The 6 Day Battle That Cost The Enemy An Entire Regiment JJ

November 14th, 1965. Late morning in the Central Highlands of South Vietnam. A clearing opens in the trees at the base of a mountain called the Chu Pong. The clearing is small, roughly the size of a football field, ringed by scrub brush, tall grass, and ant hills the size of a man. Eight helicopters come in low and fast, side by side, and flare into the grass.

Men jump out. They spread into the brush. The helicopters lift off again almost immediately, and the noise fades. And for a few moments, the clearing is quiet. The officer walking that grass is Lieutenant Colonel Harold G. Moore. He commands the 1st Battalion of the 7th Cavalry. He has about 450 men. Only a fraction of them are on the ground yet.

The rest are still back at a staging area waiting their turn, because there are only 16 helicopters available to move the whole battalion, and the clearing can only take eight at a time. That means his battalion will arrive in pieces over several hours. It also means that for the next several hours, Moore will have far fewer men on the ground than he needs.

He does not know that yet. He knows the general area is dangerous. He does not know what is above him. Rising directly off the western edge of the clearing is the Chu Pong Massif, a long mountain that runs across the Cambodian border. It is thick with trees and folds and gullies. From the air, it looks empty. It is not empty.

Somewhere on that slope, within easy walking distance of the grass where Moore’s men are now spreading out, are the better part of two North Vietnamese Army regiments, regular soldiers. Well-trained, well-armed, rested. They have been waiting in that area for weeks. They have been waiting, specifically, for a chance to fight Americans.

In about 40 minutes, one of Moore’s men is going to bring him a prisoner, and the prisoner is going to tell him what is on the mountain. And then this small clearing, chosen off a map that morning because it was one of the few places in the valley where helicopters could land, becomes the most important piece of ground in Southeast Asia.

What happens over the next 6 days will kill more Americans in a shorter time than anything yet in that war. It will also tear the heart out of an enemy regiment, and it will convince both armies that they had found a way to win. Both of them will be wrong. Before we go back into that clearing, let me say one thing.

If you like history told slowly and told properly, with the context left in, subscribing helps more of these get made. That’s all. Now, let’s get back to the grass at the foot of the Chu Pong. To understand why Hal Moore was standing in that clearing, you have to understand a problem the US Army had been chewing on for years.

The problem was simple to state and very hard to solve. Armies move on roads. Trucks need roads, supply convoys need roads, artillery gets towed down roads, reinforcements come up roads. If you took a standard American infantry division and set it down in country with no roads, most of it would simply sit there, and most of the ground in the middle of South Vietnam had no roads worth the name.

The Central Highlands is hill country, heavy woods, steep valleys choked with brush, farm villages scattered in the bottoms growing rice and sweet potatoes, cut off from the rest of the country for most of the year. Some of those farmers were still working their fields with hand tools and animals. There was no highway network to fight along.

In the rainy season, what tracks existed turned to soup. The enemy had adapted to that country long ago. He moved on foot in in groups along trails that no vehicle could use. He carried what he needed. He did not require roads, so roads could not be used to trap him. So, here was the American problem stated plainly.

We have more men, more guns, and more firepower, but we cannot get any of it to the place where the enemy is fast enough to matter. And by the time we do, he is gone. The answer the army came up with was to stop using the ground entirely. Not just for scouting, not just for hauling out the wounded, for everything. Move the infantry by helicopter.

Move the artillery by helicopter. Move the ammunition, the fuel, the food, the water, the radios, the replacement parts, the mail, all of it by helicopter. Build a division that did not need roads at all because it would never touch them. The idea had been studied and argued over for years. It had been tested at Fort Benning, Georgia by an experimental outfit called the 11th Air Assault Division.

Test exercises, umpires, written reports. On the 1st of July, 1965, the army stopped testing. On that date, the 1st Cavalry Division was formally designated the 1st Air Mobile Division in the United States Army. The experiment became a real division with real colors and a real mission. 10 weeks later, it was in Vietnam.

