My arrival…

The exception was a Task Force of the 1st Battalion, 61st Infantry, which included three day of heavy combat. In fighting, which occasionally became hand-to-hand, 60 North Vietnamese were killed, and the North Vietnamese Army command Post was overrun, and a large amount of equipment was captured.

In May 1970, D Company, 1st Battalion, 11th Infantry got the worst of an engagement when they were the perimeter security element for fire support base Fuller. They received 600 rounds of 120 mm mortar fire without being able to make effective reply. In January 1971, a reinforced 1st Brigade, now under the command of BG John C. Hill, Jr., initiated operation Lam son 719. The Brigade re-opened the QL9 Road from Dong Ha to the Laotian border; at the same time engineers constructed assess roads form the rock pile through the punch bowl to Khe Sanh. Following this, a 20,000-man ARVN Task Force moved to the Laotian border. The 2nd Brigade's missions were to secure QL9 as a supply route and provide mobile defense for the huge forward support area of Dangerdrift and Khe Sahn. For 69 days of increasingly confused and bitter fighting, the brigade prevented the enemy form making a successful offensive move against any of those vital links in the ARVN offensive. A body count of 400 North Vietnamese was made, and the primary mission to keep the logistical support channels fully operational at all times was accomplished by brigade. When the last of the logistical units had withdrawn, the 1st Brigade resumed its search and cordon patrols and rice denial efforts in eastern Quang Tri Province.

In June, the Red Devils received stand-down orders with stateside redeployment to commence on 1 July 1971. BG Harold H Dunwoody limited the Brigade activities to base security in anticipation of a North Vietnamese Army effort to achieve a propaganda victory over the departing unit. The brigade colors depart Quang Tri on 8 August 1971, after a ceremony the previous day in which several Vietnamese decorations were awarded to the Brigade and to Brigade personnel.

The Brigade returned to Fort Carson, leaving the defense of Quang Tri in the hands of the ARVN (Army, Republic of Vietnam) 1st Division, a unit which it had largely trained. On 22 August 1971, the Brigade colors were inactivated at Fort Carson until the next call-up of the Division.
