German POWs in Idaho Were Shocked When American Ranchers Using “Salt Licks” to Control Cattles

The cattle came without being forced.

Thousands of them moved across the high desert plateau, a river of brown and black and white flowing through the sage brush toward a destination none of them could see.

No whips drove them forward.

No fences channeled their movement.

No dogs snapped at their heels.

They simply walked, drawn by something invisible, something the German prisoners watching from the ridge could not yet understand.

It was July 1944.

The sun hung fierce and white over the Snake River plain, baking the volcanic soil and turning the distant mountains into shimmering miragages.

The temperature had already climbed past 90°, and the prisoners, 12 men from Camp Roupert, assigned to a ranching work detail, stood in the sparse shade of a juniper tree, watching what appeared to be a miracle of animal management.

A single rancher on horseback guided the herd.

One man, perhaps 2,000 cattle, and they moved as if they wanted to go where he was taking them.

Heinrich Brener, a former sergeant in the Vermacht’s 15th Panzer Division, wiped the sweat from his forehead and stared at the scene unfolding below.

He had managed supply convoys in North Africa.

He understood logistics, understood the challenge of moving large numbers of anything troops, vehicles, animals across hostile terrain.

What he was watching made no sense.

The rancher’s name was Tom McCriedy.

He was 57 years old, a third generation Idaho cattleman whose family had worked this land since the 1880s.

His face was leather and squint lines, his hands permanently curved to the shape of rains.

He had been running cattle across these high desert ranges since before most of the prisoners were born.

And he did it, Brener would soon learn, with salt.

The prisoners had been brought to the McCreaty ranch to help with summer operations, mending fences, maintaining water systems, general labor that the war had made impossible to hire locally.

The young men were gone fighting in Europe and the Pacific.

The old men and the women kept things running, but they needed hands.

German hands, enemy hands.

McCreaty had been skeptical at first.

These men had been trying to kill Americans until recently.

Some of them might still want to, but the county agricultural agent had explained the Geneva Convention, the security arrangements, the practical necessity.

And McCriedi, like ranchers everywhere, was a practical man.

He needed workers.

They needed work.

The mathematics were simple.

What he had not anticipated was their fascination with his methods.

The salt licks were placed strategically across the range.

Large blocks of compressed mineral salt positioned at intervals that McCriedi had calculated over decades of experience.

The cattle craving the minerals their grazing could not provide would seek them out.

And in seeking them they would move from the winter range to the spring pastures, from the spring pastures to the summer highlands.

From the highlands back down as autumn cooled the air.

The entire cycle of the ranching year was orchestrated not through force but through understanding.

understanding what the animals wanted, what they needed, and how to make the path of least resistance lead exactly where you needed them to go.

It was, Brener realized, a form of control more complete than any fence or whip could achieve.

The cattle thought they were choosing freely.

In a sense, they were, but their choices had been shaped, their desires anticipated, their movements predicted, and guided by a man who understood them well enough to make them want what he wanted.

The German sergeant stood on the ridge, watching 2,000 head of cattle follow a single rider toward a destination they could not see, and felt something shift inside his chest.

A photograph exists in the Idaho State Historical Society archives.

It shows a group of men standing near a corral in what appears to be high summer.

Some wear the working clothes of ranch hands, broad-brimmed hats, dusty boots, sun-faded shirts.

Others wear simpler garments, workc clothes that lack the personalization of men who chose their own attire.

The light is harsh, casting sharp shadows.

In the foreground, barely visible, sits a white block the size of a cinder block, a salt lick.

The photograph is labeled PW work detail, Minidoka County, 1944.

No names are attached, no identification of which men are prisoners and which are ranchers.

The caption offers no narrative, no explanation of what the men were doing or what they thought about it.

But the photograph captures something nonetheless.

A moment when enemies stood together, learning from each other in the vast quiet of the Idaho range.

