At 8:44 a.m. on June 15th, 1944, First Lieutenant Frank Tachsky crouched in a Higgins boat 300 yards off Saipan and thought, This is either the smartest thing the Marine Corps ever did… or the dumbest.

The coxswain gunned the throttle. The boat slammed down off another wave. Salt water and diesel fumes mixed into a sour fog that stung the eyes. Japanese artillery shells were already walking toward them through the surf, each geyser of white water taller than a telephone pole.

Forty men hunkered behind him.

Forty men the Marine Corps had called troublemakers, thieves, brawlers—criminals, some of them.

Forty men Frank had handpicked.

He turned his head just enough to see them in the gloom under the boat’s gunwales. Helmets low. Faces streaked with sweat and grime and the white of seasickness. Every one of them carried more knives and grenades than regulation allowed. Every one of them had, at some point, been told by some captain or sergeant major that they’d never amount to anything in the Corps.

Every one of them had volunteered for this.

Well. “Volunteer” was a strong word.

The Marine Corps had given them a choice: the brig… or combat duty in a brand-new scout sniper platoon.

They’d chosen combat.

A shell exploded close off the port bow, showering the boat with fragments and foam. Someone behind him cursed. Someone else laughed—sharp, high, a little too loud.

“Hold your fire!” Frank barked over the engine and shell bursts, more out of training than necessity. They didn’t have anything to fire yet. Their rifles were still slung, bolts taped shut to keep sand out.

He checked his watch. 8:44.

Three minutes until H-hour for this wave.

Three minutes until they stopped being an experiment.

Six months earlier, there had been no “40 Thieves.”

There was just Camp Tarowa in Hawaii—dry coral dust, blistering sun, and a colonel with eyes that had seen too much blood on Tarawa and were determined not to see it again if he could help it.

Colonel James “Jim” Rizley of the 6th Marines had watched nearly a thousand Marines die on Betio in 76 hours. Men cut down on beaches because no one knew exactly where the Japanese machine guns were until it was too late. Men blown apart by mortars from positions no aerial photograph had ever quite captured.

So when the regiment came back and refit, he sent a request up the chain that was half insanity and half pure clarity.

He wanted a special platoon.

Not more riflemen. Not more mortar crews.

He wanted 40 men who could move alone behind enemy lines, kill silently, map fortifications, and vanish before anyone knew they’d been there.

He wanted—though the words didn’t exist yet—a special operations unit.

The Corps didn’t really know what to do with that request. The Army had Rangers. The Brits had their commandos and their sneaky outfits who rowed ashore in rubber boats and blew up things and rowed back out.

The Marine Corps had rifle companies and tanks and a reputation for impossible frontal assaults.

It also had brigs.

That’s where Frank came in.

He was 29, from New Brighton, Pennsylvania, and still had a slight steel-town edge to his vowels. Combat wise he was no rookie—Guadalcanal, Tarawa, then a stint training replacements at Camp Tarowa. He’d seen good men die because someone up the chain didn’t know what was over the next ridge.

When Colonel Rizley called him into the regimental command post and laid out the idea, Frank listened without interrupting. That alone made him unusual in the 6th Marines.

“I need a platoon that doesn’t think like Marines,” Rizley said finally. “I need men who cheat. Men who… improvise. Who won’t freeze the first time they’re on their own.”

“And where exactly do you find men like that, sir?” Frank asked.

Rizley smiled a tired, humorless smile.

“You go to the brig,” he said.

It turned out disproportionate numbers of the kind of men he needed were in punishment details.

Frank developed a recruiting rule, simple enough to brief a guard with:

When two Marines got into a fight, the winner went to the brig. The loser went to the infirmary.

Frank wanted the winners.

The men who’d already proven they could handle themselves in close, ugly combat. The ones with broken knuckles and uneven noses and a glint in their eyes that said they’d rather solve problems with their fists than with paperwork.

Over two months at Camp Tarowa, he assembled 42 Marines from brig rosters and punishment details across Second Marine Division.

The youngest was seventeen, having lied about his age when he enlisted.

The oldest was thirty-four, with enough scars and tattoos to qualify as living topography.

Most had civilian criminal records—petty theft, assault, bar fights. One had been a professional boxer. Another had worked as a bodyguard for a Chicago gangster and had a bullet scar just above his left kidney to prove it.

The Corps had written them off as problems.

Frank looked at them lined up on the dusty parade ground for the first time. Bent cigarettes behind ears. Uniforms “customized.” One guy’s sleeves rolled higher than regs allowed to show off his tattoos.

He saw not problems.

He saw potential.

“The Marine Corps calls you troublemakers,” he told them, pacing slowly in front of the formation. “You don’t follow rules. You get in fights. You steal things that aren’t nailed down. You hate being told what to do.”

A few of them smirked outright. A couple just stared back, flat-eyed.

“Good,” Frank said. “That’s exactly why you’re here.”

He let that hang for a heartbeat.

“I don’t need parade-ground Marines. I need survivors. Men who can go ten miles behind enemy lines, kill sentries with their hands, call in artillery on positions nobody else has seen, and then get back home alive. Men who can see a line they’re not supposed to cross and say, ‘The hell with that line.’”

He stopped and looked down the row at a broad-shouldered lance corporal with a boxer’s flat nose. “You like rules, Lance Corporal?”

The man shrugged. “Depends who’s making ’em, sir.”

“From now on, I make them,” Frank said. “And there are only three you need to remember.”

He held up a finger.

