Question

How did Elie again help his father when they were on the train

I threw myself on top of his body. He was cold. I slapped him. I rubbed his hands, crying: "Father! Father! Wake up. They're trying to throw you out of the carriage.." His body remained inert. The two gravediggers, seized me by the collar."
Elie continued to argue with the men and fight for the life of his father until eventually his father did open his eyes and the men wandered off looking for other bodies.
