Week of August 23

On August 25, 1966, Captain Peter S. Knight led Company A, 1st Battalion of the 16th Infantry Regiment, 1st Infantry Division, into a small jungle clearing in which hours earlier all hell had broken loose. Knight’s unit was part of a relief column sent to reinforce men that had been surrounded by Viet Cong troops during Operation AMARILLO, in III Corps. Shortly after reaching the besieged men, Knight spotted a fortified Viet Cong machine gun emplacement creating havoc a short distance away and led his men on a mission to take it out. Though exposed to fire and in the open, Knight rallied his men to the machine gunners and destroyed the emplacement. Knight was hit twice during the maneuver and was killed. He posthumously earned the Distinguished Service Cross for his actions.

Peter Knight was born in July 1935 in Key West, Florida, and he joined the United States Army in 1958, at the age of 23. By 1966, he had risen to the rank of Captain and was a company commander in the 1st Infantry Division, famously known from its World War I and World War II exploits as “The Big Red One.” In late August 1966, Military Assistance Command Vietnam assigned elements of the 1st Infantry Division to conduct Operation AMARILLO, a mission to clear the highways between the 1st Division’s headquarters at Di An and a brigade base at Phuoc Vinh. While an engineer battalion worked to improve the roads, which were in bad shape, the infantry units were assigned to eliminate the strong Viet Cong presence in the jungle surrounding the route.

Even by the middle of 1966, though the United States had, over 18 months, stemmed the tide of Communist victories in South Vietnam, Viet Cong forces remained in control of most of the countryside. While Saigon and other urban areas were relatively secure, the routes between these population centers remained largely enemy territory.

This was often due to South Vietnam’s rural topography, which made traditional military operations difficult. The road between Di An and Puoc Vinh, for example, was surrounded by thick forest situated on rolling hills and matted through by suffocating underbrush. Visibility was poor and tanks and armored vehicles could proceed only slowly, if at all, through this landscape. On top of that, AMARILLO took place at the height of the monsoon season, and heavy, near-constant rain pelted the ground into a boggy mess. In short, the area was ideal for guerrilla tactics, ambushes, and snipers. Although U.S. forces understood this, they were unaware that this particular stretch of road ran directly through a major Viet Cong base area, home to a well-trained unit of regular “mainline” fighters called the Phu Loi Battalion and a large complex of tunnels, trenches, and underground bunkers.

During the first phase of AMARILLO, early in the morning of August 25, the lead American elements were passing through a small clearing, barely large enough for a single helicopter to land, when the surrounding jungle seemed to unleash on them. Surrounded and apparently greatly outnumbered, the men in the clearing took immediate heavy casualties and scrambled to form a coherent defensive perimeter while enemy forces hit them with small arms, machine guns, and mortars—all fired from well-constructed, well-concealed positions. The Viet Cong machine gun nests, in particular, wrought havoc. Because they were fortified and camouflaged in the thick of the encircling jungle, they were difficult to see, let alone eliminate. A bit later, a medevac helicopter was shot down in the clearing, making relief only possible by ground assault.

The pinned-down men radioed for reinforcements, which luckily came in droves from multiple directions. Operation commanders dispatched relief columns from the South, East, and West, while two artillery batteries and fighter-bombers provided fire and air support for the besieged men. Captain Peter Knight and his company were part of the column coming from the West, the 1st Battalion, 16th Infantry Regiment, and they were the first to fight their way into the clearing. As Knight and his fellow soldiers entered the clearing, they began shuttling out wounded men on armored personnel carriers via the path through Viet Cong lines they had just blazed. At some point, Knight sighted a fortified machine gun bunker that was raking the platoon on his right. He called for a second platoon and led them rapidly across open ground to the trapped platoon, exposing himself and his men to automatic weapons fire. Knight was wounded by mortar shrapnel during this run, but he ignored it and turned to the matter at hand. Knight rallied both platoons for a flanking assault on the offending machine gun bunker. They reached the bunker and destroyed it, silencing the machine gun and its crew, but Knight had been hit a second time during the final assault. He died of his wounds on the battlefield.

Captain Peter S. Knight earned the Distinguished Service Cross, the United States’ second highest award for valor, for his bravery and sacrifice that day. He was also posthumously promoted to the rank of Major. He is memorialized on Panel 10E, Row 40 of the Vietnam Veterans Memorial Wall in Washington, D.C. Operation AMARILLO ended on August 31, though there was no further contact with the Viet Cong after August 26. A total of 41 U.S. servicemen were killed during the operation, with 34—including Knight—dying on August 25 alone.1