“One: You don’t quit on me. I don’t care if you’re puking your guts out or your feet are bleeding. If you can move, you move.”

Second finger.

“Two: You don’t quit on the man to your left or your right. I catch one of you leaving another behind, I’ll personally throw you back into the brig and let the MPs have you.”

Third finger.

“Three: If we do this right, the men on the next beach we land on will have a better chance than the men at Tarawa. We’re not here for glory. We’re here to make sure fewer Marines die because some Japanese officer hid a machine gun where we didn’t expect it.”

He let his hand drop.

“That’s it. You follow those three rules, I don’t care if you came here straight from Leavenworth. You’re mine now. Welcome to the Scout Sniper Platoon, Sixth Marines.”

Someone in the ranks muttered, “Scout sniper, hell. We’re just a bunch of thieves.”

It rippled down the line.

“Forty thieves,” someone else said.

The name stuck like chewing gum on a boot heel.

They carried it with them the rest of the war.

Training at Camp Tarowa made regular Marine boot camp look like summer camp.

They learned things the manual never mentioned.

How to kill quietly, using knives, garrotes, or bare hands. How to approach a sentry from behind on soft feet, avoiding twigs and loose coral, then break his neck in one clean motion.

They learned how to move through jungle without disturbing the vegetation enough to give away their path. How to read Japanese maps and field orders. How to call in naval gunfire and artillery properly—grid references, adjustments, corrections.

They became intimately familiar with the M1903 Springfield rifle, fitted with 8-power Unertl scopes. They learned how to lie motionless for an hour, sight picture steady, until the moment the crosshairs settled on a man-sized target at 600 yards… and then let the breath out, squeeze, and watch the target fall.

They practiced with bazookas, two-man teams loading and firing until their shoulders ached from the backblast. Tanks, pillboxes, fortified caves—targets they would be expected to crack open when they found them.

They studied Japanese tactics. How the enemy defended islands. Where they placed machine guns in relation to likely avenues of approach. How their officers thought about banzai charges and last-ditch stands.

And they stole.

Lord, how they stole.

The Marine Corps was the poorest-equipped branch in 1944. The Army got the good stuff first. The Navy took what they wanted. The Marines got what was left, and often not enough of even that.

If you wanted something decent, you pulled “midnight requisition.”

Frank’s men turned thievery into an art.

They raided Army supply depots for better rations and ammo. They slipped into Navy warehouses and walked out with canvas, rope, and extra radios. Once, two of them “liberated” a jeep by convincing a drunken Army lieutenant that they’d been sent to take it to the motor pool.

The rest of the regiment watched them with a mixture of resentment and admiration.

“Forty Thieves,” a corporal from another company said once, shaking his head as he watched Frank’s men carry away their haul. “They’re gonna end up in Leavenworth when this is over.”

“Not if the Japs get them first,” his buddy replied.

Frank heard and tucked the line away.

He was a practical man. He wasn’t under any illusions about the math.

The casualty estimates for scout sniper units in the Pacific ran around 73%.

Three out of four.

He looked at his forty men—the kid who’d lied about his age, the Chicago bodyguard with the gangster’s bullet scar, the quiet kid from Kansas who never talked about what landed him in the brig—and tried to imagine three of them dead for every one still standing.

He failed.

So he focused on the training.

If the statistics said 73% died, his job was to tilt the odds.

By June 1944, they were ready.

At least, as ready as anyone ever is for an island full of people trying to kill them.

Their orders were clear:

Land with the first wave.

Push inland ahead of the main force.

Locate Japanese machine guns, mortars, artillery, tanks.

Radio back coordinates for naval gunfire and artillery.

Disappear again.

Do it for days at a time.

No support if things went bad. No organized rescue. If they were captured, the intelligence briefings made clear what would happen. The Imperial Japanese Army did not extend mercy to prisoners. American POWs on Pacific islands tended to die slowly.

Saipan, they’d been told, wasn’t some far-flung outpost.

It was part of Japan itself.

Thirty thousand Japanese Army and Navy troops on an island 14 miles long and five miles wide. Thousands of armed civilians. Mount Tapochau rising 1,500 feet in the center, giving the enemy observation posts over every beach.

The Japanese had concrete pillboxes, interlocking trenches, underground tunnels. Every likely landing zone registered for artillery and mortars.

Marine planners expected over 50% casualties for the invasion force.

In the Higgins boat now, with the shells getting closer and the beach looming ahead, that number felt uncomfortably real.

Frank glanced back one last time before the ramp dropped.

He saw Strombo—the lanky Montana kid with a talent for bazookas—jamming gum between his teeth.

He saw Mullins, a compact corporal from Tennessee, eyes half-lidded like it was just another long day on the range.

He saw Hajes, quiet, steady, hands resting loosely on the tube of his bazooka like it was part of his body.

“Listen up!” Frank shouted over the thunder.

Forty sets of eyes turned forward.

“You already did the hard part,” he said. “You stayed in this platoon. You did the training. You didn’t wash out. That means you’re tougher than you were six months ago. Tougher than most men on those ships behind us.”

He jerked his head toward the invisible line of transports offshore.

“Nobody expects us to come back with all forty. The odds say most of you won’t. But odds don’t know about the forty thieves, do they?”

Someone snorted. Somebody else said, “To hell with the odds.”

“We’re going in ahead of everybody else,” Frank went on. “We find the stuff that’ll kill Marines and we break it. We mark it. We burn it. We make damn sure that when the regular grunts walk up these beaches, they don’t die the way they did at Tarawa. You do your job, and some kid from Iowa or Harlem or South Boston walks out of this alive because of you. That’s the deal.”

