😱 How One Marine’s “Forbidden” Brig Trick Made 40 Thieves Stop 3,000-Man Banzai Charge 😱 – HTT

How One Marine’s “Forbidden” Brig Trick Made 40 Thieves Stop 3,000-Man Banzai Charge

At 0900 on September 27th, 1942, Lieutenant Colonel William Whailing stood at the edge of Henderson Field on Guadalcanal, observing as four Marines carried a stretcher toward the aid station.

The grim reality of war was starkly evident; a 22-year-old Marine had been killed during his third patrol that week, dead before his unit could locate the Japanese position.

Three more stretchers followed, a harrowing reminder of the deadly jungle that had consumed a seven-man patrol that morning.

Only four of those men returned, a clear indication that the Japanese forces had a firm grip on the jungle terrain.

Two months into the Guadalcanal campaign, Marine patrols were walking into ambushes they never saw coming.

In just three weeks, 17 patrols had been wiped out, and the Japanese moved through the dense vegetation like ghosts.

Marines, trained for frontal assaults, struggled to see an enemy soldier even 10 feet away.

Enemy snipers picked off officers with deadly precision, while machine gun nests remained hidden until entire squads walked past, unleashing a hail of gunfire from behind cover.

Whailing recognized that this pattern would lead to complete annihilation.

The First Marine Division had lost 400 men to Japanese ambushes in September alone, and it was clear that standard infantry tactics were ineffective in jungle warfare.

They needed something different, something the Japanese would not expect.

Two days earlier, Whailing had been relieved of his command as executive officer of the Fifth Marine Regiment—not due to combat failure, but because of personality conflicts with his commanding officer.

Most officers in his position would have been shipped back to the United States, but Colonel Gerald Thomas, the divisional chief of staff, recognized Whailing’s potential.

A World War I veteran and silver star recipient at San Miguel, Whailing was an expert marksman who competed in the 1924 Olympics.

Most importantly, he understood fieldcraft better than any officer in the division.

Thomas kept him on Guadalcanal and tasked him with solving their jungle problem.

Whailing spent three days observing patrols leave and counting how many returned.

The mathematics were brutal; at this rate, the division would run out of infantrymen before the Japanese ran out of jungle.

He needed men who could hunt the hunters—Marines who understood stalking, could read terrain, move silently, and kill without being seen.

On September 29th, Whailing walked into General Alexander Vandergrift’s command tent with a bold proposal.

He suggested organizing a scout sniper unit composed of 100 volunteers, handpicked from Marines with hunting backgrounds, outdoorsmen, and skilled marksmen.

The plan was to train them in reconnaissance and ambush tactics, sending them into the jungle in small teams to gather intelligence and eliminate Japanese positions before regular patrols advanced.

Vandergrift approved immediately.

The general had studied Lieutenant Colonel Robert Rogers and his Ranger tactics from the French and Indian War, where small mobile units operated independently behind enemy lines.

The idea fit perfectly with their desperate situation on Guadalcanal.

Whailing had one week to find his men and start training.

Back to Whailing.

He began reading service records that night, searching for specific markers: expert rifle qualifications, rural backgrounds, hunting experience, and disciplinary records that indicated independence—not cowardice.

He sought men who thought for themselves, the kind of Marines who often got into trouble for questioning orders but always completed their missions.

By October 1st, Whailing had identified 43 candidates.

He called them to a briefing at 0600 on October 2nd, informing them that the assignment was voluntary and that the casualty rate for reconnaissance work ran above 50%.

He explained they would operate in teams of two or three, sometimes for days behind Japanese lines, with no backup and no extraction if things went wrong.

41 volunteered immediately.

Only two walked away.

Whailing looked at the men standing in front of him.

Most were 20 years old or younger, and half had been in combat for less than two months.

But they had something the regular infantry did not—they wanted to hunt.

Whailing was about to teach them how to become the most feared unit the Japanese would face in the Pacific War.

His training would create a template for future operations.

Two years later, another Marine officer would use Whailing’s methods to build an even more notorious unit, adding one unusual requirement to his recruitment process—a requirement that would shock the entire Marine Corps and create a legend that lasted 80 years.

Whailing started training on October 3rd.

No manuals existed for what he was building; the Marine Corps had disbanded its scout sniper program after World War I.

Everything Whailing knew came from experience—24 years in the Corps, jungle patrol in Nicaragua, and French battlefields, where he learned that invisible soldiers lived longer than brave ones.

