[66.] Publius then broke up his camp, and marched through the plains to the bridge over the Padus, in haste to get Scipio retires to Placentia on the right bank of the Po. his legions across before the enemy came up. He saw that the level country where he was then was favourable to the enemy with his superiority in cavalry. He was himself disabled by a wound;[182] and he decided that it was necessary to shift his quarters to a place of safety. For a time Hannibal imagined that Scipio would give him battle with his infantry also: but when he saw that he had abandoned his camp, he went in pursuit of him as far as the bridge over the Ticinus; but finding that the Hannibal crosses the Po higher up and follows Scipio to Placentia. greater part of the timbers of this bridge had been torn away, while the men who guarded the bridge were left still on his side of the river, he took them prisoners to the number of about six hundred, and being informed that the main army was far on its way, he wheeled round and again ascended the Padus in search of a spot in it which admitted of being easily bridged. After two days’ march he halted and constructed a bridge over the river by means of boats. He committed the task of bringing over the army to Hasdrubal;[183] while he himself crossed at once, and busied himself in receiving the ambassadors who arrived from the neighbouring districts. For no sooner had he gained the advantage in the cavalry engagement, than all the Celts in the vicinity hastened to fulfil their original engagement by avowing themselves his friends, supplying him with provisions, and joining the Carthaginian forces. After giving these men a cordial reception, and getting his own army across the Padus, he began to march back again down stream, with an earnest desire of giving the enemy battle. Publius, too, had crossed the river and was now encamped under the walls of the Roman colony Placentia. There he made no sign of any intention to move; for he was engaged in trying to heal his own wound and those of his men, and considered that he had a secure base of operations where he was. A two days’ march from the place where he had crossed the Padus brought Hannibal to the neighbourhood of the enemy; and on the third day he drew out his army for battle in full view of his opponents: but as no one came out to attack, he pitched his camp about fifty stades from them.

[67.] But the Celtic contingent of the Roman army, seeing that Hannibal’s prospects looked the brighter of the two, Treachery of the Gauls serving in the army of Scipio. concerted their plans for a fixed time, and waited in their several tents for the moment of carrying them out. When the men within the rampart of the camp had taken their supper and were gone to bed, the Celts let more than half the night pass, and just about the time of the morning watch armed themselves and fell upon the Romans who were quartered nearest to them; killed a considerable number, and wounded not a few; and, finally, cutting off the heads of the slain, departed with them to join the Carthaginians, to the number of two thousand infantry and nearly two hundred cavalry. They were received with great satisfaction by Hannibal; who, after addressing them encouragingly, and promising them all suitable rewards, sent them to their several cities, to declare to their compatriots what they had done, and to urge them to make alliance with him: for he knew that they would now all feel compelled to take part with him, when they learnt the treachery of which their fellow-countrymen had been guilty to the Romans. Just at the same time the Boii came in, and handed over to him the three Agrarian Commissioners, sent from Rome to divide the lands; whom, as I have already related, they had seized by a sudden act of treachery at the beginning of the war. Hannibal gratefully acknowledged their good intention, and made a formal alliance with those who came: but he handed them back their prisoners, bidding them keep them safe, in order to get back their own hostages from Rome, as they intended at first.

Publius regarded this treachery as of most serious importance; and feeling sure that the Celts in the Scipio changes his position at Placentia to one on the Trebia. neighbourhood had long been ill-disposed, and would, after this event, all incline to the Carthaginians, he made up his mind that some precaution for the future was necessary. The next night, therefore, just before the morning watch, he broke up his camp and marched for the river Trebia, and the high ground near it, feeling confidence in the protection which the strength of the position and the neighbourhood of his allies would give him.

[68.] When Hannibal was informed of Scipio’s change of quarters, he sent the Numidian horse in pursuit at once, Hannibal follows him. and the rest soon afterwards, following close behind with his main army. The Numidians, finding the Roman camp empty, stopped to set fire to it: which proved of great service to the Romans; for if they had pushed on and caught up the Roman baggage, a large number of the rear-guard would have certainly been killed by the cavalry in the open plains. But as it was, the greater part of them got across the River Trebia in time; while those who were after all too far in the rear to escape, were either killed or made prisoners by the Carthaginians.

Scipio, however, having crossed the Trebia occupied the first high ground; and having strengthened Scipio’s position on the slopes of Apennines, near the source of the Trebia. his camp with trench and palisade, waited the arrival of his colleague, Tiberius Sempronius, and his army; and was taking the greatest pains to cure his wound, because he was exceedingly anxious to take part in the coming engagement. Hannibal pitched his camp about forty stades from him. While the numerous Celts inhabiting the plains, excited by the good prospects of the Carthaginians, supplied his army with provisions in great abundance, and were eager to take their share with Hannibal in every military operation or battle.