The lead elements came ashore on the 15th of September, 1965. And the very first thing the new division discovered was that its whole idea depended on something nobody had spent much time thinking about. It needed somewhere to put 400 helicopters. The place chosen was An Khe in the hill country inland from the coast. There was nothing there.

It was wilderness, brush, trees, and red clay. So, the division built it. They cleared the ground for an airfield large enough to park and launch hundreds of aircraft. They did not bulldoze the whole thing flat because bulldozing strips the topsoil and turns the place into a dust bowl in the dry season and a swamp in the wet. Instead, the brush and small trees were cut and hauled off and the grass root mat was left in place.

The result was a huge, flat, open field of low-cut grass and the men gave it a name that stuck. They called it the golf course. Within weeks, pilots all over Vietnam knew what you meant when you said the golf course. It could handle anything. Hundreds of helicopters could park on it. It could also take Air Force C-130 transports, four-engine cargo aircraft, coming in loaded from the coast.

Around the airfield, a town went up. Headquarters buildings, a communication center, an air operations shack, a control tower that on a busy day was handling about as much traffic as the tower at a mid-size American city airport, a large fuel dump holding the gasoline and oil that everything on that field burned by the thousands of gallons.

Runways and parking areas were surfaced with heavy aluminum matting laid down in interlocking panels because bare clay will not hold up under that kind of weight in that kind of rain. They poured concrete for a mess hall floor. They built a post office, a barber shop. They named the dirt streets after places back home, the way American units always have. None of that is glamorous.

All of it was necessary. A division that flies everywhere must have one place on Earth where it can land, refuel, rearm, and repair because it has no other way of staying alive. And that base was still growing on the day the division was ordered into the worst fight of its life. Here is the part of airmobile warfare that almost never gets shown, and it is the part that decides battles.

A helicopter is not a truck. A truck can be neglected, and it will still roll. A helicopter that is neglected falls out of the sky. Every hour a helicopter flies, it uses up its own parts. Engines wear, bearings wear, rotor systems go out of true. And in Vietnam, on top of all that normal wear, the aircraft were coming home with bullet holes in them.

So, the real measure of the division’s combat power was not how many helicopters it owned. It was how many were flyable at dawn. That number was produced every single night by men most people never heard of. The mechanics of the 229th and the other maintenance units working on the flight line, in tents, and in shipping containers that had been cut open and converted into shops.

They worked on engine stands set up outdoors in the open air, because there was no hangar. Two men would stand at a UH-1D and install a new hot end on the engine, the hot section, the part that takes the worst punishment, and then the aircraft would go back on the line. The most delicate work was the rotor system, bearing assemblies, pitch adjustments, measurements so fine that a piece of grit blown onto an exposed part could ruin the job.

That work had to be done under cover, inside the tent shops for exactly that reason. In a place where red dust hung in the air every time a helicopter took off, keeping dirt out of a rotor head was a daily fight. Nearby sat a parts depot, because a shop without parts is just a tent. The system had rules, and the rules tell you how seriously they took time.

If a repair was simple and could be finished in 4 hours, it was done in the field, wherever the aircraft happened to be. Get it fixed. Get it flying. If the job was bigger, the aircraft came back to An Khe, and the standard there was 72 hours, 3 days. And if it could not be fixed in 3 days, it did not sit around clogging up the shop.

It was shipped to the rear. Of course, in a division with no roads, shipped to the rear meant something unusual. It meant a wrecked aircraft was picked up and carried through the air by another aircraft. The division had a small number of Sikorsky CH-54 flying cranes, a strange-looking machine, mostly engines and rotor with a spine underneath and almost no body at all.

Built for one purpose, to lift heavy, awkward things and carry them somewhere else. A Caribou transport plane damaged at An Khe would be slung under a crane and flown out to the repair shops at Qui Nhon. The fuselage under one crane, the wings and tail sections carried in a pod under a second. Waiting ground crews would unload it as soon as it touched down.

