6. During the nine years in which Hamilcar commanded, and in the following eight in which Hasdrubal, his son-in-law and successor, was at the head of the army, the whole of the south of Spain, as far as the Iberus, was brought under subjection to Carthage, either by negotiation or force of arms. The further progress of the Carthaginians was only arrested by a treaty with the Romans, in which the Iberus was fixed upon as a frontier line, and the freedom of Saguntum acknowledged by both powers. Hasdrubal crowned his victories as a general and as a statesman by the foundation of New Carthage, (Carthagena,) which was to be the future seat of Carthaginian power in the newly-conquered country. Hasdrubal having fallen by the hand of an assassin in the year 221, the party of the Barcas succeeded in appointing Hamilcar's son, Hannibal, a young man of one-and-twenty, for his successor. Hannibal found every thing already prepared in Spain for the furtherance of the hereditary project of his family, which was a renewal of the contest with Rome; and the vigour with which this project was pursued, clearly proves how great must have been the preponderance of the Barcine influence, at that time, in Carthage. Had the commonwealth attended to the marine with the same ardour as their great general did to the land service, the fate of Rome would perhaps have been very different. Second war with Rome, 218-201, (seventeen years,) first in Italy and Spain, afterwards, from 203, in Africa itself. (See the history of this war below, in the Roman history, Book V, Period ii, parag. 6 sqq.) 7. Until Africa became the scene of action, the second war cost the republic much less than the first; the expenses being principally defrayed by Spain and Italy. Hanno, however, was at the head of a powerful party at home, who were clamorous for peace, and who can say they were wrong? As might be expected, the family of the Barcas were for war, and their influence carried the day. That general who, with hardly any support from Carthage, was yet able to maintain a footing in the country of his powerful foes for no less than fifteen years, and that, too, as much by policy as by force of arms, must extort our admiration. It cannot, however, be denied, that during the struggle one favourable opportunity, at least, was let slip of making peace; a fatal omission, for which the hero of Cannae paid dearly enough, by the failure of his darling project.
