[1] Ιn 268, the Alamanni, who had been making incursions into Roman territory since the reign of Marcus Aurelius, had broken through the Roman frontier at the Danube and crossed the Alps.

The power struggles in Mediolanum due to Aureolus' revolt, the murder of Emperor Gallienus and the resulting confrontation between Aureolus and Claudius, who had been nominated as emperor by Gallienus on his death bed, forced the Romans to denude the frontier of troops.

[2] Claudius returned to Rome after the battle to attend to affairs of state.