A Navy Skyraider that crashed on approach at another field was hooked up, lifted, and flown out to a ship waiting in the harbor to be carried up the coast for repair. Slung on a cable, a load like that swings. The Skyraider’s own rudder acted like a weather vane in flight and helped steady it.

A shot-up Huey would come back to Qui Nhon under a crane and be set down gently on a bed of old tires to be looked over later and decided about. That is what a broken aircraft looked like in this division. Not a wreck by the side of a road, a wreck hanging under a cable 2,000 ft over the trees going home. All of it, the shops, the depot, the fuel dump, the cranes, the 72-hour rule, existed for one reason, so that when the infantry needed a ride into a fight, the ride would be there.

In the middle of November 1965, the infantry needed that ride very badly. None of this would have happened if the North Vietnamese had stayed quiet. They did not. In October 1965, a North Vietnamese force attacked a Special Forces camp at Plei Me in the Highlands near the Cambodian border. The camp was small and isolated, defended by a handful of Americans and local troops.

The attack was not really about the camp. It was a trap with a purpose. Hit an outpost hard enough and the relief column has to come. Then ambush the relief column on the road. That method had worked against the French and it had worked against the South Vietnamese. It was proven. The camp held.

Air support and a relief force got through and the attackers pulled back west into the brush toward the Cambodian border. And then the Americans did something the North Vietnamese had not planned for. Instead of declaring the siege lifted and going home, the First Cavalry Division was ordered to go after them. Not along the road, across country, by air.

For the next several weeks, Cavalry battalions hopped around the Highlands searching, landing, patrolling, lifting out, landing somewhere else. There were sharp little fights. There were ambushes. The enemy was with drawing and the division was chewing at his heels in a way no force had ever been able to do in that country before.

This was the airmobile idea working exactly as advertised. No roads needed. No convoys to ambush. Just clearings and helicopters and infantry arriving where they were not expected. But there was a problem the Americans had not yet solved. You can go anywhere by helicopter. That does not mean you know where to go. Finding an enemy who moves on foot under a solid roof of trees in country he has used for years is nearly impossible from the air. Air crews learned that fast.

Fly over a wooded ridge at treetop height and you may see nothing at all even while men are shooting at you from below. The jungle was not just cover. It was a screen the enemy could step behind and vanish. So, by the second week of November, American commanders knew roughly where the withdrawing North Vietnamese had gone into the valley of the Ia Drang River up against the Chu Pong Mountain close to the Cambodian border. They did not know how many.

They did not know that the enemy had not simply retreated there to hide. He had gone there to rest, absorb replacements, and prepare to attack again. And they did not know that in those hills sat a senior North Vietnamese commander who had spent the past weeks studying the American helicopters and drawing conclusions about how to beat them.

His conclusion was straightforward. American strength was firepower delivered from a distance, artillery, fighter bombers, helicopter gunships. The way to beat firepower from a distance was to remove the distance. Close with the Americans immediately. Get in among them. Grab them by the belt and hold on so that every shell and every bomb becomes as dangerous to them as to you.

On the morning of November 14th, he got the chance to try it. The mission given to Moore’s battalion was a search. Air assault into the Ia Drang Valley. Look for the enemy. Develop the situation. There were only a few clearings in the valley big enough for helicopters. Moore flew over them that morning and picked the one that could take the most aircraft at once.

On the map it was labeled X-ray. It sat within a few hundred yards of the foot of the Chu Pong. Artillery came first. Before any infantry touched the ground, two batteries of 105 mm howitzers had already been lifted in by Chinook to a clearing about 5 miles away, code named Falcon. That deserves a moment because it is the whole airmobile idea in one picture.

A 105 mm howitzer is a field gun. Normally, you tow it behind a truck, which means you need a road, which means the enemy knows where your guns can and cannot be. In the First Cavalry Division, a gun crew rolled the howitzer up the back ramp of a CH-47 Chinook, loaded the shells on pallets slung underneath, flew to a hilltop in the middle of nowhere, ran the gun off, and had it laid and ready to fire in minutes.

