Siege of Tunis (Mercenary War)

During the siege of Tunis in October 238 BC a rebel army under Mathos was besieged by a Carthaginian force under Hamilcar Barca and Hannibal. A portion of the Carthaginian army, which had served in Sicily during the First Punic War, mutinied in late 241 BC in the wake of Carthage's defeat, starting the Mercenary War.
