Climbing painfully back the way he had come, the soldier at once went with his report to Hannibal, who instantly made up his mind what to do. He carried supplies of some sort of explosive with him—what it was we do not know—and with this he blew up the rocks in front till there was a rough pathway through the face of the precipice. Then the soldiers cleared away the stones, and after one day's hard work the oxen, bearing the few stores left, and the half-starved, weary horses, were led carefully along, and down into a lower valley, where patches of grass could be seen, green amidst the wastes of snow. Here the beasts were turned loose to find their own food, and a camp was pitched to protect them.
Still, though the path had proved wide enough for horses and oxen, it was yet far too narrow for the elephants, and it took the Numidian troops three more days to make it safe for the great creatures which had struck such terror into the hearts of the mountain tribes. But weak as they were, the skin hanging loose over their bones, they made no resistance, and soon the whole army was marching towards the friendly Gauls, in the valley of the Po.
This was how in fifteen days Hannibal made the passage of the Little St. Bernard five months after he had set out from Carthagena. But the journey had been accomplished at a fearful cost, for of the fifty thousand men whom he had led from the city there remained only eight thousand Iberians or Spaniards, twelve thousand Libyans, and six thousand cavalry, though, strange to say, not one elephant had been lost.
It was well indeed for the Carthaginians that Scipio was not awaiting them at the foot of the Alps, but was making his way northwards from Pisa to the strong fortress of Placentia on the Po.
Among the friendly Gallic tribe of the Insubres, to whom Hannibal was united by the bond of hate of Rome, the troops rested and slept, and the horses and elephants grew fat once more. The men had had no time to think of themselves during those terrible weeks, and their health had suffered from the bitter cold and the wet clothes, which were often frozen on them. To add to this, their food had been as scanty as their labour had been hard, for most of their stores lay buried under the snows of the Alps. But in the rich, well-watered plains of Italy, 'the country and the inhabitants being now less rugged,' as the historian Livy tells us, they soon recovered their strength, and besieged and took by assault the city of Turin, capital of the territory of the Taurini, who were always at war with the Gallic allies of Hannibal.
With two Roman armies so near at hand the Gauls did not dare to join him in any great numbers, though they would gladly have flocked to his standard. Rome itself was filled with consternation at the news that Hannibal, whom they had expected to fight in Spain, was really in Italy, and hastily recalled the troops intended for Carthage, which were still at the Sicilian town of Lilybæum. On receipt of the order, the general Tiberius instantly sailed with part of the men for Rome, and ordered the rest of the legions to proceed to Rimini on the Adriatic, bidding each man swear that he would reach the city by bedtime on a certain day.
If you look at the map and see the distance they had to go, you will be amazed that they kept their oaths, and arrived at Rimini in four weeks, marching daily sixteen miles.
Meanwhile Scipio was encamped in Placentia, and Hannibal, who had no time to lose in besieging such a strong position, was doing his best to tempt his enemy into the plain, where his own cavalry could have room to manœuvre. But instead of remaining in Placentia, and allowing Hannibal to wear himself out in waiting, the Roman general left the town, crossed the Po, and advanced towards the river Ticino, where he ordered his engineers to build a bridge.