The Chinook lifted off as soon as it was empty before anyone on the ground nearby could work out what had just landed and start dropping mortar rounds on it. That is why Moore could land in a clearing 5 miles from nothing in country with no roads at all and still have artillery on call within a minute or two of asking.

At X-ray, that would turn out to be the difference between a bad day and a massacre. Just before 11:00 in the morning, the first lift touched down, about 80 men. The clearing was quiet. The riflemen fanned out. The helicopters went back for the next load, a 30-minute round trip. For the next half hour, Moore had one rifle company on the ground in a clearing at the foot of a mountain.

Then a patrol brought in a prisoner, a North Vietnamese soldier, thin, unarmed, who had been living on bananas in the brush. Under questioning, he said there were three battalions of regulars on the mountain above them and that they were eager to kill Americans. Three battalions against the one company Moore had on the ground. Moore did not have the option of pulling out.

Half his battalion was still in the air or waiting to be picked up. And an orderly withdrawal under fire from a single small clearing is not a thing you can do quickly. So, he made a decision that shaped everything that followed. He pushed his companies out from the clearing toward the mountain to find the enemy and fix him in place before the enemy could organize and come down on the landing zone in one mass.

Better to fight in the brush at a distance than to be overrun in the grass while unloading. Within minutes, the shooting started. And it did not stop for 2 days. The first crisis came fast, and it came from a mistake. One platoon, chasing enemy soldiers who were falling back up the slope, pushed too far.

The men were moving uphill through brush with the fight spreading around them. By the time anybody realized how far forward they had gone, North Vietnamese soldiers had already come in behind them. 29 men cut off on a slight rise, roughly 150 yd beyond the nearest friendly troops. Their platoon leader, Lieutenant Henry Herrick, was killed early.

So was the platoon sergeant who took over. So was the next man. Within a short time, the platoon was being run by a sergeant with a large share of its men dead or wounded, holding a piece of ground the size of a house lot. They could not break out. Any attempt to move meant crossing open ground under fire while carrying wounded men.

And the main body could not simply walk up and get them. Two separate relief attempts were pushed out from the perimeter that afternoon into heavy fire, and both were stopped with more casualties. Every failed attempt weakened the perimeter that Moore still had to hold. This is the hard arithmetic of a battle like that one. 29 men are cut off.

Trying to reach them may cost you 60 more. And if the perimeter breaks while you are trying, everybody dies. So, the cutoff platoon was told to hold, and artillery was walked in close around them through the night. So close that the shell bursts became their fence. They held. When they were finally reached the next day, more than half the platoon was dead or wounded, but the survivors were still there, still fighting, still holding their small rise.

That was one crisis. It was not the biggest one. The biggest one was that Moore’s battalion was burning through ammunition and water at a terrifying rate, had growing numbers of wounded men, and still had companies waiting to be flown in. Every single one of those problems had the same answer, and the answer was a helicopter.

Part eight. The pilots who kept coming. By early afternoon, landing zone X-ray was under direct fire. Machine guns and mortars were reaching the clearing. Helicopters coming in were taking hits on the way down, on the ground, and on the way out. At that point, the medical evacuation helicopters stopped coming in.

Their crews judged the landing zone too hot. That was a decision within their authority, and it is not hard to understand it, but it left Moore with an impossible situation. Wounded men were piling up in a shallow depression near the middle of the clearing. Without evacuation, many of them would die there. And without resupply, the perimeter would run dry and be overrun by morning.

The lift company was company A of the 229th Assault Helicopter Battalion, commanded by Major Bruce Crandall. His flight lead was Captain Ed Freeman. They decided to fly the missions themselves, not medical aircraft. Troop lift Hueys, with no red crosses and no special protection, flown by pilots whose job that day had been to deliver infantry and go home.

They went in again and again through the afternoon and into the evening down through fire into the same clearing every time because there was only one clearing. Crew chiefs and door gunners dragged ammunition crates and water cans out one side while wounded men were lifted in the other. Then up and out back to the pickup zone, load again and return.

