The "Metaurus River" (now the Metauro) is a river in Italy known for the Battle of the Metaurus in 207 BC during the Second Punic War. This battle saw Roman forces decisively defeat Hannibal's brother, Hasdrubal, preventing him from reinforcing Hannibal. This victory was crucial for Rome's eventual triumph over Carthage.
