It would be a pity to omit so picturesque an incident as Hannibal's dream. Livy thus relates it: "He saw—so the story goes—a youth of godlike shape, who said that he had been sent by Jupiter to conduct the army of Hannibal into Italy; that he was therefore to follow, without ever turning away his eyes. At first Hannibal followed, trembling, looking neither round him nor behind; after a while, with the curiosity natural to the human mind, as he thought what that on which he was forbidden to look back might be, he could no longer restrain his eyes. What he saw was a serpent of portentous size moving onward with fearful destruction of bushes and trees; close behind the creature followed a storm-cloud with crashing thunder. He asked what this portent meant, and was told, 'It means the devastation of Italy.' He must go straight on, and leave the fates in darkness."
FOOTNOTES:
[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 enemy every opportunity of making the best of the advantage. Scipio had put some light-armed troops in the van. They seemed to have been of the poorest quality, for they fled at the first impact of the two armies. The regular cavalry of the Romans showed to better advantage. They held their own for some time against their assailants, also a force of regular cavalry. But they were at a great disadvantage. The fugitives from the front had thrown their lines into disorder. These it was impossible to keep firm when those panic-stricken creatures were trying to find their way through them. Then there happened a great misfortune. Scipio was so seriously wounded that he had to give up the command. According to the most generally received account, he was saved from capture by the valour of his son, then a lad of eighteen. We shall hear of him again, for he became in later years the great hero of the war, Scipio Africanus the elder. Some of the Roman cavalry made a determined stand round their wounded chief and contrived to carry him off the field. But the battle was lost. The defeat, however, was not so complete that the Roman camp was in any danger. Hannibal, who was still hampered by his scanty numbers, was content to rest on the field of battle. That night the Romans hurriedly retreated to Placentia, hoping to find their bridge unbroken. They had actually reached their destination before Hannibal became aware of their departure. He was in time enough, however, to capture some six hundred stragglers whom he found lingering on the left bank of the Po. A great raft had been constructed for the passage of the river, and they were at work in loosing it. Hannibal came upon them while they were so employed. He captured the men, but the raft, which it would have been a great advantage to secure, floated down-stream. Two days were spent in looking for a practicable ford. Before this could be found the Roman army had recovered its order and confidence. It suffered, however, a most damaging blow within the next few days. A body of Gallic auxiliaries, two thousand infantry, and two hundred cavalry, deserted to Hannibal, cutting down the sentries at the camp gate. The Carthaginian general gave them a hearty welcome, and held out to them great promises of advancement and reward. For the present he sent them to their homes. The best service, in his judgment, that they could do was to spread abroad the report of his generosity and of the Roman defeat.
Scipio now moved southward, falling back to a position near the river Trebia, a tributary of the Po, which flows into it on its right or southern bank. Here he fortified a camp, and sat down to await the arrival of Sempronius, his colleague in the Consulship, who had been recalled from his province (Sicily) to take part in the defence of Italy. He was suffering greatly from his wound, and was unequal to the active duties of command, which, however, he was unwilling to hand over to a substitute. Probably it would have been unconstitutional to do so, when the other Consul was within reach. Yet the prætor Manlius, in whose charge the army had originally been, was probably in the camp. Constitutional forms, as we shall see again and again, weakened the military energies of Rome. Nothing could be imagined more absurd than that the army should have been entrusted to generals, changed every year, and elected by popular vote. To oppose such men to the unequalled genius of Hannibal was to ensure defeat. The mere permanence of the Carthaginian command gave him an immense advantage. But we must never forget the other side of the case. Without these constitutional forms neither Rome nor Greece (about which the historian has to say much the same thing) could have been what they were. We must expect to find in a nation as in a man the defects of its great qualities.
Sempronius joined his colleague some time, it would seem, during the month of November. He was all for action. "It is intolerable," he urged, "that Italy should be invaded and Rome threatened in this fashion. And what are we waiting for? There is no third army that can join us. Our men will lose all heart if we let them sit in their camp while the enemy plunders our friends." All this is natural enough, especially when we know that the Romans had very little idea, so far, of what Hannibal really was. But Livy, doubtless, is right when he adds that Sempronius had before his eyes the approaching election of Consuls. On the 1st of January ensuing he would have to go out of office, and yield up his command. If he was to gain the distinction of a victory he must strike at once.
