It was, in fact, the plan of Scipio to come up with Hannibal and attack him as soon as possible; and, accordingly, as soon as his horsemen, or, rather, those who were left alive after the battle, had returned and informed him that Hannibal and his army were near, he put his camp in motion and moved rapidly up the river. He arrived at the place where the Carthaginians had crossed a few days after they had gone. The spot was in a terrible state of ruin and confusion. The grass and herbage were trampled down for the circuit of a mile, and all over the space were spots of black and smoldering remains, where the campfires had been kindled. The tops and branches of trees lay every where around, their leaves withering in the sun, and the groves and forests were encumbered with limbs, and rejected trunks, and trees felled and left where they lay. The shore was lined far down the stream with ruins of boats and rafts, with weapons which had been lost or abandoned, and with the bodies of those who had been drowned in the passage, or killed in the contest on the shore. These and numerous other vestiges remained but the army was gone.
There were, however, upon the ground groups of natives and other visitors, who had come to look at the spot now destined to become so memorable in history. From these men Scipio learned when and where Hannibal had gone. He decided that it was useless to attempt to pursue him. He was greatly perplexed to know what to do. In the casting of lots, Spain had fallen to him, but now that the great enemy whom he had come forth to meet had left Spain altogether, his only hope of intercepting his progress was to sail back into Italy, and meet him as he came down from the Alps into the great valley of the Po. Still, as Spain had been assigned to him as his province, he could not well entirely abandon it. He accordingly sent forward the largest part of his army into Spain, to attack the forces that Hannibal had left there, while he himself, with a smaller force, went down to the sea-shore and sailed back to Italy again. He expected to find Roman forces in the valley of the Po, with which he hoped to be strong enough to meet Hannibal as he descended from the mountains, if he should succeed in effecting a passage over them. In the mean time Hannibal went on, drawing nearer and nearer to the ranges of snowy summits which his soldiers had seen for many days in their eastern horizon. These ranges were very resplendent and grand when the sun went down in the west, for then it shone directly upon them. As the army approached nearer and nearer to them, they gradually withdrew from sight and disappeared, being concealed, by intervening summits less lofty, but nearer. As the soldiers went on however, and began to penetrate the valleys, and draw near to the awful chasms and precipices among the mountains, and saw the turbid torrents descending from them, their fears revived. It was, however, now too late to retreat. They pressed forward, ascending continually, till their road grew extremely precipitous and insecure, threading its way through almost impassable defiles, with rugged cliffs overhanging them, and snowy summits towering all around.
At last they came to a narrow defile through which they must necessarily pass, but which was guarded by large bodies of armed men assembled on the rocks and precipices above, ready to hurl stones and weapons of every kind upon them if they should attempt to pass through. The army halted. Hannibal ordered them to encamp where they were, until he could consider what to do. In the course of the day he learned that the mountaineers did not remain at their elevated posts during the night, on account of the intense cold and exposure, knowing, too, that it would be impossible for an army to traverse such a pass as they were attempting to guard without daylight to guide them, for the road, or rather pathway, which passes through these defiles, follows generally the course of a mountain torrent, which flows through a succession of frightful ravines and chasms, and often passes along on a shelf or projection of the rock, hundreds and sometimes thousands of feet from the bed of the stream, which foams and roars far below. There could, of course, be no hope of passing safely by such a route without the light of day.
The mountaineers, therefore, knowing that it was not necessary to guard the pass at night,-its own terrible danger being then a sufficient protection, were accustomed to disperse in the evening, and descend to regions where they could find shelter and repose, and to return and renew their watch in the morning. When Hannibal learned this, he determined to anticipate them in getting up upon the rocks the next day, and, in order to prevent their entertaining any suspicion of his design, he pretended to be making all the arrangements for encamping for the night on the ground he had taken. He accordingly pitched more tents, and built, toward evening, a great many fires, and he began some preparations indicating that it was his intention the next day to force his way through the pass. He moved forward a strong detachment up to a point near the entrance to the pass, and put them in a fortified position there, as if to have them all ready to advance when the proper time should arrive on the following day.
The mountaineers, seeing all these preparations going on, looked forward to a conflict on the morrow, and, during the night, left their positions as usual, to descend to places of shelter. The next morning, however, when they began, at an early hour, to ascend to them again, they were astonished to find all the lofty rocks, and cliffs, and shelving projections which overhung the pass, covered with Carthaginians.
