German tank crews encountered the “Jumbo” — and realized that not every “Sherman” was the same.-ZZ

July 27th, 1944, Normandy, near the town of Viller Facade.

German tank commander Ernst Barkman took aim at another Sherman.

The distance, 600 m, perfect for his Panther.

He pulled the trigger.

The 75 mm shell hit the front of the American tank’s turret.

Direct hit.

But instead of an explosion, just a shower of sparks, a ricochet.

This is impossible, Barkman thought, reloading.

The second shot, another ricochet.

The third, same result.

The American tank turned its turret.

One shot and the shell pierced the Panther’s armor.

Barkman survived, but that moment haunted him for the rest of his life.

His proud Panther, the terror of all Shermans, had proved powerless.

German crews didn’t yet know they were facing a new enemy, the M4 A3E2.

The tank the Americans called simply and proudly, Jumbo.

By the summer of 1944, German tankers believed in one rule.

The Sherman was easy prey.

The numbers confirmed it.

For every destroyed German tank, the Americans lost on average three and a half Shermans.

But in June 1944 at the Fisher Tank Arsenal plant in Grand Blanc, Michigan, production began on a machine that would change the rules of the game.

Its official designation M4 A3E2.

Weight 38 tons compared to the usual 30.

Front armor 102 mm instead of 51.

Side armor 76 instead of 38.

Colonel Gladian Barnes, the project’s chief engineer, wrote in his report, “We are not building a new tank.

We are building a shield for our boys.

In just 2 months, June and July, only 254 units were built.

Less than 1% of all Shermans, but those few became the nightmare of German anti-tank gunners.

” Veteran of the US Third Armored Division, John Irwin recalled, “When we got the first jumbos, the Germans didn’t even understand what was happening.

They shot at us like at regular Shermans and just watched their shells bounce off.

The jumbo wasn’t just a modification.

It was the answer to the bloody lessons of Africa and Italy, where American crews paid with their lives for every meter of advance.

December 1943.

Office of the Chief Engineer of Fiser Body Division.

On the table, photos of knocked out Shermans from Tunisia, Sicily, and Italy.

penetrations from German 75 and 88 mm guns.

60% of hits to the front 20 to the turret, the rest to the sides.

Major General Gladon Barnes had been staring at the pictures for 3 hours.

Next to him sat William Nudson, former president of General Motors.

“We need a breakthrough tank,” Barnes said.

“A machine that will go first and take the hit.

” “We can just reinforce the Sherman’s armor,” Kenudson replied.

But the weight will go up.

How much? About 8 tons.

Barnes fell silent.

The standard 4 GAAA engine, 500 horsepower, was already barely enough for the 30 ton tank.

With eight more tons, speed would drop to 35 kmh.

Do it, he finally said.

Better a slow tank than a dead crew.

On December 15th, the T2062 project received official approval.

The task was simple.

to create a heavily armored variant of the M4 A3 for breaking through fortifications.

Engineers worked non-stop.

The frontal armor was increased from 51 to 102 mm.

A double layer of rolled homogeneous steel.

The turret was reinforced to 152, the gun manlet to 178, but the added weight exposed a weak point, the transmission.

On the third day of testing, the gearbox failed.

On the 5th, the differential broke.

Engineer Robert Andrews suggested using the system from the yet unfinished heavy tank T26 Persing.

But that project existed only on paper.

They had to improvise.

Added support rollers widen tracks from 42 to 58 cm strengthened the torsion bars.

On March 1st, 1944, the first prototype rolled out at the Aberdine proving ground in Maryland.

Weight a little over 38 tons.

Speed 35 kmph on road, 16 off-road.

March 5th, 1944.

Aberdine proving ground 7 a.

m.

-3° C.

Four tanks lined up, a standard M4 A3.

The new M4 A3E2, a captured Panther, and a Tiger.

Colonel David Eisenhower, cousin of the Supreme Commander, led the tests.

The goal to see if the new armor could withstand German gunfire.

First shot, 75mm KWK42 gun from the Panther.

Distance 500 m.

Hit to the front.

Only a dent 38 mm deep.

Armor held.

Second shot 300 m.

Lower glacis plate.

