In 1942, Japan Attacked A Thin American Line. Nobody Warned Them About The Water-Cooled Guns.

In 1942, Japan Attacked A Thin American Line. Nobody Warned Them About The Water-Cooled Guns.

The Marines who defended Henderson Field rarely used the name printed on their maps. To them it was just a strip of coral and packed clay on the northern shore of Guadalcanal, carved out of the jungle by hand and bulldozer. But in October 1942, that strip was the only reason they were still alive. Whoever controlled it controlled the skies over the southern Solomon Islands, and both sides understood this completely.

On the night of October 24, the Japanese came to take it back. A full division moved through rain-soaked jungle straight toward the weakest part of the American perimeter. What they did not know was that a Marine sergeant named John Basilone had already sighted two water-cooled machine guns precisely across their line of advance.

An ordinary air-cooled machine gun would have burned out and quit within the hour. These did not. By the time the sun rose over the airstrip, the grass in front of those guns was stacked with Japanese dead, and Henderson Field was still American.

What actually happened that night is not quite the story that has been passed down through the generations.

For two months before that night, the First Marine Division had held a shallow defensive ring around Henderson Field, and for two months the Imperial Japanese Army had tried to break it. The Marines had landed in August and seized the nearly completed airstrip before the Japanese even realized anyone had come ashore. Holding it turned out to be the harder job.

The island sat at the frayed end of a long American supply line and at the near end of a short Japanese one. Japanese warships cruised the strait between the islands most nights to shell the airstrip in the dark. Bombers came by day. And behind the wire, in the jungle, the enemy kept massing for something bigger than a raid.

They had come close before. Back in September, on a low ridge just south of the airfield, a few hundred Marines had stopped a night attack that got close enough to reach the edge of the division command post. The Marines called that ridge Bloody Ridge afterward. It was a warning nobody ignored. The southern approaches were the weak point, and the Japanese knew it as well as anyone.

The man tasked with retaking the airfield was Lieutenant General Harukichi Hyakutake, commander of the Seventeenth Army. On paper, his plan made real sense. A force near the coast would make noise along the Matanikau River in the west, drawing American attention and reserves in that direction. Then the main force, the real weight, would come from the south through jungle terrain the Americans had written off as impassable.

That force was the Second Division, known as the Sendai Division, regarded as one of the finest infantry divisions in Japan. By the time it reached the staging phase, the plan was already falling apart.

To reach the southern edge of the American perimeter, Lieutenant General Masao Maruyama marched his division along a trail his engineers cut inland, a route later known as the Maruyama Road. The trail crossed rivers, cut through ravines, and climbed hills under cover so dense that rain never had a chance to dry. Each man carried his rifle, his pack, and an artillery shell on his back, because the guns themselves had to be broken down and carried by hand. Most of the heavy weapons never arrived at all.

A march that was supposed to take a few days turned into a week of exhaustion and starvation. By the time the Sendai Division finally reached the jungle south of the airfield, the men were starving, soaked through, and far behind schedule. They kept coming anyway.

The diversionary attack from the west began first. On the evening of October 23, Japanese artillery opened up on the Marine lines along the Matanikau River and tanks rolled forward behind it. Nine or ten light tanks headed for the river mouth with infantry massing behind them.

The Marines were ready. 37mm anti-tank guns fired canister at point-blank range. 75mm shells from a half-track punched straight through the lead tanks. One tank climbed a tree stump, threw its track, and was pushed back toward the surf. Behind the wrecked armor, two Japanese infantry battalions tried to push through a gap that never opened.

Marine howitzers, positioned around the field, rained more than 6,000 shells on them through the night. By the small hours, it was over. Marine patrols later counted roughly 600 dead in that sector alone.

The diversion failed as an attack, but it succeeded at something else. It convinced the Americans that the western attack was the real one, pulling reserves in that direction. That left the entire southern face of the defensive perimeter in the hands of a single reinforced battalion, about 700 men, strung along 2,500 yards of hills and jungle.

