How a teenage Roman commander earned the title 'the Great' in North Africa
In 81 BC, a young Pompey was sent by Sulla to crush remaining Marian resistance in Africa. Facing a massive army near Utica, he turned a rainy, indecisive day into a total rout. This swift, brutal victory not only destroyed his enemies but secured his reputation as a rising military prodigy.
Following Sulla’s return to Italy in 83 BC and his subsequent victory at the Colline Gate, the Marian faction was largely defeated. However, pockets of resistance remained. Gnaeus Domitius Ahenobarbus had gathered an army of approximately 27,000 men near Utica, supported by the Numidian prince Hiarbas. To eliminate these threats, Sulla dispatched his young son-in-law, Pompey, granting him the rank of propraetor despite his lack of prior senatorial office.
Pompey arrived in Africa with a fleet and six legions, landing at Carthage and Utica. His arrival immediately triggered the defection of 7,000 Marian troops. Domitius attempted to lure Pompey into a disadvantageous uphill attack across a ravine, but a severe rainstorm caused him to abandon the maneuver. As the Marians retreated, Pompey seized the initiative, charging across the ravine while the weather turned against his opponents. The resulting chaos led to a total Pompeian victory, with 17,000 enemy soldiers killed or captured and Domitius himself slain during the final assault on his camp.
The campaign continued as Pompey moved to restore the deposed Hiempsal to the Numidian throne, effectively neutralizing Hiarbas. Within forty days of his initial landing, Pompey had successfully pacified the region and returned to his fleet. His rapid success and ruthless efficiency, which had earlier earned him the derogatory nickname 'the teenage butcher' for his execution of Papirius Carbo in Sicily, ultimately transformed into a legendary status. His troops hailed him as 'Imperator' and bestowed upon him the cognomen 'Magnus'—the Great—inspired by his childhood hero, Alexander of Macedon.
