The majority of this army consisted of soldiers who had fought under Maxentius' father Maximian for years, and as Severus reached Rome, the majority of his army went over to Maxentius, rightful heir of their former commander, who dealt out a large amount of money. When Maximian himself finally left his retreat and returned to Rome to assume the imperial office once again and support his son, Severus with the rest of his army retreated to Ravenna. Shortly after, he surrendered to Maximian, who promised that his life would be spared.
