With respect to the composition of their armies, it is observable that, though thirsting for extended empire, and though some of the leading men became generals of the highest order, the Carthaginians, as a people, were anything but personally warlike. As long as they could hire mercenaries to fight for them, they had little appetite for the irksome training, and they grudged the loss of valuable time, which military service would have entailed on themselves. As Michelet remarks, "The life of an industrious merchant, of a Carthaginian, was too precious to be risked, as long as it was possible to substitute advantageously for it that of a barbarian from Spain or Gaul. Carthage knew, and could tell to a drachma, what the life of a man of each nation came to. A Greek was worth more than a Campanian, a Campanian worth more than a Gaul or a Spaniard. When once this tariff of blood was correctly made out, Carthage began a war as a mercantile speculation. She tried to make conquests in the hope of getting new mines to work, or to open fresh markets for her exports. In one venture she could afford to spend fifty thousand mercenaries, in another, rather more. If the returns were good, there was no regret felt for the capital that had been lavished in the investment; more money got more men, and all went on well." [Histoire Romaine, vol. ii. p. 40.] Armies composed of foreign mercenaries have, in all ages, been as formidable to their employers as to the enemy against whom they were directed. We know of one occasion (between the first and second Punic wars) when Carthage was brought to the very brink of destruction by a revolt of her foreign troops. Other mutinies of the same kind must from time to time have occurred. Probably one of these was the cause of the comparative weakness of Carthage at the time of the Athenian expedition against Syracuse; so different from the energy with which she attacked Gelon half a century earlier, and Dionysius half a century later. And even when we consider her armies with reference only to their efficiency in warfare, we perceive at once the inferiority of such bands of condottieri, brought together without any common bond of origin, tactics, or cause, to the legions of Rome, which at the time of the Punic wars were raised from the very flower of a hardy agricultural population trained in the strictest discipline, habituated to victory, and animated by the most resolute patriotism. And this shows also the transcendency of the genius of Hannibal, which could form such discordant materials into a compact organized force, and inspire them with the spirit of patient discipline and loyalty to their chief; so that they were true to him in his adverse as well as in his prosperous fortunes; and throughout the chequered series of his campaigns no panic rout ever disgraced a division under his command; no mutiny, or even attempt at mutiny, was ever known in his camp; and, finally, after
