Final answer:
Elie Wiesel and his family were first taken to Auschwitz, an extermination camp in Eastern Europe, where victims were transported in railroad cattle-cars and misled about their fate upon arrival.
Step-by-step explanation:
The first camp that Elie Wiesel and his family were taken to was Auschwitz, an extermination camp in Eastern Europe. This camp, which started operating in early 1942, was one of several camps where Jews and other persecuted groups were brutally transported in overcrowded railroad cattle-cars. Upon arrival, victims were often misled into believing they were going to showers, only to be exposed to lethal gas chambers. Work Jews were temporarily spared to handle the grim task of the cremation of the remains before they themselves were executed.