The first lesson was silence.

Whailing took his volunteers into the jungle west of Henderson Field and instructed them to walk 100 yards without making noise.

Every man failed.

Equipment rattled, boots cracked branches, and canteens clinked against rifles.

The jungle amplified every sound.

He made them do it again, removing everything that made noise.

He taped down metal parts, wrapped cloth around canteen hooks, and had them wear soft-soled boots instead of standard issue.

After three days, half the men could move through dense vegetation without alerting Japanese positions 200 yards away.

Marksmanship came next.

Most Marines could hit targets at 300 yards on a rifle range, but rifle ranges did not have wind, rain, or targets that shot back.

Whailing taught them to estimate distance by terrain features, judge wind by watching vegetation, and account for how humidity affected bullet trajectory.

He made them fire from uncomfortable positions—uphill, downhill, lying in mud, crouched behind cover that barely concealed them.

By October 10th, his best shooters could kill Japanese soldiers at 400 yards with iron sights.

The hard part was teaching them to think differently.

Regular Marine infantry worked in squads of 12 men, with a clear chain of command where orders flowed down from officers.

Initiative was discouraged.

Whailing needed the opposite: teams of two or three operating independently for days, making tactical decisions without asking permission.

He trained them in map reading and terrain analysis, identifying good ambush positions, sketching enemy fortifications, and estimating troop strength from campfire smoke and foot traffic—skills that regular infantry never learned because officers did that thinking for them.

On October 13th, Whailing received orders from General Vandergrift.

The division was planning an offensive across the Matanakau River, where Japanese forces had dug in on the western side.

Machine gun nests covered every approach, and artillery positions were hidden in the jungle canopy.

Regular patrols had been slaughtered trying to find them, and Vandergrift wanted Whailing to take his partially trained unit to locate Japanese positions before the offensive began.

Whailing selected eight men, split them into four teams, gave each team a sector to scout, and instructed them to avoid contact if possible, gathering intelligence and returning.

If they got pinned down, they were on their own; the division could not afford to lose more men looking for lost scouts.

The first team left at 0400 on October 14th.

Two Marines, both from Montana and experienced elk hunters, moved west along the Matanakau River for three hours and found a Japanese artillery position at 0715.

Four Type 92 Howitzers were hidden under camouflage netting, guarded by 60 soldiers.

They sketched the position, counted ammunition crates, and returned by noon.

The second team discovered a machine gun nest overlooking a river crossing, while the third team mapped Japanese patrol routes.

The fourth team encountered trouble while mapping a trail network; a Japanese patrol appeared, five soldiers just 50 yards away.

The two Marines froze, waiting for the patrol to pass, but one Japanese soldier spotted them, raised his rifle, and prepared to fire.

The Marine closest to him fired first—a single shot.

The Japanese soldier dropped, but his four companions scattered and began shouting.

Within 30 seconds, whistles echoed through the jungle as enemy troops converged on the sound.

The two Marines ran, heading east toward Marine lines, with Japanese soldiers in pursuit.

The chase lasted 40 minutes.

The Marines reached friendly positions with 11 enemy soldiers just 200 yards behind them, but they brought back critical intelligence—detailed maps of Japanese positions along a two-mile front.

Information that regular patrols had failed to gather in two months of trying and that had cost dozens of Marine lives.

General Vandergrift examined the maps on October 15th and immediately altered his offensive plan.

Instead of a frontal assault, he would use the scout teams to guide flanking maneuvers around Japanese strong points.

Whailing’s unit had proven the concept worked, and now Vandergrift wanted more.

He instructed Whailing to expand, find another 60 volunteers, form a full company, and prepare for the largest Marine offensive of the Guadalcanal campaign.

The battle for the Matanakau was coming, and Whailing’s scout snipers would lead the way into the deadliest jungle fighting the Pacific War had seen.

The Matanakau offensive commenced at 0600 on October 6th, 1942.

Whailing’s scouts moved out 30 minutes before the main assault.

Their mission was simple: infiltrate Japanese lines, locate command posts and artillery positions, eliminate officers and radio operators, and create chaos before Marine infantry crossed the river.

Whailing organized his scouts into a special task force, combining them with the Third Battalion of the Second Marines.

The unit was officially called the composite battalion, but everyone else referred to it as the Whailing Group.

They crossed the Matanakau River three miles upstream from Japanese positions, moving through jungles so dense that visibility dropped to 20 feet.

