What are 6 other main events after the train arrives at Birkenau until the Evacuation of Buna ?

There are many important events that could be pointed out,
but I would go with the following six because of their importance to the development of
the themes in the book.

1. Elie is separated from his
mother and sisters (as the men are split from the
women).

2. Elie lies about his age so he can stay with his
father.

3. Elie sees babies being thrown into a
flame.

4. Elie walks in on Idek the Kapo while he is with a
girl and receives 25 lashes with the whip.

5. Elie watches
the hanging of a boy with "an angelic face". For thirty minutes the boy writhes as a
stranger asks "Where is God now?" and Elie replies "He is hanging here on the
gallows".

6. Elie injures his foot and is sent to the
hospital to recover.
