The Roman army was famous for its discipline, which was supported by severe punishments. If the soldiers showed cowardice during the battle, then after the battle the soldiers of the detachment were lined up and every tenth was executed by lot. If the sentry fell asleep at the post, he was stoned to death. Courage in the Roman army was encouraged. Those who distinguished themselves received an increased share of military booty and were awarded honorary weapons. And the one who first climbed the walls of the enemy fortress was given a wreath with an image of a battlement wall.
