While Marcellus had defeated the Eastern Roman forces under the command of Yazdegerd in Italia, Constantius was circling the outpost where the Magister Militum of the east and his army were located. The defenders of the fortress had already fallen by the time Constantius arrived, and their enemies had made use of its natural defenses to catch a breather.
Upon noticing this, Constantius was forced with two options, to lie in a wait, and hope that Durio's army would abandon the fortress in pursuit of their next target. Or lay siege to the weakened stronghold and kill the man where he stood.
Ultimately, the roman legate pulled out a solid gold solidus and flipped it. Whatever side it landed on would determine how he would proceed. Though the coin fell to the floor in under a second, the duration of its drop felt like a lifetime.
