Arrived at the Pyrenees, Hannibal sent home a portion of his troops; a measure which he had resolved on from the first with the view of showing to the soldiers how confident their general was of success, and of checking the feeling that his enterprise was one of those from which there is no return home. With an army of 50,000 infantry and 9000 cavalry, entirely veteran soldiers, he crossed the Pyrenees without difficulty, and then took the coast route by Narbonne and Nimes through the Celtic territory, which was opened to the army partly by the connections previously formed, partly by Carthaginian gold, partly by arms. It was not till it arrived in the end of July at the Rhone opposite Avignon, that a serious resistance appeared to await it. The consul Scipio, who on his voyage to Spain had landed at Massilia (about the end of June), had there been informed that he had come too late and that Hannibal had crossed not only the Ebro but the Pyrenees. On receiving these accounts, which appear to have first opened the eyes of the Romans to the course and the object of Hannibal, the consul had temporarily given up his expedition to Spain, and had resolved in connection with the Celtic tribes of that region, who were under the influence of the Massiliots and thereby under that of Rome, to receive the Phoenicians on the Rhone, and to obstruct their passage of the river and their march into Italy. Fortunately for Hannibal, opposite to the point at which he meant to cross, there lay at the moment only the general levy of the Celts, while the consul himself with his army of 22,000 infantry and 2000 horse was still in Massilia, four days' march farther down the stream. The messengers of the Gallic levy hastened to inform him. It was the object of Hannibal to convey his army with its numerous cavalry and elephants across the rapid stream under the eyes of the enemy, and before the arrival of Scipio; and he possessed not a single boat. Immediately by his directions all the boats belonging to the numerous navigators of the Rhone in the neighbourhood were bought up at any price, and the deficiency of boats was supplied by rafts made from felled trees; and in fact the whole numerous army could be conveyed over in one day. While this was being done, a strong division under Hanno, son of Bomilcar, proceeded by forced marches up the stream till they reached a suitable point for crossing, which they found undefended, situated two short days' march above Avignon. Here they crossed the river on hastily constructed rafts, with the view of then moving down on the left bank and taking the Gauls, who were barring the passage of the main army, in the rear. On the morning of the fifth day after they had reached the Rhone, and of the third after Hanno's departure, the smoke-signals of the division that had been detached rose up on the opposite bank and gave to Hannibal the anxiously awaited summons for the crossing.
