[8] Some time later, while Hasdrubal was governing that part of Spain belonging to Carthage, a slave whose master he had cruelly put to death, killed him secretly in a hunting expedition. Hannibal convicted him of this crime and put him to death with dreadful tortures. Now the army proclaimed Hannibal, although still very young, yet greatly beloved by the soldiers, their general, and the Carthaginian Senate confirmed the appointment. Those of the opposite faction, who had feared the power of Hamilcar and Hasdrubal, when they learned of their death, despised Hannibal on account of his youth and prosecuted their friends and partisans with the old charges. The people took sides with the accusers, bearing a grudge against those now prosecuted, because they remembered the old severities of the times of Hamilcar and Hasdrubal, and ordered them to turn into the public treasury the large gifts that Hamilcar and Hasdrubal had bestowed upon them, as being enemy's spoils. The prosecuted parties sent messengers to Hannibal asking him to assist them, and admonished him that, if he should neglect those who were able to assist him at home, he would be thoroughly despised by his father's enemies.

[9] He had foreseen all this and he knew that the persecution of his friends was the beginning of a plot against himself. He determined that he would not endure this enmity as a perpetual menace, as his father and brother-in-law had done, nor put up forever with the fickleness of the Carthaginians, who usually repaid benefits with ingratitude. It was said also that when he was a boy he had taken an oath upon the altar, at his father's instance, that when he should arrive at man's estate he would be the implacable enemy of Rome. For these reasons he thought that, if he could involve his country in arduous and protracted undertakings and plunge it into doubts and fears, he would place his own affairs and those of his friends in a secure position. He beheld Africa, however, and the subject parts of Spain in peace. But if he could stir up a war with Rome, which he strongly desired, he thought that the Carthaginians would have enough to think about and to be afraid of, and that if he should be successful, he would reap immortal glory by gaining for his country the government of the habitable world (for when the Romans were conquered there would be no other rivals), and if he should fail, the attempt itself would bring him great renown.
