Battle of Ia Drang (1965): First Major US Battle in Vietnam

The Battle of Ia Drang, fought from 14 to 18 November 1965 in the Central Highlands of South Vietnam, was the first large battle between the United States Army and the regular North Vietnamese Army. Helicopter-borne troops of the new 1st Cavalry Division (Airmobile) clashed with North Vietnamese regiments at two landing zones, X-Ray and Albany. The battle tested a new way of war and shaped the strategies both sides followed for years.

Background

In 1965 the United States moved from advising South Vietnam to fighting directly. After the Gulf of Tonkin Incident and the start of bombing in the North, President Johnson sent combat troops. The 1st Cavalry Division, commanded by Major General Harry Kinnard, arrived in September 1965 with more than 400 helicopters. It was the first division built around air mobility, carrying infantry, artillery and supplies by air.

North Vietnam was sending regular regiments south along the Ho Chi Minh Trail. In October 1965 they attacked the Special Forces camp at Plei Me, south of Pleiku, aiming to draw out and destroy relief forces. When the attack failed, the regiments pulled back west towards the Chu Pong massif near the Cambodian border, and the 1st Cavalry began searching for them.

LZ X-Ray: 14 to 16 November

On 14 November Lieutenant Colonel Harold G. Moore’s 1st Battalion, 7th Cavalry, was flown into a clearing at the foot of Chu Pong, named Landing Zone X-Ray. The helicopters could carry only part of the battalion at a time, so the force built up in waves through the day. Nearby were several battalions of the North Vietnamese 66th and 33rd Regiments, commanded in the field by Lieutenant Colonel Nguyen Huu An.

Fighting began within hours. A platoon of B Company chased enemy soldiers beyond the perimeter and was cut off; its leader, Lieutenant Henry Herrick, was killed, and Sergeant Ernie Savage held the survivors together through the night with artillery fire. Moore’s men, about 450 at first, fought off repeated assaults while helicopters flew through heavy fire to bring in ammunition and carry out the wounded.

At dawn on 15 November the North Vietnamese struck the southern edge of the perimeter. With positions in danger of being overrun, the Americans called “Broken Arrow”, a code that brought every available aircraft to support them. Artillery, fighter-bombers and, for the first time in direct support of ground troops, B-52 bombers struck the slopes of Chu Pong. Reinforcements from the 2nd Battalion, 7th Cavalry, and the 2nd Battalion, 5th Cavalry, arrived on foot and by air, and the cut-off platoon was rescued.

A final attack on 16 November was beaten off, and Moore’s battalion was flown out. About 79 Americans had been killed and 121 wounded at X-Ray.

LZ Albany: 17 to 18 November

On 17 November the 2nd Battalion, 7th Cavalry, under Lieutenant Colonel Robert McDade, marched towards another clearing, Landing Zone Albany, a few kilometres away. The column was strung out in tall elephant grass and forest when North Vietnamese troops, including a fresh battalion of the 66th Regiment, attacked it at close range.

The fighting broke into isolated, desperate struggles. Air and artillery support was difficult because the two sides were intermingled. By the time the survivors formed perimeters and help arrived, about 155 Americans had been killed and more than 120 wounded. Albany was one of the deadliest single-day actions for a US battalion in the war. Wounded men and the dead were recovered through 18 November.

Helicopters and firepower

Ia Drang was the first full test of the airmobile concept. Bell UH-1 “Huey” helicopters carried troops into battle, brought in water, ammunition and reinforcements, and flew out the wounded, often under fire when medical evacuation crews refused to land. Artillery batteries were lifted by helicopter to firebases within range of the landing zones and fired thousands of rounds.

Air power was decisive at X-Ray. Fighter-bombers dropped bombs and napalm close to the American lines, and B-52 bombers flying from Guam struck suspected North Vietnamese positions on the Chu Pong massif. Without this support, most historians agree, Moore’s battalion could have been overrun. At Albany, by contrast, the confused close-range fighting made it far harder to use these advantages.

The battle also showed the limits of airmobility. The helicopters could only bring in a company or two at a time, the landing zones were small, and a unit that moved on foot through thick cover, as at Albany, could still be surprised by a determined enemy.

Losses

US commanders reported 634 enemy bodies counted at X-Ray and estimated well over 1,000 North Vietnamese dead overall. These numbers are uncertain, and Vietnamese accounts give lower figures.

Key people

Harold G. Moore commanded at X-Ray and later wrote, with the reporter Joseph Galloway, the bestselling account We Were Soldiers Once… and Young (1992). Galloway, who carried a rifle during the fighting, later received the Bronze Star.

Helicopter pilots Bruce Crandall and Ed Freeman flew repeatedly into X-Ray under fire and were awarded the Medal of Honor decades later. Lieutenant Walter Marm also received the Medal of Honor for leading an assault on a machine-gun position.

On the North Vietnamese side, Nguyen Huu An directed the fighting at both landing zones and later became a senior general. Chu Huy Man commanded the wider front in the Central Highlands.

Lessons both sides drew

General William Westmoreland, the US commander in Vietnam, concluded that the battle proved American firepower and mobility could inflict losses faster than North Vietnam could replace them. This idea, measured by body counts, became the basis of the strategy of attrition.

Defense Secretary Robert McNamara visited Vietnam soon afterwards. In a memorandum to President Johnson at the end of November 1965, he warned that even a large increase in US troops might lead only to a military standoff at a much higher level of casualties.

North Vietnamese commanders drew their own conclusion: to fight so close to American troops that air and artillery support could not be used safely. This tactic, often summed up as grabbing the enemy by the belt, was used throughout the war.

Controversy over Albany

Early official accounts stressed the success at X-Ray and described Albany as a meeting engagement, playing down how badly the column had been hit. The scale of the losses only became widely known later, partly through Moore and Galloway’s book. Historians have since questioned the decision to march the 2nd Battalion through dense terrain after an exhausting battle, and the lack of security on the march.

Legacy

Ia Drang became one of the best-known American battles of the war through Moore and Galloway’s book and the 2002 film We Were Soldiers. It showed both the power and the limits of airmobile warfare, which would be used across Vietnam, including in battles such as Khe Sanh.

Why it matters

Ia Drang was the moment the Vietnam War became a conventional clash between the US and North Vietnamese armies. The lessons each side took from it, attrition for the Americans and close combat for the North Vietnamese, set the pattern of the fighting for years.
