Hamilcar's victory with Naravas took place in 240 BC in what is now north-west Tunisia. A Carthaginian army army led by Hamilcar Barca defeated a rebel army led by Spendius and Autaritus, after 2,000 Numidian cavalry led by Naravas defected from the rebels to Carthage. Carthage was fighting a coalition of mutinous soldiers and rebellious African cities in the Mercenary War which had started in 241BC.
