The 1st Cavalry Division deploys the 2nd Battalion, 7th Cavalry, at Ia
Drang two miles to the northeast of Landing Zone X-Ray. There they are ambushed
by Communist forces and nearly overrun until rescued by the 1st Battalion, 5th
Cavalry. American losses are 276 men to an estimated 400 Viet Cong.

The most significant individual battle of the Vietnam War
was fought on November 14, 1965 in the Ia Drang Valley in the Central
Highlands. It was the first engagement of North Vietnamese Forces and an
American unit, bolstered by the technology of the helicopter to deliver troops
into battle. The 1st Air Cavalry Division prevailed, but not without sustaining
significant casualties, and the victory was sealed when US airpower was
unleashed against the numerically superior forces of the PAVN. This earliest of
battles is described with great detail using eyewitness accounts in Hal Moore
and Joe Galloway ' s We Were Soldiers Once and Young (2004 [1992]). Such
writing was possible because the authors had been involved in the battle as
commander and reporter, respectively. They not only chronicle the battle moment
by moment, but they offer a gripping analysis of the impact of the outcome of
the battle on decision - making in Washington, Saigon and Hanoi. The American
leadership assumed massive force and technology would always prevail, and the
PAVN leadership decided to minimize force size to avoid casualties. They also
realized that Cambodia provided sanctuary: “I was always taught as an officer
that in a pursuit situation you continue to pursue until you either kill the
enemy or he surrenders... Not to follow them into Cambodia violated every
principle of warfare. It became perfectly clear to the North Vietnamese that
they then had sanctuary; they could come when they were ready to fight and
leave when they were ready to quit ". Ultimately, the North Vietnamese analysis
of the battle and subsequent battlefield strategy would prevail.
Operations in mid-October by units of the 1st Air Cavalry
provided intelligence on PAVN dispositions and General Westmoreland decided on
a spoiling attack. This resulted in the Battle of the Ia Drang Valley, a
forested area just east of the Chu Pong massif, from 23 October to 20 November.
It was the first major battle between PAVN and US Army units and one of the
war's bloodiest encounters.
On 27 October Westmoreland committed a brigade of the 1st
Air Cavalry to search-and-destroy operations. For two weeks there was sporadic
but light contact between the opposing sides. This changed on 14 November. Over
the next four days savage fighting erupted over landing zones (LZS) X-Ray and
Albany. It began when Lieut. Col. Harold Moore's understrength 1st Battalion of
the 7th Cavalry Regiment-some 450 men-landed at LZ "XRay" almost on
top of two PAVN regiments of 2,000 men. Outnumbered and in unfamiliar terrain,
the Americans fought desperately. In bitter, sometimes hand-to-hand combat, the
Americans drove back the attackers. Beginning the next day, 15 B-52 bombers
from Guam began six days of Arc Light strikes on the Chu Pong massif. It was
the first time that B-52s were employed in a tactical role in support of ground
troops. Moore's battalion was relieved by Lieut. Col. Robert Tully's 2nd
Battalion of the 7th Cavalry Regiment, which was then ordered to vacate LZ
"X-Ray" and march overland to "Albany" two miles away.
Three PAVN battalions ambushed the Americans en route, and in the most savage
one-day battle of the war 155 Americans were killed and another 124 wounded.
The battle ended when PAVN units withdrew across the border
into Cambodia. In a month of fighting the 1st Air Cavalry had lost 305 killed.
The Americans estimated PAVN losses at 3,561, less than half of these
confirmed. Both sides claimed victory. The PAVN learned they could survive
high-tech American weapons and the new helicopter tactics. They also learned to
minimize casualties by keeping combat troops close to US positions in what Giap
referred to as his "grab them by the belt" tactic.
The PAVN had inflicted heavy casualties on the Americans,
even while suffering horrendously themselves. But the PAVN leadership believed
that even lopsided body counts favoured them and would eventually wear down
American resolve. The Americans believed they had prevented a decisive PAVN success
before the US deployment could be completed. Westmoreland and his chief deputy,
General William DePuy, both of whom had learned their trade in the meat-grinder
battles of World War II, saw their estimated 12 to 1 kill ratio advantage as
proof that the war could be won through attrition, by carrying the conflict to
the PAVN in search and destroy operations. Indeed, Time magazine selected
General Westmoreland as its Man of the Year for 1965. In that year the United
States lost 1,275 killed, 5,466 wounded, 16 captured, and 137 missing. RVN
forces lost 11,403 killed, 23,296 wounded, and 7,589 missing. The Allies estimated
VC/PAVN dead at 35,382 killed and 5,873 captured.
The Battle
LTC Hal Moore, Commander of the 1st Battalion, 7th Cavalry, on the
radio during the fight for LZ X-Ray in the Ia Drang Valley of Vietnam. Hal
Moore regarded the battle as a draw, and I agree with that assessment. Another
veteran put it, "The survivors of Landing Zone X-Ray have always had an
aura of fame about them. They fought in the first violent "stand up"
fight of the war, and they won... barely."
The North Vietnamese Army attacked a Special Forces camp at
Plei Me; when it was repulsed, Westmoreland directed the division to launch an
offensive to locate and destroy enemy regiments that had been identified in the
vicinity of the camp. The result was the Battle of the Ia Drang, named for a
small river that flowed through the valley, the area of operations. For
thirty-five days the division pursued and fought the North Vietnamese 32d, 33d,
and 66th People's Army of Vietnam (PAVN) Regiments, until the enemy, suffering
heavy casualties, returned to his bases in Cambodia.