With no trails, no maps, just compass bearings and intuition, they penetrated two miles behind Japanese lines without being detected by 0800.

The first engagement occurred at 0920 when a Whailing Group scout team spotted a Japanese command post tent with radio equipment.

Six officers were studying maps, and 15 soldiers provided security.

The scouts waited until the officers gathered for a briefing before opening fire from 200 yards away.

They killed four officers in the first volley, and the remaining Japanese soldiers scattered into the jungle, never discovering who shot them.

Thirty minutes later, another scout team eliminated a forward observer calling artillery strikes on Marine positions with a single shot from 300 yards.

The observer dropped, and artillery fire ceased.

Marine infantry advanced 600 yards before Japanese gunners realized their spotter was dead.

By noon, the Whailing Group had encircled Japanese positions west of the Matanakau.

Regular Marine battalions attacked from the east while scouts cut off retreat routes.

Japanese forces found themselves trapped between two forces, with no escape and no reinforcements.

The fighting lasted four days.

Between October 6th and October 9th, approximately 750 Japanese soldiers died in the encirclement, and the Fourth Infantry Regiment effectively ceased to exist as a combat unit.

Marine casualties were lighter than in any previous offensive, with 43 killed and 112 wounded.

General Vandergrift credited the scout snipers with changing the tactical situation through small teams gathering intelligence, eliminating key targets, and disrupting command and control.

The Japanese had not expected Marines to fight like this; they anticipated frontal assaults, not infiltration and ambush.

Whailing’s methods worked, but they came at a price.

On October 8th, Whailing sustained shrapnel from a mortar round.

While nothing critical, it was enough to put him in a field hospital for observation.

Infection set in three days later, and by October 15th, fever forced his evacuation to a hospital ship.

He spent the next four months recovering and missed the remainder of the Guadalcanal campaign, but his program survived.

The First Marine Division formally established scout sniper platoons in each infantry regiment, and the headquarters company received a dedicated reconnaissance section.

Training became standardized, and selection criteria were formalized.

Everything Whailing had created from scratch in September became official Marine Corps doctrine by December.

The division awarded him the Legion of Merit in February 1944.

The citation read that he organized a scout sniper detachment and supervised the training of selected groups in scouting, stalking, and ambush tactics, and that his instruction and expert knowledge of jungle warfare contributed immeasurably to the success achieved by Marine patrols.

Whailing never returned to Guadalcanal; instead, he took command of the First Marine Regiment in Australia, led them at Cape Gloucester, and eventually commanded the 29th Marines on Okinawa, where he earned the Navy Cross.

He retired as a major general in 1954.

But his real legacy was not the medals he earned; it was a concept—a template for how Marines could fight differently.

His program became the foundation for all Marine scout sniper operations throughout World War II, Korea, and Vietnam.

Every conflict where Marines needed eyes in places regular infantry could not go.

Two years after Whailing created his program, another Marine officer read his after-action reports, studied his training methods, and decided to build something even more aggressive—an elite platoon that would take Whailing’s ideas and add one controversial twist.

This officer did not want disciplined Marines; he wanted fighters, troublemakers—men who won brawls and ended up in the brig.

He was about to create the most legendary scout sniper unit of the Pacific War.

At 0700 on January 15th, 1944, First Lieutenant Frank Tachsky walked through the brig at Marine Corps Base Camp Tarawa in Hawaii.

At 29 years old, he was a combat veteran of Guadalcanal and Tarawa, looking for the worst Marines in the Second Marine Division.

He found them—18 men locked in cells for fighting, facing assault charges, insubordination, and destruction of property—the kind of disciplinary problems that got Marines dishonorably discharged.

However, Tachsky was not there to punish them; he was there to recruit them.

Three months earlier, Colonel James Risley had given Tachsky an unusual order: form an elite scout sniper platoon for the Sixth Marine Regiment.

He was to model it after British commandos and train 40 men in reconnaissance and long-range killing, but he was not to recruit from regular infantry.

Risley wanted something different—men who could not follow orders, men who thought for themselves, men who would survive behind enemy lines where rulebook tactics got you killed.

Tachsky understood the assignment.

He had read William Whailing’s after-action reports from Guadalcanal and studied how small teams of scouts disrupted Japanese operations.

But while Whailing had recruited hunters and outdoorsmen—disciplined men with fieldcraft skills—Tachsky wanted the opposite.

