When you think of the Holocaust, you probably recall the overwhelming horror already documented in countless histories. Yet there are still many sinister things the Nazis inflicted on camp inmates that rarely make the headlines. Below we dive into nine chilling practices that reveal just how far the regime pushed cruelty.

Sinister Things Exposed

9 Sonderkommanden

Simply put, a Sonderkommando was a prisoner forced to deal with the dead. Their grisly duties included extracting gold teeth from corpses and sweeping away the ashes left behind. Because they weren’t Nazis, they were ordinary inmates.

Their misery deepened because they were labeled “Geheimnisträger” (secret‑keepers), making them too dangerous to keep alive for long. They were routinely murdered and replaced every few months without warning, often having to dispose of the very person they were replacing.

8 The Trains

Moving thousands of people to the camps required a massive, horrifyingly efficient transport system. Although a single carriage was meant to hold about 50 passengers, it was not uncommon to cram more than 200 into one car.

Travelers received no food, water, or shelter from the elements, and many perished en route. One train that left Corfu took 18 days to arrive, and when the doors opened, every passenger inside had already died.

7 The Trains (Again)

How could the Nazis make the death trains even more dreadful? By charging victims for their passage. To reach an extermination camp, a Jewish person had to purchase a standard‑fare ticket.

Children under four were the only exception—the Nazis waived the fee for them, but everyone else paid for the privilege of being shipped to their doom.

6 The Music

The Nazis turned music into a weapon of psychological torture. Upon arrival, a prisoner‑made orchestra would blare upbeat tunes that inmates were forced to sing and march to as they headed toward death.

The orchestra kept playing even as gas chambers operated, though no amount of music could drown out the victims’ screams. Survivors carried the guilt of this twisted soundtrack for decades.

5 Human Soap

It was a widely spread myth that Nazis forced Jews to use soap made from the fat of Holocaust victims. No conclusive evidence ever proved the claim, yet the Nazis spread the story to break prisoners’ spirits.

In reality, the regime did experiment with making soap from human remains, but it was rarely, if ever, used on inmates.

4 Starvation And Dark Cells

Not every victim received a quick death; many were forced to stand in rooms without food or water until they died. Block 13 of Auschwitz became infamous for this method, and anyone who survived starvation was later killed another way.

Even worse were the “dark cells” – sealed chambers with no light, where occupants slowly suffocated as the limited oxygen was used up.

3 Lack Of Food

Daily rations for prisoners were pitiful: bread made from sawdust, sausage from emaciated horses, and tea brewed from weeds. Hunger drove inmates to steal food from the dead, and in extreme cases, some resorted to eating rotted garbage.

2 Lack Of Water

Among the many experiments, Dr. Hans Eppinger forced about 90 Gypsy inmates to drink only seawater to observe its effects. The result was severe dehydration; prisoners even licked freshly mopped floors for a single drop of fresh water.

1 The Experiments

The full scope of Nazi cruelty may never be known because many records were destroyed. Nonetheless, human experimentation was not only common—it was encouraged.

Prisoners were submerged in ice water to test hypothermia, injected with chemicals and poisons, sterilized, vivisected, and operated on without anesthesia. This list merely scratches the surface of their atrocities.

The term “concentration camp” has become synonymous with Nazi Germany—and rightfully so—but we often forget about the obscure concentration sites that existed before and after World II. If you think of Stalin’s gulags or Cambodia’s killing fields, you’re only seeing the tip of the iceberg; there are dozens of forgotten camps that were just as shocking.

Why These Obscure Concentration Sites Matter

Understanding these hidden prisons helps us grasp the full scale of human rights violations across the globe and reminds us why vigilance is essential.

9 Sri Lankan Concentration Camps

There’s ongoing debate over whether the facilities set up during the Sri Lankan Civil War were genuine concentration camps or, as the government called them, “welfare centers.” In reality, civilians were herded into these sites for “protection” while the war raged around them. The displaced were labeled internally displaced persons (IDPs) rather than detainees, but the fact remains: they were confined against their will with scant provisions, fitting the definition of an internment camp.

Human‑rights groups such as Amnesty International, along with aid agencies, condemned the deplorable conditions. Their pressure forced the authorities to allow limited freedom of movement for IDPs. Officially, the camps shut down in 2012, yet estimates suggest around 100,000 people still linger in the remnants or transit centers.

8 Spain’s ‘Reconcentration’ Camps In Cuba

By 1896, the Spanish Empire was losing its grip on rebellious Cuba. General Valeriano Weyler—dubbed “Butcher Weyler”—introduced a reconcentration strategy: rural Cubans were rounded up, told they were being protected, and shipped to camps where food and shelter were minimal. Citizens had just eight days to report, or they faced execution.

The camps quickly devolved into death traps. Over 400,000 Cubans perished from disease, starvation, and exposure, earning the grim moniker “Cuban Holocaust.” Graphic reports of skeletal, naked populations reached the United States, fueling the fire that led to the 1898 Spanish‑American War.

7 Cuba’s Camps For ‘Social Deviants’

After the island’s own experience with Spanish reconcentration, Cuba in the 1960s turned inward, imprisoning its own citizens without trial. Counter‑revolutionaries and so‑called “deviants”—including homosexuals, people with HIV/AIDS, Jehovah’s Witnesses, and others—were rounded up by authorities under Che Guevara’s direction.

