LUNEBURG, Germany — The British hangman worked in silence, methodically carrying out the sentences that a military court had handed down, and by midday on December 13, 1945, eleven former guards and officials of the Bergen-Belsen concentration camp were dead, their bodies buried in unmarked graves so that no sympathizer could ever turn their resting places into shrines.
The executions at Hamelin Prison, conducted behind walls and shielded from public view, marked the final chapter of the first major British war crimes trial of the postwar era — a proceeding that had laid bare the horrors of a camp where an estimated 50,000 to 70,000 people perished and where, in the chaotic final weeks before liberation, hundreds were dying every single day.
At the center of the case stood Josef Kramer, the camp commandant whom prisoners had nicknamed “the Beast of Belsen,” and Irma Grese, a 21-year-old SS guard whose reputation for cruelty had become so notorious that even her fellow guards feared her. Both were among the eleven condemned to die by hanging.
The story of how these men and women came to face British justice began on April 15, 1945, when soldiers of the British Second Army entered Bergen-Belsen expecting to take custody of a camp whose German authorities had already agreed to surrender it peacefully. What they found instead defied military preparation and human comprehension alike.
Approximately 60,000 prisoners remained inside the wire, most of them emaciated beyond recognition, their bodies reduced to skin and bone. Some could not lift their heads from the ground. Others lay in bunks three and four to a bed, their open wounds and skeletal frames pressed together in filth that had accumulated over months of catastrophic neglect.
Scattered throughout the camp lay more than 10,000 unburied corpses. Bodies were piled atop one another in open pits, left in ditches beside latrines, and abandoned inside sleeping quarters where prisoners had simply died where they fell. Some still clutched tin cups or worn shoes.
The stench was so overwhelming that soldiers had to cover their faces to keep working.
There was no functioning sewage system, no clean water, and only a few barrels of rotting soup to feed tens of thousands. Lice and fleas had infested every surface, spreading typhus at a rate that killed between 500 and 600 people every day. Dysentery, tuberculosis, and other infections swept through the overcrowded barracks with lethal efficiency.
The camp’s so-called infirmary was a wooden hut with no medicine, no doctors, and patients lying on bare floors. British medical teams arriving from nearby field hospitals were stunned by what they encountered, but they immediately began organizing makeshift treatment areas in Hudson tents and mobile hospitals, working in protective gear because the risk of infection was so severe that some soldiers had to be quarantined after only a few hours inside the camp.
Even as medical teams fought to save the living, British officers issued direct orders to round up every person who had worked at Bergen-Belsen — SS guards, officers, administrators, doctors, cooks, and anyone else connected to the camp’s operation. Within four days of liberation, more than 80 SS staff members had been identified and arrested.
Some guards tried to deny their roles. A few swapped clothes with prisoners in desperate attempts to disappear into the crowd. Others fled into the surrounding forests, only to be caught hiding in civilian clothing or cowering in empty huts and storage areas.
Survivors were asked to identify guards who had beaten or tortured them, and many did so with devastating precision, naming names and describing specific acts of cruelty that would later form the foundation of the prosecution’s case.
British officers forced many of the captured SS guards to begin cleaning up the camp, ordering them under heavy guard to carry and bury the bodies they had allowed to rot in the open. They loaded corpses onto carts, stacked them into trenches, and covered them with lime and dirt — sometimes working for days under the watch of the very people they had once tormented.
Among the arrested was Kramer, who had commanded Bergen-Belsen since December 1944 after previous service at Auschwitz. When British officers arrived, he did not resist. He calmly walked them through the camp, showing them the buildings and even the piles of bodies, displaying neither shock nor remorse.
His composure only deepened the revulsion of the soldiers who took him into custody.
Grese was arrested wearing her SS uniform, showing no visible signs of guilt. She had patrolled the women’s sections, overseen punishments, and participated in selections, and her history of brutal treatment had earned her a reputation for cruelty that extended even among her own colleagues.
By early May 1945, it had become clear that Bergen-Belsen could not be saved. Despite round-the-clock medical efforts, strict quarantines, freshwater tanks, DDT spraying, and the isolation of sick prisoners, disease continued to spread. The wooden barracks had absorbed years of filth.
Floors were soaked with human waste. Mattresses were alive with lice. There was no safe way to rebuild or reuse any part of the original camp.
British military leaders made the decision to destroy it completely. Beginning in May 1945, soldiers used flamethrowers and fuel to burn the wooden huts one by one — sleeping quarters, storage sheds, medical huts, and watchtowers — in a controlled operation designed to prevent the fire from spreading beyond the camp perimeter. The destruction was not an act of revenge but a public health necessity, intended to stop typhus from reaching nearby German villages and British soldiers still working in the region.
Before the burning began, the last remaining survivors had already been moved to temporary hospitals and housing in nearby army barracks and emergency shelters, where they finally had clean beds, real food, and access to proper medicine. The open pits where bodies had been buried were sealed, and warning signs marked the area as contaminated. For months afterward, no one was allowed to enter without protective gear.
From that point forward, British attention shifted entirely to building a legal case. From May through August 1945, military police and war crimes investigators worked full-time interviewing hundreds of survivors now recovering in hospitals and shelters. Photographers and film crews had already documented the camp before its destruction, capturing thousands of photographs and hours of footage that would become irrefutable evidence.
Investigators also recovered documents listing prisoner names, transport lists, work rosters, and supply records, along with identification papers, military files, and orders belonging to SS guards and camp officials. These records helped connect names to faces and positions to crimes. By August, a list of 45 defendants had been assembled — 25 men and 20 women — drawn from every level of the camp’s operation.