His selection criteria were simple: find Marines who won fights and ended up in the brig, ignoring the losers who went to the infirmary.

He explained his logic to skeptical officers.

“When two Marines fight, one wins and one loses. The loser goes to sick bay. The winner goes to the brig for assault. Standard Marine justice punishes the wrong man.

The winner proves he can handle himself; he proves he will not quit when things get violent.

That is the Marine I want on my team.”

The brig commander thought Tachsky was insane, telling him these men were troublemakers and criminals—the worst discipline cases in the division.

But Tachsky insisted that was exactly what he needed.

Over three weeks, he interviewed 47 Marines with disciplinary records, asking them why they fought, what they did before joining the Corps, and whether they could kill a man silently with a knife.

23 volunteered, while another 17 came from regular infantry—Marines with expert marksman ratings who had proven themselves at Tarawa.

By February 1st, Tachsky had his 40 men, officially calling them the scout sniper platoon of the Sixth Marine Regiment.

The nickname came later, after they started stealing everything not bolted down on the Big Island of Hawaii.

Training began in the jungle highlands near Hilo.

Tachsky used Whailing’s methods as a foundation—silent movement, long-range marksmanship, and map reading—but added hand-to-hand combat training, knife fighting, and garrote techniques, learning how to kill sentries without making noise.

He adapted British commando tactics for Pacific jungle warfare.

The platoon learned to live off the land, hunt wild boar, catch fish, and identify edible plants—survival skills for operating behind enemy lines where resupply was impossible.

They trained with piano wire garrotes, learning how to roll the wire in glue and crushed glass.

One Marine named Wild Bill Emer became infamous for rescuing wounded men from kill zones using nothing but a garrote and silence.

Equipment was a problem; the Marine Corps issued them World War I-era Springfield rifles, outdated rations, and no proper camouflage.

So they stole better gear, raiding Army supply depots at night to acquire newer weapons, canned food, whiskey, and even an Army captain’s jeep, which they repainted Marine green.

Back to the thieves.

The stealing became legendary.

Other Marine units dubbed them the 40 thieves—not as an insult, but as a mark of respect.

These men operated outside normal military constraints, taking what they needed to survive.

Officers looked the other way because Tachsky was building something unprecedented—a unit capable of hunting Japanese soldiers in their own territory.

By May 1944, the 40 thieves were ready.

Saipan was coming—15 square miles of volcanic rock and jungle, defended by 30,000 Japanese soldiers.

The first invasion of Japanese home territory was set, and high command expected 70% casualties in the first week.

The thieves would go in first, days before the main landing.

Their mission was simple: scout enemy positions, map defenses, kill officers, and survive long enough to guide the assault force through the bloodiest invasion of the Pacific War.

At 0530 on June 15th, 1944, Corporal Bill Canple crouched in a Higgins boat 300 yards off Saipan’s western shore.

At 21 years old, he was a member of the 40 thieves, watching naval bombardment tear apart the beach ahead.

The noise was deafening—16-inch guns from battleships, five-inch destroyer batteries, and rockets from landing craft.

The entire shoreline disappeared under a cloud of smoke and fire.

The Japanese were waiting.

The second and fourth Marine divisions hit the beach at 0840, with 8,000 Marines in the first wave.

Japanese artillery opened fire immediately, unleashing mortars and machine guns that zeroed in on landing zones.

Marines died before they even left their boats, bodies floating in the surf, and wounded men drowning in three feet of water.

The 40 thieves landed in the fourth wave, their mission different from that of regular infantry.

While line companies fought for the beaches, Tachsky’s platoon moved inland, seeking Japanese command posts, artillery positions, supply dumps, and targets that regular Marines would not reach for days.

By noon, the thieves had penetrated half a mile inland, finding themselves in dense sugarcane fields where visibility dropped to 10 feet—perfect terrain for ambush.

Japanese soldiers hid everywhere—in caves, underground bunkers, and spider holes covered with vegetation.

The first silent kill occurred at 1300 hours when two thieves were scouting a trail and spotted a Japanese radio operator alone, setting up antenna wire.

They approached from behind with a piano wire garrote, and the operator died without making a sound.

They took his maps and radio codes, leaving his body hidden in the sugarcane.

Two hours later, another team eliminated a three-man observation post using knives—no gunfire.

Japanese officers never knew their forward observers were dead, leading to uncoordinated artillery fire.

Marines advanced through gaps in defensive fire.

