4. A few, and these included nearly all the best men, supported Hanno, but, as often happens, the larger party prevailed over the better. Hannibal was sent to Spain, where he was no sooner come than he won the favour of the entire army. [2] The old soldiers thought that Hamilcar was restored to them as he had been in his youth; they beheld [p. 11]the same lively expression and piercing eye, tile¹ same cast of countenance and features. But he soon brought it to pass that his likeness to his father was the least consideration in gaining him support. [3] Never was the same nature more adaptable to things the most diverse —obedience and command. And so one could not readily have told whether he were dearer to the general or the army. [4] When any bold or difficult deed was to be done, there was no one whom Hasdrubal liked better to entrust with it, nor did any other leader inspire his men with greater confidence or daring. [5] To reckless courage in incurring dangers he united the greatest judgment when in the midst of them. No toil could exhaust his body or overcome his spirit. Of heat and cold he was equally tolerant. His consumption of meat and drink was determined by natural desire, not by pleasure. [6] His times of waking and sleeping were not marked off by day or night: [7] what time remained when his work was done he gave to sleep, which he did not court with a soft bed or stillness, but was seen repeatedly by many lying on the ground wrapped in a common soldier's cloak amongst the sentinels and outguards. His dress was in no way superior to that of his fellows, but his arms and horses were conspicuous. [8] Both of horsemen and of foot-soldiers he was undoubtedly the first —foremost to enter battle, and last to leave it when the fighting had begun. [9] These admirable qualities of the man were equalled by his monstrous vices: his cruelty was inhuman, his perfidy worse than Punic; he had no regard for truth, and none for sanctity, no fear of the gods, no reverence for an oath, no religious scruple. [10] With this endowment of [p. 13]good and evil traits he served for the space of three² years under Hasdrubal, omitting nothing that should be done or seen by one who was to become a great commander.