The coxswain shouted, “Thirty seconds!”

Frank nodded once.

“Rule One,” he yelled. “You don’t quit on me. Rule Two: You don’t quit on each other. Rule Three?”

“Fewer dead Marines!” somebody shouted.

“Damn right,” Frank said. “Lock and load.”

The first machine-gun rounds skipped across the water ahead of them like someone flicking stones.

The ramp slammed down into chest-deep water.

The forty thieves splashed forward into hell.

They reached the beach at 8:47 a.m.

Men were dying all around them—Army, Marines, Navy beach parties. Mortar bursts chewed up the sand. Somebody’s leg flew past Frank and landed in the surf, the boot still on.

He didn’t let his men stop.

“Off the beach!” he bellowed. “Move! Move! Move!”

Their mission wasn’t to take the sand. Other men would take it and hold it and die on it. His job was to get past it before it pulled him under.

They pushed inland, rifles up, eyes scanning.

By 9:30, they were 300 yards in—farther than any other Marine unit on that sector.

Ahead of them wasn’t a nice, open battlefield.

It was jungle.

Thick, tangled, blind.

Somewhere in that green mass, 30,000 Japanese soldiers waited.

Night would fall in nine hours.

That was when their real work would begin.

The 40 Thieves moved in a loose lattice, each man roughly 50 yards from the next and always within visual range of someone else.

They used hand signals Frank had drilled into them—stop, scatter, rally, eyes left, eyes right, target.

Standard Marine doctrine said stay tight, stay on the radio, stay under control.

Frank’s orders were different.

“Once we’re off that beach,” he’d told them, “you are your own chain of command. You see something we need to know, you mark it. You call it in. You don’t wait for some major in a tent to give you permission. We don’t have time.”

At 10:15, Sergeant Bill Canuple lifted a hand and dropped to a knee.

He’d seen something in a ridge to their front.

Frank belly-crawled up beside him and looked.

Concrete.

A pillbox.

Half-buried in the slope, face toward the valley where—according to the operations map—the main line of the Second Marine Division would be pushing that afternoon.

It was beautiful, in the ugly way of all well-built kill zones.

Interlocking fields of fire covering all three possible avenues of approach.

Camouflage so tight you’d never see it from the beach.

Inside, through a narrow firing slit, Frank could just make out the barrel of a heavy machine gun.

Type 92, probably.

Seven-man crew.

He pictured Marines walking into that valley in a few hours, shoulders heavy with packs, thinking the worst was behind them.

He pictured them being mowed down from this slit like wheat.

He checked his map.

Three likely routes.

The machine gun covered every one.

He had a choice: report the pillbox, hope artillery or naval gunfire found it in time…

Or kill it now and risk blowing his platoon’s cover.

He took 30 seconds to decide.

“Strombo,” he whispered.

The bazooka man slid up beside him.

“Range?” Frank asked.

Strombo squinted, thumb rubbing the launcher’s tube.

“Eighty yards,” he said. “Maybe eighty-five.”

“You hit that slit?”

“Yessir.”

“First shot.”

Strombo’s eyes flicked sideways. “First shot, sir.”

Frank nodded once.

“Do it.”

Strombo set up in a shallow depression, loader at his side.

The rest of the platoon spread into a loose security perimeter, watching for any stray Japanese eyes.

At 10:32 a.m., Strombo squeezed the trigger.

The rocket roared out, leaving a backblast that scorched the grass behind him.

It hit the pillbox square in the firing slit and detonated inside.

The explosion blew the back wall out in a spray of stone and sandbags. The pillbox shuddered and went still.

The seven men inside never knew what hit them.

Before the smoke cleared, the forty thieves were already 300 yards deeper into the jungle.

When Second Marine Division units moved up that valley four hours later, no one shot at them from that ridge.

By noon, the thieves had identified seventeen Japanese positions.

Eight machine-gun nests. Four mortar pits. Three artillery observation posts. Two ammunition dumps.

They marked each coordinate carefully and passed it back to regimental headquarters over the radio using code they’d been drilled on until it invaded their dreams.

Twenty minutes later, five-inch shells from destroyers offshore began walking across the map grids Frank had transmitted, each impact right where the thieves had seen guns and ammunition.

From their concealed perches, they watched as concrete cracked, dugouts collapsed, and ammunition dumps turned into fountains of fire.

This was the mission in its purest form.

Find.

Mark.

Destroy.

Disappear.

They pushed deeper.

Their advance carried them nearly two miles inland by early afternoon, far beyond any other American unit.

They moved through terrain the Marines wouldn’t reach for three more days.

Every hundred yards revealed something new—a dug-in platoon here, an artillery observation post there, a trench line carefully sited to catch anyone who tried to flank the beach.

Saipan was more heavily fortified than the intelligence staff had dared put on paper.

In one small valley alone, Frank counted over 200 enemy soldiers, dug into positions that would have taken days of frontal assault and cost hundreds of lives.

With coordinates, though, the whole valley could be turned into a cratered moonscape in minutes.

The forty thieves were, quietly and systematically, changing how the Marine Corps fought.

At 3:40 p.m., they found the thing that would test that change like nothing else.

It was Corporal Mullins who spotted the first tank.

They’d been moving along a low ridge north of Charan Kanoa when the smell hit them—oil, fuel, hot metal. Different than the usual jungle rot and cordite.

Mullins lifted his binoculars and peered down into a grove of trees.

“Sir,” he whispered. “You’re gonna want to see this.”