The helicopters came back with holes in them. Some came back un-flyable. Crandall and Freeman changed aircraft and kept going. By dark they had flown the ammunition in that allowed the perimeter to survive the night and had carried out a large number of wounded men who would otherwise have died in the grass.

Both men were recognized much later. Ed Freeman received the Medal of Honor in 2001. Bruce Crandall received it in 2007, 36 and 42 years after the fact. And here is where all that un-glamorous work back at An Khe pays off. Every one of those shot up aircraft that made it home became a job for the mechanics.

Patch the skin, replace the components the bullets found, check the rotor system, get it flyable by morning because morning was when the infantry would need it again. The men in the tent shops at the golf course never saw X-Ray. Their contribution was measured in how many aircraft were on the line at dawn on the 15th of November.

That number mattered as much as anything a rifleman did. Also on the ground that first evening a civilian came in on one of the resupply flights. Joe Galloway, a young wire service reporter for United Press International, who had asked to be taken in and been taken in. He spent the battle inside the perimeter and years later he and Hal Moore would write the account that made this fight known to the American public.

Night at X-Ray was not quiet. There were probes against the line, flares overhead, artillery falling steadily on the approaches from the mountain. The North Vietnamese used the darkness to move battalions into position along the base of the Chu Pong. They came at first light. Not one attack, several, hitting different parts of the perimeter at nearly the same time, driving directly into the American line rather than trading fire at a distance.

That was deliberate. That was the plan that had been worked out in those hills over the preceding weeks. Get close, stay close, and take away the enemy’s ability to use his best weapons. It very nearly worked. One rifle company took the heaviest of it. Its position was pressed back, and at some points North Vietnamese soldiers got inside the line.

The fighting came down to individual men at a distance measured in feet, in tall grass, behind ant hills. It was in that fight that Second Lieutenant Walter Marm, faced with a machine gun position that was cutting his platoon apart and could not be reached with anything heavier, crossed open ground alone to destroy it.

He was badly wounded doing it. He survived, and he received the Medal of Honor. But individual courage was not going to decide this. What decided it was the thing Moore had set up before he landed. The guns at Falcon fired without pause, 5 mi away, dropping shells so close to the American line that the men could feel the shock through the ground.

Fighter bombers came in overhead. Helicopter gunships worked the approaches. Two errors happened, as they do. Napalm was dropped short inside the American perimeter, and men were burned. Some of them died. That is part of the record, and it should not be left out of it. By mid-morning, the attacks had been broken. The perimeter had held.

And then something happened over that mountain that had never happened before in that war. B-52 bombers, heavy strategic bombers designed for targets hundreds of miles behind a front line, were sent against the Chu Pong Massif. Aircraft flying so high they could not be seen or heard from the ground, dropping on the slopes where the enemies reserves and supply areas were.

For 6 days, those strikes came in on that mountain. The men in the clearing had asked for help. What arrived was an entire branch of the Air Force. Part 10, the march to Albany. By the 16th of November, X-Ray was secure. Reinforcing units had come in, including a battalion that walked overland from another landing zone.

The dead were collected, the wounded had been flown out. Moore’s battalion was pulled out by helicopter. Its fight was over. What most people remember about the Ia Drang ends there, with an American battalion standing on ground it had held against much larger numbers. But the battle had two more days left in it, and the second half is the part the army spent years studying.

On the morning of the 17th of November, two battalions were ordered to leave X-Ray on foot because the B-52 strikes were about to come in close to the clearing, and nobody could stay there. One of them, the 2nd Battalion of the 7th Cavalry commanded by Lieutenant Colonel Robert McDade, was ordered to march to another clearing a few miles north called Albany.

It was a routine movement order. That is the important thing to understand. It was not an attack. It was a walk to a pickup point. The men were exhausted. Many had been awake for 2 days. They had little water. They were moving through chest-high elephant grass and thick brush, where a man could not see the man 20 ft away, and they were doing the one thing the Airmobile Division had been created to avoid.

