What happens when a workman throws bread into the wagon

Once, some German workmen begin throwing bread into the car and stand around watching as the prisoners tear each other to death for scraps. Desperate for food, the prisoners behave like wild beasts. Eliezer resolves not to fight for the food and notices one man who kills his own father for a piece of bread. Then, the son is killed for the same bread, and both father and son lie dead side by side. Eliezer notes at this point in the narrative that he is fifteen years old.