When news of the cavalry engagement reached Rome, the disappointment of their confident expectations caused a feeling of consternation in the minds of the people. Not but that plenty of pretexts were found to prove to their own satisfaction that the affair was not a defeat. Some laid the blame on the Consul’s rashness, and others on the treacherous lukewarmness of the Celts, which they concluded from their recent revolt must have been shown by them on the field. But, after all, as the infantry was still unimpaired, they made up their minds that the general result was still as hopeful as ever. Accordingly, when Tiberius and his legions arrived at Rome, and marched through the city, they believed that his mere appearance at the seat of war would settle the matter.

His men met Tiberius at Ariminum, according to their oath, and he at once led them forward in all Tiberius Sempronius joins Scipio. haste to join Publius Scipio. The junction effected, and a camp pitched by the side of his colleague, he was naturally obliged to refresh his men after their forty days’ continuous march between Ariminum and Lilybaeum: but he went on with all preparations for a battle; and was continually in conference with Scipio, asking questions as to what had happened in the past, and discussing with him the measures to be taken in the present.

[69.] Meanwhile Hannibal got possession of Clastidium, by the treachery of a certain Brundisian, Fall of Clastidium. Hannibal’s policy towards the Italians. to whom it had been entrusted by the Romans. Having become master of the garrison and the stores of corn he used the latter for his present needs; but took the men whom he had captured with him, without doing them any harm, being desirous of showing by an example the policy he meant to pursue; that those whose present position towards Rome was merely the result of circumstances should not be terrified, and give up hope of being spared by him. The man who betrayed Clastidium to him he treated with extraordinary honour, by way of tempting all men in similar situations of authority to share the prospects of the Carthaginians. But afterwards, finding that certain Celts who lived in the fork of the Padus and the Trebia, while pretending to have made terms with him, were sending messages to the Romans at the same time, believing that they would thus secure themselves from being harmed by either side, he sent two thousand infantry with some Celtic and Numidian cavalry with orders to devastate their territory. This order being executed, and a great booty obtained, the Celts appeared at the Roman camp beseeching their aid. Tiberius had been all along looking out for an opportunity of striking a blow: A skirmish favourable to the Romans. and once seized on this pretext for sending out a party, consisting of the greater part of his cavalry; and a thousand sharp-shooters of his infantry along with them; who having speedily come up with the enemy on the other side of the Trebia, and engaged them in a sharp struggle for the possession of the booty, forced the Celts and Numidians to beat a retreat to their own camp. Those who were on duty in front of the Carthaginian camp quickly perceived what was going on, and brought some reserves to support the retreating cavalry; then the Romans in their turn were routed, and had to retreat to their camp. At this Tiberius sent out all his cavalry and sharp-shooters; whereupon the Celts again gave way, and sought the protection of their own camp. The Carthaginian general being unprepared for a general engagement, and thinking it a sound rule not to enter upon one on every casual opportunity, or except in accordance with a settled design, acted, it must be confessed, on this occasion with admirable generalship. He checked their flight when his men were near the camp, and forced them to halt and face about; but he sent out his aides and buglers to recall the rest, and prevented them from pursuing and engaging the enemy any more. So the Romans after a short halt went back, having killed a large number of the enemy, and lost very few themselves.

[70.] Excited and overjoyed at this success Tiberius was all eagerness for a general engagement. Now, it was in his power to administer the war for the present as he chose, Sempronius resolves to give battle. owing to the ill-health of Publius Scipio; yet wishing to have his colleague’s opinion in support of his own, he consulted him on this subject. Publius however took quite an opposite view of the situation. He thought his legions would be all the better for a winter under arms; and that the fidelity of the fickle Celts would never stand the test of want of success and enforced inactivity on the part of the Carthaginians: they would be certain, he thought, to turn against them once more. Besides, when he had recovered from his wound, he hoped to be able to do good service to his country himself. With these arguments he tried to dissuade Tiberius from his design. The latter felt that every one of these arguments were true and sound; but, urged on by ambition and a blind confidence in his fortune, he was eager to have the credit of the decisive action to himself, before Scipio should be able to be present at the battle, or the next Consuls arrive to take over the command; for the time for that to take place was now approaching. As therefore he selected the time for the engagement from personal considerations, rather than with a view to the actual circumstances of the case, he was bound to make a signal failure.