They were on the ground, on foot, strung out in a long column in country the enemy knew. By early afternoon, the column had stretched out over a considerable distance, a line of men hundreds of yards long in high grass with clumps of trees along the route. When the lead element reached Albany, the officers were called forward for orders. Along much of the column, men sat down in the grass to rest.

The ambush hit the column in the flank. The units that struck were from the North Vietnamese 66th Regiment and supporting elements, the same formation that had been fighting at X-Ray, still in the field, still capable. The attack cut the column into pieces almost immediately. In grass that tall, a company could not see the company in front of it.

Small groups of Americans found themselves fighting on their own, surrounded without knowing where anyone else was. And now the enormous American advantage in firepower turned into a liability. Artillery and air strikes require you to know where your own people are. At Albany, nobody knew. Friendly and enemy soldiers were mixed together across a mile of high grass.

Calling in fire risked killing as many Americans as North Vietnamese. Helicopters could not help, either. There was no clearing to land in along most of the column. The few that tried to get in came under heavy fire. The fight went on into the night. Men were killed at arms length. Wounded Americans lying in the grass were found and killed.

Others survived the night by staying absolutely still. When it was over, the 2nd Battalion of the 7th Cavalry had suffered roughly 155 men killed and 124 wounded in a single afternoon and night. It was the heaviest loss suffered by an American battalion in a single engagement in Vietnam up to that point. They had not been ambushed because the airmobile concept failed.

They had been ambushed because for a few hours they had stopped using it. Part 11, the cost, 6 days. From the first lift into X-Ray to the end of the fighting around Albany and its aftermath, American dead in the main fighting at X-Ray and Albany, approximately 234 with several hundred more wounded. North Vietnamese losses were far heavier, though the exact number will probably never be known.

American estimates ran from roughly 1,200 to over 1,800 killed. North Vietnamese figures are considerably lower. Both sides had reasons to count the way they counted. What is not really in dispute is what happened to the 66th Regiment. It had come down from the north as a complete, trained, well-equipped formation.

It went into the Ia Drang intending to fight a battle of its own choosing. It came out of the Ia Drang with its battalions shattered, so badly reduced that American commanders assessed it as no longer able to function as a regiment. It did not disappear forever. Units like that get rebuilt with replacements, and the 66th appeared again later in the war.

But the men who fought at X-Ray and Albany, the trained cadre, the experienced officers and sergeants who had marched down from the north, were largely gone. That is what it cost the enemy, an entire regiment’s worth of trained men spent in 6 days. On the American side, the human cost went home in a way the country was not ready for.

In some towns, the telegrams arrived by taxicab because there was not yet a system for delivering them any other way. Al Moore, who had promised his men he would be the first on the field and the last off, came home to help carry that news himself. Three weeks later, in the second week of December 1965, you could walk around the base at An Khe and see the machine that had fought the battle running as if nothing had happened. The rain had come.

The area had been soaked by heavy downpours, and the roads on the base were in poor shape, churned into mud by the constant traffic of trucks and jeeps moving between the shops and the airfield. On the flight line, the mechanics were doing what they had always done. Rotor work in the tent shops out of the dust. Engine hot ends going on out in the open.

Line crews handling the daily servicing. Aircraft that had been shot up being put right and returned to the line. The cranes were working. A damaged Caribou went out from An Khe to the repair shops at Qui Nhon, slung under one aircraft with its wings and tail carried in a pod under another. A crashed Skyraider was lifted out to a landing ship in the harbor.

A Huey fuselage came home and was set down on a bed of old tires to be looked over. At the airfield, the Christmas mail was coming in by the plane load. C-130s unloading sacks of it along with everything else. Vehicle parts, aircraft fuel, office supplies, spare components for the shops. The post office was busy.