It was a front that called for twice that many men, and it sat directly in the path of Maruyama's starving, exhausted division, which was still dangerous. That battalion was the First Battalion, Seventh Marine Regiment. Its commander was a short, barrel-chested officer everyone called "Chesty," Lewis Puller. He was about to spend the longest night of his life.

The weapon waiting for the Sendai Division in that sector looked almost obsolete. It was the Browning water-cooled machine gun, the Model 1917, later updated to the 1917A1, designed by John Browning a generation earlier. Compared with the sleeker automatic weapons of the 1940s, it looked heavy and primitive.

A thick barrel on a short tripod, fed by a 250-round cloth belt, firing the same .30 caliber round the infantry carried at 500 rounds per minute. None of that made it special. What made it special was what wrapped around its barrel: a steel jacket holding seven pints of water.

Every machine gun ever built shares the same real enemy, and it is not the enemy in the field. It is heat. Fire a barrel long enough and it will glow, then warp, then fail, and the weapon keeping you alive becomes a useless piece of steel.

Air-cooled guns handled this by firing in short bursts and pausing to cool. The American air-cooled Browning, the Model 1919, could not even swap barrels quickly under fire, so its crews learned to ration it because they had no other choice. The water-cooled gun needed to ration nothing.

As long as the crew had ammunition and water, the barrel stayed serviceable, belt after belt, deep into the night, long after an air-cooled weapon would have been destroyed. When Browning first demonstrated the design to the Army, one test gun ran continuously for 48 minutes and 12 seconds, firing more than 21,000 rounds from a single barrel without stopping. That endurance was the entire point of the weapon.

In a defensive battle against infantry creeping forward in waves through the dark, the ability to keep firing without pause was the difference between a line that held and a line that collapsed.

The man who placed two of these guns directly in the path of the Sendai Division had grown up far from any jungle. John Basilone was from Raritan, New Jersey, one of 10 children in an Italian American family. Before he became a Marine, he was a soldier in the Army, a enlistment that took him to the Philippines, where he boxed well enough to earn a nickname that stuck for life: "Manila John."

He left the Army, drove a truck for a while, found he could not sit still, and joined the Marines. By the fall of 1942 he was a sergeant on Guadalcanal, running two heavy machine gun sections in the weapons company of the First Battalion, Seventh Marine Regiment.

He knew these guns the way a gifted mechanic knows an engine. He could strip the weapon blindfolded, fix a jam by feel, and direct fire onto a target by sound and tracer alone. In the days before the attack, he and his men sited their guns along the southern wire with great care, overlapping their fields of fire so that anything crossing the open ground in front of them would face a crossfire of .30 caliber rounds from more than one direction at once.

At dusk, they fired a few short test bursts toward the tree line to confirm their ranges, then let the barrels cool and settled in to wait under the rain.

One of the men who fought beside Basilone that night spent the rest of his life telling people the battle lasted three days and three nights without stopping. The official record tells a different story, measured in hours rather than days. Both accounts are true in their own way, and the gap between them is the most honest part of the whole legend.

Hold that thought. It says more about what actually happened that night than anything else. For now, understand only this: the Sendai Division was about to throw itself at the strongest point in a thin defensive line, at night, on foot, against guns that had no reason to ever stop firing.

Rain fell on the southern perimeter all evening on October 24, the kind of tropical downpour that fills trenches faster than a man can bail them and hides anything moving in the jungle a few hundred yards away.

At an outpost forward of the line, a sergeant named Ralph Briggs managed to work a field phone long enough to reach Puller's command post. He reported roughly 3,000 Japanese soldiers between his position and the main line. They were close enough to hear talking and smell cigarettes, and they were moving toward the wire.

Then the line went dead, and Briggs and his small group of men had to slip back through the enemy ranks in the dark to reach their own side. Puller gave his order: fix bayonets. Do not fire until the last possible moment.

Shortly after 1 a.m. on October 25, the Sendai Division came out of the rain. They came the way Japanese infantry had attacked Marines before, in a fast rush, some of them shouting, firing from the hip, throwing grenades, a mass of men trying to cross open ground faster than the defenders could kill them.

