In Night, how long were author Elie Wiesel and his father at Auschwitz, and where did they go after that?

Eliezer and his
father stayed in Auschwitz for three weeks before being moved to Buna. The Jews of Sighet were
taken from their homes in 1944 at the height of the Second World War. They were among the Jews
subjected to torture and genocide during the Holocaust by the German Nazis under
Hitler.

The Jews of Sighet remained oblivious to atrocities committed against
their community by the Nazis in other regions until they were deported from their home. They
faced the realities of the Holocaust after they arrived in Birkenau and experienced the horror
of the crematoria that welcomed them at the camp. Men were separated from women, and the elderly
and children were burned at the crematoria as the rest of the prisoners watched.

The prisoners did not stay long at Birkenau before being moved to Auschwitz, which
looked better than Birkenau because it had concrete structures. Life at Auschwitz was not too
tasking, and the prisoners spent most of their time resting and walking around the camp.
However, the situation did not last long because the prisoners were moved to other camps where
they worked under extreme conditions.