Thousands of gay men were forced into labor camps where the chilling motto “work will make you men” echoed. In the sugar fields and other forced‑labor sites, inmates endured humiliation, torture, hunger, and death. Many chose suicide over the relentless misery, and the overall environment resembled Stalin’s gulags.

6 Britain’s Concentration Camps In South Africa

During the South African (Boer) War of 1900–1902, British forces tried to crush Boer resistance by interning women and children in 45 camps across the region. Over 107,000 black South Africans were also forced into these sites, many ending up as forced labor.

When General Herbert Kitchener took command, the policy turned brutal. He ordered a scorched‑earth approach, herding thousands of civilians—women, children, and black people—into overcrowded, under‑supplied camps. Disease ran rampant; measles, typhoid, and other illnesses claimed countless lives. Roughly 26,000 women and children died, along with an estimated 14,000 black inmates.

5 US Concentration Camps In The Philippines

While the British were busy in South Africa, the United States was consolidating its hold on the Philippines after the Spanish‑American War. During the Philippine‑American War, American forces ordered entire villages to relocate to concentration camps, threatening lethal force for those who resisted.

The policy mirrored the earlier Spanish reconcentration in Cuba, with burned villages and rampant disease. About 300,000 Filipinos were corralled under gunpoint, and estimates suggest roughly 20 % of the population perished in some of those camps.

4 Vietnam’s Reeducation Camps

When the Vietnam War ended, the victorious North Vietnamese government forced former South Vietnamese soldiers, bureaucrats, and anyone suspected of anti‑socialist sentiment into “reeducation” camps. Though advertised as short‑term stays, detainees often spent three to ten years in these prisons.

The camps were brutal: inmates were beaten, shackled, forced to confess imagined crimes, and subjected to relentless propaganda. Hard labor—digging wells, clearing jungles, sweeping minefields—was the daily norm. Death from disease and starvation was common; an estimated 165,000 perished.

3 Chile’s Dawson Island Camp

Beyond Stalin’s Siberian gulags, Dawson Island in the Strait of Magellan served as a chilling prison outpost. First used in the 1800s to detain the Selknam people, the isolated island later became a military prison after Chile’s 1973 coup, housing high‑profile political prisoners from the Allende era.

Life there was a nightmare: scant food, no clean water, grueling labor, and minimal medical care. Even in sub‑zero temperatures, inmates were denied blankets and proper clothing. The Red Cross investigated in 1974, prompting the camp’s closure and the transfer of prisoners to mainland facilities.

2 Portugal’s Tarrafal Camp In Cape Verde

After centuries of serving as a slave‑trading hub, Cape Verde became the site of the infamous Tarrafal Camp—nicknamed the “Camp of the Slow Death.” Created in 1936 by Portuguese dictator António de Oliveira Salazar, it housed communists, anarchists, anti‑colonialists, liberals, and anyone opposing his regime.

Prisoners from temperate Europe were forced to endure scorching tropical heat. The notorious “frying pan” was a concrete box that baked inmates under the relentless sun. International pressure forced the camp’s closure in 1954, but it reopened in the 1970s to imprison African independence leaders. The facility grew into a fortress with moats, barbed wire, and even Nazi‑inspired torture chambers. The Carnation Revolution finally freed the remaining prisoners.

1 Bosnia‑Herzegovina’s Omarska Camp

During the 1992–1995 Bosnian War, Bosnian Serb forces set up a network of concentration camps to purge non‑Serbs. Omarska, one of the most notorious, detained between 5,000 and 7,000 Bosniak and Croat civilians.

In a grotesque media stunt, Serb authorities allowed journalists a brief glimpse of the camp’s dining hall, only to reveal emaciated prisoners with hollow eyes—images that shocked the world and forced the camp’s closure within a month.

Before it shut, detainees were forced to live in an open‑pit iron mine, exposed to the elements and packed so tightly that lying down was impossible. Approximately 2,000 inmates died from the brutal conditions, and bodies were reportedly stacked so high that forklifts were needed to move them.

The Bosnian genocide claimed roughly 100,000 lives, half of them Bosniaks, and war‑crime trials continue to this day.

The following horrifying accounts expose the brutal world of North Korea’s prison camps, where any perceived misstep can land a person in a forced‑labor nightmare.

Horrifying Accounts Unveiled

10 Il

Jeong Kwang-il was a trader who struck deals with South Koreans in China, an act the North Korean law brands as consorting with the enemy. Accused of espionage, he was hauled to a prison camp where interrogators sought a confession through brutal torture. His teeth were shattered, and a heavy blow scarred the back of his head.

The infamous “pigeon torture” was inflicted on him: his hands were cuffed behind his back, the cuffs hoisted him so his feet dangled in the air. He endured this suspended position for days, a pain so intense he thought death would be a mercy. After ten months of relentless torment, he finally confessed to fabricated crimes.

Jeong was shipped to Yodok, one of the largest camps, home to roughly 50,000 inmates. A sign at the gate warned newcomers: “Let’s sacrifice our lives to protect the revolutionary leadership of Dear Leader Kim Jong Il.”

