[Footnote 18: "Barca" is equivalent to the Hebrew _Barak_, and means "lightning." We may compare the surname of _Boanerges_, "Sons of Thunder," given by Christ to the sons of Zebedee. In 247 B.C. he was appointed to the chief command of the forces of Carthage, being then "a very young man," if we may so translate the term _adolescentulus_ which Livy applies to him. This word, however, is very vague. It covers any age from eighteen to upwards of thirty. Cicero, for instance, uses it of Cæsar at the age of thirty-two.] V THE AVALANCHE FROM THE ALPS A few days for rest and refreshment of the army were imperatively needed, but only a very few could be spared. Hannibal could not hope to face his antagonists without a large increase to his army, and this increase he could only get for the moment from the Gauls, the people in whose country he was, though later on reinforcements might be expected from Carthage. The Gauls would be ready enough to join him, for they were permanently hostile to Rome; but they would have to be satisfied of his strength. A war had opportunely broken out between the Taurini (Turin) and the Insubres (Milan). Hannibal took the part of the latter, and stormed a stronghold of the Taurini. From that moment he could practically command the services of as many Gauls as he wanted. But he had now to meet the Romans for the first time in the field. P. Cornelius Scipio, one of the Consuls of the year, had had the province of Spain allotted to him. His intention had been to dispute the passage of the Rhone, but Hannibal had moved with such rapidity that Scipio found himself anticipated. The Carthaginians were already across the river when Scipio reached its mouth, and had secured so long a start that it was useless to follow him. But the news of the Carthaginians arrival in Italy seemed to demand instant action. He handed his army over to Cnaeus, his brother and second-in-command, reserving for himself a few picked troops only, and sailed for Italy, where he took over the division under the charge of the prætor Manlius. He marched as rapidly as possible to Placentia (Piacenza), where he crossed the Po, and advanced up the left bank of the river till he reached the Ticinus (_Ticino_), one of its tributaries. Over this stream he threw a bridge, which he protected by building a fort. Hannibal was encamped some ten miles to the westward, at a spot called Ictumuli, and had sent out Maharbal in command of some Numidian cavalry to ravage the country; sparing, however, all the territory belonging to the Gallic tribes. Maharbal was recalled when the advance of the Romans became known, and Hannibal moved out of his camp, in personal command of his cavalry. Scipio did exactly the same. The battle that ensued was therefore wholly a battle of cavalry. This put the Romans at a great disadvantage. They were distinctly inferior in this arm, and the nature of the country, an expanse of unincumbered plain, gave the
