Hasdrubal had commanded the Carthaginian armies in Spain for some time, with varying but generally unpropitious fortune. He had not the full authority over the Punic forces in that country which his brother and his father had previously exercised. The faction at Carthage, which was at feud with his family, succeeded in fettering and interfering with his power; and other generals were from time to time sent into Spain, whose errors and misconduct caused the reverses that Hasdrubal met with. This is expressly attested by the Greek historian Polybius, who was the intimate friend of the younger Africanus, and drew his information respecting the second Punic war from the best possible authorities. Livy gives a long narrative of campaigns between the Roman commanders in Spain and Hasdrubal, which is so palpably deformed by fictions and exaggerations as to be hardly deserving of attention. [See the excellent criticisms of Sir Walter Raleigh on this, in his "History of the World," book v. chap. iii. sec. 11.] It is clear that in the year 208 B.C., at least, Hasdrubal outmanoeuvred Publius Scipio, who held the command of the Roman forces in Spain; and whose object was to prevent him from passing the Pyrenees and marching upon Italy. Scipio expected that Hasdrubal would attempt the nearest route, along the coast of the Mediterranean; and he therefore carefully fortified and guarded the passes of the eastern Pyrenees. But Hasdrubal passed these mountains near their western extremity; and then, with a considerable force of Spanish infantry, with a small number of African troops, with some elephants and much treasure, he marched, not directly towards the coast of the Mediterranean, but in a north-eastern line towards the centre of Gaul. He halted for the winter in the territory of the Arverni, the modern Auvergne; and conciliated or purchased the good-will of the Gauls in that region so far, that he not only found friendly winter quarters among them, but great numbers of them enlisted under him, and on the approach of spring marched with him to invade Italy. By thus entering Gaul at the south-west, and avoiding its southern maritime districts, Hasdrubal kept the Romans in complete ignorance of his precise operations and movements in that country; all that they knew was that Hasdrubal had baffled Scipio's attempts to detain him in Spain; that he had crossed the Pyrenees with soldiers, elephants, and money, and that he was raising fresh forces among the Gauls. The spring was sure to bring him into Italy; and then would come the real tempest of the war, when from the north and from the south the two Carthaginian armies, each under a son of the Thunderbolt, were to gather together around the seven hills of Rome. [Hamilcar was surnamed Barca, which means the Thunderbolt. Sultan Bajazet had the similar surname of Yilderim.] In this emergency the Romans looked among themselves earnestly and anxiously for leaders fit to meet the perils of the coming campaign.
