Final answer:
Elie witnessed a man copulating with a young Polish girl and was later beaten for seeing this act during his imprisonment in a concentration camp.
Step-by-step explanation:
The question refers to a grim episode during the Holocaust and does not match the provided reference information. It seems to relate to the experiences of Elie Wiesel, the author of 'Night', who witnessed many horrors in the concentration camps and suffered violence for what he saw. The correct answer, based on Wiesel's account in 'Night', is that Elie was beaten for witnessing a man copulating with a young Polish girl. His experiences are a testament to the extreme brutality and dehumanization that took place in the camps.
