The Brutal Truth About America’s Combat Shotguns in Vietnam

In 1918, the German Empire threatened to execute every American soldier caught carrying a shotgun. This from the nation that had invented poison gas at Ypres, that had burned men alive with flamethrowers at Verdun, that had sent U-boats to sink hospital ships in the North Atlantic, but the shotgun, according to Berlin, was a step too far.

24 years later, in the black volcanic caves of a Pacific island most Americans could not find on a map, the Empire of Japan would make the exact same threat. And a five-page memorandum written by an Army lawyer the War Department had already discarded would be the only thing standing between a young Marine from Alabama and a Japanese firing squad.

This is a story your history books never told you. And it begins on the night of October 24th, 1942, in a place called Guadalcanal, where the jungle did not sleep. It breathed. It watched. And it waited. Private First Class Eugene Sledge was not there yet. He was still a boy in Mobile, Alabama, 18 years old, reading newspaper headlines about a place he could not pronounce.

He would not step onto a Pacific beach for another 2 years. But the men who fought that October night, the Marines of the 1st Division dug into the mud around Henderson Field. They would leave behind something Sledge would inherit, a weapon, a reputation, and a question that had haunted American soldiers for a quarter of a century. The question was simple.

Was the shotgun too cruel for war? Rain fell in sheets across the perimeter that night. The Marines could not see 10 ft in front of their positions. The vegetation on Guadalcanal was what soldiers would later call primary jungle, triple canopy forest, vines thick as a man’s wrist, undergrowth so dense that visibility, even in daylight, could shrink to 3 m.

At night, in the rain, it shrank to nothing. The Marines heard them first. Voices, hundreds of voices. The Sendai Regiment of the Imperial Japanese Army was moving through the darkness, and they were not trying to be quiet anymore. They were screaming, “Banzai!” “Banzai!” The word rolled through the jungle like thunder.

Then the wire in front of the Marine positions began to shake. A Marine gunner named John Basilone would earn the Medal of Honor that night, feeding belts into machine guns until the barrels glowed. But, further down the line, >> [clears throat] >> in the places where the jungle pressed closest to the American foxholes, other Marines were reaching for a different weapon.

It was old, older than most of the men holding it. The Winchester Model 1897, a pump-action shotgun designed by John Browning in the closing years of the 19th century. Some of the guns in Marine hands that night had been manufactured before their owners were born. The bluing had worn thin. The wooden stocks were dark with sweat and rain.

But, when a Japanese soldier came screaming out of the vegetation at 3 m, the the Model 1897 did what no rifle in the world could do. It did not miss. A single pull of the trigger sent nine lead pellets, each 1/3 of an inch across, spreading through the darkness in a widening cone. Nine simultaneous impacts, the equivalent at close range of nine handguns firing at once.

The Japanese soldier who charged that gun did not stumble. He did not stagger. He simply stopped existing as a coordinated human being. The Marines who fired those weapons did not know that they were at that exact moment at the center of a diplomatic crisis. They did not know that in Tokyo, in Washington, in the neutral halls of the Swiss Embassy that carried messages between two empires at war.

Uh lawyers and diplo- diplomats were arguing about whether the very weapon in their hands was a war crime. The argument was not new. It had started 24 years earlier in the trenches of France. In the autumn of 1918 as the German army crumbled on the Western Front, the Imperial German government did something that historians would remember as one of the strangest diplomatic protests of the First World War.

They filed a formal complaint against the United States. Not about American tanks. Not about American artillery. Not about the massive American army pouring into France at a rate of 10,000 men a day. They complained about a shotgun. The Winchester Model 1897, the same weapon Marines would carry at Guadalcanal, had been fitted with a bayonet lug and a ventilated heat shield and issued to American soldiers as the trench gun.

In the close, muddy horror of trench warfare, it was devastating. American soldiers used it to clear German trenches so efficiently that German commanders panicked. On September 19th, 1918, the German government issued a cable. Any American soldier captured with a shotgun or with shotgun ammunition in his possession would be executed.

They cited Article 23, paragraph E, of the Hague Convention of 1907. The article prohibited arms calculated to cause unnecessary suffering. This came from the nation that had introduced chlorine gas at Ypres, that had deployed flamethrowers at Verdun, that had waged unrestricted submarine warfare across the Atlantic. But the shotgun, according to Germany, was a step too far.

The American response was written by a lawyer. His name was Samuel Tilden Ansell. In 1918, he was a brigadier general and the acting judge advocate general of the United States Army. He was 42 years old, a graduate of West Point, a career military lawyer with a reputation for arguing hard and losing gracefully.