With scout platoons of its air cavalry squadron covering
front and flanks, each battalion of the division's 1st Brigade established
company bases from which patrols searched for enemy forces. For several days
neither ground patrols nor aeroscouts found any trace, but on November 4 the
scouts spotted a regimental aid station several miles west of Plei Me.
Quick-reacting aerorifle platoons converged on the site. Hovering above, the
airborne scouts detected an enemy battalion nearby and attacked from UH-1B Huey
gunships with aerial rockets and machine guns. Operating beyond the range of
their ground artillery, Army units engaged the enemy in an intense firefight,
killing ninety-nine, capturing the aid station, and seizing many documents.
The search for the main body of the enemy continued for the
next few days, with Army units concentrating their efforts in the vicinity of
the Chu Pong Massif, a mountain range and likely enemy base near the Cambodian
border. Communist forces were given little rest, as patrols harried and
ambushed them.
The heaviest fighting was yet to come. As the division began
the second stage of its campaign, enemy forces began to move out of the Chu
Pong base. Units of the U. S. 1st Cavalry Division's 3d Brigade, which took
over from the 1st Brigade, advanced to establish artillery bases and landing
zones at the base of the mountain. Landing Zone X-RAY was one of several U. S.
positions vulnerable to attack by the enemy forces that occupied the
surrounding high ground. Here on November 14 began fighting that pitted three
battalions against elements of two North Vietnamese regiments.
Withstanding
repeated mortar attacks and infantry assaults, the Americans used every means
of firepower available to them-the division's own gunships, massive artillery
bombardment, hundreds of strafing and bombing attacks by tactical aircraft,
earth-shaking bombs dropped by B-52 bombers from Guam, and, perhaps most
important, the individual soldier's M16 rifle-to turn back a determined enemy.
The Communists lost more than 600 dead, the Americans 79.
Although badly hurt, the enemy did not leave the Ia Drang
Valley. Elements of the 33d and 66th PAVN Regiments, moving east toward Plei
Me, encountered the U. S. 2d Battalion, 7th Cavalry, a few miles north of X-RAY
at Landing Zone ALBANY, on November 17. The fight that resulted was a bloody
reminder of the North Vietnamese mastery of the ambush, as the Communists
quickly snared four U. S. companies in their net. As the trapped units
struggled for survival, nearly all semblance of organized combat disappeared in
the confusion and mayhem. Neither reinforcements nor effective firepower could
be brought in. At times combat was reduced to valiant efforts by individuals
and small units to avert annihilation. When the fighting ended that night,
almost 70 percent of the Americans were casualties and almost one of every
three soldiers in the battalion had been killed.
Lessons!?
Despite the horrific casualties from the ambush near Landing
Zone ALBANY, the Battle of the Ia Drang was lauded as the first major American
triumph of the Vietnam War. The airmobile division, committed to combat less
than a month after it arrived in country, relentlessly pursued the enemy over
difficult terrain and defeated crack North Vietnamese Army units. In part, its
achievements underlined the flexibility that Army divisions had gained in the
early 1960s under the Reorganization Objective Army Division (ROAD) concept.
Replacing the flawed pentomic division with its five lightly armed battle
groups, the ROAD division, organized around three brigades, facilitated the
creation of brigade and battalion task forces tailored to respond and fight in
a variety of military situations. The newly organized division reflected the
Army's embrace of the concept of flexible response and proved eminently
suitable for operations in Vietnam. The helicopter was given great credit as
well. Nearly every aspect of the division's operations was enhanced by its
airmobile capacity. During the battle, artillery units were moved sixty-seven
times by helicopter. Intelligence, medical, and all manner of logistical
support benefited as well from the speed and flexibility helicopters provided.
Despite the fluidity of the tactical situation, airmobile command and control
procedures enabled the division to move and keep track of its units over a
large area and to accommodate the frequent and rapid changes in command
arrangements as units moved from one headquarters to another.
Yet for all the advantages the division accrued from
airmobility, its performance was not without blemish. Though the conduct of
division-size airmobile operations proved tactically sound, two major
engagements stemmed from the enemy's initiative in attacking vulnerable
American units. On several occasions massive air and artillery support provided
the margin of victory, if not survival. Above all, the division's logistical
self-sufficiency fell short of expectations. It could support only one brigade
in combat at a time, for prolonged and intense operations consumed more fuel
and ammunition than the division's helicopters and fixed-wing Caribou aircraft
could supply. Air Force tactical airlift became necessary for resupply.
Moreover, in addition to combat losses and damage, the division's helicopters
suffered from heavy use and from the heat, humidity, and dust of Vietnam,
taxing its maintenance capacity. Human attrition was also high: hundreds of
soldiers, the equivalent of almost a battalion, fell victim to a resistant
strain of malaria peculiar to Vietnam's highlands.
Westmoreland's satisfaction in blunting the enemy's
offensive was tempered by concern that enemy forces might reenter South Vietnam
and resume their offensive while the airmobile division recuperated at the end
of November and during most of December. He thus requested immediate
reinforcements from the Army's 25th Infantry Division, based in Hawaii and
scheduled to deploy to South Vietnam in the spring of 1966. By the end of 1965,
the division's 3d Brigade had been airlifted to the highlands and, within a
month of its arrival, had joined elements of the 1st Cavalry Division to launch
a series of operations to screen the border. Army units did not detect any
major enemy forces trying to cross from Cambodia into South Vietnam. Each
operation, however, killed hundreds of enemy soldiers and refined airmobile
techniques, as Army units learned to cope with the vast territorial expanse and
difficult terrain of the highlands.
