From: The History of Rome, by Theodor Mommsen
Translated with the sanction of the author by William Purdie Dickson
There was still work to be done in the provinces. Sardinia had been speedily wrested by Lucius Philippus from the governor of the revolutionary government Quintus Antonius (672), and Transalpine Gaul offered little or no resistance; but in Sicily, Spain, and Africa the cause of the party defeated in Italy seemed still by no means lost. Sicily was held for them by the trustworthy governor Marcus Perpenna. Quintus Sertorius had the skill to attach to himself the provincials in Hither Spain, and to form from among the Romans settled in that quarter a not inconsiderable army, which in the first instance closed the passes of the Pyrenees: in this he had given fresh proof that, wherever he was stationed, he was in his place, and amidst all the incapables of the revolution was the only man practically useful.
In Africa the governor Hadrianus, who followed out the work of revolutionizing too thoroughly and began to give liberty to the slaves, had been, on occasion of a tumult instigated by the Roman merchants of Utica, attacked in his official residence and burnt with his attendants (672); nevertheless the province adhered to the revolutionary government, and Cinna's son-in-law, the young and able Gnaeus Domitius Ahenobarbus, was invested with the supreme command there. Propagandism had even been carried from thence into the client-states, Numidia and Mauretania.
Their legitimate rulers, Hiempsal II son of Gauda, and Bogud son of Bocchus, adhered doubtless to Sulla; but with the aid of the Cinnans the former had been dethroned by the democratic pretender Hiarbas, and similar feuds agitated the Mauretanian kingdom. The consul Carbo who had fled from Italy tarried on the island Cossyra (Pantellaria) between Africa and Sicily, at a loss, apparently, whether he should flee to Egypt or should attempt to renew the struggle in one of the faithful provinces.
