Documenting the Horrors of Mauthausen Concentration Camp

Documenting the horrors of Mauthausen concentration – In the final days of World War II, as Allied forces advanced across Europe, the Mauthausen concentration camp in Austria became a focal point of history’s darkest moments. Late in April 1945, three infants and their mothers were among the last to arrive at the facility, their presence a stark contrast to the grim fate awaiting many others. These women, Jewish prisoners who had survived months of brutal labor, had concealed their pregnancies from Nazi overseers. Their arrival marked a fleeting hope, but the reality they faced was no less harrowing than the suffering that preceded it.

A Liberator’s First Glimpse

Less than a week after the mothers and babies reached Mauthausen, a small American military unit—comprising roughly two dozen soldiers—freed the camp from its captors. Among them was LeRoy “Pete” Petersohn, a 22-year-old Illinois Army medic whose journey from journalism to warfare would leave an indelible mark on historical records. Petersohn’s pre-war career as a reporter equipped him with the discipline to capture the atrocities he witnessed, ensuring that the world would not soon forget them.

The liberation was a moment of both triumph and tragedy. Petersohn’s account of the scene, penned shortly after the event, reveals the visceral impact of what he saw. In a letter dated May 20, 1945, he wrote, “This is a story as I witnessed upon arriving here about two weeks ago.” His words, a blend of personal reflection and documentary rigor, would become a cornerstone of the evidence against the Nazi regime. The letter was not merely a message to his wife; it served as a testament to the camp’s devastation.

“It was a terrible sight upon arriving here,” Petersohn described. “Piles after piles of dead bodies.” He added, “The sights were horrible. The camp was almost beyond a human being to stand.”

Petersohn’s descriptions painted a picture of lifeless rows of corpses, their bodies stacked like logs, and the desperation of survivors who had been reduced to eating grass to stave off starvation. The liberators, upon opening the gates, found prisoners gasping for air, their gaunt faces etched with exhaustion and fear. Petersohn’s observations, both written and visual, were critical in preserving the truth of what had transpired within those walls.

The Weight of Proof

As the soldiers processed the camp’s horrors, they recognized the need to document everything. Petersohn and his comrades not only took photographs but also recorded footage, capturing the stark reality of the situation. These images and films, now preserved in archives, serve as enduring proof of the conditions that had plagued the camp for years. Brian Petersohn, the liberator’s son, emphasized the importance of his father’s work: “He understood that history would require proof.”

The legacy of Mauthausen’s liberation was further reinforced by the actions of General Dwight D. Eisenhower, who had ordered troops to bring civilians to the camps to witness the evidence firsthand. Petersohn’s father was part of this effort, using his skills to ensure that the world would see the truth. “He was giving testimony,” noted Lesley Stahl, a 60 Minutes correspondent who later interviewed Brian. The son nodded in agreement, underscoring the significance of his father’s contribution to the historical record.

Petersohn’s letter, sent to his wife, became a pivotal piece of evidence. It was published in a local newspaper, offering contemporaneous accounts of the liberation. The document’s emotional depth and clarity made it a powerful tool in shaping public perception of the Holocaust. As Brian reflected, “My father’s words carried the weight of what he had seen.” This was not just a personal narrative but a call to action for those who had not yet witnessed the cruelty of the Nazi system.

Survival and Sacrifice

The mothers’ survival, despite the camp’s relentless brutality, was a miracle in itself. Many prisoners had perished from disease, malnutrition, and exhaustion, but these women had managed to endure. Their pregnancies, hidden from the guards, symbolized a flicker of resilience in a place where hope was scarce. Petersohn’s account highlights their plight, noting how prisoners lay against the walls, seemingly resting, but were in fact lifeless. “My blood runs cold when I recall these sights,” he wrote, “which I witnessed.”

Their presence in the camp added a poignant layer to the liberation. The infants, born in the final months of the war, were living symbols of the camp’s enduring suffering. As the soldiers stepped into the camp, they encountered not only the dead but also the living—those who had managed to survive the unimaginable. Petersohn’s documentation of this duality, between life and death, became a testament to the resilience of the human spirit and the scale of the atrocities.

Years after his service, Brian Petersohn’s recollection of his father’s work remains vivid. When asked if he views his father as a hero, Brian hesitated. “I’m going to say yes,” he eventually replied, acknowledging the bravery of his father’s actions. “But then again, I know how humble he was—how he believed it was just what he was supposed to do. It was his job.” This humility, however, did not diminish the impact of his contributions. Petersohn’s efforts ensured that the horrors of Mauthausen would not be forgotten.

The photographs and videos taken by Petersohn and his unit are now housed in the U.S. Holocaust Memorial Museum, alongside other archival materials. These visual records, combined with personal testimonies like Petersohn’s, provide a multidimensional view of the camp’s legacy. The video above, originally published on February 15, 2026, was produced by Shari Finkelstein, Collette Richards, and Brit McCandless Farmer, and edited by April Wilson and Scott Rosann. It serves as a modern reminder of the historical significance of Petersohn’s work.

Through his documentation, Petersohn bridged the gap between the immediate experience of liberation and the long-term understanding of the Holocaust. His father’s story, preserved in letters and photographs, continues to echo through time, challenging us to remember the past and honor those who endured it. As the final days of the war gave way to a new era, the images of Mauthausen became a universal symbol of the cost of hatred and the necessity of truth.
