The Roman historian, through whose narrative we get our only account of this debate, says that, though these were good reasons, yet strength prevailed, as usual, over wisdom, in the decision of the question. They voted to send Hannibal, and he set out to cross the sea to Spain with a heart full of enthusiasm and joy. A great deal of curiosity and interest was felt throughout the army to see him on his arrival. The soldiers had been devotedly attached to his father, and they were all ready to transfer this attachment at once to the son, if he should prove worthy of it. It was very evident, soon after he reached the camp that he was going to prove himself thus worthy. He entered at once into the duties of his position with a degree of energy, patience, and self-denial which attracted universal attention, and made him a universal favorite. He dressed plainly; he assumed no airs; he sought for no pleasures or indulgences, nor demanded any exemption from the dangers and privations which the common soldiers had to endure. lie ate plain food, and slept, often in his military cloak, on the ground, in the midst of the soldiers on guard; and in battle he was always foremost to press forward into the contest, and the last to leave the ground when the tune came for repose. The Romans .say that, in addition to these qualities, he was inhuman and merciless when in open warfare with his foes, and cunning and treacherous in every other mode of dealing with them. It is very probable that he was so. Such traits of character were considered by soldiers in those days, as they are now, virtues in themselves, though vices in their enemies.
However this may be, Hannibal became a great and universal favorite in the army. He went on for several years increasing his military knowledge, and widening and extending his influence, when at length, one day, Hasdrubal was suddenly killed by a ferocious native of the country whom he had by some means offended. As soon as the first shock of this occurrence was over, the leaders of the army went in pursuit of Hannibal, whom they brought in triumph to the tent of Hasdrubal, and instated him at once in the supreme command, with one consent and in the midst of universal acclamations. As soon as news of this event reached Carthage, the government there confirmed the act of the army, and Hannibal thus found himself suddenly but securely invested with a very high military command. His eager and restless desire to try his strength with the Romans received a new impulse by his finding that the power was now in his hands. Still the two countries were at peace. They were bound by solemn treaties to continue so. The River lberus was the boundary which separated the dominions of the two nations from each other in Spain, the territory east of that boundary being under the Roman power, and that on the west under that of the Carthaginians; except that Saguntum, which was on the western side, was an ally of the Romans, and the Carthaginians were bound by the treaty to leave it independent and free. Hannibal could not, therefore, cross the lberus or attack Saguntum without an open infraction of the treaty. He, however, immediately began to move toward Saguntum and to attack the nations in the immediate vicinity of it. If he wished to get into a war with the Romans, this was the proper way to promote it; for, by advancing thus into the immediate vicinity of the capital of their allies, there was great probability that disputes would arise which would sooner or later end in war.