Life in Yodok began at 5 a.m. with a meager bowl of rice, beans, and corn. Prisoners were then forced into grueling labor. In spring, they had to till about 1,170 sq m (12,600 ft²) of field each day, with food cuts for anyone who fell short. Winter work meant hauling massive logs over three kilometres, many dying from accidents or starvation when injured.

Jeong survived three years until a senior guard recognized his wrongful accusation. Upon release, he discovered his home vanished and his family gone. Within a month he escaped North Korea and fled to South Korea.

9 Jihyun Park

Jihyun Park’s father fell ill, prompting her mother to bribe border guards and slip the family across the river into China. A broker promised a decent job, but Park was instead sold as a wife to an alcoholic farmer for 5,000 yuan (≈ $750). She endured six years of slavery, toiling sixteen hours a day, finding solace only in her son, Chol.

When Chol was five, authorities arrested Park and deported her back to North Korea, where she was dumped into a labor camp. Conditions were “unspeakable,” with inmates forced to work like animals. Inmates had to clear hills of trees for planting, and they weren’t allowed shoes. The rough stones broke the skin on Park’s feet, leading to infections and gangrene.

Guards eventually decided they wanted her to “die outside the prison camp,” releasing her. Though her wounds healed slowly, she still walks with a limp. Park escaped to China, reunited with her son, fell in love with another defector, and the three of them secured asylum in Britain.

8 Kang Cheol Hwan

Kang Cheol Hwan’s grandfather was declared a traitor, forcing the entire family into a prison camp. At just ten years old, Kang entered Yodok and saw children so emaciated they looked worse than beggars.

He was promptly sentenced to hard labor, carrying massive logs on his shoulder for miles. If an inmate lagged, guards ordered the rest of the workgroup to beat the sluggish prisoner.

Refusing a guard’s order meant being sent to a “prison within the prison” – a six‑month stint in a tiny cell where detainees were forced to sit in cold, muddy water. Few survived the micro‑prison.

Kang witnessed two soldiers attempt escape; both were captured and hanged. Thousands of prisoners were then ordered to line up, march past the bodies, and throw rocks while shouting “Down with the traitors of the people!” Those who refused to hurl stones were beaten.

After a decade in the camp, Kang’s family was released. Five years later, he and another former prisoner escaped to China and eventually boarded a ship to South Korea.

7 Soon

Kim Young‑soon once danced for Kim Il Sung, the nation’s founding father. One day, secret police summoned her, locked her in a room, and interrogated her for two months about senior party officials. She claimed ignorance, yet she, her four young children, and her parents were hauled to Yodok.

Rations were scarce: prisoners received only small portions of corn and salt. Failure to meet daily work quotas meant reduced rations. Inmates supplemented their diet with anything edible—rats, salamanders, snakes—often eaten raw because there was no time or means to cook.

Malnutrition left everyone weak. Kim watched people “drop down dead every day” and saw most of her family perish. She survived nine harrowing years until a visiting military official, who recognized her brother, secured her release. With forged documents, she crossed into China and eventually reached South Korea.

Later, Kim discovered the reason for her imprisonment: she had once been friends with Sung Hye‑rim, the first wife of Kim Jong Il. Because Sung’s marriage to the leader was scandalous, officials erased anyone who knew her, imprisoning them en masse.

6 Ahn Myong Chol

Ahn Myong Chol spent over a decade as a prison guard. He was trained to treat prisoners as non‑human and was encouraged to kill any inmate who tried to escape.

Guards who killed escapees earned rewards, prompting many to shoot innocent people just to secure college placements. Ahn witnessed a colleague order a prisoner to climb a barbed‑wire fence; the guard shot the prisoner and then left for college.

Violence was sometimes senseless. Two girls tried to retrieve noodles from a polluted pond; a guard kicked them into the water, drowning both. In another horrific episode, three dogs broke loose and attacked five children—three died instantly, and the remaining two were buried alive while the guards petted the dogs and fed them special food as a reward.

Ahn’s own father made a few drunken, negative remarks about the leadership, leading to his family’s detention. Fearing a similar fate, Ahn drove his truck to the shore, swam to China, and later fled to South Korea.

5 Il

Kim Kwang‑Il was starving and resorted to gathering pine nuts to sell across the Chinese border. He was caught, arrested, and accused of smuggling. During interrogation, he was forced into bizarre positions—pretending to ride a motorcycle or be a plane—until he sweated enough to fill a glass placed beneath him.

If a prisoner fainted, interrogators claimed they were faking and made them start over. Overwhelmed, Kim eventually confessed and received a six‑year sentence.

In the camp, he was tasked with moving heavy logs up a mountain without any machinery. The work was perilous; rolling logs crushed inmates, breaking bones. When corpses piled on a cart, prisoners hauled the full cart up the mountain, shoved the bodies into a pot, set it ablaze, and later used the ashes as fertilizer for the fields.

Kim was released after serving 29 months and later managed to escape to South Korea.

4 Jin

Lim Hye‑jin spent seven years as a prison guard. At age 20, two brothers escaped the camp; in retaliation, seven of their family members were beheaded on the spot. The guards then forced prisoners to throw stones at the freshly severed heads.

