The term "Sonderkommando" refers to special units within Nazi concentration camps during the Holocaust. These groups were primarily composed of Jewish prisoners who were forced to assist in the operation of gas chambers and the disposal of bodies. Their role was to manage the aftermath of mass executions, often under extreme duress and threat of death. Sonderkommandos were often given temporary reprieve from execution in exchange for their cooperation. Despite the horrific conditions, some members documented their experiences, providing crucial historical evidence about the atrocities committed in camps like Auschwitz and Treblinka. Their accounts serve as a vital reminder of the human cost of the Holocaust.