The accused included SS officers, camp supervisors, and functionaries who had overseen roll calls, labor assignments, punishment routines, and food distribution. Some bore direct responsibility for blocks where hundreds had died from starvation or disease. Others had maintained camp security where prisoners were beaten or shot without warning.
The 20 women included female SS guards who had worked in the women’s section.
All 45 were charged under international law with war crimes and crimes against humanity — specifically mass murder, torture, forced starvation, and willful neglect of basic human needs. Importantly, the British ensured that every charge focused only on what each person had done at Bergen-Belsen. Even though some of the accused had served at Auschwitz or other camps, those crimes were excluded to keep the trial focused, simple, and tied to one clear location and time period.
On September 17, 1945, the Belsen trial opened in the town of Luneburg in a modest building quickly converted into a courtroom. It was the first major British-run war crimes trial after the end of World War II. British military judges, prosecutors, defense lawyers, and officers filled the room, alongside reporters from newspapers across Europe and America.
Most significantly, survivors of Bergen-Belsen were present, some preparing to testify publicly for the first time about what they had endured.
Each of the 45 accused sat in a long row before the judges, wearing simple clothes. Some looked nervous. Others remained expressionless.
The charges were read aloud one by one, and each defendant was told exactly what they faced and given a chance to respond.
The prosecution presented documents, photographs, and films taken immediately after liberation, along with written orders, duty rosters, and guard assignments showing who had worked where and when. But more powerful than any document were the witnesses. Survivors took the stand one after another, speaking in calm, quiet voices, sometimes pausing as memories overwhelmed them.
Many had lost their families in the camp. Others had barely survived themselves.
Some defendants tried to explain their actions. Others denied everything. A few admitted guilt.
Their lawyers argued that they had no choice, that they had no power to stop the violence. But the court kept going, reviewing each case individually over weeks of proceedings.
After more than two months of sessions, the trial ended on November 17, 1945. The court found the majority guilty. Eleven defendants were sentenced to death by hanging, including Kramer and Grese, along with SS guards who had been seen beating, shooting, or starving prisoners while on duty.
Nineteen received prison terms ranging from 10 to 15 years. Seven were acquitted because there was insufficient evidence to prove their involvement beyond a reasonable doubt.
The court emphasized that simply following orders was not a valid excuse for committing crimes against humanity. Everyone had a choice, and many of the accused had chosen to participate in cruelty even when they were not forced to do so.
The eleven condemned were transferred to Hamelin Prison, held in separate cells under round-the-clock guard to prevent suicide attempts. They were allowed no visitors and had no contact with the outside world. Each case was reviewed again by a senior military legal team to ensure all procedures had been followed correctly.
The execution date was set for December 13, 1945.
The man chosen to carry out the hangings was Albert Pierrepoint, one of Britain’s most experienced executioners, known for being fast, efficient, and professional. Preparations inside Hamelin were conducted quietly. The gallows were inspected and tested.
Ropes were measured and adjusted to match each person’s height and weight. Only a small group of trained staff and military officials were involved. No public statements were made in advance, and the press was not informed of the details.
On the morning of December 13, the executions were carried out in groups, one after another. There was no media present. The event was closed to the public.
The only people allowed inside the execution chamber were British military officers, prison staff, legal observers, and the execution team.
Each execution followed a strict procedure. The prisoner was brought from their cell at the scheduled time and quietly led to the gallows chamber, where their identity was confirmed. They were placed over the trap door.
A hood was placed over their head and the noose adjusted. Once everything was in place, Pierrepoint gave the signal, and the trap door opened. The process took only a few seconds.
The executions began in the early morning and ended around midday. Each time, the area was cleared, reset, and checked before the next prisoner was brought in. Each death was recorded officially, and the bodies were buried afterward in unmarked graves — a deliberate decision intended to prevent future supporters from treating the graves as places of respect or remembrance.
There were no funerals, no last words released to the public, and no official ceremonies.
Once the burials were completed, the case of Bergen-Belsen’s guards was officially closed. For the British government and military justice system, it was the end of a process that had begun in April with the camp’s liberation. Survivors were moved to safer places, and medical teams continued to help them recover.
Investigators stored the trial records, witness statements, and photographic evidence for historical archives.
Only days after the Belsen trial ended, the Nuremberg trials opened on November 20, 1945, in the city of Nuremberg, run by judges from the United States, Britain, the Soviet Union, and France. Unlike the Belsen trial, which focused on a single camp, Nuremberg targeted the top Nazi leaders who had created, planned, and ordered the Holocaust, the invasions, and the mass killings.
In the years that followed, many more war crimes tribunals convened. Countries including Poland, Czechoslovakia, and the Soviet Union put former SS members and collaborators on trial. Some proceedings happened quickly.
Others took decades. Bergen-Belsen’s story was taught in schools, written about in books, and used in public education to explain the horrors of the Holocaust. Film footage taken by the British was shown around the world as proof of what the Nazis had done — evidence that became critically important in later years when some attempted to deny that the Holocaust ever happened.
The legacy of the Belsen trial also shaped international law. Over time, rules were created that would be applied in later conflicts, including in Rwanda and the former Yugoslavia. The world began to understand that war crimes and crimes against humanity would not be ignored, no matter where they occurred.
Today, the original camp is gone, but the site has been turned into a memorial. Germany decided not to forget what happened there. A museum stands on the grounds, along with a cemetery for the victims and plaques telling the story of the camp.
School groups visit regularly. Survivors have returned to speak about their experiences. Historians still study the trial to understand how early justice systems handled crimes of such staggering scale.
And in Hamelin Prison, in unmarked graves whose locations were deliberately obscured, lie the remains of eleven people who learned, on a cold December morning in 1945, that the world they had helped create would not go unpunished.