Lim also observed rampant sexual violence. Guards would rape any female prisoner they chose. Pregnant victims were forced to have abortions; if the pregnancy was advanced, the guards beat the newborns to death or burned them alive.

In one chilling interrogation, a guard grew angry with a female prisoner, stripped her naked, and set her on fire—without any disciplinary consequence. Guards were taught to view prisoners as “just animals.”

Lim herself was caught trading in China, sentenced to a short term, and later forced to parade naked before male guards. She finally fled the country and reached safety in South Korea.

3 Soon Ok Lee

Soon Ok Lee served as director of the Government Supply Office for fourteen years, overseeing food and material distribution. When the North Korean economy stalled, she was scapegoated as the cause of the populace’s starvation. She endured months of torture until she confessed, hoping to protect her husband and son.

After the confession, she and her family were dispatched to a forced‑labor camp. Guards berated prisoners, saying, “You are not human beings. You must think that you are beasts; otherwise you will not survive.”

At the camp, she worked in an ironworks factory under scorching heat, causing her spine to shrink, her back to curve, and her shoulder bones to protrude. A mistake—hiding a faulty shirt—landed her in a tiny “punishment cell” where she could neither stand nor lie down. The ordeal left her unable to walk properly for weeks after release.She endured further beatings with leather straps, head kicks, broken teeth, facial paralysis, and chronic headaches. After seven years, she was freed. A few years later, she and her son escaped to South Korea via China.

2 Hyuk Kim

Hyuk Kim was a homeless 16‑year‑old who trekked to China in search of food. Caught and sentenced to three years, he quickly lost any sense of humanity, describing himself as “like an animal… No thinking. No free will. Just fear.”

His day began at 7 a.m. with a handful of cornmeal and 50‑90 soybeans for breakfast. He labored until noon, received another tiny meal, then returned to work. Dinner arrived at 7:30 p.m., followed by a mandatory memorization of camp rules. A single mis‑spoken word forced the entire team to stay up until they could recite the regulations perfectly. Lights out came around 10 p.m.

Food obsession dominated his thoughts. Occasionally, he caught a rat, skinned it, dried the meat, and ate it raw. Attempting to cook the rats attracted guard attention, resulting in savage beatings.

Some inmates bartered for cigarettes—highly coveted contraband. They scrounged half‑smoked guard butts, reconstituted the tobacco, and fashioned new cigarettes. Getting caught making or smoking these was met with severe beatings.

After eight months, Hyuk was released and escaped to South Korea.

1 A

Ji Hyeon‑A attempted to flee North Korea for China three times, each ending in capture and forced return. The third time, she was pregnant. The regime does not tolerate mixed‑race babies; anyone who becomes pregnant in China is forced to abort. At a local police station, Ji underwent a forced, medication‑free abortion.

She was then sent to a labor camp, where she witnessed the brutal treatment of other pregnant women. Inmates were compelled to perform hard labor, and Ji heard mothers scream at night as they miscarried under the strain.One harrowing incident involved a woman who gave birth after an eight‑hour workday. The joyous moment was cut short when a guard ordered the newborn to be drowned. The mother pleaded, but obeyed the command.

Ji eventually secured her release, escaped North Korea, and was reunited with her family.

These 10 horrifying WWII internment stories show that while the Japanese American camps are widely known, they were just one chapter of a far broader tragedy. Governments worldwide rounded up civilians from enemy nations and locked them inside camps on virtually every front.

10 Canadian Internment Camps Were Worse Than The American Ones

Across the border in Canada, the same sweeping order that sent Japanese Americans to detention sites also swept up the 23,000 people of Japanese descent living in the north. Their experience, however, often eclipsed the American ordeal in cruelty.

Authorities stripped them of every personal item and promised that their belongings would be held “in trust” until peace returned. That promise proved hollow; within six months of confinement, the government auctioned off all seized property without consent.

Many of the Canadian sites were little more than repurposed barns and chicken coops, crudely insulated with tar paper. Prisoners received no beds, only straw‑filled sacks riddled with fleas to lie upon.

The winter of 1942‑43 set records for cold in British Columbia, with temperatures plunging below –40 °C (–40 °F). Internees were forced to pack dirt against the thin walls just to keep the bitter cold at bay.

While the United States began releasing Japanese civilians back to their homes in 1944, the Canadian government kept its detainees locked up until April 1949, a full five years after the war’s end.

Even then, many never returned home. Officials pushed the remaining internees to relocate to Japan, and roughly 4,000 were deported before a single person was truly freed.

9 The US Also Interned Italian, German, Taiwanese, And Korean Civilians

The Japanese were not the sole target of America’s wartime internment machinery. Under the same executive order, Taiwanese and Korean residents were classified as Japanese and swept up as well.

Roughly 11,500 German‑American and 2,700 Italian‑American civilians found themselves behind barbed wire solely because of their ancestry. Estimates vary, with some scholars suggesting the Italian figure could be as high as 10,000.

Although these numbers represent a small slice of each community, the selection process was often absurd. For instance, Joe DiMaggio’s father, a long‑time U.S. resident, nearly faced internment because he had not yet secured citizenship.

Hundreds of thousands more endured strict curfews. Over 600,000 Italian‑Americans who escaped the camps were still forced to stay indoors between 8 p.m. and 6 a.m.