He sat down at his desk in Washington and produced a five-page rebuttal. His argument was simple. Article 23, paragraph E, was not about efficiency in killing. It was about cruelty. It was about weapons designed to inflict wounds that could not be treated, that caused prolonged agony, that served no military purpose beyond suffering.

The double-aught buckshot pellet, Ansell wrote, measured eight 4 mm across. That was scarcely larger than a standard rifle bullet. It was smaller than the projectiles fired by German machine guns. It caused wounds that were, in medical terms, no worse than any other lead projectile of similar size. The German protest, Ansell concluded, was without legal merit.

Coming from an enemy that had introduced poison gas to modern warfare, it was destitute of all good faith. Secretary of State Robert Lansing sent the reply through neutral channels. And he added a warning. If Germany executed a single American prisoner for carrying a shotgun, the United States would make such reprisals as would best protect American forces.

Germany never answered. No American soldier was ever executed for carrying a Winchester Model 1897 in the First World War. The war ended 44 days after the German protest was filed. But Samuel Ansell’s five-page memorandum did not die with the armistice. It went into a filing cabinet in the office of the Judge Advocate General.

It sat there through the 1920s, through the Great Depression, through the rise of new empires and new wars. It waited. And in the spring of 1942, someone pulled it out. The war in the Pacific was six months old. American Marines were fighting on Guadalcanal. American shotguns refurbished from World War I stocks and newly manufactured Winchester Model 12s were arriving in the jungle by the thousands.

And the Imperial Japanese government had noticed. Through the government of Switzerland, which handled diplomatic communications between the belligerents, Japan filed a protest. The language was almost identical to the German protest of 1918. The shotgun, Japan declared, violated Article 23, paragraph E of the Hague Convention.

American soldiers captured with such weapons would face the harshest consequences. The protest landed on the desk of the United States Department of State. It was routed to lawyers. Someone remembered Ansell. The 1918 memorandum was retrieved from its filing cabinet. Its arguments were dusted off and updated. The response the United States would send to Japan through the Swiss legation in Bern would draw directly from a document written by a man who had been arguing with a different enemy in a different war. The lawyers who read Ansell’s

memorandum in 1942 did not know something else about its author. Samuel Ansell had been forced out of the army in 1919. He had spent the last year of his tenure as Judge Advocate General fighting a bitter public battle with the Secretary of War over reform of the military justice system. Ansel believed that courts-martial were fundamentally unfair to enlisted soldiers. He had lost.

He had been demoted, sidelined, and eventually pushed into private practice. The man whose legal reasoning would now protect Marines on Guadalcanal had been discarded by the same army that was about to use his words. Eugene Sledge did not know any of this. In the spring of 1942, he was finishing his sophomore year at Marion Military Institute.

He was thin, quiet, the son of a doctor. He had been raised on stories of the American Civil War told by grandfathers who remembered it. He wanted to enlist immediately after Pearl Harbor. His parents begged him to wait, to finish college, to consider officer training. He waited. He resented every day of the waiting.

By the time Sledge would finally reach the Pacific in September of 1944, the shotgun would already be a legend among Marines. The men who had carried Winchester Model 1897s at Guadalcanal, the survivors, would speak of them the way old soldiers had once spoken of muskets. They would describe the way the weapon felt in close combat.

The way it did not require aim, only direction. The way it made distance irrelevant. They would also describe something else. Something the recruiting posters did not mention. The way a shotgun sounded inside a jungle at night. The way the muzzle flash blinded the shooter for critical seconds. The way the recoil absorbed a hundred times over the course of a firefight left a man’s shoulder black with bruises that took weeks to fade.

And they would describe the fear, not just the fear of the enemy. The fear of what the enemy would do if you were captured with the weapon in your hands. The Marines at Guadalcanal in October of 1942 did not know that a Japanese diplomatic protest was working its way through Swiss channels. They did not know that lawyers in Washington were reading a memorandum written in 1918.

They knew only that they had a weapon that worked in the jungle. A weapon that closed the gap between a rifle designed for 300-m engagements and a war being fought at 3 m. They knew that when the wire began to shake and the voices began to scream, the shotgun was what they wanted in their hands. They did not know that men in suits half a world away were deciding whether that weapon would cost them their lives if they were ever taken alive.

