This force, joined by 6,000 Numidian cavalry led by two disgruntled Numidian leaders, attempted to deter Masinissa's aggression against the Carthaginian-held town of Oroscopa. Amid considerable fighting Masinissa lured the Carthaginians into an area of rough terrain with limited water sources, where foraging for food was difficult, and surrounded them. The Carthaginians considered their opponents to be unregimented tribesmen and expected them to disperse, but Masinissa had forged a well-disciplined army with an efficient logistics system and it was able to starve the Carthaginians into surrender.