This was what Tachsky had trained them for: silent killing, operating independently, and making tactical decisions without orders.

The thieves moved through Japanese-controlled territory like ghosts while regular infantry engaged in set-piece battles.

On June 16th, Tachsky led a patrol to scout Mount Tipo Pale, a volcanic peak in central Saipan.

Intelligence reports indicated that Japanese forces were using the mountain as an observation post, directing artillery strikes on Marine positions.

Tachsky needed to find them.

The patrol climbed through jungle so thick that they used machetes, reaching the base of Mount Tipo Pale at 0900.

They discovered a trail leading up the slope, with fresh footprints and bicycle tracks.

The Japanese were using bicycles to transport supplies and troops down the mountain.

Tachsky positioned his best snipers along the trail—five men with Springfield rifles mounted with Unertl scopes—and instructed them to wait for targets.

By noon, Japanese soldiers began descending on bicycles—officers, couriers, and supply runners—making easy targets.

The thieves killed 14 men that afternoon, never firing more than one shot per target and never revealing their positions.

The Japanese response was predictable; they sent a patrol to find the snipers, with 40 soldiers moving uphill toward the thief positions.

Tachsky pulled his men back before contact, melting into the jungle.

The Japanese patrol found nothing but empty firing positions and dead bodies.

That night, Tachsky received new orders.

Division intelligence had located a Japanese ammunition depot near Garapan, Saipan’s capital city.

Command wanted the thieves to scout the depot, report on security, and possibly destroy it if the opportunity arose.

The mission was akin to a suicide run—Garapan sat two miles behind Japanese lines, with thousands of enemy soldiers between Marine positions and the city.

There would be no support and no backup; if something went wrong, the thieves would be on their own.

Tachsky selected eight men—the best fighters in the platoon—and informed them they would leave at 0200 on June 17th to scout the depot and return before dawn.

He did not disclose the intelligence report he had read that afternoon, which stated that Japanese commanders had ordered their troops to take no prisoners—wounded Marines were being used as bait to ambush rescue parties, and the enemy was preparing for a final banzai charge that would throw every available soldier at Marine lines.

The thieves were walking into hell, and they would not return as the same men who left.

The eight-man patrol departed Marine lines at 0200 on June 17th, moving through the darkness without moonlight.

They traveled west through sugarcane fields toward Garapan, stopping every 50 yards to listen.

The jungle was never silent on Saipan; Japanese patrols moved constantly, and artillery rumbled in the distance.

Wounded men screamed in no man’s land between the lines.

By 03:30, the thieves had covered a mile, crossing two Japanese patrol routes without being detected.

Sergeant Bill Canple led the way, reading terrain by feel and stopping whenever he sensed movement ahead.

The rest of the patrol followed in single file, maintaining 10-foot intervals and communicating only through hand signals.

They reached the outskirts of Garapan at 0415.

The city had been flattened by naval bombardment, with buildings reduced to rubble and streets cratered.

Yet, the infrastructure remained intact.

The thieves could see Japanese soldiers moving through the ruins, supply trucks, and communication lines.

This was still a functioning military base despite the destruction.

The ammunition depot sat on the northern edge of town, surrounded by three concrete bunkers and barbed wire.

Guards were stationed at each entrance, and Tachsky counted 16 visible soldiers, likely more inside.

His orders were to scout and report, not engage, but he saw an opportunity.

The bunkers had ventilation shafts—narrow openings in the concrete large enough for a satchel charge.

If they could place explosives without being detected, they could destroy the entire depot and eliminate tons of Japanese ammunition, crippling enemy artillery for days.

He made the decision: two men would approach the nearest bunker and plant charges while the rest provided covering fire if things went awry.

Corporal Rosco Mullins and Private Otto Heeble volunteered, both having engineering experience and understanding demolitions.

They moved toward the bunker at 0430, crawling the last 100 yards and taking 20 minutes to reach the ventilation shaft.

Japanese guards walked patrol routes just 30 feet away.

Mullins waited until a guard turned his back, then lifted the satchel charge to the ventilation opening, wedged it inside, set the timer for 15 minutes, and pulled back slowly.

They were just 10 yards from the bunker when a guard spotted them.

The Japanese soldier shouted and raised his rifle.

Mullins fired first.

The guard dropped, but his shout alerted the entire depot.

Whistles echoed through the ruins as soldiers poured out of buildings.

The thieves opened fire from their position 200 yards away, covering Mullins and Heeble while they ran.