Depth 67.

Still no penetration.

Third from the Tiger’s KWK 3688 mm gun.

distance 700 m.

The shell penetrated the edge of the frontal armor, the only spot where thickness was only 76.

In his report, Eisenhower wrote, “The M4 A3E2 demonstrated exceptional resilience.

I recommend immediate production, but problems remained.

The weight made the tank sluggish.

On soft ground, it bogged down.

On the second day, the Jumbo got stuck in the mud.

It had to be pulled out by two Shermans in an M32 recovery vehicle.

Driver mechanic Sergeant Thomas Miller joked, “Driving this thing is like dragging a concrete slab.

You have to yank the levers with both hands.

” Commander Lieutenant George Wilson added, “Visibility is awful.

Through those narrow slits, you can see maybe 30°.

” March 15th, the final test.

The M4 A3E2 was put against a captured PAC 43, the most powerful anti-tank gun in the Vermacht arsenal.

First shot from 1,000 m.

Ricochet, second from 800, dent 89 mm deep, third from 600, full penetration through the gun mantlet.

The conclusion was clear.

The jumbo could withstand nearly anything except a direct hit to the mantlet or a pointblank shot.

June 1st, 1944.

Fisher Tank Arsenal, Grand Blanc, Michigan.

At 6 in the morning, the first armor plate, 102 millime thick, was laid on the welding table.

Worker Joseph Kowalsski, a Polish immigrant, switched on the welding machine.

The ark temperature, over 3,000° C.

His team of 12 assembled one tank hole per day.

The factory employed 890 people in three shifts, and nearly 40% of them were women.

19-year-old welder Rosie Montgomery recalled, “We understood.

Every tank meant lives saved.

A poster on the wall read, “Your work is their armor.

We worked 12-hour days and didn’t complain.

Production ran at a furious pace.

In the first week, 18 tanks.

In the second, 31.

By the end of June, 127 vehicles.

But not everything was perfect.

The armor plates were supplied by US steel and Bethlehem steel and the quality of the steel varied.

Out of the first batch of 200 plates, 43 were rejected, too brittle because of high sulfur content.

Quality engineer Paul Anderson introduced a new test.

Every plate was fired upon with a captured German PAC 38 anti-tank gun of 50 mm caliber.

If the armor cracked, the batch went back to the smelting plant.

On June 15th, tragedy struck during turret welding and acetylene cylinder exploded.

Three workers were killed.

Production stopped for one day.

The next morning, plant director Benjamin Keller gathered the crew in the main workshop.

Every day of delay costs the lives of our boys in Normandy.

We don’t have the right to stop.

And they didn’t.

By the end of July, the plant met its target completely.

254 jumbos.

The final M4 A3E2 serial number 42,76,554 rolled off the line on July 31st at 2345.

Someone had written in chalk on its turret, the last of the Moheakans.

July 18th, 1944.

Omaha sector Normandy Second Tank Battalion, 66th Armored Regiment.

Sergeant Lester Johnson opened the hatch of his new tank.

Painted in white letters on the side was the name Cobra King.

“It was one of the first 10 jumbos to reach the French front.

” “What is this beast?” asked driver Bill Harris, running his hand over the thick armor.

“Our ticket home,” Johnson replied.

“At 1,400 hours, the battalion received its order.

Break through the German defenses near the village of Sanjil.

Reconnaissance warned at least three anti-tank guns and two stooguji assault guns.

The jumbo went first, followed by regular Shermans 50 meters behind.

At 1437, the first shot, a German PAC 40 opened fire from 400 m.

The shell struck Cobra King’s frontal armor.

Inside, only a dull thud.

Armor piercing at the flash, shouted Johnson into the intercom.

Gunner Corporal David Smith aimed and pulled the trigger.

The 75mm M61 shell hit the gun shield dead center.

A powerful explosion.

The crew was wiped out.

From the right flank, a second Paw 40 opened fire.

The shell hit the side, the most vulnerable spot.

The tank shuttered, but the armor held, spinning the vehicle 30°.

“Turn right.

Show them the front,” ordered Johnson.

The machine pivoted to face the enemy.

The next three shots bounced off the armor like peas off a wall.

