The Viet Cong Sent 2,000 Men to Overrun 200 Marines at Khe Sanh – It Was a HUGE Mistake

The hills around Khe San are quiet.

The fog sits low in the valleys like it always has, thick and cold in the hour before dawn.

The North Vietnamese Army officers standing in those hills can see the American combat base below them, a rectangular scar of red dirt and sandbags carved into the plateau.

Barbed wire, bunkers, a single airstrip.

They have 12,000 men in the mountains.

The Americans have maybe 6,000 total and most of them are dug in so close together you could walk the entire perimeter in 20 minutes.

The NVA commanders have artillery zeroed in.

They have supply lines running down from Laos.

They have orders from Hanoi.

This is going to be the next Dien Bien Phu, the battle that breaks the Americans, the siege that ends the war.

But what they don’t know is that every single Marine down in that base knows exactly what the NVA is planning.

And they’ve spent the last 3 weeks getting ready to make them regret it.

This is the story of the siege of Khe San and how 2,000 North Vietnamese soldiers learned the hard way that surrounding the Marines just means they can shoot in every direction.

Khe San Combat Base sat 6 miles from the Laos border in the northwestern corner of South Vietnam.

It wasn’t much.

An old French fort location, a plateau in the middle of elephant grass and triple canopy jungle, but it sat astride Route 9, the only east-west road in the region, and it overlooked the trails the NVA used to move men and supplies south.

In January, 1968, the base was held by the 26th Marine Regiment under Colonel David Lownds.

Three infantry battalions, artillery batteries, a composite squadron of helicopters and observation planes.

Around 6,000 Marines and ARVN Rangers total when you counted the outposts on the surrounding hills.

The hills mattered more than the base itself.

Hill 861, Hill 881 South, Hill 558.

Whoever held the high ground controlled the plateau.

The Marines had taken those hills the year before in some of the bloodiest fighting of the war.

Now they were dug in with bunkers, wire, and pre-registered artillery concentrations on every approach.

Intelligence reports coming into Saigon painted a clear picture.

The NVA was moving massive forces into the area.

Truck convoys on the Ho Chi Minh Trail, artillery pieces dragged through the jungle by hand, entire regiments crossing from Laos under cover of the monsoon clouds.

By mid-January, Marine reconnaissance teams were spotting NVA soldiers in battalion strength just outside the wire.

The strategic calculus was simple.

Khe San anchored the northern defense line.

If it fell, the NVA could pour forces into Quang Tri province and threaten the cities along the coast.

If it held, the NVA would bleed itself white trying to take it.

Either way, someone was going to pay a terrible price.

The NVA knew all of this.

They didn’t care.

General Vo Nguyen Giap, the man who beat the French at Dien Bien Phu 14 years earlier, was planning something bigger.

He had four divisions moving into position around Khe San.

The 304th, 325C, 324B, and elements of the 320th.

Between 20,000 and 40,000 men, depending on who was counting.

He had 152-mm artillery and 120-mm mortars in caves the Americans couldn’t reach, and he had time.

The comparison to Dien Bien Phu was deliberate.

In 1954, the Viet Minh had surrounded a French garrison in a valley and pounded it into submission with artillery the French never saw coming.

The siege lasted 57 days.

The French lost.

France pulled out of Indochina.

Giap wanted to do it again.

Khe San looked perfect.

A remote base surrounded by high ground.

Difficult to resupply.

Impossible to reinforce without massive casualties.

The plan was simple.

Surround the base, cut the road, pound them with artillery until they couldn’t be resupplied by air, then overrun them in human wave assaults the way they overran the French.

Giap told his officers this would be the decisive battle of the war, the one that proved the Americans couldn’t hold their ground, that their firepower didn’t matter, that they’d crack under pressure the same way the French did.

On the night of January 20th, 1968, the NVA made their move.

Hill 861A was held by Company 1, 3rd Battalion, 26th Marines.

Captain William Dabney commanded.

Around 180 Marines dug into bunkers on a ridgeline that looked north toward Laos.

They’d been reinforced with extra machine 81-mm mortars.

They had ammunition stacked in sandbag revetments and enough C-rations to last 2 weeks if they had to.

Dabney was 29 years old, Naval Academy graduate.

He’d been in country 8 months and knew the ground like his own backyard.

His Marines had walked every meter of that hill.

They knew where the dead ground was, where the NVA would have to cross open terrain, where to place the Claymore mines.

They were ready, but ready doesn’t mean it won’t be bad.

At 0530 hours on January 21st, the NVA hit them with everything.