Frank crawled up, glassed the grove.

Under camouflage netting, like a herd of steel animals at rest, sat Japanese Type 97 medium tanks.

Not one. Not a dozen.

Thirty-seven of them.

He counted twice to be sure.

Tank battalion staging area.

Marine intel had said maybe twelve tanks total on Saipan.

Here was three times that in one place.

Frank felt his stomach go tight.

Tanks were bad news everywhere, but on islands with thin front lines and narrow beaches, they were worse. Japanese doctrine called for massed night tank attacks—slamming into American lines at full throttle when artillery and naval gunfire were least effective.

If these 37 tanks hit the beach after dark, with the lines still shaky and supply dumps exposed…

He didn’t want to finish the thought.

He radioed back the coordinates.

The reply from headquarters came back eight minutes later, terse.

ALL AVAILABLE NAVAL GUNFIRE ENGAGED IN SUPPORT OF FRONTLINE TROOPS. AIR STRIKES COMMITTED. ARTILLERY NOT YET IN POSITION. NO IMMEDIATE FIRES AVAILABLE ON TARGET. CONTINUE OBSERVATION. OUT.

No one was coming to kill these tanks for him.

Not for hours—and hours they didn’t have.

Frank looked at the tanks, at the crews lounging in the shade, at the infantry milling around.

He did the math.

Six bazookas in the platoon.

Six rounds per bazooka.

Thirty-six rockets.

Thirty-seven tanks.

Perfect math for a suicide note.

Doctrine said a forty-man unit did not, under any circumstances, attack a full tank battalion.

But doctrine had not written this platoon.

He stared down into that grove, thought of what would happen if those tanks hit the gap in the lines after dark, saw in his mind’s eye the beachhead ripped apart, supply dumps burning, wounded men being overrun in their foxholes.

He made a decision.

“Bazooka teams,” he said. “On me.”

They slid into position in a wide semicircle around the tank park, each team forty yards apart. Shooters and loaders. The plan was simple: hit as many tanks as possible in the first thirty seconds, then melt back into the jungle before the Japanese got organized.

They didn’t need to kill all thirty-seven. Kill or cripple ten or fifteen, and maybe the attack would be blunted enough for the grunts at the beach to stand.

At 4:25 p.m., as the teams were settling into firing positions, something changed.

Engines coughed.

One, then another, then all of them.

Thirty-seven Japanese tank engines rumbled to life.

Crews scrambled up onto hulls, officers shouted orders. Infantry formed up around the vehicles.

This wasn’t a repositioning shift.

This was a pre-assault warm-up.

Frank checked his watch.

4:28 p.m.

Sunset was at 7:12.

They were starting earlier than expected, aiming for dusk.

The battalion was now fully alert and moving.

Whatever chance they’d had for a surprise bazooka ambush evaporated in the diesel fumes.

He ground his teeth, then keyed his radio.

“Shadow them,” he told his scattered teams. “No shots unless there’s no other choice. We’re eyes now, not teeth.”

Headquarters, when he reported, sent back confirmation.

MAINTAIN OBSERVATION. DO NOT ENGAGE. CONTINUE REPORTING.

So they followed.

Two hundred yards off the flank, using jungle cover, pacing the iron column like wolves dogging a herd.

Every ten minutes, Frank sent updated positions.

Behind them, on the beaches, Marines shifted.

Bazookas were handed out to frontline platoons. Sherman tanks from the 2nd Marine Tank Battalion rumbled toward likely choke points. Artillery batteries, finally ashore, adjusted their aim.

The entire second Marine Division braced for a tank attack it would never have seen coming without these forty men in the jungle.

At 6:15 p.m., about a mile from the beach, the Japanese column halted.

Officers gathered in a little knot. They pointed at maps, gestured toward the coast, argued.

Frank watched through his glasses, feeling time slip by like sand.

Eleven minutes later, the conference broke up.

The tanks turned.

Not straight toward the main beaches where the Marines expected them.

North.

Frank frowned.

North was jungle. Rough terrain. On the Marine maps, no significant targets.

The tanks drove another mile that way, then swung west again.

By 7:05 p.m., as the sun bled down into the sea, the picture clicked into place in Frank’s mind.

They weren’t going to hit the main beachheads.

They were going for the seam.

The gap between Second Marine Division and Fourth Marine Division—thinly held, awkward terrain, artillery coverage shaky, no one quite sure whose responsibility it was.

Break there, and they’d split the American line in half.

He radioed the warning in plain, urgent language.

But dusk is a weird, dangerous time on a battlefield.

Radios switched frequencies. Units shifted positions. Artillery resupplied. Tankers refueled.

By the time the warning reached the right people, the tanks were already at their start lines.

The gap was held by two understrength Marine companies—about 340 men.

Against 37 tanks and roughly a thousand Japanese infantry.

At 7:23 p.m., the Japanese attack began.

From a rise in the jungle, the forty thieves watched it unfold.

Marine bazooka teams knocked out three tanks in the first exchange. Shermans brewed up a couple more.

But 34 tanks and hundreds of screaming infantry kept coming.

Within minutes, the Marines were falling back, lines bending and fraying.

If the tanks reached the beach, they could kill command posts, destroy radios, blow apart the fragile coordination holding the whole invasion together.

Frank scanned the battlefield, trying to figure where his tiny unit of heavily armed ghosts could do the most good.

Then he saw it.

One Type 97 had broken off from the main attack.

It was angling down a shallow ravine, away from the worst of the fighting.