At 1515, the battalion broke through the first defensive line.

Losses, two knocked out Shermans and one jumbo with a broken track.

The Germans lost four guns and one Stew G Thur.

Major James Leslie, the battalion commander, wrote in his log, “The M4 A3E2 performed brilliantly.

Firepower and armor aren’t the key, it’s the effect.

The Germans can’t believe their shells are bouncing off.

July 27th, 1944.

Hill 122 near Viller Facade.

6:00 in the morning.

Fog lay over the fields.

Visibility no more than 100 m.

The crew of Jumbo number 31 from the 743rd Battalion ate cold rations.

Tank commander Lieutenant Charles Boyce scanned the distance with binoculars.

“Too quiet,” he muttered.

At 6:43, the fog began to lift.

In the distance, 800 meters away.

A silhouette appeared.

A panther, and not just any panther.

It was the tank of Oberfeld Weeble Ernst Barkman, an ace with 53 kills.

Barkman also spotted the jumbo, but mistook it for a standard Sherman.

A fatal mistake.

The first shot, a 75mm Pasgra 39/42 shell struck the center of the frontal armor.

Ricochet.

Barkman froze.

At that distance, he had always pierced Sherman’s clean through.

Second shot at the turret.

Again, sparks again.

A ricochet.

Fire.

Ordered Boyce.

The jumbo shell couldn’t penetrate the Panther’s frontal armor, but Boyce aimed lower at the running gear.

Hit.

The idler wheel was shattered.

The drive sprocket damaged.

The Panther turned its side.

The worst thing it could have done.

The next shot pierced the 40mm side armor.

Inside, the ammunition detonated.

Four crew members jumped from the burning tank.

Barkman was among them, wounded in the leg.

Later, the radio operator of that tank, Corporal Curt Meyer, was captured.

During interrogation, he said, “The commander was in shock.

He kept repeating, “This is impossible.

This is impossible.

” He couldn’t understand why the shells wouldn’t penetrate.

American intelligence recorded it as the first documented victory of the M4A3E2 over a Panther in direct combat.

August 4th, 1944.

Operation Cobra, the breakout from Normandy.

The US 30th Infantry Division was advancing toward the town of Mortaine.

In front, four jumbos from the 743rd Battalion.

The commander of the lead tank, fearless Staff Sergeant William Mcnite, guided the vehicle through the narrow streets.

Every corner could be a trap.

At 11:15, they rolled into the central square and were met with a storm of fire.

From the windows of nearby buildings, three Panzer Fousts fired simultaneously.

Two hit the front, one struck the turret.

The explosions rocked the tank, but the armor held.

“High explosive, the windows!” shouted Mcnite.

The jumbo 76 mm gun.

Some tanks had already been refitted with the more powerful barrels.

Fired an H round into the second floor.

The wall collapsed, burying the German grenaders under rubble, but the ambush had been well planned.

From a side street emerged a Stoooji 4.

A shot from 50 m.

A direct hit to the side.

The shell pierced the 76 mm armor and fire erupted.

Inside, loader John Kelly and radio operator Paul Anderson were killed instantly.

Mcnite, the gunner, and the driver escaped through the top hatch as flames burst from the turret.

The remaining three jumbos returned fire.

Within 30 seconds, the Stew Gifu exploded, turning into a burning mass of twisted steel.

By evening, Mortain was taken.

Of the four jumbos, one destroyed, two damaged.

But they had achieved their purpose.

They had cleared the way for the infantry.

Major General Leland Hobbes wrote in his afteraction report, “Without these heavy tanks, we would have lost at least a company of infantry.

Each jumbo is worth a platoon of regular Shermans.

December the 16th, 1944.

The Arden, the start of the German counter offensive.

Temperature minus 20° C.

Snow was falling in thick sheets.

The US Fourth Armored Division was retreating under German pressure.

In the column were three jumbos, including one tank bearing the name Fury of the First Lady.

Its commander, Sergeant Robert P, received an order.

Cover the retreat.

At 1,400 hours, the Germans appeared on the road.

Ahead, two King Tigers from the Heavy Tank Battalion, 56th.

P knew his 75mm gun couldn’t penetrate the front armor of a King Tiger, even at point blank range.

But there was nowhere to run.

The Germans fired first.

An 88 mm shell from the long barrel KWK43 slammed into the Jumbo’s frontal plate.

The armor cracked but held.

Inside, white dust fell from the zinc coating, shaken loose by the impact.

Smoke screen, ordered pool.

Two smoke shells created a dense white wall.

The jumbo veered sharply right, hiding behind a fold in the terrain.

The Tigers lost their target and began to maneuver around the flank.

Pool wasn’t going to wait.

He shouted to the driver, Private James Davis, full speed into the woods.

The tank lunged into the forest.

38 tons of steel smashed through young trees like matchsticks.

German infantry followed close behind.

Suddenly, the jumbo burst onto a concealed position of an 88mm anti-tank gun.

Distance 30 m.

The Germans had no time to turn the barrel.

The jumbo simply rolled over the gun with its tracks.

The crunch of metal, the screams of the crushed crew.

At 1600 hours, Pool’s tank rejoined friendly lines.

On the frontal armor, 11 dents from hits on the turret.

Seven more.

But fury of the first lady had made it back.

January 1945, repair base of the 654th Tank Battalion, Belgium.

Technical Sergeant Howard Cooper examined a damaged jumbo.

On the armor, 23 marks of various calibers.

Not a single penetration.

“This is unbelievable,” he said to his assistant.

“Any other Sherman would be a civ by now.

” Cooper knew the M4 3E2’s design down to the last bolt.

The secret wasn’t just in the thickness.

The front plate was sloped at 47° giving an effective thickness of about 140 mm.

Plus, extra 38 mm applique plates were added over the most vulnerable areas.

The turret was a masterpiece of casting.

One solid piece with no weld seams.

Thickness at the front 152 mm, sides 76, and the gun mantlet a massive 178.

Still, the heavy turret turned slowly.

Manual traverse, one full rotation in 40 seconds, electric in 15.

The Panther could do it in about 9.

Cooper started experimenting.

He installed a more powerful electric motor taken from a B7 bomber.

Now the turret turned in 11 seconds.

Another issue, visibility.

The commander’s cupula had only six narrow slits, giving a field of view of about 180°.

Mechanic Private Tom Watson came up with a solution.

He welded a periscope from a submarine onto the cupula.

The commander now had a full 360° view.

The weakest point remained the suspension.

The VVSS, vertical volu suspension system wasn’t built for 38 tons.

Springs snapped every 200 km.

Cooper replaced the standard springs with reinforced ones from a railway car.

The mountings had to be modified, but the results were worth it.

By February 1945, his team had upgraded 47 tanks.

Each was unofficially nicknamed Super Jumbo.

March 7th, 1945.

The Ludenorf Bridge over the Rine in the small town of Raagan.

The US 9th Armored Division was racing toward the river.

The Germans were preparing to blow up the bridge, the last one still connecting both banks.

Leading the column was the jumbo commanded by Lieutenant Carl Timberman.

Behind him followed two more heavy tanks.

At 1550, they reached the riverfront.

The bridge stood intact, but on the opposite bank, gun barrels gleamed from bunkers and concrete pillboxes.

Forward, full speed, shouted Timberman into the intercom.

The jumbo thundered ahead.

38 tons of steel roared across the steel truss spans.

The bridge shook under every tread.

From the far bank, a 20 mm flack 38 opened fire.

A burst of explosive shells peppered the tank.

Sparks flying like a brief firework.

Gunner Sergeant Anthony Delissio returned fire with the machine gun.

Within seconds, the flack gun fell silent, then a muffled explosion.

The Germans had detonated the charges under the bridge, but something went wrong.

The blast was strong, yet the spans held.

The bridge trembled and was enveloped in smoke.

The jumbo burst through the haze, infantry following close behind.

On the far side, two panzer shots struck the frontal armor.

Both left deep dents, but no penetration.

Timberman leapt from the hatch and charged forward with the assault troops, taking German positions one after another, meter by meter.

By 1600 hours, the bridge was secured.

It was the first Allied crossing of the Rine, the moment that opened the road into the heart of Germany.

Timberman’s Jumbo became the first American tank to cross the river.

