From: The History of Rome, by Theodor Mommsen
Translated with the sanction of the author by William Purdie Dickson
The results still show to us, at least in a general way, what was accomplished by Hamilcar as a soldier and a statesman in the last nine years of his life (518-526)--till in the flower of his age, fighting bravely in the field of battle, he met his death like Scharn-horst just as his plans were beginning to reach maturity--and what during the next eight years (527-534) the heir of his office and of his plans, his son-in-law Hasdrubal, did to prosecute, in the spirit of the master, the work which Hamilcar had begun.
Instead of the small entrepot for trade, which, along with the protectorate over Gades, was all that Carthage had hitherto possessed on the Spanish coast, and which she had treated as a dependency of Libya, a Carthaginian kingdom was founded in Spain by the generalship of Hamilcar, and confirmed by the adroit statesmanship of Hasdrubal. The fairest regions of Spain, the southern and eastern coasts, became Phoenician provinces.
Towns were founded; above all, "Spanish Carthage" (Cartagena) was established by Hasdrubal on the only good harbour along the south coast, containing the splendid "royal castle" of its founder. Agriculture flourished, and, still more, mining in consequence of the fortunate discovery of the silver-mines of Cartagena, which a century afterwards had a yearly produce of more than 360,000 pounds (36,000,000 sesterces).