Toward the Sixth Marines’ command post.

Toward Colonel Rizley.

The ravine was a natural notch in the terrain that snaked straight down toward the tent city where radios crackled and maps were marked and the fragile improvisation of battle was being held together by a dozen overloaded staff officers and one very tired colonel.

Anti-tank guns couldn’t cover the ravine. The jungle was too thick on the flanks to get a good line of fire.

That tank commander had found a seam in the seams.

At 15 miles per hour, he’d be on top of the command post in three minutes.

Three minutes to kill the colonel and his staff, shred the radios, blast apart the nerve center of the divisional response.

Three minutes before the whole thing started running on rumor and guesswork.

The battalion’s focus was on the main assault. No one down there had seen this one tank.

Up on the ridge, one man had.

Frank grabbed the sleeve of the nearest bazooka man.

Herbert Hajes.

Quiet farm kid. Best shot in the platoon. Six hits out of six in training at Camp Tarowa.

Training targets didn’t move or shoot back.

Tanks sure as hell did.

“Come on,” Frank said. “You’re up.”

They ran.

Down the slope, slipping on loose soil, dodging roots, skidding around bushes. Hajes carried the bazooka like it weighed nothing. Another Marine pounded behind them with a tube of rockets.

They cut across the ravine’s projected path, lungs burning.

At 7:31 p.m., they slid into position about thirty yards from where the ravine flattened out before the command post clearing.

Hajes dropped prone, propped the launcher on a rock, and aimed at the empty ground.

“Wait for it,” Frank said, kneeling beside him, chest hitching as he tried to slow his breathing.

Diesel growl rose, closer and closer.

Then the tank emerged from the ravine, a squat steel beast against the darkening sky.

Turret rotating.

Commander half out of the hatch, binoculars up, looking for enemy silhouettes.

Hajes tracked him, then let the sight swing down to the tank’s left side, just below the turret ring, where the armor was thinner.

The Type 97’s nose was coming almost straight at the command post. A frontal shot could bounce.

He needed the side.

The tank kept rolling.

Twenty-five yards.

Twenty.

Fifteen.

Then it stopped.

The driver idled the engine. The commander ducked inside briefly, then popped back up, map in hand.

He was checking his position.

Hajes exhaled.

He squeezed the trigger.

The rocket streaked across the short distance in a blur of flame and smoke and hit exactly where he’d aimed—left side, just under the turret ring.

The shaped charge punched through the armor like paper and detonated inside.

The tank bloomed fire.

All four crew died instantly.

Six seconds later, the ammunition cooked off and the entire vehicle erupted in a ball of orange and black that lit the jungle like a movie set.

Nearby Japanese infantry, seeing the sudden glare, interpreted it their own way.

They thought they’d stumbled onto a major Marine position.

They veered away from the command post and toward the blaze, toward what they assumed was a heavy line of bazookas and guns.

In reality, it was one bazooka, one exhausted shooter, and one lieutenant.

The effect was the same.

The command post lived.

Colonel Rizley kept yelling into radios, moving arrows on maps, keeping the response coordinated.

That one bazooka shot did more than just kill a tank.

It misdirected an entire Japanese infantry battalion at the exact moment they could have torn the heart out of the Marine defense.

Frank had just enough time to open his mouth to order Hajes to move when reality caught up.

The muzzle flash, the rocket’s smoke trail, the sudden explosion—every Japanese soldier within 500 yards homed in on it.

Machine-gun bullets started chewing up the ground around them.

Mortar shells whumped in, exploding in the trees, spraying them with splinters.

The forty thieves were suddenly the most interesting thing in that part of the jungle.

Now they had to get out.

Withdrawal under fire through jungle in darkness is the kind of thing war-college diagrams never quite capture.

Doctrine said stay together. Maintain cohesion. Move as a unit.

Doctrine had never tried to get forty men out of a bamboo thicket while mortars walked closer and closer.

The platoon broke into four- and five-man teams, each with a compass, a rough sense of the lines, and prearranged rally points.

They melted into the jungle.

Japanese patrols swept past, flashlights and shouted commands cutting through the undergrowth.

Several times, Marines lay flat in the leaf litter, faces pressed into the earth, while boots squished past inches away.

At 8:05 p.m., Strombo’s team—Strombo and three others—lay in a tangle of vines as a seven-man Japanese patrol moved through.

One soldier stopped.

Turned his head.

Stared directly at the place Strombo lay.

The Marine held his breath. Sweat ran into his eyes. A fly crawled across his neck. His finger tightened on the trigger of his rifle.

Forty-three seconds.

That’s how long the Japanese soldier stood there, peering into the darkness.

Then he shrugged, muttered something, and moved on.

By 9:00 p.m., about half the 40 Thieves had filtered into the primary rally point—a small clearing 600 yards behind Marine lines.

Frank counted heads.

Twenty-three.

Seventeen missing.

Standard practice said wait up to two hours for stragglers at a rally point.

But this rally point was too close to Japanese lines. Patrols were thick. Hanging around for two hours here was less “wait and see” and more “please find us and shoot us.”

Frank made another hard call.

They would pull the 23 back to Marine lines now, then send rescue teams at first light.

They approached the lines carefully.

No one wanted to get shot by a nervous nineteen-year-old Marine who saw movement in the dark and panicked.

Frank gave the recognition signal they’d prearranged with the frontline units—three short whistles, two long.

A challenge came from the darkness. He gave the password.

At 9:41 p.m., the first chunk of the 40 Thieves crossed back into friendly territory.

