During the winter the Romans made preparations for bringing an unusually large force into the field. The people thought that it needed only a man of energy and decision at the head of an overwhelming force to bring the war to a close. They therefore raised to the consulship C. Terentius Varro, said to have been the son of a butcher, who had been for some time regarded as the champion of the popular party. The Senate regarded this election with dismay, as Varro possessed no military experience; and they therefore persuaded the people to appoint as his colleague L. Æmilius Paullus, who had distinguished himself by the way in which he had conducted the Illyrian war during his consulship.
Hannibal remained at Geronium until late in the spring (B.C. 216), when, compelled to move by the want of provisions, he surprised the Roman magazines at Cannæ, a small town of Apulia, and established his head-quarters there until the harvest could be got in. Meanwhile the two Roman Consuls arrived at the head of an army of little less than 90,000 men. To this mighty host Hannibal gave battle in the plains on the right bank of the Aufidus, just below the town of Cannæ. We have no statement of the numbers of his army, but it is certain that it must have been greatly inferior to that of the enemy; notwithstanding which, the excellence of his cavalry, and the disciplined valor of his African and Spanish infantry, gave him the most decisive victory. The immense army of the Romans was not only defeated, but annihilated, and between forty and fifty thousand men are said to have fallen in the field, among whom was the Consul Æmilius Paullus, both the Consuls of the preceding year, the late Master of the Horse, Minucius, above eighty senators, and a multitude of the wealthy knights who composed the Roman cavalry. The other Consul, Varro, escaped with a few horsemen to Venusia, and a small band of resolute men forced their way from the Roman camp to Canusium; all the rest were killed, dispersed, or taken prisoners. Hannibal has been generally blamed for not following up his advantage at once, after so decisive a victory, by an immediate advance upon Rome itself—a measure which was strongly urged upon him by Maharbal. "Only send me on with the cavalry," said this officer, "and within five days thou shalt sup in the Capitol." Whatever may be the motives that deterred Hannibal from marching upon Rome, we can not but be surprised at his apparent inactivity after the battle. He probably expected that so brilliant a success would immediately produce a general rising among the nations of Italy, and remained for a time quietly in Apulia, until they should have had time to declare themselves. Nor were his hopes disappointed; the Hirpinians, all the Samnites (except the Pentrian tribe), and almost all the Apulians, Lucanians, and Bruttians, declared in favor of Carthage. But, though the whole of the south of Italy was thus apparently lost to the Romans, yet the effect of this insurrection was not so decisive as it would at first appear; for the Latin colonies, which still, without exception, remained faithful, gave the Romans a powerful hold upon the revolted provinces; and the Greek cities on the coast, though mostly disposed to join the Carthaginians, were restrained by the presence of Roman garrisons. Hence it became necessary to support the insurrection in the different parts of Italy with a Carthaginian force. Hannibal marched first into Samnium, and from thence into Campania, where he obtained possession of the important city of Capua, the gates of which were opened to him by the popular party. Here he established his army in winter quarters. Thus ends the first period of the war, in which Hannibal had met with uninterrupted success. Three great victories in three years, followed by the revolt of a city scarcely inferior to Rome itself in importance, seemed to promise a speedy termination of the war.
NOTE ON HANNIBAL'S PASSAGE ACROSS THE ALPS.
(See p. [84].)
The narrative in the text is taken from that of the Greek historian Polybius, which is certainly by far the most trustworthy that has descended to us; but that author has nowhere clearly stated by which of the passes across the Alps Hannibal effected his march; and this question has given rise to much controversy both in ancient and modern times. Into this discussion our limits will not allow us to enter, but the following may be briefly stated as the general results: 1. That after a careful examination of the text of Polybius, and comparison of the different localities, his narrative will be found, on the whole, to agree best with the supposition that Hannibal crossed the Graian Alps, or Little St. Bernard; though it can not be denied that there are some difficulties attending this line, especially in regard to the descent into Italy. 2. That Cælius Antipater certainly represented him as taking this route (Liv., xxi., 38); and as he is known to have followed the Greek history of Silenus, who is said to have accompanied Hannibal in many of his campaigns, his authority is of the greatest weight. 3. That Livy and Strabo, on the contrary, both suppose him to have crossed the Cottian Alps, or Mont Genèvre. But the main argument that appears to have weighed with Livy, as it has done with several modern writers on the subject, is the assumption that Hannibal descended in the first instance into the country of the Taurinians, which is opposed to the direct testimony of Polybius, who says expressly that he descended among the Insubrians, and subsequently mentions his attack on the Taurinians. 4. That, as according to Livy himself (xxi., 29), the Gaulish emissaries who acted as Hannibal's guides were Boians, it was natural that these should conduct him by the passage that led directly into the territory of their allies and brothers-in-arms, the Insubrians, rather than into that of the Taurinians, a Ligurian tribe, who were at this very time in a state of hostility with the Insubrians. And this remark will serve to explain why Hannibal chose apparently a longer route, instead of the more direct one of Mont Genèvre. Lastly, it is remarkable that Polybius, though he censures the exaggerations and absurdities with which earlier writers had encumbered their narrative, does not intimate that any doubt was entertained as to the line of march; and Pompey, in a letter to the Senate, written in 73 B.C., alludes to the route of Hannibal across the Alps as something well known. Hence it appears clear that the passage by which he crossed them must have been one of those frequented in subsequent times by the Romans. This argument seems decisive against the claims of Mont Cenis, which have been advocated by some modern writers, that pass having apparently never been used till the Middle Ages—See Dict. of Greek and Roman Biography, vol. ii., p. 334, 335.
