Notable Moment

Constantine makes a critical tactical error after defeating Licinius at Mardia by assuming his rival retreated to Byzantium. Licinius instead withdraws north, circles back, and cuts Constantine's supply lines, forcing the western emperor to negotiate despite winning two consecutive battles.