The rain kept falling on Guadalcanal. The Sendai regiment kept coming and somewhere in a filing cabinet in Washington, a five-page memorandum written by a disgraced army lawyer was about to save more American lives than its author would ever know. The story of that memorandum and of the men who would live and die by its arguments was only beginning.

The document arrived to Washington in the spring of 1942 carried in a diplomatic pouch from the Swiss legation in Bern. It was written in formal Japanese, translated into French by Swiss diplomats, and then rendered into English by clerks at the State Department. By the time it reached the desk of Cordell Hull, Secretary of State, it had passed through three languages and four sets of hands, but its meaning had not changed.

Hull was 70 years old that spring. He had served as Secretary of State for 9 years. He was a tall, gaunt Tennessean with white hair and a slow, deliberate manner of speaking. He had spent the last decade trying to prevent the war that was now consuming his desk. He read the Japanese protest twice. Then he called for the lawyers.

The protest was specific. The Imperial Japanese government had received reports that American Marines in the Pacific were using shotguns against Japanese soldiers. Such weapons, Japan declared, violated Article 23, paragraph E, of the Hague Convention of 1907. Any American serviceman captured with a shotgun or shotgun ammunition would be treated accordingly.

The word accordingly was not defined. It did not need to be. The lawyers went into the archives. They pulled files that had not been opened in 24 years. And they found Samuel Ansell’s five-page memorandum from 1918, still crisp in its folder, still waiting. They read it. They updated the citations. They added references to the newer Geneva Conventions.

But the core argument remained exactly as Ansell had written it in the last months of the First World War. The double-aught buckshot pellet measured eight 4 mm. It was no larger than a rifle bullet. It was smaller than the projectiles fired [snorts] by heavy machine guns. It caused wounds that were, in medical terms, indistinguishable from any other lead projectile of similar size.

Article 23, paragraph E, prohibited weapons of unnecessary suffering. The shotgun caused no more suffering than any other firearm on the battlefield. The American response went back through Swiss channels. It arrived in Tokyo in the summer of 1942. Japan did not reply. Japan did not need to because in the caves of the Pacific, the answer was already being written in blood.

Eugene Sledge stepped onto the beach at Peleliu on September 15th, 1944. He was 20 years old. He carried a mortar. He was assigned to Company K, 3rd Battalion, 5th Marines, 1st Marine Division. He had trained for a year. He had crossed the Pacific in a troopship. He had listened to older Marines, veterans of Guadalcanal and Cape Gloucester, describe what he was about to see.

Nothing they told him prepared him for what he saw. Peleliu was 6 square miles of coral rock, jungle, and heat. The temperature on the island reached 115° F in the shade. There was no shade. The Japanese garrison, roughly 11,000 strong, under Colonel Kunio Nakagawa, had spent months preparing. They had turned the coral ridges of the Umurbrogol Mountains into a honeycomb, hundreds of interconnected caves and tunnels, firing [snorts] positions that could not be seen from the air, could not be spotted from the ground,

could not be attacked with artillery. The Marines were told the battle would last 4 days. It lasted 73. Sledge learned quickly what the Marines who had fought at Guadalcanal already knew. In the caves of Peleliu, the rifle was not the primary weapon. The flamethrower was. The satchel charge was. And when a Marine had to go into a cave, into the darkness, into a space where a Japanese soldier might be waiting 3 ft away with a sword or a rifle or a grenade, the weapon of choice was the shotgun, the Winchester Model 12

and the Model 1897. Sledge watched Marines from other companies carry them into the caves. He watched them come back out, some of them with the shotguns still in their hands and the barrels warm. He watched them come back out, some of them on stretchers. He watched some of them not come back out at all.

The physics of a cave engagement were brutal uh in their simplicity. A Japanese soldier hiding in the darkness had one advantage. He knew where the Marine would come from. The Marine entering from bright sunlight into total blackness could see nothing for the first several seconds. In those seconds a man died. The shotgun did not require sight.

A Marine entering a cave could fire a shotgun into the darkness in front of him. And the spreading cone of buckshot would fill the space. Nine pellets. Then a second shot. Then a third. In two seconds a trained Marine could put 27 projectiles into a cave the size of a small room. He did not have to aim. He only had to point.

The Japanese knew this and they adapted. Marine intelligence reports from Peleliu documented a discovery that unsettled the men who read them. Japanese soldiers in the caves of the Umurbrogol were carrying shotguns of their own. Some were captured American weapons taken from Bataan and Corregidor in 1942 when American and Filipino forces had surrendered.

