Carthalo (d. ca. 209 BC) was an officer in Hannibal's army during the Second Punic War. He led the Numidian cavalry in a successful skirmish against Rome. After the Battle of Cannae Hannibal sent Carthalo to Rome. Carthalo's mission was to try to get Rome to consider peace. At the same time he brought a delegation of Roman prisoners in the hopes of ransoming them. The new Roman dictator, M. Iunius Pera, sent a messenger to meet the delegation and tell them to leave by nightfall.
As Fabius Maximus's force recovered Tarentum Carthalo was acting as the garrison commander. It's possible this was a different Carthalo. When winning seemed impossible Carthalo laid down his weapons and tried to find Fabuis. Carthalo had a family tie to Fabius and was hoping to use it to secure his life. Carthalo was killed before he was able to appeal to Fabius.