Twenty-three out of forty.

Seventeen still out there in the black.

The Japanese tank attack ground on through the night.

By dawn, 27 out of 37 tanks were burning wrecks. Bazookas, Shermans, artillery—everyone had pulled their weight. The lines had held, but only just.

When the casualty reports came in—78 casualties in 2/6, nineteen in F/2—they were bad.

Not as bad as they might have been if 37 tanks had hit the seam without warning.

But numbers on a report didn’t yet account for the cost inside Frank’s gut.

His platoon had been on Saipan less than 48 hours.

They’d lost men.

He didn’t yet know how many.

At first light on June 16th, search teams of four men each moved back into the jungle from Marine lines.

Their orders were simple and brutal.

Find the missing.

If they’re alive, bring them home.

If they’re dead, bury them and mark the spot.

At 7:05 a.m., the first body turned up. Private Donald Evans—two rounds to the chest, dead before he hit the ground. Dog tags gone, likely snatched by a Japanese soldier for a souvenir.

They buried him quickly, rifle and helmet marking the makeshift grave.

At 8:20, another team found three more bodies.

These men hadn’t died in a firefight.

Their hands were tied behind their backs.

They’d been bayoneted.

Captured wounded, then executed.

The Imperial Army had little respect for surrender—even less for enemy soldiers who surrendered. But these three hadn’t chosen anything. They’d been taken and murdered.

The search teams reported the discovery back to Frank.

He felt something cold settle in his chest and stay there.

By 10:00 a.m., six of the missing were found alive. They’d gotten turned around in the night but had eventually made their way back into Marine lines.

Missing count dropped from seventeen to eleven.

At 11:15, a search team’s scratchy radio came alive.

They’d found five more.

Hiding in a cave system about a mile behind Japanese lines.

Alive, but trapped. Japanese patrols were thick overhead. The five Marines couldn’t move without getting spotted.

Frank ran the options in his head.

Call in artillery to create a diversion?

That would alert the Japanese that something important was in that area, leading to more patrols and making any future rescue attempt harder.

Wait for night?

The trapped Marines had already spent one night in that hole. One of them had malaria, fever spiking. Another had dysentery so bad he could barely stand.

They weren’t going to last another twelve hours in the dark.

That left the other option.

Take a team.

Go get them.

Right now.

At 11:47 a.m., Frank and a six-man rescue team slipped back into the jungle.

They reached the cave at 12:33 p.m.

The five trapped Marines were pale, hollow-eyed, thirsty. The air in the cave smelled of sweat and fear and rock.

They handed out water. A corpsman checked the malaria case—temperature 103, skin hot and dry. He needed a hospital, not a hole in a hill.

But hospitals were behind Marine lines, and Marine lines were a mile of Japanese-controlled territory away.

The text in the operations log would later say simply:

11 men began movement toward friendly lines at 1305 hours.

The reality was messier.

They’d barely gone 400 yards when they ran into a Japanese patrol—twenty men in search formation.

Hide, and hope the enemy walked past?

Or attack, and kill them before they could raise the alarm?

Hiding risked discovery in a bad position.

Ambushing guaranteed gunfire, but perhaps on their terms.

Frank chose ambush.

They set up an L-shaped kill zone—most of the Marines along the patrol’s path, a smaller element at right angle to catch anyone trying to run.

At 1:23 p.m., the Japanese walked into it.

Frank gave the signal.

Eleven Marines opened fire.

In seven seconds, it was over.

Twenty Japanese soldiers dead.

No survivors. No radio calls.

Silence fell, broken only by the ticking of cooling metal.

Then the shouting started.

Not from the dead patrol.

From others, farther out, who’d heard the shots.

The jungle woke up with enemy voices. Whistles. The sound of boots running, branches snapping.

Every Japanese unit nearby now knew something was wrong here.

The Marines ran.

They abandoned stealth and hauled the malaria case and the dysentery case between them, boots slipping on roots, lungs heaving.

By 1:29, they hit a ravine.

Forty feet deep, steep sides.

Going around would add fifteen minutes. Staying on top meant certain contact with the units converging on the gunfire.

They went down.

Half sliding, half climbing, dragging the sick men, they reached the bottom at 1:33.

Japanese soldiers appeared on the ridgeline sixty seconds later.

Fire rained down.

Bullets sparked off rocks.

A grenade landed near the group, bounced, exploded—shrapnel shredded one Marine’s leg, peppered another with fragments.

They fired back on the move, laying down enough to keep the Japanese honest but not enough to anchor themselves in place.

The ravine channeled them forward.

At 1:38, they hit the worst possible sight.

A rock wall.

Box canyon.

No exit.

The Japanese began working their way down the sides, firing as they came.

It was about as pure a tactical nightmare as you could get. Eleven Marines. Two sick. Two wounded. 200 rounds of ammunition, give or take.

At least forty enemy soldiers and more showing up every minute.

Artillery support was impossible—they were too close to enemy positions. Air support would have killed them as surely as it killed the Japanese.

The forty thieves were on their own.

That was when Frank’s eye caught something.

The back wall of the canyon wasn’t clean rock. Vegetation grew thick at the base. Vines. Moss. A wet smell.

Water seepage.

Cracks.

“Check that,” he barked to two Marines.

They sprinted over, shoved vines aside, felt along the stone.

“There’s a gap, sir!” one shouted. “Can squeeze through. It opens up on the other side.”

That was all he needed.

“Go!” Frank yelled. “Sick and wounded first!”