Others were Japanese-made sporting shotguns from small domestic manufacturers produced for the pre-war civilian market. Belgian and other European sporting weapons imported before the war converted for military use. The Japanese government had protested the American shotgun as a war crime. The Japanese army was using shotguns in the same caves.

The contradiction was never publicly acknowledged by Tokyo. It never needed to be. Cordell Hull’s State Department did not respond to Japanese diplomatic protests with press releases. The war would be decided by men in caves, not by men at podiums. Sledge would later write about what happened in the Umurbrogol. His hands shook, he remembered, for weeks afterward.

Not from fear of the Japanese, from something harder to explain. He wrote about a Marine he watched fire a Winchester Model 12 inside a cave. The muzzle flash in the enclosed space was blinding. The concussion of the shot in the tight rock chamber left the shooter deaf for hours. Some Marines came out of caves with blood running from their ears.

The shotgun that killed the enemy also damaged the man who fired it. Sledge wrote that the men who volunteered to enter the caves with shotguns were changed by it. They came out different, queerer. They stopped talking about home, they stopped talking about anything. The First Marine Division would take Peleliu at a cost of 6,500 casualties.

The Fifth Marines, Sledge’s regiment, would lose 43% of its men. The battle would be judged in later years one of the most strategically pointless of the war. The island had no meaningful military value. The airfield built there was never used against Japan. But the Marines who fought there, the ones who lived, carried something out of the caves that they would never put down.

Eugene Sledge carried it for 35 years before he could bring himself to write about it. His memoir, uh published in 1981, would be titled With the Old Breed. It would become one of the most important American accounts of ground combat ever written. He would write about many things. The heat, the stench, the maggots, the way a man’s mind protected itself by shutting down parts of itself permanently.

He would also write about the shotgun. He would write about it not as a weapon of glory, not as a symbol of American ingenuity. He would write about it as a tool, a tool that worked, a tool that kept Marines alive in a place where nothing else could. And in the archives of the State Department, in a filing cabinet that would not be opened again for decades, Samuel Ansel’s memorandum sat quietly.

It had done its work. No American Marine had been executed for [snorts] carrying a shotgun in the Pacific. Not because Japan had accepted the American argument, but because Japan in the end had never captured enough Marines alive to matter. The men who went into the caves rarely came out as prisoners. They came out as Marines.

Or they did not come out at all. The war moved on. Uh from Peleliu to Iwo Jima. From Iwo Jima to Okinawa. The shotgun moved with it. And the question that Germany had asked in 1918 and that Japan had asked in 1942 still had no formal answer. It would not receive one. The answer would be written not in international law, but in the memories of the men who had carried these weapons.

And those men the ones who lived were about to come home. The war ended on the deck of a battleship. On the morning of September 2nd, 1945, the USS Missouri sat at anchor in Tokyo Bay. Japanese officials in top hats and morning coats climbed the gangway. They signed the instrument of surrender. General Douglas MacArthur signed on behalf of the Allied powers.

The ceremony took 23 minutes. No one mentioned the shotgun. The Japanese diplomatic protest of 1942 was never withdrawn. It was never formally answered by Tokyo after Cordell Hull’s response, it simply ceased to matter. The government that had filed it no longer existed in the form that had signed it.

The empire that had threatened American prisoners was gone. The legal question remained open. It remains open today. But the men who had lived it did not care about legal questions anymore. Eugene Sledge came home to Mobile, Alabama in the spring of 1946. He was 22 years old. He weighed less than he had when he enlisted.

His mother met him at the train station. She would later say that the boy who had left was not the man who came back. He did not speak about Peleliu. He did not speak about Okinawa. He did not speak about the caves. He enrolled at Alabama Polytechnic Institute. He studied biology. He married a woman named Jeanne Arsenault in the early 1950s.

He became a professor. He taught ornithology, the study of birds, at the University of Montevallo. He kept a garden. He raised two sons. For 35 years, he did not write down what he had seen. The nightmares did not stop. He would later admit that he woke sometimes still smelling the caves, still hearing the sound of a Winchester Model 12 fired inside coral rock, still seeing the faces of men from company K who had gone into the darkness and had not come back.

He wrote it down finally in the late 1970s. He wrote it in longhand on yellow legal pads in the evenings after teaching. His wife typed the manuscript. He was not trying to publish it. He was trying to explain it to his sons. The manuscript became With the Old Breed. It was published in 1981. It was reviewed quietly, praised carefully, and then over the following decades recognized as one of the most honest accounts of ground combat ever written by an American. Sledge died in 2001.