The leading group, the 9th Company of the 29th Infantry Regiment, charged straight into the sector covered by Basilone's guns. The guns opened up. At 500 rounds per minute from more than one position at once, the machine gun fire caught the attackers in the open and tore them apart.

The overlapping cones of .30 caliber fire cut down the grass, and the men trapped in it found nowhere to go and nothing to hide behind. Within minutes, the 9th Company had essentially ceased to exist as a fighting force.

The water in the cooling jackets began to heat up. Behind the 9th Company came more companies, and behind them more still, the exact scenario the water-cooled weapon was built for. An air-cooled gun firing at that rate for that long would have failed, its barrel glowing, its crew forced to pause to cool it or watch the weapon destroy itself.

The Brownings never stopped. Belt after belt fed into the guns, the water climbing from warm to hot to boiling, steam rising off the barrels in the rain, and the fire never slackened. The men feeding the guns worked like an assembly line, mounting a fresh belt before the last one ran out, calling for more, while the ground in front of them filled with the dead and wounded and men crawling among them.

For the soldiers of the Sendai Division, that patch of open grass became ground they could not cross. They had marched a full week to get here. Now they walked into a wall of fire that seemed to come from every direction and never paused to catch its breath. And so row after row went down in that hell.

Japanese accounts written later keep returning to that fire, to the sense that the American line was solid as steel and could not be weakened by any number of men. It was not only the machine guns. Along the southern front, Marines fired their rifles until their weapons failed. Mortar crews dropped shells behind the barbed wire, and the artillery around the field combed the approaches with precise rounds called in by men who could hear the enemy moving in the grass.

The night became one continuous roar lit by muzzle flashes and the white glare of parachute flares drifting through the rain. Some attackers made it through the fire and reached the wire, and the fighting there turned into close, vicious work. Grenades were thrown back and forth across a few yards of mud. Men fired at shapes and shadows they could barely make out.

Basilone kept his guns running through all of it, and when the enemy got closer than a machine gun could handle, he switched to his heavy .45 pistol, emptied it, reloaded, and emptied it again. At one point, a group of Japanese soldiers reached his position in the dark, and he fought them hand to hand before getting back behind his gun.

None of it was clean or orderly, nothing like the neat firing lines of training films. It was a bloody fight in rain and mud, decided yard by yard, and it went on for hours.

Then the enemy found the range. A Japanese mortar shell or a grenade from a crew working in close landed directly on one of Basilone's guns. The explosion killed or wounded the crew and silenced both guns.

A gap opened where no gap could be allowed, because the attack was still coming, and a silent gun in a line like that is an open door. Basilone was at his other position when it happened. What he did in the next few minutes is why his name is still spoken today.

He grabbed a spare gun, roughly 90 pounds of steel, water, and tripod that was supposed to be carried by two men, and ran with it along the line toward the wrecked position, through the dark and under enemy fire, set it up by himself, and put it back into the fight.

Then he went to the two guns that had gone silent. One was completely out of action. He stripped it down there in the mud, working by feel in total darkness, cleared the jam, reassembled it, and got it running again himself, holding that part of the line with two working guns after there had been nothing moments before.

For the men around him, the whole war shrank to a few square yards of muzzle flash and noise. One of them, Private First Class Nash Phillips of C Company, lost a hand in the fighting that night and never forgot what he saw at the guns. Years later, he summed it up in a single image. Basilone was barefoot, and his eyes were red as embers.

Barefoot because in the middle of the fight he had kicked off his shoes to move faster through the mud, and he kept running along the line without them for the rest of the night, because the guns had developed a new problem, in fact two at once: ammunition and water.

Ammunition belts were being used faster than they could be brought forward, and the supply route to the rear had been cut by Japanese soldiers who had slipped behind the forward positions. So Basilone did the other thing his citation would later note. He left the guns, fought his way across ground the enemy now roamed freely, reached the ammunition, carried the belts himself, and did it again and again so the guns would never fall silent for lack of something to fire.