The climate could have been far worse. A 1944 poll revealed that a significant portion of Americans supported turning internment into an outright genocide, with 13 % endorsing the killing of every Japanese person in America, children included.

8 Jewish Refugees In Britain Were Interned And Deported

When Germany seized Norway in 1940, a wave of paranoia rippled through Great Britain. Anyone of German or Italian descent was branded an “enemy alien” and confined.

The majority of those detained were Jewish refugees who had fled Nazi persecution. Of the 80,000 enemy aliens held, 55,000 were such refugees—people who had narrowly escaped concentration camps only to be locked away by the nation that promised them safety.

Families were split apart; for the first year, men and women were housed in separate facilities, preventing spouses from seeing each other.

Additionally, 7,000 were expelled overseas to camps in Canada and Australia. The journey was perilous—one ship bound for Canada was sunk by a German vessel, resulting in 714 deaths.

7 Finland Starved 4,000 Prisoners To Death

In Finland, the victims were Russian civilians. When the Finnish army advanced into East Karelia, they rounded up 24,000 Russian civilians and dumped them into barbed‑wire camps.

The captives received barely enough food, and before the war concluded, 4,000 of them had perished from starvation.

The rationale for the roundup was not security; rather, the Finns intended to trade these civilians for prisoners of war. Jewish detainees were also leveraged to curry favor with the Nazis, with more than ten percent handed over to the Gestapo.

Malnutrition proved the deadliest foe. In the middle of 1942, the camps saw a surge in deaths, with roughly 3,500 Russian prisoners starving to death over a few months.

6 The Japanese Starved And Murdered Interned Civilians

The Imperial Japanese government incarcerated more civilians than the United States did, imprisoning over 130,000 enemy aliens across the colonies they occupied.

These were ordinary civilians living in Southeast Asian territories who happened to be in the wrong place at the wrong time. Their treatment often mirrored that of military POWs.

In many camps, rations were so meager that prisoners hovered on the brink of starvation, and guards employed violent force against any perceived disobedience. One internee recalled that beatings were as regular as the ticking of a clock.

The most harrowing conditions occurred in the smallest camps, where guards acted with extreme brutality. Survivors from a Nauru camp that held only seven prisoners reported that, after an Allied bombing, the Japanese guards beheaded two of the detainees to vent their frustration.

5 Seven Prisoners In A Japanese Internment Camp Were Publicly Tortured And Executed

The largest Japanese‑run civilian camp was Stanley Internment Camp in Hong Kong, holding roughly 2,800 prisoners.

Most inmates were British civilians who refused to flee when the Japanese invaded. Their diet consisted of the remnants of leftover food; a family of five might receive a bowl of rice and a bowl of stew, both often contaminated with dust, mud, rat and cockroach excrement, cigarette ends, and even dead rats.

Out of the total population, 121 perished. The most chilling episode involved seven men who attempted an escape by using a radio to contact the outside world. When caught, they were subjected to public torture in front of the other detainees.

The torment was so severe that the men either succumbed to their injuries or were executed by shooting or beheading, serving as a stark warning to anyone considering resistance.

4 Jewish Refugees Were Robbed And Beaten On The Way To Camps In Australia

Australia interned its own Japanese, German, and Italian residents, and also accepted 8,000 foreigners, among them thousands of Jewish refugees.

The most notorious episode involved the Dunera, a British vessel originally meant for 1,600 passengers but crammed with 2,500, including 2,000 Jewish refugees who had escaped Nazi death camps.

These refugees were forced to share cramped spaces with 451 genuine POWs from Italy and Germany, placing them side‑by‑side with former SS officers who had terrorized their families.

During the 57‑day voyage, prisoners slept in piles on the deck, receiving only 30 minutes of fresh air daily. The air was so foul that inmates would press their faces against an open hatch for a breath of relief.

Upon arrival, the guards had looted all valuable belongings, discarding medicine and prayer books into the sea, leaving the refugees destitute.

3 Peru Deported Japanese Residents To American Internment Camps

Among the 2,200 Japanese civilians held in American camps, many had never set foot in the United States; they were Peruvian nationals seized and shipped abroad solely because of their ancestry.

The United States requested these deportations to increase its pool of civilian detainees for potential prisoner‑exchange negotiations with Japan.

Peru, eager to appease the United States, complied, especially after a May 1940 riot that saw 600 Japanese‑owned homes, schools, and businesses torched.

Some of the deported individuals were later exchanged for American POWs, while others were forced to live in Japan, a country foreign to them despite their heritage.

After the war, Peru barred most of these Japanese citizens from returning, sending roughly 1,000 back to Japan and leaving the rest to rebuild lives in the United States.

2 Native Alaskans Were Interned And Died At Horrifying Rates

Not all detainees hailed from enemy nations. A total of 881 Native Alaskans were confined for three and a half years, despite being fully American citizens.

The government claimed the internments were for their own protection, fearing that Alaska would become a war zone, and relocated them into camps that were, paradoxically, still situated in active combat zones.

The facilities were dilapidated—some were converted gold mines, others old canneries. Disease ran rampant, infecting virtually every inmate.

By the end of their confinement, one in ten of these Native Alaskans had perished, succumbing to starvation, freezing temperatures, or disease.