One at a time, they wormed into the crack, packs off, rifles slung, rock scraping shoulders and helmets.

Completely blind.

No idea where it went.

Behind them, Japanese soldiers dropped into the bowl of the canyon and shouted triumphantly to each other.

By the time they reached the back wall and realized their American prey had vanished into solid rock, the Marines were halfway up the fissure.

It climbed like a chimney, steep and narrow, spiraling through the ridge.

They emerged on the opposite side at 2:07 p.m., 400 yards from where they’d entered.

The Japanese, focused on the canyon, never looked up here.

The Marines moved fast.

Six hundred yards of jungle in eight minutes, recognition signal to Marine lines, then the blessed call of a friendly challenge.

By 2:23, all eleven were back inside the perimeter.

Both sick men were carried straight to aid stations.

By nightfall, after more stragglers trickled in on their own and other bodies were found, the math was what it was.

The 40 Thieves had lost at least six men killed in their first 48 hours on Saipan.

Three more were missing and would never be found.

Twenty-two percent casualties.

Under the 73% scout sniper average.

Over any number any normal unit would consider “acceptable.”

Frank didn’t think in percentages that night.

He thought in names.

Evans.

The three bayoneted Marines whose faces he’d seen before someone covered them.

The missing three whose stories would end in a line on a casualty list that read MIA and no more.

Colonel Rizley sent a message up the chain to the regimental staff.

40 Thieves accomplished mission. Casualties acceptable.

It was the language of war.

At 1800 hours, another message landed in Frank’s hands.

One night.

That’s what they’d get.

One night to rest, resupply, integrate replacements.

At dawn on June 17th, they’d go out again.

This time, deeper.

Saipan still held 29,000 Japanese troops.

The 40 Thieves now numbered thirty-seven.

At 0530 on June 17th, they slipped out of Marine lines in darkness.

Their objective was a ridge system three miles inland where Marine intel believed Japanese artillery hid in caves.

Those guns had been chewing on the beachhead for two days—shells dropping into supply dumps, killing weary stretcher bearers, smashing bulldozers trying to carve roads out of coral.

Aerial recon hadn’t found them. The Japanese had dug their guns into the bones of the island.

Only ground recon could pinpoint them.

Hand signals. No unnecessary radio chatter. No smoking, no talking, no metallic clinks.

First mile in 47 minutes.

No enemy contact.

Second mile slower—steeper slopes, denser jungle, rocks that tore at boots. Sweat soaked their cammies. Mosquitoes whined.

They reached the ridge around 0815.

From below, it had just looked like another hump of rock.

Up close, it was a fortress.

Cave mouths gaped like empty eyes along its flanks.

The thieves counted eight entrances big enough to roll artillery through.

Mullins and Strombo volunteered to go in.

Frank didn’t have to ask twice.

At 0940, the two men took flashlights whose beams were carefully muffled, extra canteens, and a sketch map.

They entered the nearest cave.

The air inside was twenty degrees cooler. Damp. The beam from Mullins’ light picked out walls stained with soot and sweat.

The tunnel ran 200 feet in before splitting and splitting again.

Voices echoed somewhere ahead—Japanese, laughing, talking, unhurried.

At 1012, the beam picked out a barrel.

Type 91 105mm howitzer.

Thirty feet from the cave mouth. Ammunition stacked in niches carved out of the rock.

No crew in sight—probably on a break somewhere deeper inside the complex.

They marked the gun’s location and moved on.

Two more guns in the next forty minutes.

A command post with maps pinned to the walls. An ammo magazine with roughly 2,000 rounds stacked in neat rows. Sleeping quarters for at least sixty soldiers—bunks, blankets, personal trinkets.

The tunnel network connected all eight entrances.

The Japanese could roll a gun forward, fire a few rounds, then pull it back and move it laterally inside the hill to a new exit before American counter-battery fire hit.

No wonder the Marines hadn’t been able to silence them.

At 1103, Mullins and Strombo froze and killed their lights.

Boots.

Shuffling.

Voices.

They flattened themselves into a narrow alcove as a dozen Japanese soldiers walked past, close enough that Mullins could see the fuzz on the back of one man’s neck in the weak reflected light.

The patrol passed without a glance in their direction.

They took that as their cue.

They were deep enough. They had more intel than anyone topside had ever dreamed of.

Time to leave.

They emerged into the sunlight at 1127.

Frank took one look at the map they’d sketched and whistled softly through his teeth.

“Artillery can’t do much,” he said. “Caves are too deep. We’re not blowing those guns with shells. We’re sealing them in.”

Marine engineers with explosives could do it—collapse entrances, trap men and guns behind tons of rock.

Those engineers were days away from this ridge.

For now, the thieves did what they could.

They mapped every entrance, every observation slit, every track line on the hill. They sent the coordinates back.

Then they moved on to their second target.

Garapan.

Saipan’s prewar administrative capital.

The question from the brass was simple: were the Japanese going to defend it as a fortress, or had they abandoned it?

The answer would dictate how much blood Marines would have to spend to take it.

The distance was four miles of enemy territory in broad daylight.

With anyone else, it would’ve been madness.

With the forty thieves, “madness” had become something like a job description.

They reached the outskirts around 1540.

Garapan had been pounded—bombed by aircraft, shelled by ships.

Chunks of concrete lay everywhere. Buildings were hollow shells.

And yet Japanese soldiers moved through the ruins, rifles over their shoulders.

They weren’t dug into fixed positions. No big bunkers, no clear defensive lines.

They were using the town as a staging area—a kind of forward camp for counterattacks against the American lines.

