry Regiment's base camp in the mountains west of Quảng Trị. The 1st Battalion, 502nd Infantry Regiment, which was under the control of the 1st Cavalry Division, continued its base defense mission and patrols west of Quảng Trị.
