Hitherto the Carthaginian generals had scrupulously respected the territory of the Saguntines, but now that the rest of Spain was subdued it was necessary to reduce this advanced post of Rome—this open door through which Rome, now mistress of the sea, could at any moment pour her legions into the heart of Spain.

The Saguntines were not ignorant of the danger which threatened them. They had again and again sent urgently to Rome to demand that a legion should be stationed there for their protection. But Rome hesitated at despatching a legion of troops to so distant a spot, where, in case of a naval reverse, they would be isolated and cut off.

Hannibal had not far to look for an excuse for an attack upon Saguntum. On the previous year, while he had been engaged in his campaign against the Carpatans, the Saguntines, taking advantage of his critical position, had made war upon the town of Torbola, an ally of Carthage. Torbola had implored the assistance of Hannibal, and he was now preparing to march against Saguntum with his whole force without waiting for the arrival of spring. His preparations had been silently made. The Saguntines, although uneasy, had no idea of any imminent danger, and the Carthaginian army collected in and around Carthagena were in entire ignorance that they were about to be called upon to take the field.

“What say you, Malchus?” Hannibal asked that evening. “It is time now that I gave you a command. As my near relative it is fitting that you should be in authority. You have now served a campaign, and are eligible for any command that I may give you. You have shown yourself prompt in danger and worthy to command men. Which would you rather that I should place under you—a company of these giant Gauls, of the steady Iberians, of the well disciplined Libyans, or the active tribesmen of the desert? Choose which you will, and they shall be yours.”

Malchus thought for some time.

“In the day of battle,” he said at last, “I would rather lead Gauls, but, in such a march as you have told me you are meditating, I would rather have a company of Numidian footmen to act as scouts and feel the way for the army. There would not, perhaps, be so much glory to be obtained, but there would be constant work and excitement, and this will be far better than marching in the long column of the army.”

“I think your choice is a good one,” Hannibal replied. “Such a corps will be needed to feel the way as we advance, to examine the roads and indicate that by which the column had best move, and to guard against ambushes and surprises. Tomorrow I will inspect the Numidian footmen and will put them through their exercises. We will have foot races and trials of skill with the bow, and I will bid their officers pick me out two hundred of the most active and vigourous among them; these you shall have under your command. You can choose among your comrades of the guards one whom you would like to have as your lieutenant.”

“I will take Trebon,” Malchus said; “we fought side by side through the last campaign. He is prompt and active, always cheerful under fatigue, and as brave as a lion. I could not wish a better comrade.”

“So be it,” Hannibal replied, “henceforth you are captain of the advanced company of the army. Remember, Malchus, that the responsibility is a great one, and that henceforward there must be no more boyish tricks. Your company will be the eyes of the army, and upon your vigilance its safety, when we once start upon our expedition, will in no slight degree depend. Remember, too, that you have by your conduct to justify me in choosing my young kinsman for so important a post.”

The next day the Numidians were put through their exercises, and by nightfall the two hundred picked men were chosen from their ranks and were placed by Hannibal under the command of Malchus. Trebon was greatly pleased when he found himself appointed as lieutenant of the company. Although of noble family his connections were much less influential than those of the majority of his comrades, and he had deemed himself exceptionally fortunate in having been permitted to enter the chosen corps of the Carthaginian cavalry, and had not expected to be made an officer for years to come, since promotion in the Carthaginian army was almost wholly a matter of family influence.