Camp Roert was one of several prisoner of war facilities that operated in Idaho during World War II.

Located near the town of Paul in Minidoka County, it served as a branch camp under the administration of Camp Farraragut to the north.

At its peak, it held several hundred German prisoners, primarily Vermach soldiers captured in North Africa and Italy.

The camp sat in the heart of Idaho’s agricultural region, surrounded by irrigated farmland and vast stretches of high desert range.

The Snake River plane stretched in all directions, flat, dry, treeless, except where irrigation had created artificial oases of green.

The Sawtooth Mountains rose to the north, their peaks still snowcapped even in summer.

The landscape was alien to men who had grown up in the forests of Bavaria or the industrial cities of the rur.

But it was the ranching that captured their attention.

Germany had farms.

Germany had livestock.

But Germany did not have this this vast emptiness where a single family might run cattle across ranges larger than entire German counties where management was accomplished not through the brute force of enclosure but through the subtle manipulation of animal behavior.

The prisoners watched.

They questioned.

They struggled to understand.

And in their struggle they encountered something that challenged more than their understanding of agriculture.

Hinrich Brener had been a believer, not a Nazi, he had never joined the party, had distrusted the fanatics who rose to power in the 1930s.

But he had believed in German efficiency, German organization, German superiority, in the practical arts of management and control.

The Vermach had conquered Europe not through ideology but through logistics, through the careful orchestration of men and machines into a system of overwhelming force.

He had been proud of that system.

He had been part of it.

Now he stood on an Idaho ridge, watching an old man on a horse move 2,000 cattle with nothing but salt and patience, and wondered if everything he had believed about power and control had been wrong.

The cattle followed because they wanted to follow.

They moved because moving served their own desires, and in the end they arrived exactly where the rancher needed them to be, not because they had been forced, but because they had been understood.

It was a different kind of power, a quieter kind, and watching it work, Brener felt the first stirrings of a question he was not yet ready to ask.

What if persuasion was stronger than force? To understand what the German prisoners encountered on the Idaho ranges, one must first understand the world they came from.

The Vermacht had conquered Europe through discipline and force.

The German military machine was built on precise command structures, unquestioning obedience, and the systematic application of overwhelming power.

When the Reich needed something moved troops, supplies, populations, it moved them through orders backed by the threat of punishment.

This was the model Heinrich Brener understood.

This was the world that had shaped his thinking.

But the American West operated on different principles.

The ranching economy of Idaho had developed over nearly a century by 1944.

Beginning in the 1860s, cattlemen had discovered that the high desert ranges of the Snake River plane, despite their apparent barrenness, provided excellent grazing for livestock, adapted to aid conditions.

The native grasses were nutritious.

The winters, though cold, were often dry enough that cattle could forage year round with minimal supplementation.

But the scale was staggering.

A single ranch might encompass hundreds of thousands of acres, much of it federal grazing land leased from the government.

Moving cattle across such distances required methods fundamentally different from the enclosed pastures of European agriculture.

You could not fence a range that size.

You could not station enough men to drive herds by force alone.

You had to work with the animals, not against them.

The salt lick system had evolved over generations of trial and observation.

Ranchers learned that cattle, like all animals, would work to satisfy their own needs, provide what they craved, mineral supplementation, water, shade at the locations where you wanted them, and they would move themselves.

No coercion required.

It was management through incentive, control through understanding, and it worked.

The Geneva Convention of 1929 required that prisoners of war be given opportunities for labor, compensated fairly, and not employed in work directly supporting military operations against their own country.

Agricultural work met these requirements perfectly.

By 1944, the western states faced critical labor shortages.

Young men who would normally work the ranches and farms were serving overseas.

The harvests needed bringing in.

The cattle needed tending.

The infrastructure of food production essential to both the civilian population and the military supply chain required hands that were not available.

Prisoner of war labor filled the gap.