Mortars first, then rockets, then a ground assault by an estimated 300 NVA soldiers from the 304th Division moving uphill in the dark.

The Marines opened up with M60 machine guns, M16 rifles, M79 grenade launchers, and the 81-mm mortars firing directly into the assault at near point-blank range.

The NVA kept coming.

They reached the wire.

They threw satchel charges.

A few made it into the trench line before killed them with rifles and entrenching tools and anything they could grab.

The fighting was hand-to-hand in places, muzzle flashes lighting up faces 6 ft apart.

The assault lasted 40 minutes.

When it broke, there were 47 NVA bodies in the wire and more scattered down the hillside.

Dabney’s company had seven wounded, no dead.

The Marines threw the bodies off the hill and restrung the wire before dawn.

That same morning, the NVA overran the village of Khe San, 2 miles from the base.

They shelled the combat base itself with mortars, rockets, and heavy artillery.

One round hit the main ammunition dump.

1,500 tons of ordnance cooked off in a fireball that could be seen from Da Nang.

The explosion shook the ground so hard it knocked men off their feet a quarter mile away.

Secondary explosions went on for hours.

Ammunition for the 105-mm howitzers, mortar rounds, grenades, CS gas canisters.

The smoke rose 10,000 ft and turned the sky black.

Half the base’s ammunition stockpile was gone in one hit.

Colonel Lownds radioed for air support.

He got it.

What the NVA didn’t know was that the United States had been waiting for them to try this.

The moment the siege began, the US military launched Operation Niagara, not a ground operation, an air operation.

The largest sustained application of aerial firepower in the history of warfare up to that point.

B-52 Stratofortresses flew Arc Light missions around the clock.

Each bomber carried 60,000 lb of high explosives.

They flew so high the NVA couldn’t hear them coming.

The bombs just appeared out of the sky in rolling waves of thunder that turned entire hillsides into moonscapes.

Radar guided them in through the clouds.

They never missed.

The strikes came in formations of three bombers at a time.

They flew from Guam and U-Tapao in Thailand.

Some missions lasted 12 hours round trip.

The crews never saw the target.

They never saw the results.

They just dropped on coordinates and turned for home.

Fighter bombers followed.

F-4 Phantoms, A-4 Skyhawks, Marine A-6 Intruders flying night missions with Snake Eye bombs and napalm, a C-47 Spooky gunship circling overhead with their mini guns putting a bullet in every square foot of a football field in 3 seconds.

The Marines on the ground called in fire missions by coordinates.

They had forward air controllers overhead 24 hours a day.

If the NVA moved, they got hit.

If they dug in, they got hit harder.

By 1800 hours on January 21st, Khe Sanh was surrounded.

The road was cut.

The base was under siege, and the NVA was already paying for it in blood.

Over the next 2 weeks, the NVA tried again and again to crack the Marine defenses.

They hit Hill 86, 1A3 more times.

They probed Hill 881 South.

They shelled the combat base with up to 1,300 rounds a day.

Rockets, mortars, artillery.

The Marines lived in bunkers reinforced with engineer stakes and sandbags stacked 6-ft thick.

They slept in flak jackets.

They moved between positions at a dead run.

The shelling followed patterns.

Heavy barrages at dawn and dusk.

Harassment fire throughout the day.

Anytime a helicopter tried to land, the mortars opened up.

Anytime engineers tried to repair the runway, the rockets came in.

The NVA forward observers were dug into the hills with clear line of sight to the entire base.

Resupply came by air.

C-130 Hercules transports flew into the airstrip under fire.

Touchdown just long enough to kick pallets out the back.

Then climbed out through the shelling.

When the airstrip got cratered too badly to land, they switched to low-altitude parachute extraction system drops.

The plane skimmed 6-ft off the deck at 130 knots and yanked the pallets out with parachutes while taking ground fire the whole way.

Some of those drops went into the wire.

Some landed in no man’s land.

Marines had to crawl out after dark to retrieve them while the NVA tried to booby trap the pallets first.

Helicopters brought in the wounded and the dead when they could.

But the fire was so heavy that medevac missions turned into combat assaults.

Door gunners fired suppression the whole way in and out.

Some days they couldn’t fly at all.

Some of those Marines never made it out.

Not because the NVA killed them, because the shelling never stopped and the medevac birds couldn’t land, and men bled out in bunkers waiting for an extraction that came too late.

But the Marines didn’t break.

They adjusted.

They adapted.

They dug deeper.

And every time the NVA massed for an assault, the forward observers called in the B-52s.