1 Norway Labeled Its Own Citizens As ‘German Whores’ And Locked Them Up

When the war finally drew to a close, some nations turned their vengeance inward. In Norway, 5,000 women were branded tyskertøser—literally “German whores”—and imprisoned without trial.

While a minority had taken German lovers during the occupation, many were merely employed in roles that supported the occupiers, such as cleaning or sewing.

The government defended the arrests as protective measures, yet mob violence also erupted: women were publicly shorn, their heads shaved, and paraded through streets while crowds cheered.

Similar reprisals occurred in France, where women accused of collaborating faced public humiliation, head‑shaving, and swastikas painted on their faces.

Men were largely spared. In Norway, 28 men who married German women faced no repercussions, whereas every woman who married a German was expelled, stripped of citizenship, and stigmatized for life.

10 horrifying WWII: A Glimpse Into the Dark

These ten stories reveal a global pattern of fear‑driven oppression, showing how ordinary civilians became victims of wartime hysteria and state‑sanctioned cruelty.

Below we dive into 10 horrifying stories of communist prisons and labor camps, each a chilling reminder of how ideology can be twisted into terror. From the infamous S‑21 facility in Cambodia to the gruesome Pitesti Experiment in Romania, these accounts expose the brutal tactics, relentless torture, and massive loss of life that defined these repressive regimes.

10 Horrifying Stories Overview

This overview sets the stage for the ten terrifying tales that follow, highlighting the systematic cruelty inflicted upon countless inmates across continents and decades.

10 21

In 1960, two Khmer men—Saloth Sar and Nuon Chea—formed a small, Mao‑inspired communist cell that would later be known as the Communist Party of Kampuchea, better recognized by its French moniker, the Khmer Rouge or “Red Khmers.” Saloth Sar eventually adopted the name Pol Pot as his own.

From 1960 until 1975, the Khmer Rouge waged a guerrilla war against the Kingdom of Cambodia, which was backed by the United States and France. Though initially supported by Ho Chi Minh’s Vietnamese communists, the alliance fractured, culminating in a full‑scale Vietnamese invasion of Cambodia in 1979.

The regime’s brutality sparked the infamous “Year Zero” policy in 1975, forcing two million city dwellers from Phnom Penh and other urban areas into forced agricultural labor. The Khmer Rouge outlawed money, markets, schooling, private ownership, religion, and many facets of traditional Khmer culture. To enforce obedience, they erected re‑education camps nationwide, the most notorious being S‑21.

When Vietnam seized Phnom Penh, the guards at S‑21 fled, abandoning a trove of photographs and letters from prisoners. Estimates suggest that about 30,000 individuals passed through S‑21, with roughly 12,000 murdered.

Former camp commander Duch, whose real name was Kaing Guek Eav, later testified before an international tribunal, detailing torture methods such as beatings with sticks, electric shocks, suffocation with plastic bags, and a crude water‑boarding technique employing a towel and water. Inmates also endured electric‑wire whippings, and female prisoners faced rape and sexual assault. Some former Khmer Rouge members admitted that while the official aim of torture was to extract confessions, it was frequently carried out for sheer personal gratification.

Between 1975 and 1979, Pol Pot’s reign resulted in the deaths of 1.5 to 2 million Cambodians. Pol Pot himself died in 1998 at the age of 72.

9 Vietnam’s Reeducation Camps

Even after ousting the genocidal Khmer Rouge, Vietnam’s communist regime cannot be labeled a humanitarian beacon. Following the North’s victorious takeover of the South in 1975, the new government instituted a network of brutal re‑education camps across the nation.

Estimates indicate that between one and 2.5 million individuals entered these camps in 1975 alone, promised swift “re‑education” in Marxist‑Leninist doctrine. The camps were stratified into five levels. Level‑one camps functioned as study centers, allowing inmates to return home each night, while level‑two camps imposed similar indoctrination but barred nightly returns for three to six months. Roughly 700,000 people endured both level‑one and level‑two programs.

Level‑three camps, termed socialist reform camps, housed about 50,000 inmates. Levels‑four and five mirrored level‑three in their harsh labor demands, targeting those deemed less receptive to socialist ideology—intellectuals, Roman Catholics, teachers, legislators, and judges. Even as late as 1987, approximately 15,000 prisoners remained incarcerated.

It is believed that as many as 165,000 Vietnamese perished in these camps between 1975 and 1990, though the true toll may be higher. Considering that the first re‑education facilities were launched in North Vietnam in 1961, it is plausible that over one million Vietnamese lost their lives in communist‑run camps across both the North and South.

8 The Xinjiang Camps

The far‑western Chinese region of Xinjiang has endured centuries of conflict. In 1775, the Qing Empire, ruled by Manchu elites, launched a campaign that exterminated between 480,000 and 500,000 Dzungar Mongols—roughly 80 % of their population—while the survivors were enslaved.

Today, the Uyghur minority faces a massive government crackdown. Roughly one million people are believed to be detained in internment facilities across China, representing about ten percent of the entire Uyghur population.

The stated aim of these camps is to “re‑educate” Uyghurs and erase their ethnic and religious identity. Inmates are forced to converse in Mandarin and are reportedly required to proclaim, “I’m not a Muslim,” each day. Similar pressures are applied to other minorities, including Hui Muslims, Kazakhs, Uzbeks, Turkmen, and even non‑Muslim groups.