Frank needed more detail.

How many men? How were they armed? Where were the supply dumps?

At 1605, he made one of those decisions that later gets you written up in history books and whispered about at reunion dinners.

He and four others would go into Garapan.

In daylight.

Not sneaking from shadow to shadow.

Riding bicycles.

At 1708, Kazzy—Corporal Irazi from Brooklyn, who’d earned his nickname by “requisitioning” half the Army’s beer on Maui one weekend—spotted five bicycles leaning against a shattered wall.

Japanese military issue.

Officers’ transport.

“Five bikes, five of us,” he said, grinning.

Frank considered it.

Five Marines in grubby uniforms trying to sneak through a ruined town would stick out.

Five men on bikes, not trying to hide, just moving with the flow?

Less suspicious.

Insane, but less suspicious.

“All right,” he said. “We stick to one rule. If anyone speaks to you in Japanese, you smile and wave like you understood every word.”

Strombo snorted. “What if they ask us a question, sir?”

“Then you nod,” Frank said, “and keep pedaling.”

At 1715, they mounted up and pedaled into the town.

They rode past Japanese troops digging in.

Past officers shouting orders.

Past soldiers carrying crates into buildings that had not taken much shell damage.

They kept their posture loose. No hunched shoulders, no furtive looks.

Once, an officer waved at them and shouted something in Japanese.

Kazzy waved back, flashed a grin that would have sold used cars in Brooklyn, and kept going.

For 43 minutes, the five Americans rode through the enemy’s capital, counting heads, watching for supply piles, noting where communication wires ran, mapping where fresh troops seemed to be congregating.

Then they pedaled out the other side, rode another mile north for good measure, ditched the bicycles behind a low wall, and disappeared back into the jungle.

By 1932, they were back inside Marine lines.

Fourteen hours behind enemy lines. Two major objectives reconned. No losses.

After that, no one in the regiment called them “criminals” with quite the same tone.

For three more weeks, the 40 Thieves did what they had been built to do.

They slipped out into the jungle in twos and threes and fives.

They mapped caves and bunkers.

They watched Japanese officers with binoculars and called down artillery on headquarters they’d just watched accept a dispatch.

They ambushed patrols when they had to. They faded away when they could.

They saw things they would never fully put into words—Japanese civilians jumping from cliffs rather than be captured, wounded Marines used as bait for ambushes, prisoners executed by machete.

They ran out of food and stole from Japanese supply dumps.

They ran out of water and drank from streams that made them sick.

They sweated through malaria chills and shivered under tropical rainstorms.

They lost twelve men killed and nine wounded by the time Saipan was declared secure on July 9th.

Thirty-seven men had moved out from the beach that first day.

By the end, their casualty rate was 56%.

Lower than the 73% the stats said it should be.

Still more than enough to haunt dreams.

Marine commanders later estimated their reconnaissance had reduced overall casualties on Saipan by at least fifteen percent.

Roughly 2,000 lives.

Two thousand kids from Pennsylvania, Texas, California, New York who went home who otherwise might not have.

The forty thieves went on to fight on Tinian in July.

They came back to Saipan for “mopping up,” which mostly meant rooting pockets of desperate holdouts out of caves.

Then the war rolled on without them as the fleet pushed toward Iwo Jima and Okinawa.

After the war, there were no parades specifically for scout sniper platoons.

Most of the 40 Thieves went home and tried to be something like normal.

They had nightmares.

They drank.

Some bounced from job to job, too restless to sit in an office for long.

No one talked about “post-traumatic stress disorder” yet. They just called it “shell shock” or “battle fatigue” and expected men to shake it off.

Frank Tachsky went back to the Midwest.

He eventually became mayor of Sturgeon Bay, Wisconsin—a small town job that involved zoning disputes, pothole complaints, and the occasional argument about parade routes.

He almost never talked about the 40 Thieves.

He didn’t brag about Saipan at rotary lunches. He didn’t tell war stories to reporters.

His son, Joseph, knew his dad had been a Marine.

He didn’t know his father had led an elite platoon that had crept two miles beyond the front line and ridden bicycles through an enemy capital like it was a Sunday outing.

Not until he found an old footlocker in 2011, after Frank died.

Inside were letters.

Maps.

Photos.

A faded platoon roster.

Forty names, many crossed out in red.

A story that had changed Marine Corps doctrine and then been mostly forgotten for 66 years.

The scout sniper platoon of the Sixth Marine Regiment never wore SEAL tridents or Special Forces tabs.

Those didn’t exist yet.

But the tactics they pioneered—the idea that a small group of highly trained men could go far behind enemy lines, operate independently, kill silently, shape a battle bigger than themselves—that idea would filter forward.

Into Marine Force Recon.

Into the Navy’s Underwater Demolition Teams, and later the SEALs.

Into every special operations unit that learned to send in a few quiet professionals instead of a thousand men with rifles.

Forty men, recruited from punishment details and brigs.

Forty “criminals” the Corps didn’t quite trust.

They became one of the most effective small units in the Pacific War.

The Marines who’d written them off were wrong.

They weren’t criminals.

They were exactly the kind of fighters the war required.

They were thieves.

They stole time from the Japanese battle plans.

They stole pillboxes from machine-gun crews.

They stole tanks from banzai charges.

Most importantly, they stole death itself from a couple thousand of their fellow Americans who walked back onto ships and went home.

And somewhere, if you believe in that sort of thing, there’s a colonel from Tarawa watching them and thinking, That experiment worked.

THE END
