What events lead to the two hangings in the story the night that Elie Wiesel describes?

The first hanging was preceded by an Allie attack, after which, a prisoner was accused and executed for stealing.

"In the name of Himmler...prisoner Number...stole during the alert...According to the law...paragraph...prisoner Number...is condemned to death. May this be a warning and an example to all prisoners"

The Oberkapo and the "pipel" were hung because they were deemed responsible when the electrical power building at Buna was blown to bits.
