The Romans heard with great dismay of Hasdrubal’s departure, and they made immense exertions. Hannibal was well apprised of everything; but he expected his brother later. There is no doubt but that in the course of the preceding years he had received more reinforcements than Livy tells us; yet his old troops were indeed almost gone, and he had nothing but Italians, whom, however, he had completely under his control and command: he was therefore now obliged to carry on the war according to the Roman system. It was his endeavour, by continual marchings and counter-marchings in Apulia, Lucania, and Bruttium, to move the Romans from one place to the other, like a clever chess-player; and in this he was perfectly successful. Had Hasdrubal been like Hannibal, he would not have loitered. But he wished first to take Piacenza, which, wonderful to say, had held out until then in the midst of the Gallic tribes; for thus he would remove this thorn from the side of those Gauls, and at the same time gain a safe place of arms. In this he wasted a good deal of time in vain, which perhaps was one of the causes of his bad success. His messengers to Hannibal were intercepted, and his letters read. The Romans kept Hannibal hemmed in within three armies, none of which, however, had the courage to give battle: their main force they had sent against Gaul. Hasdrubal’s plan was to march, not through Tuscany, but along the Adriatic to the frontier of Apulia, where Hannibal was stationed. He was opposed by C. Claudius Nero as commander-in-chief; to Ariminum, M. Livius Salinator had been sent with the _volones_ and two legions of allies, six legions altogether. But Livius fell back before Hasdrubal as far as Sena Gallica, and would have retreated even to the Aternus in Picenum, had not Nero risked an expedition which is one of the boldest and most romantic ever made, but which was nevertheless successful. Hannibal was certainly not informed of the approach of his brother; this is proved beyond dispute by his march to Larinum: yet as he was not in a condition to take the Roman camp by storm, Claudius picked out the flower of his troops, and went with these by forced marches to the aid of his colleague. Hasdrubal, who had got ready to attack Livius, perceived from a careful observation of the Romans as they were turning out, that the state of their horses, arms, and accoutrements, which was quite different from what had been seen in Livius’ troops hitherto, betrayed their having made a long march; from this he concluded that the latter had received reinforcements. In the night his attention was still more aroused: he heard the trumpets and bugles blow twice, from which he inferred that there were two consuls, although the Romans had in other respects taken every care to deceive him, and had not enlarged their camps. When Hasdrubal was sure of this, he wished to go a long way round, whereas until then he had evidently advanced by the straight road along the Adriatic.
