The Battle of Pollentia was fought on 6 April 402 between the Romans under Stilicho and the Visigoths under Alaric I, during the first Gothic invasion of Italy (401–403). The Romans were victorious, and forced Alaric to retreat, though he rallied to fight again in the next year in the Battle of Verona, where he was again defeated. After this, Alaric retreated from Italy, leaving the province in peace until his second invasion in 409, after Stilicho's death.