The satchel charge detonated at 0457—three minutes early.

The explosion tore through the bunker, followed by secondary explosions as ammunition inside ignited.

Artillery shells, mortar rounds, small arms ammunition—everything ignited in a chain reaction.

The sky turned orange, and debris rained down across Garapan.

The thieves used the chaos to escape, running east through sugarcane fields while Japanese forces tried to contain the fires and evacuate remaining ammunition.

By 0600, they had crossed back into Marine lines—all eight men, with no casualties.

They had destroyed the largest ammunition depot in northern Saipan.

Division Intelligence estimated the explosion eliminated 30% of Japanese artillery ammunition.

Enemy fire dropped significantly over the next two days, leading to decreased Marine casualties and accelerated advances.

However, the mission had consequences.

Japanese commanders realized that Marine scout units were operating behind their lines.

They increased patrols, set ambushes, and began using wounded Marines as bait.

Any Marine caught alone faced immediate execution.

The rules of warfare on Saipan changed after Garapan.

On June 19th, a thief patrol walked into an ambush near Mount Tipo Pale.

Four men were scouting a trail network when Japanese soldiers positioned themselves in trees and underground positions.

They waited until the patrol was surrounded before opening fire.

The patrol leader was killed instantly, and the other three fought their way out, wounded.

One man took a bullet through the shoulder, while another sustained shrapnel in his leg.

They made it back to Marine lines but brought terrible news.

The Japanese had used two wounded Marines as bait, leaving them crying for help in an open clearing.

When the thief patrol approached, the ambush was triggered, resulting in the deaths of the wounded Marines in the crossfire.

That night, the 40 thieves held an unofficial meeting—no officers present, just enlisted men.

They voted unanimously: no thief would be taken alive.

If wounded and unable to escape, other thieves would ensure a quick death rather than capture and torture.

The war on Saipan had become personal.

By June 23rd, the 40 thieves had been in continuous combat for eight days—no rest, no rotation off the line.

They operated in 12-hour shifts, with half the platoon scouting during the day and the other half infiltrating Japanese positions at night.

Sleep came in two-hour intervals, and food was whatever they could steal or scavenge.

Casualties mounted.

The platoon had started with 40 men, but by June 23rd, only 32 remained combat effective.

Three were dead, and five were wounded badly enough for evacuation.

The mathematics were simple: if combat continued at this rate, the platoon would cease to exist by July 1st.

But they kept hunting.

On June 24th, a four-man team scouted Japanese positions in the Kagman Peninsula and discovered a battalion command post in a cave system.

They found 20 officers, radio equipment, and maps showing defensive positions across northern Saipan.

The team could not assault the cave due to too many guards, so they marked the position and called in artillery.

Naval gunfire destroyed the cave at 1600 hours with a direct hit from 14-inch shells.

The entire command structure of a Japanese battalion disappeared in one strike, causing enemy coordination to collapse.

Marines advanced 300 yards that afternoon with minimal resistance.

The next day brought the worst loss the thieves would suffer.

Corporal Martin Dyer led a patrol into dense jungle near Mount Tapochow with five men, tasked with scouting Japanese artillery positions reported in the area.

They found the artillery—four Type 92 guns positioned in a narrow ravine, camouflaged with vegetation and completely hidden from aerial reconnaissance.

Dyer’s patrol observed the position for 30 minutes, counting crew members and noting ammunition storage locations before beginning their withdrawal.

They were just 200 yards from the artillery position when Japanese infantry appeared from three directions.

The ambush was perfect.

Machine guns opened fire from elevated positions while rifles shot from ground level.

The patrol was caught in the kill zone with no cover.

Dyer ordered his men to scatter and run for Marine lines.

He stayed behind with a Browning automatic rifle, providing covering fire while his team escaped.

Three men made it out, but Dyer and one other Marine did not.

The Marine who stayed with Dyer was later found dead from multiple gunshot wounds.

Dyer’s body was never recovered; Japanese forces had overrun the position before Marines could retrieve the remains.

The patrol survivors reported that Dyer had killed at least seven Japanese soldiers before his position was overwhelmed.

For his actions, he was posthumously awarded the Navy Cross.

The citation noted that he sacrificed himself to ensure his patrol’s survival, and his leadership and courage were in keeping with the highest traditions of the Marine Corps.

The thieves took Dyer’s death hard—he had been a popular and good leader, the kind of Marine who never asked anyone to do something he would not do himself.

