Upon the liberation of concentration camps following World War II, the Allied forces discovered the nightmarish aftermath of the Holocaust. The camps in Nazi-occupied territories were rife with scenes of mass murder, suffering, and depravity. One of the most disturbing discoveries was at Bergen-Belsen, which the British Army liberated on April 15th, 1945. Again, the horrific reality of the Nazi regime was brought to light, revealing 13,000 dead bodies and 60,000 half-starved prisoners inside. British forces also discovered a small number of SS guards who tried to conceal their identities among the prisoners. Among them was Johanna Bormann, "The Weasel of Auchwitz," who became infamous for her brutality towards prisoners after the Belsen Trials. Learn more:
