From: The History of Rome, by Theodor Mommsen
Translated with the sanction of the author by William Purdie Dickson
It may be doubted whether any Roman statesman of the earlier period, or of the present, can be compared in point of versatile talent to Sertorius. After Sulla's generals had compelled him to quit Spain,(15) he had led a restless life of adventure along the Spanish and African coasts, sometimes in league, sometimes at war, with the Cilician pirates who haunted these seas, and with the chieftains of the roving tribes of Libya.
15. Cf. IV. IX. Spain
The victorious Roman restoration had pursued him even thither: when he was besieging Tingis (Tangiers), a corps under Pacciaecus from Roman Africa had come to the help of the prince of the town; but Pacciaecus was totally defeated, and Tingis was taken by Sertorius. On the report of such achievements by the Roman refugee spreading abroad, the Lusitanians, who, notwithstanding their pretended submission to the Roman supremacy, practically maintained their independence, and annually fought with the governors of Further Spain, sent envoys to Sertorius in Africa, to invite him to join them, and to commit to him the command of their militia.