The barber shop was busy. Somewhere on that base, men were being asked to think about re-enlisting, and in the division headquarters area, someone had set up a small museum. On display were weapons taken from the enemy in air assaults, recoilless rifles and other equipment, most of it communist made, laid out where men could walk past and look at it.

A quiet, matter-of-fact record of where the division had been and what it had done. Above all of it, on the top of Hong Kong mountain overlooking the An Khe pass, a radar site watched the surrounding country. The division looked, in December of 1965, like a permanent institution. Two months earlier, it had been a clearing in the brush, and it was still fighting.

During those same December days, helicopters of the 229th Aviation Battalion lifted an entire cavalry battalion into an area called Can Ik. Every aircraft in that lift took ground fire on the way in. Gunships were brought in to work the tree line. The crews could see the general area the shooting was coming from, around the edges of the clearings, so a pilot dropped down to treetop level for a closer look.

At that height, you can see a great deal. They saw nothing. The helicopters expended their rockets and their machine gun ammunition, went back to base, refueled, rearmed, and flew the mission again. That small moment, filmed 3 weeks after the Ia Drang, is the whole war in one picture. The division could put a battalion anywhere in the Central Highlands within hours.

It could put artillery on a hilltop that had never had a road. It could repair its own aircraft in the field and fly the wrecks home under a cable. What it could not do was make the enemy stand still. So, we come back to the question. The Air Mobile Division had been an experiment. In November of 1965, it was tested, hard, against regular North Vietnamese troops who had chosen the ground.

Did it work? Yes. Measured against what it was designed to do, it worked completely. A battalion was placed in a valley no truck could reach. Artillery was flown to a hilltop and firing within minutes. Ammunition and water reached a perimeter under fire. Hundreds of wounded men were lifted out of a clearing that no ground ambulance could ever have reached.

Reinforcements arrived by air in the middle of a battle, an enemy regiment was brought to battle and destroyed as a fighting unit, something no French or South Vietnamese force had managed to do in that country. By any military measure, the concept was proven. The airmobile division went on to become the model for how the US Army fought for the rest of the war, and helicopters remained at the center of American ground operations long after Vietnam ended.

But the six days in the Ia Drang taught two other lessons, and those lessons went in opposite directions. American commanders looked at the numbers. Roughly 234 Americans killed, somewhere between 1 and 2,000 North Vietnamese killed. A ratio of something like 1 to 6 or better. The conclusion drawn in Saigon was that if that exchange rate could be maintained, the North could be bled until it quit.

And that helicopters made it possible to force that kind of battle anywhere, anytime. That conclusion led directly to the strategy of the years that followed. Search out the enemy, bring him to battle, count the bodies, repeat. Hanoi looked at the same six days and drew a different conclusion. Their commanders had watched their men close with Americans and hold on so tightly that artillery and air power became useless.

They had watched an American battalion get caught on the ground, on foot, in high grass, and lose 155 men in an afternoon. They concluded that Americans could be fought, that helicopters were not magic, and that the way to survive American firepower was to grab the enemy by the belt and never let go.

They also concluded something simpler, that they could absorb losses on that scale and keep going, and that the Americans could not, not forever, and not in front of their own public. Both sides came out of the Ia Drang convinced the battle had shown them how to win. Both were half right, which in war is often worse than being wrong.

The machine at An Khe, the golf course, the tent shops, the fuel dump, the cranes, the 72-hour rule, the mail sacks, and the barber shop, and the little museum of captured rifles was a genuine achievement. American industry and American organization built something in a jungle clearing in 90 days that no other army on earth could have built.

It solved the problem it was built to solve. It made distance and terrain almost irrelevant. It could not answer the question underneath, which was never a question about transportation. For the men who came out of that valley, none of the larger arguments mattered much. What they remembered was a clearing the size of a football field, a mountain full of men who wanted to kill them, and the sound of another helicopter coming in low over the trees when they needed it most.

In six days at the Ia Drang, the United States Army proved it could go anywhere in Vietnam. The next eight years would be spent finding out that going anywhere was not the same thing as winning.
