Battle of Clastidium

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. Florus tells us that the Insubred 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.
