Hannibal had long before taken the prudent precaution of acquainting himself with the nature and situation of the places through which he was to pass;[733] of sounding how the Gauls stood affected to the Romans; of winning over their chiefs, whom he knew to be very greedy of gold, by his bounty to them;[734] and of securing to himself the affection and fidelity of one part of the nations through whose country his march lay. He was not ignorant that the passage of the Alps would be attended with great difficulties; but he knew they were not unsurmountable, and that was enough for his purpose.
Hannibal began his march early in the spring, from New Carthage, where he had wintered.[735] His army then consisted of above a hundred thousand men, of which twelve thousand were cavalry, and he had near forty elephants. Having crossed the Iberus, he soon subdued the several nations which opposed him in his march; and lost a considerable part of his army in this expedition. He left Hanno to command all the country [pg 199] lying between the Iberus and the Pyrenean hills, with eleven thousand men, who were appointed to guard the baggage of those that were to follow him. He dismissed the like number, sending them back to their respective countries; thus securing to himself their affection when he should want recruits, and affording to the rest a sure hope that they should be allowed to return whenever they should desire it. He passed the Pyrenean hills, and advanced as far as the banks of the Rhone, at the head of fifty thousand foot, and nine thousand horse; a formidable army, but less so from the number than from the valour of the troops that composed it; troops who had served several years in Spain, and learned the art of war, under the ablest captains that Carthage could ever boast.
Passage of the Rhone.—Hannibal, being arrived within about four days' march from the mouth of the Rhone,[736] attempted to cross it, because the river in this place took up only the breadth of its channel.[737] He bought up all the ship-boats and little vessels he could meet with, of which the inhabitants had a great number, because of their commerce. He likewise built, with great diligence, a prodigious number of boats, little vessels, and rafts. On his arrival, he found the Gauls encamped on the opposite bank, and prepared to dispute the passage. There was no possibility of his attacking them in front. He therefore ordered a considerable detachment of his forces, under the command of Hanno, the son of Bomilcar, to pass the river higher up; and in order to conceal his march, and the design he had in view, from the enemy, he obliged them to set out in the night. All things succeeded as he had planned; and they passed the river[738] the next day without the least opposition.
They passed the rest of the day in refreshing themselves, and in the night they advanced silently towards the enemy. In the morning, when the signals agreed upon had been given, Hannibal prepared to attempt the passage. Part of his horses, completely harnessed, were put into boats, that their riders might, on landing, immediately charge the enemy. The rest [pg 200] of the horses swam over on both sides of the boats, from which one single man held the bridles of three or four. The infantry crossed the river, either on rafts, or in small boats, and in a kind of gondolas, which were only the trunks of trees, which they themselves had made hollow. The great boats were drawn up in a line at the top of the channel, in order to break the force of the waves, and facilitate the passage to the rest of the small fleet. When the Gauls saw it advancing on the river, they, according to their custom, uttered dreadful cries and howlings; and clashing their bucklers over their heads, one against the other, let fly a shower of darts. But they were prodigiously astonished, when they heard a great noise behind them, perceived their tents on fire, and saw themselves attacked both in front and rear. They now had no way left to save themselves but by flight, and accordingly retreated to their respective villages. After this, the rest of the troops crossed the river quietly, and without any opposition.
The elephants alone occasioned a great deal of trouble. They were wafted over the next day in the following manner. From the bank of the river was thrown a raft, two hundred feet in length, and fifty in breadth; this was fixed strongly to the banks by large ropes, and quite covered over with earth; so that the elephants, deceived by its appearance, thought themselves upon firm ground. From this first raft they proceeded to a second, which was built in the same form, but only a hundred feet long, and fastened to the former by chains that were easily loosened. The female elephants were put upon the first raft, and the males followed after; and when they were got upon the second raft, it was loosened from the first, and, by the help of small boats, towed to the opposite shore. After this, it was sent back to fetch those which were behind. Some fell into the water, but they at last got safe to shore, and not a single elephant was drowned.
The March after the Battle of the Rhone.—The two Roman consuls had, in the beginning of the spring, set out for their respective provinces;[739] P. Scipio for Spain with sixty ships, two Roman legions, fourteen thousand foot, and twelve hundred horse of the allies; Tiberius Sempronius for Sicily, with a [pg 201] hundred and sixty ships, two legions, sixteen thousand foot, and eighteen hundred horse of the allies. The Roman legion consisted, at that time, of four thousand foot and three hundred horse. Sempronius had made extraordinary preparations at Lilybæum, a seaport town in Sicily, with the design of crossing over directly into Africa. Scipio was equally confident that he should find Hannibal still in Spain, and make that country the seat of war. But he was greatly astonished, when, on his arrival at Marseilles, advice was brought him, that Hannibal was upon the banks of the Rhone, and preparing to cross it. He then detached three hundred horse, to view the posture of the enemy; and Hannibal detached five hundred Numidian horse for the same purpose; during which, some of his soldiers were employed in wafting over the elephants.
At the same time he gave audience, in the presence of his whole army, to one of the princes of that part of Gaul which is situated near the Po, who assured him, by an interpreter, in the name of his subjects, that his arrival was impatiently expected; that the Gauls were ready to join him, and march against the Romans, and he himself offered to conduct his army through places where they should meet with a plentiful supply of provisions. When the prince was withdrawn, Hannibal, in a speech to his troops, magnified extremely this deputation from the Gauls; extolled, with just praises, the bravery which his forces had shown hitherto; and exhorted them to sustain, to the last, their reputation and glory. The soldiers inspired with fresh ardour and courage, all at once raised their hands, and declared their readiness to follow whithersoever he should lead the way. Accordingly, he appointed the next day for his march; and, after offering up vows, and making supplications to the gods for the safety of his troops, he dismissed them; desiring, at the same time, that they would take the necessary refreshments.
Whilst this was doing, the Numidians returned. They had met with, and charged, the Roman detachment: the conflict was very obstinate, and the slaughter great, considering the small number of the combatants. A hundred and sixty of the Romans were left dead upon the spot, and more than two hundred of their enemies. But the honour of this skirmish fell to [pg 202] the Romans; the Numidians having retired and left them the field of battle. This first action was interpreted as an omen[740] of the fate of the whole war, and seemed to promise success to the Romans, but which, at the same time, would be dearly bought, and strongly contested. On both sides, those who had survived this engagement, and who had been engaged in reconnoitring, returned to inform their respective generals of what they had discovered.
Hannibal, as he had declared, decamped the next day, and crossed through the midst of Gaul, advancing northward; not that this was the shortest way to the Alps, but only, as by leading him from the sea, it prevented his meeting Scipio; and, by that means, favoured the design he had, of marching all his forces into Italy, without having weakened them by a battle.
Though Scipio marched with the utmost expedition, he did not reach the place where Hannibal had passed the Rhone, till three days after he had set out from it. Despairing therefore to overtake him, he returned to his fleet, and reimbarked, fully resolved to wait for Hannibal at the foot of the Alps. But, in order that he might not leave Spain defenceless, he sent his brother Cneius thither, with the greatest part of his army, to make head against Asdrubal; and himself set forward immediately for Genoa, with intention to oppose the army which was in Gaul, near the Po, to that of Hannibal.