In 2018, Uyghur activists told Radio Free Asia that the Xinjiang camps are squalid work sites where detainees must praise Xi Jinping daily, sing communist anthems, and publicly confess to “crimes” such as attending a mosque or traveling abroad. Former inmate Kayrat Samarkand, a Kazakh, recounted grueling interrogations lasting several days and described being forced to wear a metal suit weighing over 23 kg (50 lb) as a form of torture.

The Chinese government justifies these measures by citing Islamist terrorism within its borders and highlighting Uyghur involvement in conflicts in Syria and Afghanistan alongside ISIS and Al‑Qaeda affiliates.

7 ‘Farewell To The World’

Few outside the Ethiopian diaspora are familiar with the Derg, officially the Provisional Military Government of Socialist Ethiopia, which seized power in 1974 and ruled until 1987. During its tenure, Ethiopia endured multiple humanitarian catastrophes: a massive famine, economic collapse, and costly wars against Eritrean and Tigrayan forces. The most devastating period occurred between 1984 and 1986, when a two‑year drought triggered a famine that afflicted 5.8 million people, followed by locust and grasshopper plagues in 1986. In total, these crises claimed 1.2 million lives.

Beyond these “natural” disasters—largely the product of forced villagization and oppression—the Derg orchestrated a massive campaign of terror known as the Red Terror. Announced after the Derg seized Addis Ababa, the Red Terror saw troops and communist militias storm homes and villages in search of “counter‑revolutionaries.” Estimates suggest up to 50,000 people were killed during this purge.

Many Red Terror victims were incarcerated at Alem Bekagn, meaning “Farewell to the World,” a prison in Addis Ababa already infamous for the 1937 Yekatit 12 massacre carried out by Italian fascists. Under the Derg, Alem Bekagn became a site of torture and mass execution. Argentine forensic experts uncovered several mass graves there in 1990. One of the worst atrocities, the Massacre of Sixty, involved Derg officials executing 60 former officials of Emperor Haile Selassie’s government. Other victims included Ethiopian teenagers, suspected anti‑communists, and intellectuals. The African Union estimates that 10,000 people were executed at Alem Bekagn, with thousands more dying from overcrowding and disease.

6 Lenin’s Gulags

Many Soviet apologists claim that Vladimir Lenin, the first communist ruler of Bolshevik Russia, was not a genocidal monster like Stalin. This view overlooks how Lenin expanded the Tsarist Siberian prison system into the notorious “gulag archipelago.”

By 1920, Russia operated about 84 labor and prison camps designed to “rehabilitate” enemies of the Soviet state. By 1923, the network swelled to over 300 camps, holding roughly 70,000 inmates. As early as 1918, Leon Trotsky wrote that the Soviet regime intended to modernize Russia on the backs of slave labor, referring to inmates as “vermin” who must endure “thousands of forms and means of practical reckoning by the communes themselves.” In practice, this meant forced labor to death on railroads and factories.

Lenin’s feared secret police, the Cheka, also ran its own camps. In 1920, 100,000 Russian citizens were convicted by Cheka courts and sentenced to forced labor. The Cheka facilities were built to house only 40,000‑60,000 inmates. Across these camps, unsanitary conditions caused thousands of deaths from disease, while starvation, overwork, and executions claimed the rest. Corruption ran rampant, with career criminals given freedom to prey upon fellow prisoners.

5 The Belene Labor Camp

The Belene Labor Camp, often labeled a “concentration” camp by Western observers, evokes the same horror associated with the Nazi Holocaust. Operated intermittently from 1949 to 1989 on Belene Island in Bulgaria, the facility detained thousands of political prisoners alongside hardened criminals, whom guards encouraged to terrorize the political detainees.

During the 1950s, hundreds of inmates succumbed to malnutrition and exhaustion while forced to fell trees, harvest vegetables, and perform other grueling manual labor with scant food or water. Prisoners who broke camp rules were sometimes used as target practice or cast adrift at sea to freeze to death.

The camp officially closed in 1959 after Soviet‑directed anti‑Stalinist purges. Nonetheless, during the 1970s and 1980s, Bulgarian Muslims and ethnic Turks opposing the government’s assimilation campaigns were detained on Belene Island under squalid conditions for months or years. Earlier, in the 1950s, Christian pastors were frequently sent to the camp as “spies.” One inmate, Haralan Popov, authored a book detailing how guards attempted to convert religious prisoners to atheism, often torturing those who resisted for days on end.

4 Castro’s Concentration Camps

The term “concentration camp” first emerged on Cuba’s verdant island in the late 19th century, originally describing Spanish‑run camps for Cuban independence supporters. The United States later used the term to justify the Spanish‑American War of 1898.

Decades later, Fidel Castro’s communist regime resurrected concentration camps for the Cuban populace. Under the innocuous name Military Units to Help Production (UMAP), the government began imprisoning anyone deemed “counter‑revolutionary” in November 1965. Humiliation, torture, and rape were commonplace, and many inmates chose suicide over starvation or disease.

