Mauthausen survivors cheer the soldiers of the Eleventh Armored Division of the U.S. Third Army one day after their actual liberation. 

The banner reads: "The Spanish Anti-Fascists Salute the Liberating Forces." According to Pierre Serge Choumoff, a survivor of Mauthausen and Gusen, this event was recreated at the request of a senior American officer.

Liberation of Nazi Camps

As Allied and Soviet troops moved across Europe against Nazi Germany, they encountered concentration camps, mass graves, and other sites of Nazi crimes. The unspeakable conditions the liberators confronted shed light on the full scope of Nazi horrors. This year, 2020, marks the 75th anniversary of the liberation of concentration camps and the end of Nazi tyranny in Europe.

Key Facts

    Soviet forces liberated Auschwitz—the largest killing center and concentration camp complex—in January 1945. The Soviets also overran the sites of the Belzec, Sobibor, and Treblinka killing centers.

  • 2

    American forces liberated concentration camps including Buchenwald, Dora-Mittelbau, Flossenbürg, Dachau, and Mauthausen.

  • 3

    British forces liberated concentration camps in northern Germany, including Neuengamme and Bergen-Belsen.

Allied Liberation 

As Allied troops moved across Europe in a series of offensives against Nazi Germany, they began to encounter tens of thousands of concentration camp prisoners. Many of these prisoners had survived forced marches into the interior of Germany from camps in occupied Poland. These prisoners were suffering from starvation and disease.

The SS evacuated most of the prisoners to concentration camps further west during the spring of 1944. In late July 1944, as Soviet forces approached Lublin, the remaining camp staff hastily abandoned Majdanek, without fully dismantling the camp. Soviet troops first arrived at Majdanek during the night of July 22–23 and captured Lublin on July 24. Captured virtually intact, Majdanek was the first major concentration camp to be liberated. Soviet officials invited journalists to inspect the camp and evidence of the horrors that had occurred there. In the summer of 1944, the Soviets also overran the sites of the Belzec, Sobibor, and Treblinka killing centers. The Germans had dismantled these camps in 1943, after most of the Jews of Poland had already been killed.

The Soviets liberated Auschwitz, the largest killing center and concentration camp, in January 1945. The Nazis had forced the majority of Auschwitz prisoners to march westward (in what would become known as "death marches"). Soviet soldiers found over six thousand emaciated prisoners alive when they entered the camp. There was abundant evidence of mass murder in Auschwitz. The retreating Germans had destroyed most of the warehouses in the camp, but in the remaining ones the Soviets found personal belongings of the victims. They discovered, for example, hundreds of thousands of men's suits, more than 800,000 women's outfits, and more than 14,000 pounds of human hair.

In the following months, the Soviets liberated additional camps in the Baltic states and in Poland. Shortly before Germany's surrender, Soviet forces liberated the Stutthof, Sachsenhausen, and Ravensbrueck concentration camps.

US forces liberated the Buchenwald concentration camp near Weimar, Germany, on April 11, 1945, a few days after the Nazis began evacuating the camp. On the day of liberation, an underground prisoner resistance organization seized control of Buchenwald to prevent atrocities by the retreating camp guards. American forces liberated more than 20,000 prisoners at Buchenwald. They also liberated Dora-Mittelbau, Flossenbürg, Dachau, and Mauthausen.

British forces liberated concentration camps in northern Germany, including Neuengamme and Bergen-Belsen. They entered the Bergen-Belsen concentration camp, near Celle, in mid-April 1945. Some 60,000 prisoners, most in critical condition because of a typhus epidemic, were found alive. More than 10,000 of them died from the effects of malnutrition or disease within a few weeks of liberation.

Impact of Liberation 

Liberators confronted unspeakable conditions in the Nazi camps, where piles of corpses lay unburied. Only after the liberation of these camps was the full scope of Nazi horrors exposed to the world. The small percentage of inmates who survived resembled skeletons because of the demands of forced labor and the lack of food, compounded by months and years of maltreatment. Many were so weak that they could hardly move. Disease remained an ever-present danger, and many of the camps had to be burned down to prevent the spread of epidemics. Survivors of the camps faced a long and difficult road to recovery.
