La Vang
The PAVN plan called for a platoon from the 10th Sapper Battalion to infiltrate the city on the evening of 30 January to pave the way for a major assault by elements of the 812th Regiment. The K4 Battalion and the 814th Main Force Battalion would supply the primary assaulting forces. At 02:00 on the 31st the sappers would emerge from hiding to destroy key installations in the city. At the same time the K4 Battalion would attack from the east and the 814th Battalion from the northeast. A 122-mm. rocket battalion (probably from the 54th Artillery Regiment) would provide supporting fire for the attack. The K8 Battalion would position itself along Highway 1 north of the city to block allied reinforcements coming from that direction. The K6 Battalion would block Highway 1 south of the city and attack the headquarters of the ARVN 1st Infantry Regiment, 1st Division, at La Vang Base. The 812th's K5 Battalion would remain in reserve in the village of Hải Lăng southeast of the city. Commandos from the 10th Sapper Battalion would also attack Landing Zone Jane south of La Vang to keep the American forces there tied down. The 814th and K4 Battalions would then occupy the city, and the remainder of the 812th Regiment would deploy in blocking positions in the surrounding area to prevent allied reinforcements.