At camps throughout Idaho, Roupert Wilder, Nampa, and others German prisoners were assigned to agricultural details.

They harvested potatoes, the state’s signature crop.

They picked sugar beats.

They maintained irrigation systems.

And on the rangeands of southern Idaho, they worked alongside cattlemen who had developed methods unlike anything the prisoners had ever seen.

A report from the Provis Marshall General’s Office in 1944 noted that prisoners assigned to ranching operations in Idaho demonstrate high levels of engagement and productivity.

The report attributed this partly to the outdoor conditions which prisoners preferred to indoor factory work and partly to the novelty of American agricultural methods which appear to generate significant interest among the prisoner population.

The bureaucratic language obscured a more profound truth.

The prisoners were learning things that changed how they thought about the world.

Camp Roupert was established in 1943 as a branch facility focused on agricultural labor.

The layout was typical of Western P camps, wooden barracks arranged in compounds separated from the surrounding community by wire fencing, but not heavily fortified.

Guard towers stood at intervals staffed by older soldiers or those deemed unfit for overseas combat.

The atmosphere was more agricultural than military.

The daily routine revolved around work.

Prisoners rose at 5:30, ate breakfast at 6:00, and assembled for work details at 6:30.

Trucks transported them to farms and ranches throughout the region, often 30 or 40 m from the camp.

They worked until late afternoon, returned for dinner at the camp Messaul, and had evening hours for recreation, education, or rest.

The food was adequate, sometimes better than adequate.

A prisoner letter from Camp Roupert, preserved in the National Archives, describes the provisions with evident surprise.

We eat meat every day.

There are potatoes in quantities I have never seen.

This is apparently a region famous for potatoes.

We receive coffee with real sugar.

I have gained weight since arriving.

I do not think my family would recognize me.

The letter continued with observations about the work itself.

Today, we helped move cattle on a large ranch.

The methods are unlike anything in Germany.

They use blocks of salt to make the animals want to go where they need them.

No one beats the cattle or forces them.

They simply follow the salt.

I am still thinking about what this means.

The ranchers who employed prisoner labor had their own adjustments to make.

Many had sons fighting overseas.

Some had lost family members to German submarines or German bullets.

The idea of working alongside the enemy was not easy to accept.

But practical necessity overrode emotional resistance.

Tom McCriedi’s son was serving with the army in Italy fighting against Germans who might have been the comrades of the men now working his range.

He thought about this sometimes, watching the prisoners repair fences or haul water to remote stock tanks.

He thought about the strange reversals of war, the way it scrambled categories and confused allegiances.

But he also thought about cattle, 2,000 head that needed moving from the winter range to summer pastures, stock tanks that needed cleaning, fences that needed maintenance across hundreds of miles of rangeand.

These things did not wait for the war to end.

They demanded attention now, and the prisoners, whatever else they were, could work.

The relationship between ranchers and prisoners evolved along predictable lines.

Initial weariness gave way to working routine.

Language barriers remained.

Most prisoners spoke limited English.

Most ranchers spoke no German.

But the work itself created a shared vocabulary.

Point at a fence post.

Hand someone a tool.

demonstrate a technique.

The meaning became clear.

McCriedi found himself explaining things he had never put into words before.

The salt lick system was intuitive to him, learned from his father, who had learned it from his father.

He had never thought about why it worked, only that it did.

But the prisoner’s questions forced him to articulate principles he had absorbed without examination.

Why do the cattle want the salt? Because their grazing does not provide enough minerals.

They crave what they lack.

Why do they remember where the salt is? Because cattle are not stupid.

They learn.

They remember.

Why do they come even when they are far away? Because want is stronger than distance.

If the desire is strong enough, they will travel.

McCriedi was not a philosophical man.

He did not think in abstractions.

But answering the prisoner’s questions, he found himself describing something more than ranching technique.

He was describing a theory of motivation, a model of behavior, a way of understanding how living things could be guided without being forced.

