BATTLES OF THE TICINUS, THE TREBIA, AND LAKE TRASIMENUS.—The Romans had not the remotest idea of Hannibal's plans. With war determined upon, the Senate had sent one of the consuls, L. Sempronius Longus, with an army into Africa by the way of Sicily; while the other, Publius Cornelius Scipio, they had directed to lead another army into Spain.

While the Senate were watching the movements of these expeditions, they were startled with the intelligence that Hannibal, instead of being in Spain, had crossed the Pyrenees and was among the Gauls upon the Rhone. Sempronius was hastily recalled from his attempt upon Africa, to the defence of Italy. Scipio, on his way to Spain, had touched at Massilia, and there learned of the movements of Hannibal. He turned back, hurried into Northern Italy, and took command of the levies there. The cavalry of the two armies met upon the banks of the Ticinus, a tributary of the Po. The Romans were driven from the field by the fierce onset of the Numidian horsemen. Scipio now awaited the arrival of the other consular army, which was hurrying up through Italy by forced marches.

In the battle of the Trebia the united armies of the two consuls were almost annihilated. The Gauls, who had been waiting to see to which side fortune would incline, now flocked to the standard of Hannibal, and hailed him as their deliverer.

The spring following the victory at the Trebia, Hannibal led his army, now recruited by many Gauls, across the Apennines, and moved southward. At Lake Trasimenus he entrapped the Romans under Flaminius in a mountain defile, where, bewildered by a fog that filled the valley, the greater part of the army was slaughtered, and the consul himself was slain.

The way to Rome was now open. Believing that Hannibal would march directly upon the capital, the Senate caused the bridges that spanned the Tiber to be destroyed, and appointed Fabius Maximus dictator.

In one respect only had events disappointed Hannibal's expectations. He had thought that all the states of Italy were, like the Gauls, ready to revolt from Rome at the first opportunity that might offer itself. But not a single city had thus far proved unfaithful to her.

FABIUS "THE DELAYER."—The fate of Rome was now in the hands of Fabius. Should he risk a battle and lose it, the destiny of the capital would be sealed. He determined to adopt a more prudent policy—to follow and annoy the Carthaginian army, but to refuse all proffers of battle. Thus time might be gained for raising a new army and perfecting measures for the public defence. In every possible way Hannibal endeavored to draw his enemy into an engagement. He ravaged the fields far and wide and fired the homesteads of the Italians, in order to force Fabius to fight in their defence. The soldiers of the dictator began to murmur. They called him Cunctator, or "the Delayer." They even accused him of treachery to the cause of Rome. But nothing moved him from the steady pursuit of the policy which he clearly saw was the only prudent one to follow.

THE BATTLE OF CANNÆ.—The time gained by Fabius enabled the Romans to raise and discipline an army that might hope successfully to combat the Carthaginian forces. Early in the summer of the year 216 B.C. these new levies, numbering 80,000 men, confronted the army of Hannibal, amounting to not more than half that number, at Cannæ, in Apulia. It was the largest army the Romans had ever gathered on any battle-field. But it had been collected only to meet the most overwhelming defeat that ever befell the forces of the republic. Through the skilful manoeuvres of Hannibal, the Romans were completely surrounded, and huddled together in a helpless mass upon the field, and then for eight hours were cut down by the Numidian cavalry. From fifty to seventy thousand were slain; a few thousand were taken prisoners; only the merest handful escaped, including one of the consuls. The slaughter was so great that, according to Livy, when Mago, a brother of Hannibal, carried the news of the victory to Carthage, he, in confirmation of the intelligence, poured down in the porch of the Senate- house, nearly a peck of gold rings taken from the fingers of Roman knights.

EVENTS AFTER THE BATTLE OF CANNÆ.—The awful news flew to Rome. Consternation and despair seized the people. The city would have been emptied of its population had not the Senate ordered the gates to be closed. Never did that body display greater calmness, wisdom, prudence, and resolution. By word and act they bade the people never to despair of the republic. Little by little the panic was allayed. Measures were concerted for the defence of the capital, as it was expected that Hannibal would immediately march upon Rome. Swift horsemen were sent out along the Appian Way to gather information of the conqueror's movements, and to learn, as Livy expresses it, "if the immortal gods, out of pity to the empire, had left any remnant of the Roman name."

The leader of the Numidian cavalry, Maharbal, urged Hannibal to follow up his victory closely, "Let me advance with the cavalry," said he, "and in five days thou shalt dine in the capital." But Hannibal refused to adopt the counsel of his impetuous general. Maharbal turned away, and, with mingled reproach and impatience, exclaimed, "Alas! thou knowest how to gain a victory, but not how to use one." The great commander, while he knew he was invincible in the open field, did not think it prudent to fight the Romans behind their walls.
