The Soviet Army liberated the first concentration camp, Majdanek, in July 1944 and continued liberating other camps, including Auschwitz in January 1945. The retreating Nazis left behind emaciated survivors and attempted to destroy evidence of their crimes. Allied soldiers were horrified by the conditions in camps, finding corpses, disease, and evidence of mass murder. Many survivors were too ill to recover and died after liberation, while others struggled with immense losses and adjusting to normal life after the war.