Later, it was shipped to the United States and placed in a museum as a symbol of the moment when the Fortress of the Rine lost its invincibility.

April 14th, 1945, the town of Oberdorf, Bavaria.

Private Clarence Smoyer drove his jumbo down a narrow street lined with old houses.

It was already his third tank.

The Germans had burned the previous two Shermans.

At the corner, he saw a familiar shadow, a gun barrel, a Tiger 6 distance, 25 m, point blank.

Both tanks fired at the same time.

The Tiger’s 88 mm shell struck the Jumbo’s gun mantle.

The thickest part of its armor, 178 mm of steel.

The shell lodged there, failing to penetrate.

Smooyer’s tank, now armed with a 76 millimeter gun, fired back.

The shell hit the joint between the Tiger’s turret and hull.

A flash erupted.

The armor cracked.

Then the ammunition detonated.

The Tiger’s turret was blown off and hurled 10 m away.

No one came out of the burning wreck.

Smooyer wiped sweat from his forehead, his hands trembling.

“We got him!” yelled Gunner Corporal Homer Davis.

But the joy lasted only seconds.

From a basement nearby, a Panzer Foust rocket streaked out, hitting the left track and tearing it apart.

The jumbo lurched, crashed through a wall, and stopped inside a building.

Inside were German soldiers.

In panic, they fired their rifles at the armor.

The bullets bounced off harmlessly like hail on tin.

Smooyer swung the turret and fired a burst from the machine gun.

The Germans fled through the back door.

At 1700 hours, a repair team arrived.

Within an hour, the track was fixed.

Captain John Marsh, the company commander, personally inspected the tank.

A German shell was still lodged in the mantlet, a dent 127 mm deep.

Another 51 and it would have punched through.

Lucky Smooyer, the captain said a point blank hit from a Tiger.

No other Sherman would have survived.

Historians later confirmed this was the last documented battle between a jumbo and a tiger in the Second World War.

April 1945, a military hospital in Reigns, France.

Sergeant Donald Bernett lay in a hospital bed.

Both legs and casts, concussed, eardrums ruptured.

His jumbo had hit a mine a week earlier.

The tank survived.

The crew did not.

Of the five men inside, two were killed instantly.

One died on route to the hospital.

The armor saved the tank, but not us,” Bernett told the nurse bitterly.

“It was a harsh truth.

The jumbo was rarely penetrated, but crews often died from concussions, internal blasts, or fire.

Statistics for April 1945.

Of the 254 vehicles produced, 51 were destroyed completely, 89 seriously damaged, 114 survived with minor damage.

Crew casualties, 187 killed, 342 wounded, 89 concussed.

Tankman Martin Bell recalled, “When an 88 hit us, the tank jumped like a living thing.

Everything inside flew.

I saw the gunner killed by his own sight.

The blast tore it off and slammed it into his face.

” Lieutenant Peter Ross added, “The worst part was evacuation.

The hatches were narrow because of the thick armor.

If the tank caught fire, you had 20 seconds to get out.

Not everyone made it, but there were other stories.

Staff Sergeant William Crane recounted, “My jumbo took 31 hits in one battle.

Yeah, we were concussed.

It was hell inside, but we lived in a regular Sherman.

We’d have burned after the first shot.

May 8th, 1945.

Pleasen, Czechoslovakia.

Sergeant Robert Early’s Jumbo stood in the central square.

The war had ended 2 hours earlier.

On its armor, 44 dents from shells.

The front plate cracked in three places.

The right track held together by sheer luck, but the tank had made it from Normandy to Czechoslovakia.

2,847 km.

Early sat on the turret smoking around him.

Czech children gathered, staring at the giant machine.

“Mister, is that a real tank?” a boy asked in broken English.

“Yes, kid.

Real.

The best in the world?” Early smiled.

But he knew the truth.

The Jumbo wasn’t the best.

Slow, clumsy, with a weaker gun than the Panther and worse maneuverability than the T-34, but it did what it was built for.

To go first, to take the hit, and to give others a chance to survive.

Of the 254 produced, 163 survived to see the end of the war.

They had gone from the beaches of Normandy to the banks of the Elby.