The prisoners listened.

They watched.

They thought about what they were learning.

and slowly, imperceptibly, they began to see the cattle differently and themselves and the world they would eventually return to.

The first turning point came during a water system repair.

The prisoners had been assigned to help maintain the network of stock tanks and pipelines that brought water to remote areas of the mccreati range.

It was hard, hot work, digging in the volcanic soil, clearing debris from sistns, patching leaks in pipes that ran for miles across the desert.

Hinrich Brener worked alongside a man named Carl Vogle, a former school teacher from Munich, who had been conscripted into the Vermacht late in the war.

Vogle was thoughtful, quiet, given to observations that the other prisoners sometimes found uncomfortable.

The water is like the salt, Vogel said during a rest break, looking at the pipeline they had just repaired.

They put it where they want the cattle to go.

The animals come because they need water.

No one forces them.

Brener nodded.

It is efficient.

It is more than efficient.

Vogle wiped his forehead with a dirty cloth.

It is a philosophy.

They understand what the animals want and they arrange the world so that wanting leads where they need it to lead.

He paused, looking out at the distant cattle grazing peacefully around a stock tank.

We thought we could control through force, through orders, through fear, but look at this.

A few salt blocks, a few water tanks, and one man moves 2,000 cattle.

Brener did not answer immediately.

He was thinking about the convoys he had managed in North Africa, the military police, the rigid schedules, the constant threat of punishment for deviation.

He had moved supplies efficiently, but always through the application of pressure.

McCriedi moved cattle through the release of pressure.

He created conditions where the cattle wanted to do what he needed them to do.

It is a different kind of power, Brener finally said.

Yes.

Vogle looked at him directly.

And I think it may be stronger.

The conversation stayed with Brener through the following weeks.

He watched McCriedy work.

He observed how the rancher positioned himself relative to the herd, never directly behind, pushing, but always at an angle, guiding.

He noticed how the cattle were allowed to set their own pace, how the movement seemed almost voluntary, even when it led to specific destinations, and he began to see parallels that extended far beyond animal husbandry.

The Vermacht had conquered through force, through the application of overwhelming military power.

It had worked for a time, but now the Reich was crumbling.

The force that had seemed irresistible, was meeting resistance it could not overcome.

Meanwhile, the Americans, these casual, disorganized, seemingly inefficient Americans, were winning the war.

Not through the brutal precision of the German war machine, but through something else.

Through production, through persuasion, through making people want to support the war effort rather than simply commanding their obedience.

The war bond drives that the prisoners heard about on the radio.

The scrap metal campaigns that mobilized entire communities.

The women who had entered factories not because they were ordered to, but because they wanted to contribute.

It was Brener realized the same principle as the salt lick.

Create conditions where people want to do what you need them to do.

Arrange incentives so that self-interest aligns with collective purpose.

Let them think they are choosing freely and in a sense they are.

But their choices have been shaped by a hand they cannot see.

A letter from a prisoner at Camp Roupert, preserved in the Idaho State Historical Society archives, captures this emerging understanding.

I have been thinking about what I have seen here.

The Americans do not manage their country the way we were taught a country must be managed.

There is no central authority directing every action.

People seem to do as they wish and yet somehow the necessary work gets done.

The prisoner continued, “On the ranch, I watch how they handle the cattle.

No force, only incentive.

The animals go where they are needed because going there serves their own desires.” I wonder if this is how America itself works.

Millions of people, each following their own wants, somehow producing a result that serves the whole.

The letter concluded with a question that military sensors apparently found unthreatening enough to allow.

If this is true, then perhaps we misunderstood what we were fighting.

Perhaps we were not fighting a weak nation at all, but a strong one, strong in a way we did not know how to see.

McCriedi noticed the change in the prisoners.

Their questions became more sophisticated.

They asked not just how things were done, but why.

They wanted to understand the reasoning behind the methods, the principles that made them work.