The purpose of these camps was to “re‑educate” Cubans in the virtues of socialism. Religious Christians, rock‑and‑roll fans, long‑haired men, and those perceived as overly Western were forced into hard labor. Homosexuals were singled out as “scum,” deemed unworthy of the same rights as heterosexuals.

Like the infamous Nazi concentration and extermination camps, the UMAP facilities displayed slogans such as “Work Will Make Men Out of You.”

3 Laogai

Laogai, roughly translating to “reform through labor,” were modeled after Soviet gulags and opened following Mao Zedong’s rise to absolute power in 1949. Though renamed, hundreds of these camps continue operating throughout China today.

Harry Wu, a survivor who spent 19 years in a Laogai camp and now runs the Laogai Museum in the United States, claims that at the height of Mao’s rule, roughly 40 million Chinese were interned. Inmates were forced to labor for endless hours under dangerous conditions, with food and water scarcely provided, prompting theft among prisoners. The camps also allegedly harvested organs from detainees, a practice alleged to persist.

Wu describes the “tiger chair,” a brutal torture device where prisoners are bound, gagged, and forced to sit on a bench with bricks placed under their legs, compelling them to endure excruciating positions for hours or days. Mao’s regime also oversaw the Great Chinese Famine (1958‑1961), which may have claimed 30 million lives, and the Cultural Revolution (1966‑1976), during which radicalized youth publicly denounced teachers and family members as “counter‑revolutionaries.” Show trials and “struggle sessions” forced confessions, leading many to be sent to labor camps or executed. Death toll estimates for this era range from 1.5 to 7.7 million.

2 Stalin’s Gulags

No communist leader eclipses Joseph Stalin in infamy. Though credited with industrializing Russia, Stalin achieved this by murdering millions via overwork, starvation, and execution. The Great Purge alone saw 20 million people killed by state forces, while forced collectivization caused additional massive fatalities. For instance, Kazakhstan’s forced collectivization (1930‑1933) resulted in a famine that killed 1.5 million, and Ukraine’s Holodomor (1932‑1933) claimed roughly three million lives, with an estimated 28,000 Ukrainians dying of starvation each day.

Stalin expanded Lenin’s gulag system to accommodate those opposed to collectivization. Criminals and gangsters were housed alongside political prisoners, with guards encouraging them to brutalize inmates. Those lacking connections endured 14‑hour workdays, performing tasks such as lumber cutting, dam ditch digging, and ore and coal mining. Prisoners subsisted on starvation diets, leading many to die from malnutrition, dehydration, exhaustion, and lung diseases caused by inhaling dust.

Survivors like Varlam Shalamov and Aleksandr Solzhenitsyn chronicled the inhuman conditions of the gulags, where murder and robbery were commonplace among starving inmates. Former guard Danzig Baldaev produced graphic sketches depicting forced feeding, gangsters urinating on beaten inmates, decapitations, insertion of soldering irons into intimate regions, and the existence of female and child sex slavery.

1 The Pitesti Experiment

Between 1949 and 1951, Romania witnessed an atrocity so grotesque it shocked even hardened Soviet officials. Known as the Pitesti Experiment, these re‑education trials unfolded inside Pitesti Prison under the direction of Ana Pauker and Eugen Turcanu. Pauker, an Orthodox‑Jewish lifelong leftist previously involved with Romania’s Social Democratic and Socialist parties, partnered with Turcanu, a former convict and ex‑member of the anti‑Semitic Iron Guard.

Together, they transformed Pitesti Prison into a laboratory aimed at forging new communists from the remnants of pre‑communist Romania. Victims included former officials of Ion Antonescu’s regime, Iron Guard members, landowners, diplomats, Orthodox and Catholic priests, intellectuals, and Jews labeled “Zionist.” These prisoners were branded “enemies of the people,” and subjected to a spectrum of torture by Turcanu, Pauker, and their subordinates.

Methods of torture were grotesque: inmates who refused to renounce Christianity were forced to partake in a “communion” of fecal matter; those who would not confess were compelled to submerge their hands in urine‑filled chamber pots; prisoners were made to spit into the mouths of suspected spies; and on Christmas, detainees were forced to mock the Nativity. Survivors recount that Turcanu especially tormented priests, baptizing them each morning with urine and feces, holding their heads inside putrid buckets nearly to the point of drowning.

The experiment’s goal was to coerce prisoners into confessing that they deserved such punishment for past anti‑communist deeds, while simultaneously eradicating any sense of individualism. Physical torture was paired with prolonged solitary confinement, often carried out by fellow inmates—typically students recruited because of their non‑communist affiliations. Prisoners were forced to eat while kneeling on the floor with hands tied behind their backs, often consuming each other’s excrement. On Easter 1950, inmates were compelled to kiss a phallus‑shaped insect‑repellent paper, and on most other days were encouraged to commit suicide—a practice that guards sometimes halted only to prolong suffering.

The experiments ceased when Gheorghe Gheorghiu‑Dej, the Romanian Communist Party’s General Secretary, successfully lobbied Stalin to purge Pauker and her supporters. Pauker was accused of Zionism and nationalist sympathies for Jewish immigration to Israel. Turcanu stood trial in 1954 and was executed by firing squad on December 17, 1954. After his death, the Party attempted to pin all crimes on Pauker and Turcanu, though contemporary scholars generally agree the party itself fostered the experiments.