He was 77 years old. He never spoke publicly about the shotgun. But he had written about it. And what he had written, other men had read. And other men had rem- remembered. The United States Marine Corps did not put the shotgun away after the Second World War. The lessons of Guadalcanal and Peleliu and Okinawa were absorbed into Marine doctrine.

In every jungle, in every city, in every close-quarters environment where American Marines would fight in the second half of the 20th century the shotgun would be there. Not as the primary weapon. Never as that. But as the weapon a squad leader could reach for when the fight came within 10 m, when the rifle became a liability, when the enemy was close enough to touch, the Winchester Model 12 remained in service.

The Ithaca Model 37, a pump action shotgun, first manufactured in 1937, and refined during the Pacific War, entered widespread military use. The Remington 870, developed in 1950, joined them. And 20 years after Eugene Sledge came home from Peleliu, the same weapons, the same design principles, the same close-quarters logic that had been proven in the caves of the Umurbrogol, would be carried by young Americans into a different jungle.

The jungle in Vietnam. The Marines who went ashore at Da Nang in 1965 did not know the history of the Ansel memorandum. They did not know the story of the German protest of 1918 or the Japanese protest of 1942. They knew only that they had been issued shotguns. That the older sergeants told them quietly that these weapons were the ones you wanted when the vegetation closed in. They were right.

Brigadier General S.L.A. Marshall, the Army’s chief combat historian, would go to Vietnam and document what had already been documented at Peleliu. Most firefights happened at ranges under 30 m. Most contacts began at ranges under 15. >> [clears throat] >> In the triple canopy jungles of Southeast Asia, the rifle designed for 300-m engagements was failing.

And the weapon that Germany had called too cruel for warfare, that Japan had called a violation of international law, was once again the most effective infantry weapon in the American arsenal. The pattern held. The controversy had died. By the time American Marines were fighting in Hue City in 1968, the shotgun was so completely accepted as a legitimate weapon of war that no nation on Earth protested its use, not the North Vietnamese, not the Soviet Union, not the international press that scrutinized every other aspect of American military conduct. The men who

had carried Winchester Model 1897s at Guadalcanal had won that argument without ever knowing they were fighting it. Eugene Sledge lived long enough to see it. He watched the Vietnam War on television. He watched young Marines, his sons’ age, go into jungles that looked to him unbearably familiar.

He did not comment publicly. He rarely commented on anything publicly. But those who knew him said that he grieved quietly for every one of them. He knew what they were carrying, not just the weapons, the weight that came after, the Ansell memorandums sits today in the archives of the United States Army Judge Advocate General’s Corps.

Samuel Ansell died in 1954. He was 78 years old. The obituaries at the time mentioned his legal career, his advocacy for military justice reform, his years in private practice. They did not mention the five pages he had written in 1918. He never knew that his argument uh filed away in a cabinet at the end of the First World War had been retrieved during the Second.

He never knew that it had protected the Marines at Peleliu. He never knew that his words, written to answer a German protest that arrived 44 days before the armistice, had outlived him and [clears throat] the wars he could not have imagined. His memorandum still governs the dots legal status of combat shotguns in United States military doctrine.

It has never been overturned. It has never been seriously challenged. Every NATO nation, including modern Germany, now fields combat shotguns as standard equipment. The weapon that was called too cruel for war became one of the most universally accepted weapons in the modern military arsenal.

Not because the argument was settled in a courtroom, because it was settled in the mud, in the caves, in the jungles, by men who had no interest in what lawyers or diplomats had to say. Who knew only that when the enemy was 3 m away and the vegetation was too thick to see through, there was one weapon that would keep them alive.

Eugene Sledge, in the final pages of With the Old Breed, wrote a sentence that has been quoted many times since. He wrote that war was brutish, inglorious, and a terrible waste. He wrote that combat leaves indelible marks on those who are forced to endure it. He did not write about victory. He did not write about the shotgun. He wrote about the men.

The ones who came home carrying weapons they would never speak of. The ones who came home carrying memories they could not put down. The ones who lived quietly in Alabama and Ohio and Pennsylvania and California for the rest of the 20th century and who took their stories with them when they died.

Some of those men are still alive today. They are in their late 90s now. They live in nursing homes and small houses and with families who have never asked and who they have never told. They know what the shotgun did. They know what it cost. And they know better than any lawyer or diplomat or historian that the answer to the question Germany asked in 1918 and Japan asked in 1942 was never really a legal question at all.

It was a question about what war does to the men who fight it. And the answer in the end was written not in memoranda but in silence.
