The Battle of Tarentum of 209 BC was a battle in the Second Punic War. The Romans, led by Quintus Fabius Maximus Verrucosus, recaptured the city of Tarentum that had betrayed them in the first Battle of Tarentum in 212 BC. This time the commander of the city, Carthalo, turned against the Carthaginians, and supported the Romans.
