The Senate encouraged reconciliation between Hanno and Hamilcar, and they agreed to serve together. Meanwhile, Matho and his army had left Tunis and marched south to the wealthy city of Leptis Parva, which had risen against Carthage earlier in the war. Hanno and Hamilcar marched after them with an army totalling perhaps 40,000 including every Carthaginian citizen of military age. The rebels, rather than wait to be besieged, met the Carthaginians in open battle in mid-to-late 238 BC. No details of the battle survive, but the remaining 30,000 rebels were wiped out and Matho captured with few losses to the Carthaginians. Any other prisoners were crucified, while Matho was dragged through the streets of Carthage and tortured to death by its inhabitants. Most of the towns and cities which had not already come to terms with Carthage now did so, with the exceptions of Utica and Hippo, whose inhabitants feared vengeance for their massacre of Carthaginians. They attempted to hold out, but Polybius says that they too "quickly" surrendered, probably in late 238 or very early 237 BC. The surrendered towns and cities were treated leniently, although Carthaginian governors were imposed on them.
