The Battle of Clastidium was fought in 222 BC between a Roman Republican army led by the Roman consul Marcus Claudius Marcellus and the Insubres, a Celtic people in northern Italy. Florus writes that the Insubres were led by Viridomarus, or Britomartus, as the name varies in translation. The Romans won the battle, and in the process, Marcellus earned the spolia opima, one of the highest honors in ancient Rome, by killing the king in single combat. It was also notable as one of the few battles won by the Roman cavalry without any aid by the legions.

Clastidium (modern Casteggio), was a village of the Ligurian tribe of Anamares (Marici named also) in Gallia Cispadana, on the Via Postumia, 5 miles east of Iria (modern Voghera) and 31 miles west of Placentia.Here in 222 BC, Marcus Claudius Marcellus defeated the Gauls and won the spolia opima; in 218 BC, Hannibal took it and its stores of grain by treachery. It never had an independent government, and not later than 190 BC was made part of the colony of Placentia, founded in 218 BC.In the Augustan division of Italy, however, Placentia belonged to the 8th region, Aemilia, whereas Iria certainly, and Clastidium possibly, belonged to the 9th region, Liguria (see Theodor Mommsen in Corp. Inscrip. Lat. vol. v. Berlin, 1877, p. 828).The remains visible at Clastidium are scanty; there is a fountain (the Fontana d'Annibale), and a Roman bridge, which seems to have been constructed of tiles, not of stone, was discovered in 1857, but destroyed.
