July 4th, 1946.
Biskupia Górka Hill, Gdańsk, Poland.

A 24-year-old woman stands trembling on the back of a military truck.

A noose hangs around her neck.
Her hands are tied behind her back.
Thousands of people stare at her in silence.

Beside her stand other condemned female concentration camp guards.

Within minutes, all of them will be hanging dead before one of the largest public execution crowds in postwar Europe.

Her name is Wanda Klaff.

And only weeks earlier, during her war crimes trial, she shocked the courtroom with a statement so cold-blooded that even some fellow defendants reportedly stared at her in disbelief.

“I am very intelligent and very devoted to my work in the camps. I struck at least two prisoners every day.”

Not apology.

Not remorse.

A boast.

THE JAM FACTORY WORKER WHO BECAME A CAMP GUARD

Wanda Klaff was born on March 6th, 1922, in the Free City of Danzig — today’s Gdańsk, Poland.

She grew up in an ordinary working-class German family.

No criminal history.
No known record of violence.
Nothing that predicted what she would become.

She finished school at 16 and went to work in a jam factory.

The life waiting for her seemed painfully ordinary:

Factory shifts.
Marriage.
Domestic life.

In 1942, she married and became a housewife.

Then, in 1944, something changed.

“SHE VOLUNTEERED”

At age 22, Wanda Klaff volunteered to become an SS female guard at the Stutthof concentration camp system.

Nobody forced her.

She chose it.

She was assigned first to the Praust subcamp near Danzig, where prisoners were already dying from starvation, disease, overwork, and brutality.

By the time Klaff arrived, Stutthof had become a nightmare.

More than 110,000 prisoners would pass through the camp system during the war.

Approximately 65,000 would die.

And survivors later remembered Wanda Klaff specifically.

That alone said something horrifying.

THE GUARD WHO BEAT PRISONERS “EVERY SINGLE DAY”

As an overseer, Klaff supervised female prisoners during labor assignments, roll calls, and barracks inspections.

But witness testimony described something far beyond ordinary camp discipline.

Survivors said she beat prisoners constantly:

With rubber hoses.
With sticks.
With whips.
With boots and fists.

Women collapsing from exhaustion were kicked.

Prisoners working too slowly were struck repeatedly.

The violence became routine.

Daily.

And then came the statement that destroyed her forever.

“I STRUCK AT LEAST TWO PRISONERS EVERY DAY”

During her 1946 trial, Wanda Klaff openly admitted:

“I struck at least two prisoners every day.”

At least two.

Every day.

By her own words, that meant hundreds of assaults in less than a year as a guard.

But what horrified the courtroom even more was her tone.

She did not sound ashamed.

She sounded proud.

THE CAMP OF DEATH

Stutthof had originally been created in 1939 for Polish prisoners and resistance members.

But by 1944, transports of Jews and prisoners from across occupied Europe flooded into the camp system.

Conditions collapsed.

Starvation spread.
Disease exploded.
Executions became constant.

Prisoners worked brutal shifts in factories and construction sites under freezing Baltic weather.

And guards like Wanda Klaff enforced obedience through terror.

THE WOMAN WHO ENJOYED HER POWER

Survivors later testified that Klaff seemed to enjoy inflicting pain.

Not because she was ordered to.

But because she wanted to.

That distinction became critical during her trial.

Her lawyers attempted the standard defense:

“She was only following orders.”

But prosecutors argued that Wanda Klaff exceeded what was required.

No regulation demanded she beat prisoners daily.

That was her own initiative.

And her own testimony confirmed it.

THE COLLAPSE OF THE THIRD REICH

By early 1945, Soviet forces were closing in on Danzig.

The SS began evacuating Stutthof and its subcamps.

Prisoners were forced onto death marches westward.

Others were packed onto overcrowded ships in the Baltic Sea — some later sunk with thousands aboard.

SS personnel tried desperately to destroy evidence.

Wanda Klaff fled back to Danzig hoping to disappear into the civilian population.

She likely believed she could simply become an ordinary housewife again.

But survivors remembered her face.

THE ARREST IN A HOSPITAL BED

While hiding in Danzig, Klaff contracted typhoid fever and was hospitalized.

On June 11th, 1945, Polish authorities arrested her in the hospital after former prisoners identified her as one of Stutthof’s brutal guards.

The trial began in April 1946.

And witness after witness pointed directly at Wanda Klaff.

THE STATEMENT THAT SHOCKED THE COURTROOM

Many Nazi defendants tried to minimize their crimes.

Klaff did the opposite.

When given the chance to defend herself, she proudly declared:

“I am very intelligent and very devoted to my work in the camps.”

Then she repeated the line about beating prisoners every day.

The courtroom reportedly fell silent.

Even among war criminals, her lack of remorse stood out.

DEATH BY PUBLIC HANGING

The court sentenced Wanda Klaff to death by hanging for crimes against humanity.

Appeals for clemency failed.

Polish authorities decided the executions would be public.

Special gallows were built on Biskupia Górka Hill near Gdańsk.

Huge crowds gathered to watch.

Some estimates claimed over 100,000 spectators.

Many were survivors of Nazi camps themselves.

THE FINAL MINUTES OF WANDA KLAFF

On July 4th, 1946, military trucks transported the condemned prisoners to the execution site.

Klaff stood on the truck bed with a rope around her neck.

Former Stutthof prisoners reportedly assisted with placing the nooses.

Then the signal was given.

The truck engines roared.

And the vehicles pulled forward simultaneously.

Wanda Klaff dropped.

THE EXECUTION THAT SHOCKED THE WORLD

The execution used a short-drop hanging method.

That meant no instant neck break.

Death came slowly through strangulation.

Witnesses watched as the condemned struggled for air.

Photographs captured the horrifying scene:

Bodies twisting.
Faces turning dark.
Dozens of thousands staring upward in silence.

The images spread internationally and became some of the most disturbing photographs of postwar justice.

THE LAST PUBLIC EXECUTION IN POLAND

The spectacle disturbed even Polish authorities.

The enormous crowd.
The graphic deaths.
Children reportedly watching from shoulders in the crowd.

After Biskupia Górka, Poland abandoned large-scale public executions.

Future hangings would happen behind prison walls.

Wanda Klaff’s death became one of the final major public executions in modern Polish history.

THE TERRIFYING PART OF HER STORY

Historians remain disturbed by Wanda Klaff for one reason above all:

She was ordinary.

Not a senior Nazi commander.
Not a famous ideologue.
Not a lifelong criminal.

Just a factory worker and housewife who volunteered for power over helpless people…

…and discovered she enjoyed cruelty.

That is what makes her story so frightening.

Not that she was born a monster.

But that an ordinary person could become one so quickly — and proudly.