One evening, after the work was done, and the prisoners were waiting for the truck to return them to camp, McCriedi found himself in an unusual conversation with Brener.

Their English had improved enough for basic exchange.

“You ask many questions,” McCriedi observed.

We want to understand, Brener said.

Understand what? How to run cattle? Brener considered his words carefully.

How you run everything? The cattle, the ranch, the country.

McCriedi laughed a short surprised sound.

I don’t run the country.

I just run this ranch.

But the principle is the same.

Yes.

Brener gestured at the range stretching around them.

You do not force the cattle.

You give them what they want, and they go where you need.

McCriedi was quiet for a moment.

He had never thought about his methods as reflecting any larger truth.

He just did what worked.

“I suppose that’s right,” he finally said.

“You can drive cattle, but it’s harder.

They resist.

They scatter.

You wear them out and you wear yourself out.

Better to let them walk on their own.” He looked at the German prisoner, this former sergeant who had once helped conquer North Africa.

Maybe people are the same way,” McCriedi added.

“I wouldn’t know about that.” But Brener was already nodding.

He knew he was learning.

The summer wore on toward autumn.

The prisoners continued their work on the ranch, and the questions continued.

Word spread among the P population at Camp Roupert about the unusual methods they had witnessed.

Other prisoners returning from other work assignments shared their own observations.

The Americans, it seemed, had developed countless systems that relied on incentive rather than compulsion.

The sharecropping arrangements that motivated agricultural workers.

The profit sharing programs that made factory workers invested in productivity.

The volunteer organizations that accomplished what in Germany would require government mandates.

A report from the War Department’s Special Projects Division dated October 1944 noted the effect these observations were having on prisoner attitudes.

Prisoners exposed to American agricultural and industrial methods frequently express revised opinions regarding the comparative strengths of German and American systems.

Several prisoners have noted that American reliance on voluntary cooperation rather than centralized direction appears to produce results comparable or superior to German methods.

The report recommended that such exposure be encouraged as part of the broader re-education effort aimed at preparing prisoners for eventual repatriation to a democratic Germany.

The bureaucratic language as always understated the human reality.

Men who had been raised to believe in the power of force were watching that belief erode salt block by salt block, day by day in the high desert of Idaho.

The season changed.

As September arrived, the days shortened and the nights turned cool.

The cattle, responding to some ancient calendar written in their blood, began drifting toward the lower ranges where they would spend the winter.

McCriedi and his crew, including the prisoners from Camp Roupert, prepared for the final gather of the year.

The work was different now than it had been in July.

Brener and the others moved through it with understanding, not just obedience.

They knew why the salt licks were positioned where they were.

They knew why the water tanks mattered.

They could predict where the cattle would be based on principles they had learned to see.

And on the last day of their assignment to the McCreaty ranch, as the autumn light turned golden across the sage brush, something remarkable happened.

McCriedi asked Brener to place a salt block.

It was a simple task, but it carried meaning beyond the practical.

The rancher was trusting the prisoner not just to work, but to understand.

He was treating him as someone who had learned, who could make decisions, who grasped the principles well enough to apply them without supervision.

Brener carried the heavy block to the position mccrady had indicated a slight rise, where cattle moving from the north would naturally encounter it.

He set it down, positioning it carefully to be visible from a distance.

McCreaty watched, then nodded.

“Good,” he said.

“They’ll find it.” It was a small moment, a block of salt placed on a desert hillside, but Brener understood what it represented.

He had become, however briefly, part of something that worked, something that achieved results not through force, but through understanding, something that treated even animals as beings with desires worth respecting.

The war ended in stages, as it always did.

Germany surrendered in May 1945.

The prisoners at Camp Roupert and the other Idaho facilities learned the news through official announcements and radio broadcasts.

The reactions were mixed.

Relief, grief, uncertainty about what awaited them in a homeland they could barely imagine.