Driver mechanic James Parker calculated that his tank had taken 67 direct hits, a record among all American machines.

At 1600 hours, the order came to assemble all jumbos and pulsen for inspection.

47 tanks arrived, some barely moved.

One had half a track missing.

Another had lost its gun, torn off by a direct hit.

But they made it.

Heavy, slow, nearly blind, yet indestructible.

General Patton inspecting the battered machines said, “These tanks saved more lives than all the medics of the Third Army combined.

” June 1945, American Vehicle Collection Point, Marseilles, France.

157 jumbos that had survived the war stood in neat rows across a field.

The army was deciding their fate.

At first, part of them were to be sent to the Pacific.

Preparations were underway for the invasion of Japan, but the atomic bombs changed everything.

On August 15th, Japan surrendered.

The jumbos were no longer needed.

Engineer Corps Captain Thomas Wright was assigned to inspect the tanks and recommend a course of action.

Of the 157 machines, 23 were beyond repair, 67 required major overhauls, 54 were in satisfactory condition, 13 were almost untouched.

Wright advised scrapping the destroyed ones, repairing the usable ones, and transferring them to the Allies.

But Washington decided otherwise.

The jumbos were deemed too heavy for transport, too complex to maintain, and too expensive to operate.

On September 1st, dismantling began.

The tanks were cut apart with torches, their armor sent for smelting.

Sergeant Michael O’Brien, a tank veteran, stood and watched as his jumbo, the Avenger, was cut to pieces.

the tank that had carried him from Normandy to Germany.

“It’s like watching an old friend being killed,” he said quietly.

“Yet a few tanks were saved.

One jumbo was sent to the Patton Museum at Fort Knox.

Another went to the Aberdine proving ground.

A third was gifted to France, becoming a monument in Straborg.

30 more were sold to Belgium and France.

They remained in service until 1952.

The last operational jumbo was decommissioned on March 15th, 1952.

It was cut up for scrap in Lion.

Today, only four authentic M4A3E2 jumbos remain in the world.

One stands in the Armor Museum at Fort Benning, Georgia.

Its armor still bears the scars of German shells, 31 dents.

Each one marks a life saved.

The second rests in the patent museum at Fort Knox, the same cobra king that broke through to the surrounded town of Bastonia during the Battle of the Bulge.

The third belongs to a private collection in France.

Collector Jacques Littlefield bought it from the French army in 1987 for 50,000 Franks.

The tank is still operational.

The fourth was found at the bottom of the Moselle River in 2003.

It had lain underwater for 58 years.

It is now being restored in Germany.

254 machines.

Out of 49,000 Shermans, only half a percent.

But those few tanks changed the course of many battles.

They led the assaults that broke the Ziggfrieded line.

They were the first to enter German cities.

They covered the retreats in the Arden.

Veteran Joseph Demler, a jumbo.

Gunner wrote in his memoirs, “We weren’t heroes.

The heroes were the guys in the light Shermans who followed behind us.

We just had thicker armor.

But the numbers tell another story.

The average crew survival rate in a jumbo after being hit, 71%.

In a regular Sherman, 38%.

German tank ace Autocarius, credited with 150 victories, recalled, “When we saw those heavy Shermans, we knew there would be no easy victory.

You either had to flank them or pull back.

The M4 A3E2 was not perfect.

It was a compromise.

Armor at the cost of speed.

Protection at the cost of maneuverability.

Survival at the cost of comfort.

But sometimes a compromise is exactly what war demands.

When the choices between speed and life, between maneuver and a chance to come home.

The jumbo chose life.

And it saved thousands.

General Omar Bradley wrote after the war, “If we’d had not 254 but 2540 of these tanks, we’d have ended the war 3 months earlier and saved 50,000 lives.

” Maybe he was right, maybe not.

But for those who fought in the jumbo, who hid behind its armor, who followed it into battle, this tank remained forever a symbol.

A symbol that sometimes to win, you don’t need to be the fastest or the strongest.

Sometimes it’s enough to take the hit and keep moving step by step, meter by meter, from Normandy to the Elb.

Heavy, slow, almost blind, but indestructible.

Jumbo, the tank that refused to
