1. Auschwitz: This was the first camp he was sent to, and it is where his life changed drastically. This camp was known for its brutality and the systematic extermination of Jews.
2. Buna: This was a subcamp of Auschwitz, located near a chemical factory. Elie and his father were forced to work there in brutal conditions.
3. Buchenwald: This was the final camp Elie was sent to, after the liberation of Auschwitz. This camp was notorious for its disease and starvation.
It is important to note that these camps were not all the same. While Auschwitz was the main camp, Buna and Buchenwald were sub-camps where prisoners were sent to work in different industries.