His loss reminded everyone that skill and training only delayed the inevitable on Saipan.

Eventually, the numbers caught up.

On June 26th, news changed the tactical situation.

Japanese forces were preparing for a massive banzai charge.

Intelligence estimated 3,000 soldiers would attack Marine positions in a suicidal assault.

Command wanted the thieves to infiltrate Japanese assembly areas, locate officers, and eliminate them before the attack began.

Tachsky received orders at 2200 on June 26th, stating that the banzai charge would likely happen within 48 hours.

He had one night to disrupt Japanese preparations.

His mission was to take 20 thieves deep behind enemy lines, find command posts, kill as many officers as possible, and create chaos before the assault.

It was the most dangerous mission the platoon had received.

Japanese forces were consolidating, with thousands of soldiers moving into attack positions.

Security would be intense, and the thieves would be operating in an area saturated with enemy troops.

Extraction would be nearly impossible if things went wrong.

Tachsky briefed his men at 2300, outlining the odds, warning them that casualties would be high, and asking for volunteers.

All 20 men stepped forward—not because they were brave, but because they understood what would happen if they failed.

The banzai charge would hit Marine lines with overwhelming force; thousands of men would die unless someone disrupted Japanese preparations first.

The thieves would go.

They would hunt officers in the darkness, and they would probably not all return.

The 20 thieves moved out at midnight on June 27th, under a heavy cloud cover with no moon—perfect conditions for infiltration.

They split into five teams of four men each, with each team assigned a designated sector.

Each team knew they were on their own if contact occurred.

Tachsky led the center team, moving west through Japanese lines toward reported command post locations.

By 0200, they had penetrated a mile into enemy territory, finding Japanese soldiers everywhere—sleeping in foxholes, standing guard, moving supplies.

Thousands of men were preparing for the assault.

The first officer died at 0230—a Japanese captain studying maps by lamplight inside a captured American tent.

Tachsky’s team approached within 50 yards and fired a single shot from a suppressed Springfield.

The captain dropped forward onto his maps, and the guards did not even hear the shot.

Over the next three hours, the five thief teams eliminated 17 Japanese officers—majors, captains, and lieutenants, all part of the command structure for the banzai charge.

Each kill was silent, and each team extracted without detection.

By 0530, all 20 thieves had returned to Marine lines—zero casualties.

The banzai charge commenced at 0400 on July 7th, with 3,000 Japanese soldiers screaming and charging with fixed bayonets.

They hit Marine positions along a two-mile front in a ferocious assault.

Hand-to-hand combat erupted as Marines fought with rifles, pistols, knives, entrenching tools—anything that could kill.

However, the Japanese attack lacked coordination.

Officers who should have directed the assault were dead, and units attacked without support.

Communication broke down, and what should have been an organized offensive devolved into a chaotic charge.

Marines held their positions, and artillery and machine gun fire cut down wave after wave of Japanese soldiers.

By 0800, the banzai charge had failed.

The Japanese lost 2,500 men, and the Marine line held.

The battle for Saipan effectively ended that morning, and organized Japanese resistance collapsed.

Remaining enemy forces retreated to caves and prepared for final stands.

The 40 thieves had done their job; their nighttime raids disrupted Japanese command, making the difference between a coordinated assault that might have broken through and a suicidal charge that accomplished nothing.

The platoon finished the Saipan campaign with 27 men, suffering 13 casualties over 21 days of combat—four dead and nine wounded.

The survivors returned to Hawaii in August, but the platoon was disbanded in October.

Men were distributed to regular infantry units as the Marine Corps decided specialized scout sniper platoons were too costly in terms of casualties, but their legacy lived on.

Frank Tachsky received the Silver Star for his leadership and effectiveness.

His methods influenced Marine reconnaissance doctrine for the remainder of the war.

The concept of small teams operating independently behind enemy lines became standard practice.

What William Whailing created on Guadalcanal, the 40 thieves perfected on Saipan.

Modern Marine scout snipers trace their lineage directly to these men.

Whailing’s training methods, Tachsky’s selection criteria, the fieldcraft, the silent killing, the independence—all of it became foundational in Marine sniper operations.

The scout sniper military occupational specialty was retired in December 2023 after 81 years, but the legacy remains in reconnaissance platoons, tactics manuals, and stories passed down through generations of Marines.

They learned that sometimes the deadliest warriors are the ones who remain invisible.