Every trip meant crossing open, contested ground in the dark, loaded down with ammunition belts, muzzle flashes tearing the night around him with no guarantee of coming back, and still he made those trips.

Then there was the water problem. The cooling jackets had run dry or nearly dry, and a water-cooled weapon with a dry jacket is a weapon with only days left. No clean water remained for the purpose, so the Marines did the only thing possible. They opened the jackets and refilled them with whatever they had, and when they found no alternative, they urinated into them. Anything to get water back around those barrels and keep them working.

It is not a heroic image, a man relieving himself into his machine gun in the pitch dark. It is better than merely heroic. It is the reality of holding a defensive line when the only alternative is being overrun, exactly the kind of detail movies cut in the editing room.

The guns kept firing. By 5 a.m. that morning, soldiers of the 3rd Battalion, 164th Infantry Regiment began arriving to reinforce the line. They were not Marines. They were National Guardsmen from North Dakota, part of the Americal Division, and they had moved through the dark and rain and went straight into the fight, passing ammunition, plugging gaps, and adding their rifles to the guns.

As the sky turned gray, the attack had faded in front of the line. In front of the position Basilone had defended, the ground told the whole story. Bodies lay in the grass and churned mud, in the postures men fall into when a machine gun catches them in the open. Around the single gun he had worked himself, a later count estimated 38 enemy dead.

Of his two machine gun sections, Basilone and two other men were the only ones still standing at the end. The line had held. The airfield stayed American, and the planes on it would fly that morning because the Sendai Division was not finished yet.

During October 25, Marines and North Dakota infantry hunted down pockets of Japanese soldiers who had slipped behind the line, killing more than a hundred of them in the sweep. Maruyama, unwilling to admit his attack had already broken, ordered it renewed after dark.

The second night was a grim repeat of the first, with fresh troops fed into the same grinder. The 16th Infantry Regiment, held in reserve until then, entered the fight alongside what was left of the 29th, and the attack again ran into a defensive line full of machine guns and mortars, backed by artillery that had already registered every approach.

Just before dawn, the commander of the 29th Infantry, Colonel Masajiro Furumiya, cut through the American line with about 100 men, his headquarters staff, and the regimental flag. For a few hours they held a shallow pocket inside the defensive perimeter, then Marines closed it and destroyed most of those inside. Rather than let the regimental flag fall into American hands, Furumiya ordered it burned, and he was killed himself.

By 8 a.m. the following morning, Hyakutake canceled the attack entirely.

A hard day's march to the west, on another barren ridge, a separate part of the same battle played out on one of those nights, and it is worth pausing on because it proves Basilone's stand was not a one-off event by a single exceptional man.

Platoon Sergeant Mitchell Paige of the 2nd Battalion, 7th Marines, watched his machine gun section get destroyed entirely as Japanese troops crossed the top of the ridge. Paige moved from one gun to another along that line, firing each in turn to convince the enemy the position was still fully manned. When dawn broke, he hugged a gun hot as embers and led a bayonet charge down the slope.

Paige had trained his men to strip and reassemble the water-cooled machine gun blindfolded, on the theory that the night you really need the weapon is the night you will not be able to see it. He turned out to be right. Paige received the Medal of Honor for that ridge, the same award Basilone would receive for his.

Two sergeants, two ridges, one battle, and the same water-cooled guns at the center of both.

For the Japanese, the failure was catastrophic, and their own records are the clearest measure of what those weapons actually did. Maruyama began his night confident he would take the airfield. The news that reached him came in sequence, and each report was worse than the last. First, the attack was succeeding. Then his forward units in the dark mistook an empty field for the airstrip. Then the 29th Regiment was shattered and its flag was lost. There was not much left to say after that.

The left wing commander, Major General Yumio Nasu, had been killed. The commanders of both regiments that attacked the southern line were also killed. The Sendai Division, among the best infantry units in the Imperial Japanese Army, had marched a week through the jungle, starved to reach its positions, and then broken against a defensive line it could not penetrate.

