In 1965, The NVA Lost LZ X-Ray. Their After-Action Report Won Them the War

You have marched three weeks for this. Down the Ho Chi Minh Trail through Laos, through the mountain passes, through jungle so thick your unit moves in single file for days without seeing sky. Your general has told you this is the moment the revolution tests itself against the Americans. Your regiment commander has given you a simple order, learn how to fight them.

 You have never seen an American soldier in combat. It is November 1965 and in a few days you will. This is the battle told entirely by the men who lost it. Every word of testimony is North Vietnamese. What they said afterward in their dispatches, their censure hearings, their military histories changed how the war was fought for the next decade.

The plan had a name, Major General Chu Huy Man, the B3 Front Theater Commander who controlled PAVN and Viet Cong forces across South Vietnam Central Highlands, called it luring the tiger out of the mountain. He had articulated it precisely in his own words to American authors Harold Moore and Joseph Galloway when they came to Hanoi in 1991 to meet the men they had once fought.

 We wanted to lure the tiger out of the mountain, Man told them. He meant the American military. The mountain was the coastal bases, the cities, the fortified perimeters where American firepower could be massed and concentrated. Man wanted to pull the Americans away from all of that into the Central Highlands where the jungle and the terrain would neutralize the advantages that air mobility gave them.

The strategy was built on an honest admission. Hoang found the PAVN battle historian who debriefed commanders after the battle stated it plainly when Moore’s team interviewed him. Our problem was that we had never fought Americans before and we had no experience fighting them. Hoang was not expressing weakness.

 He was describing a professional military organization that understood its own knowledge gaps. The French had been slow, methodical, and tied to roads. Whatever the Americans were, they were going to be something different and Man’s front wanted to find out what that difference was before the Americans had built enough force to be unstoppable.

We wanted to draw American units into the contact for purposes of learning how to fight them, Phuong said. We wanted any American combat troops, we didn’t care which ones. The vehicle for the test was a siege. In late October 1965, Man’s forces besieged the American Special Forces camp at Plei Me in the Central Highlands.

 The siege was not designed to capture the camp. It was designed to draw out an ARVN relief column, which it did, and then to force the Americans to commit ground forces to the region. Man’s explicit intention, we would attack the ARVN, but we would be ready to fight the Americans. The 66th Regiment had arrived at Chu Pong Mountain on 10th November, fresh, nearly full strength battalions carrying roughly 500 men each.

 The 33rd Regiment was there, too, already badly mauled from the Plei Me fighting. Together, they gave Man’s forward command approximately 2,000 soldiers in the Ia Drang Valley, positioned on and around the massive, watching the approaches. The plan was in place. The commanders were confident the tiger was about to arrive. They were not ready for it.

 The helicopters arrived before the commanders did. When the first UH-1 Hueys of Lieutenant Colonel Harold Moore’s 1st Battalion, 7th Cavalry touched down at a clearing they called LZ X-Ray on the morning of 14th November 1965, the 66th Regiment and 9th Battalion commanders were not at their posts.

 They were several kilometers away on the banks of the Ia Drang River, surveying terrain. The political officer of the 9th Battalion, the man in charge in the commander’s absence, panicked. He bolted from the command post, leaving the battalion leaderless. A first lieutenant took charge and threw cooks, runners, and medics into the fight.

 This is not American testimony. This is what PAVN historian Merle Pribbenow documented from a dozen Vietnamese language military histories, including the B-2 Front’s own after-action report of 1st January 1966. The PAVN’s own records stated flatly, “The 9th Battalion almost collapsed in the first minutes of contact.

” From the ground, Loc Cac Tam, a 9th Battalion platoon leader in the 66th Regiment, later described what he saw when the assault began. He gave testimony about it on camera for Ken Burns’ 2017 documentary The Vietnam War. “But then, swarms of helicopters came to our area. Everyone thought we might not survive, but I was a leader, and so I had to push that thought away.

” He was a second lieutenant commanding a rifle platoon. His battalion had not expected the landing where it came, had not detected the American approach, and had not had its command structure in place when the first shots were fired. Loc Cac Tam pushed the thought of dying away and led his men downhill toward the Americans landing below.

 Before that morning, his regiment had been in position for 4 days. They had been told what to expect. They had been told American infantry was coming. What they had not been told, because no one in the PAVN knew yet, was how fast American infantry moved with helicopters providing the lift. How much fire support would arrive simultaneously, and how effectively American artillery could be directed onto approach corridors while the assault was still underway.

 These were things the PAVN was about to learn. The 66th Regiment’s cost in that education was measured in the bodies it could not recover. Above the battle, on the Chu Pong Massif, Senior Lieutenant Colonel Nguyen Huu An ran the B3 Front’s forward command post and watched events unfold. An was the man giving orders at X-Ray, the on-scene field commander directing PAVN regiments while Man over saw the campaign from further back.

 Moore and Galloway would not learn this until they reached Hanoi in 1991. The fact of An’s specific role had not been in any public document they had access to. According to Pribbenow’s translations, An watched in dismay as US air strikes and artillery blasted the area where his 9th Battalion was fighting.

 His battalion’s political officer had fled. His commander was several kilometers away. A first lieutenant was running the battalion. An had directed the campaign from the Chu Pong Massif with the expectation that his units would mass, encircle, and hit the American infantry before they could bring their firepower to bear. What he was watching instead was a systematic destruction of a unit that had failed to form up before contact.