Repatriation was slow.

The logistics of returning hundreds of thousands of men to a shattered Europe took months to organize.

The Idaho camps began emptying gradually, their populations shipped east to processing centers and then across the Atlantic.

Heinrich Brener was repatriated in the spring of 1946.

He returned to a Germany divided into occupation zones, its cities in ruins, its people struggling to rebuild.

The family apartment in Cologne had been destroyed by bombing.

His parents had survived by relocating to relatives in the countryside.

He found them there older and thinner than he remembered.

Living in two rooms of a farmhouse that had belonged to strangers before the war.

He did not return to military life.

The Vermach no longer existed, and he had no desire to resurrect his connection to it.

Instead, he became a teacher.

The choice was influenced, he later admitted, by what he had learned in Idaho.

Not the technical skills he would never run cattle, never place salt licks across a high desert range, but the principle, the understanding that people, like animals, responded better to incentive than compulsion.

That motivation outperformed fear.

that true management meant understanding what others wanted and creating conditions where their wants aligned with your needs.

He taught mathematics in a gymnasium in Dudeldorf and later became an administrator.

His colleagues noted his unusual approach to discipline he rarely punished preferring to structure situations so that students wanted to behave appropriately.

Let them think they are choosing.

He once told a younger teacher who asked about his methods.

Make the right choice the easy choice.

They will make it and they will think it was their idea.

The younger teacher did not understand the reference when Brener added quietly, “I learned it from the cattle in Idaho.” Tom McCreaty continued ranching until 1967 when declining health forced him to turn operations over to his son, the same son who had fought in Italy while German prisoners worked the family range.

The transition was seamless.

The younger McCreaty had learned the same methods his father had learned, the same methods his grandfather had developed.

The salt licks remained in their positions across the range.

The cattle continued their seasonal movements guided by desires they could not question toward destinations they could not see.

McCriedi died in 1972 at the age of 85.

His obituary in the Twin Falls Times News mentioned his long career as a cattleman, his service on the county agricultural board, his membership in the cattleman’s association.

It did not mention the German prisoners who had worked his range during the war.

By 1972, that chapter seemed too distant to matter, a footnote in a life defined by larger concerns.

But the family remembered in interviews conducted by the Idaho State Historical Society in the 1980s.

McCriedi’s grandchildren recounted stories.

Their grandfather had told, stories of German soldiers who asked endless questions about salt and water and cattle who seemed fascinated by methods that to him were simply the way things had always been done.

He said they learned something out there, one grandchild recalled, not just about ranching, about how things work, about what makes people do what you need them to do without making them.

Today, the high desert ranges of southern Idaho look much as they did in 1944.

The sage brush still covers the volcanic soil.

The mountains still rise to the north, snowcapped in winter and autumn.

The cattle still move across the landscape in patterns determined by salt and water and the ancient logic of grazing animals.

The P camps are gone.

Camp Roupert was dismantled after the war, its barracks removed, its land returned to agricultural use.

Only historical markers and archived photographs testify that it ever existed.

But somewhere in the archives in Idaho, in the National Archives, in the private collections of families who saved letters and documents, the story persists.

The story of men who came as enemies and left with something changed inside them.

Who learned on a remote Idaho range that there were forms of power beyond force.

Who watched cattle follow salt blocks across the desert and saw in that simple image a truth that would reshape how they understood the world.

The cattle did not know they were teaching philosophy.

They simply wanted the salt.

They simply moved toward what they desired.

And in their movement they showed men who had believed in force that persuasion could be stronger.

That understanding could be more effective than compulsion.

That the quiet arrangement of incentives might accomplish what no army ever could.

The salt licks remained where McCreaty had placed them.

The cattle came.

They always came.

And in their coming, a lesson endured, written not in books, but in the behavior of animals who never knew they were part of a story that crossed oceans and decades and transformed the lives of men who had come to destroy and stayed to Fun.
