After this victory large areas of northern Italy, including the city of Milan, changed allegiance and Constantine was able to march further to the east where he routed an enemy cavalry force camped near Brescia.

[1] Following the defection of Milan to Constantine, the city of Verona became Maxentius' most important military strongpoint in the northern part of Italy.

Verona was naturally strong as it sat in a loop of the River Adige, also its fortifications formed a formidable barrier to attack.

Maxentius' most able general, the praetorian prefect Ruricius Pompeianus, had gathered a large army from the forces in the region of Venetia and concentrated it at Verona.

Constantine responded by taking the offensive, he left a portion of his army to contain the garrison of the city, and with the remainder attacked Pompeianus' reinforcements.