The first principle of the engagement had already failed. The Americans were in the LZ and they were not being overrun. The reports coming back were already wrong. Deputy Commander Pham Cong Cu of the 66th Regiment radioed that his men had overrun the American position and captured more than 70 weapons.

 The B3 Front, receiving this transmission, was skeptical. They asked if he had personally verified the claim. He had not. He had sent the report based on what men told him. His men were dying. The Americans had not been overrun. This was one night. Their own army would punish the men who had failed. And then, from the disaster, one idea would travel back to Hanoi that would keep the war going for another 10 years.

 Through the night of 14th of November and into the morning of 15th of November, PAVN battalions charged in waves toward the American perimeter at LZ X-Ray. They were meeting something their doctrine had not fully anticipated. 105-mm howitzers calling in fire within 100 m of the American lines, uh uh 1B Hog gunships firing rockets from above, A-1E Skyraiders dropping napalm on the mass approach corridors.

 Low [ __ ] Tam’s men had been ordered to fix bayonets before the assault as a symbol of fighting spirit. The PAVN soldiers fixed bayonets and charged into it. The 9th Battalion Commander had raced back from the IA Drang River. He reached his 11th company an hour after contact began. He never returned to his command post and never reestablished contact with all of his units.

 The 66th Regiment Commander, separately, became disoriented in the fighting and could not find his own headquarters. He was lost for 2 days. The PAVN kept attacking through the night anyway. The battalions came in waves charging across the open ground between the tree line and the American perimeter, taking casualties from the howitzers and the gunships and the napalm, pulling back and coming again.

The decision to keep charging was not irrational. PAVN doctrine held that the only answer to American firepower was closing the distance until the firepower couldn’t be used. They were trying to implement that answer in real time. At night, with command structures that had partially disintegrated, against opponents who had not broken.

 At first light on 16th November, an American mad minute, every weapon in the perimeter firing simultaneously, flushed a large group of PAVN soldiers who had crawled close to the wire overnight. The battle was ending. The PAVN withdrew. The self-assessment that followed was written by the B3 front itself and translated by Pribbenow.

 Successes were usually exaggerated and mistakes and failures were not reported. The army disciplined its own. All three regimental commanders involved in the Ia Drang campaign were officially censured. The 66th Regiment Commander received a severe reprimand specifically for failing to command his unit during the LZ X-Ray battle.

The PAVN did not excuse the failures as the result of American superiority. It held its commanders responsible for what had happened, documented the failures by name, and built the after-action review into the institutional record. In 1993, two decades later when Moore and Galloway returned to Vietnam, a Vietnamese colonel learned where an American machine gunner named Bill Beck had been positioned during the battle.

The colonel turned pale. He said, “You and your machine gun killed my battalion, 400 men. You killed my best friend.” He had been carrying that number for 28 years. The censures came after. An An Man sat down with what they had learned. The list of shocks was specific, according to Pribbenow’s translation of the PAVN’s own after-action analysis.

 They had been unprepared for armed helicopter firepower. They had not anticipated B-52 tactical bombing, which was being used for the first time in a close support role. They had been wrong about where American field artillery could deploy. They had assumed the terrain around the Ia Drang was impassable for artillery. The Americans had proven it wasn’t.

From these findings, a doctrine was constructed. It had a name, delivered decades later in An Zone voice, but built from the lessons in November 1965 itself. The armed helicopters were the most shocking element. Not because the PAVN had never seen helicopters, but because they had never seen helicopters carry rockets and mini guns as door weapons, hovering and firing as the infantry held the perimeter.

 The B-52 strikes, using close tactical support for the first time, had a different effect. They were terrifying and imprecise enough that units could disperse to avoid them. The artillery was the most lethal problem of all because it had no solution except one. “Move inside the column, grab them by the belt, and thus avoid casualties from the artillery and air.

” An told Harold Moore in Hanoi in 1991. “That was the idea that came out of X-Ray. Stay so close to American troops that their artillery couldn’t fire without killing their own men. Use American proximity to neutralize American firepower. Turn their most lethal advantage into a liability.” An identified it. Man confirmed it.

 “This is the first time we try our tactics, grab them by the belt buckle.” Man told Moore after the Ia Drang battles, “We are sure we will win the limited war.” Three days after X-Ray, An used the battered 8th Battalion of the 66th Regiment in a movement that collided with another American battalion, producing the ambush at LZ Albany on 17th November.

 It was a separate fight with heavier American casualties. The doctrine was already being applied. The 66th and 33rd Regiments were withdrawn, rebuilt, and folded into the newly formed 1st Infantry Division of the People’s Army of Vietnam on 20th December 1965, 35 days after LZ X-Ray. The army reconstituted what had been destroyed and built it into something new.

 Man’s verdict, delivered to Harold Moore in 1991, was the last word on what X-Ray had meant. After the Ia Drang battles, Man said, “We are sure we will win the limited war.” He was right. They lost the battle at X-Ray. The US Army counted 634 enemy dead on the field and estimated more than a thousand an killed beyond the perimeter. Three PAVN commanders were censured.

 Two regiments were rebuilt. And from the ruins of what went wrong on 14th of November 1965, they extracted one doctrine and applied it for the next 10 years. The tiger had come out of the mountain. The mountain had learned how to kill it. If your father served with the First Cavalry Division at LZ X-Ray or LZ Albany in November 1965, leave his name and unit below.

 The men who held that perimeter deserve to be remembered by name, even by the men who came for them.