One Japanese officer, after losing his regimental flag, wrote a final line in his diary about repaying his borrowed life, then ended it by his own hand. Across the whole battle, Japanese losses reached into the thousands. American dead were counted in the dozens. Those are the simple arithmetic of a water-cooled machine gun, and behind it a man who refused to leave it.

For the survivors of the Sendai Division, the ordeal was not over. They had to retrace their steps along the same brutal trail they had cut on the way in, carrying their wounded, without food, through jungle that had nearly killed them once already. Many of them did not make it out alive. The division that set out to take Henderson Field came back to the hills a broken force, and it never again mounted a serious attack on the airfield. The last real chance to storm that strip died in the grass in front of the southern wire.

Now, the truth, because this is not a movie account. You may have heard that John Basilone held off the Japanese alone for three days and three nights and wiped out an entire regiment by himself. That is the legend, and it grew from real roots.

The soldier who fought beside him, Nash Phillips, remembered it as three days and nights without sleep or food, and to a wounded man who had lost track of time, it certainly felt that long. But the savage fighting in Basilone's sector was the product of one terrible night, October 24 into October 25, followed by a second night of attacks along the wider line.

It was one night, not three, and Basilone did not fight it alone. He led two machine gun sections. Other Marines fed those guns, fired them, and died beside them. The North Dakota Guardsmen arrived in the dark and joined the fight. Mortar crews and the artillery batteries around the airfield killed larger numbers than any single machine gun could. The thousands of Japanese dead were spread along the whole battle, not stacked inside one man's field of fire.

His Medal of Honor citation describes it accurately. It credits him with contributing in large measure to the near annihilation of a Japanese regiment. The word "contributing" carries all the weight, and it is the honest word, because it means he did not do it alone.

The real story is not smaller than the legend. It is harder, because it means the line held on the shoulders of many men whose names were never known. Put simply, Basilone was holding a keystone when the line nearly came apart.

The weapon had its limits too, and the men who used it knew them better than anyone. It was heavy, more than 90 pounds with gun, tripod, water, and ammunition. Moving it was grueling and repositioning it was slow, which is exactly what made dragging it along the line in the dark a stunning feat of physical strength.

The boiling cooling jacket gave off steam that could reveal the gun's position to an enemy mortar crew at night. And the whole system depended for its survival on water, the one resource that ran out at the worst possible times, driving Marines to fill the jackets with their own urine just to keep the weapons running.

A gun that can fire forever is only as good as the water in the jackets and the men willing to keep feeding it. That night, in that sector, the Marines kept the gun fed, barely.

John Basilone received the Medal of Honor for what he did on Guadalcanal, and he was the first enlisted Marine to receive it in World War II. He was decorated in Australia in the spring of 1943, and then the Marine Corps did the obvious thing with a genuine national hero. They sent him home to sell war bonds.

He drew crowds wherever he went. His hometown of Raritan held a parade for him down Main Street. He could have spent the rest of the war safe and celebrated, training recruits far from any beach, shaking hands for photographs. Instead, he asked to go back.

He turned down a promotion and a safe posting because he did not want to leave the kind of men he had fought beside on Guadalcanal. When people overstated the medal, he gave the credit to others. He said only part of the medal belonged to him, and insisted the rest belonged to the buddies still over there.

On February 19, 1945, Sergeant John Basilone landed on the black sand of Iwo Jima with the Fifth Marine Division. Within hours, he destroyed a Japanese blockhouse and guided a tank through a minefield under heavy fire. Then a mortar shell struck near the edge of the airfield, and "Manila John" was gone. He was 28 years old.

He is buried now in Arlington National Cemetery. Two U.S. Navy destroyers have since carried his name, the most recent still at sea. On its battle flag, a pair of water-cooled machine guns is embroidered crossed.

Go back one last time to that airfield in the rain on the night of October 24, 1942. A thin line of exhausted men, a division coming out of the dark jungle to retake the airstrip, and two machine guns that never stopped firing because a sergeant from New Jersey kept feeding them ammunition and water with his bare hands all night long.

The Japanese came to take Henderson Field. Nobody warned them about the water.