By 0200 hours on February 5th, sensors near Hill 861A detected movement, lots of it.

By 0400 hours, listening posts reported voices in Vietnamese just beyond the wire.

By 0430 hours, the NVA hit the hill with a reinforced company, maybe 200 men.

They came from three directions at once.

The Marines were awake.

They were always awake.

The M60 gunners opened up first, tracers arcing down the slope.

The 81-mm mortars followed, dropping rounds 50 m out.

Then the artillery from the combat base joined in, high explosive and white phosphorus turning the hillside into an inferno.

The assault lasted 6 hours.

The NVA kept coming in waves.

They’d pull back, regroup, and hit again from a different angle.

They used satchel charges to blow gaps in the wire.

They dragged their wounded back with them.

They left their dead.

The Marines held.

When dawn came, there were 109 NVA bodies in the wire.

Dabney’s men policed the battlefield and found AK-47s, RPG launchers, satchel charges, and documents showing the attackers were from the 304th Division’s 24th Regiment, elite troops, and they’d been slaughtered.

On February 7th, the NVA tried to overrun an outpost called Hill 64.

The Marines called in artillery so close it landed inside their own perimeter.

The assault failed, more bodies, more captured weapons.

By February 23rd, American aircraft had dropped 96,000 tons of ordnance on the hills around Khe San, more than was dropped on Japan in the final year of World War II.

The jungle stopped being jungle.

It became a landscape of craters and shattered trees and unexploded bombs half buried in the mud.

The NVA had never experienced anything like it.

At Dien Bien Phu, the Viet Minh had artillery superiority.

They pounded the French from the hills and the French couldn’t shoot back.

At Khe San, the Americans had total air superiority.

The NVA couldn’t move in daylight.

They couldn’t mass their forces.

They couldn’t build up supplies for a sustained assault because every time they tried, the bombs came.

One Marine listening post reported hearing NVA soldiers screaming in the jungle after a B-52 strike.

Not wounded screaming, insane screaming.

The concussion alone from those bombs could kill a man 300 ft away.

It collapsed lungs, ruptured eardrums, turned brains to jelly inside intact skulls.

The NVA kept trying.

They probed.

They shelled.

They died.

Captured documents later showed their supply lines were shattered.

Units were at half strength.

Morale was collapsing.

Men were deserting into Laos.

Officers were writing letters home saying they didn’t expect to survive.

But they didn’t pull back.

Giap wouldn’t let them.

This was supposed to be the decisive battle.

If they quit now, it meant the Americans had won.

So, the NVA stayed in the hills and died by the hundreds every day while the Marines sat in their bunkers and called in coordinates.

One Marine later said it wasn’t a battle, it was an execution.

The NVA were brave.

They were disciplined.

They kept attacking long past the point where any sane commander would have withdrawn.

And that’s exactly why they died.

The Marines weren’t clean heroes.

>> [music] >> They were exhausted, filthy, half crazy from the shelling.

Some stopped bathing because the showers were in the open and the NVA mortared them.

Some stopped sleeping more than 20 minutes at a time.

The stress showed in a thousand small ways.

Arguments over nothing.

Men staring at walls.

Others writing letters they knew might not get mailed.

But they held.

The siege officially ended on April 8th when the 1st Cavalry Division and ARVN forces broke through on Route 9 and linked up with the base.

The NVA faded into the jungle.

The hills went quiet.

The shelling stopped.

The butcher’s bill was lopsided.

The Marines lost 205 killed in action and another 1,668 wounded over 77 days.

The NVA lost an estimated 10,000 to 15,000 men.

Nobody knows the real number because they carried most of their dead away, but the bomb craters were still full of bodies when the engineers started clearing them.

Khe San was never overrun.

It was never even seriously threatened after the first 2 weeks.

The NVA had the numbers.

They had the positions.

They had the will to die.

What they didn’t have was an answer to American air power.

And once that became clear, the siege stopped being about taking the base.

It became about how long Giap was willing to feed men into the meat grinder before he admitted it wasn’t working.

The base was abandoned 3 months later.

The Marines tore it down and left.

The NVA moved back into the hills.

Both sides claimed victory, but only one side had 10,000 empty graves.

Captain Dabney went home.

So did most of his men.

Some didn’t.

Their names are on a wall in Washington now.

Sometimes the worst decision an enemy can make is giving you a fight you’re willing to die in.

The NVA wanted another Dien Bien Phu.

What they got was a 77-day lesson in what happens when you give the United States Marine Corps a hill to defend and all the time in the world to make you pay for wanting it.
