Polybius · c. 160–118 BCE (composition of the Histories; later books/fragments extend beyond this span) primary

passage 244 of 490 · BOOK I > BOOK III (82/82)

in brief
As the battle begins at Cannae, early light-armed fighting turns into close hand-to-hand combat, Iberian/Celtic forces crush Romans and chase them, then the Roman pursuit draws Libyans onto the flanks and traps the legions.

[Sidenote: Fall of Aemilius Paulus.]

+116.+ Though he had been from the first on the right wing, and had taken part in the cavalry engagement, Lucius Aemilius still survived. Determined to act up to his own exhortatory speech, and seeing that the decision of the battle rested mainly on the legionaries, riding up to the centre of the line he led the charge himself, and personally grappled with the enemy, at the same time cheering on and exhorting his soldiers to the charge. Hannibal, on the other side, did the same, for he too had taken his place on the centre from the commencement. The Numidian horse on the Carthaginian right were meanwhile charging the cavalry on the Roman left; and though, from the peculiar nature of their mode of fighting, they neither inflicted nor received much harm, they yet rendered the enemy’s horse useless by keeping them occupied, and charging them first on one side and then on another. But when Hasdrubal, after all but annihilating the cavalry by the river, came from the left to the support of the Numidians, the Roman allied cavalry, seeing his charge approaching, broke and fled. At that point Hasdrubal appears to have acted with great skill and discretion. Seeing the Numidians to be strong in numbers, and more effective and formidable to troops that had once been forced from their ground, he left the pursuit to them; while he himself hastened to the part of the field where the infantry were engaged, and brought his men up to support the Libyans. Then, by charging the Roman legions on the rear, and harassing them by hurling squadron after squadron upon them at many points at once, he raised the spirits of the Libyans, and dismayed and depressed those of the Romans. It was at this point that Lucius Aemilius fell, in the thick of the fight, covered with wounds: a man who did his duty to his country at that last hour of his life, as he had throughout its previous years, if any man ever did.[200] As long as the Romans could keep an unbroken front, to turn first in one direction and then in another to meet the assaults of the enemy, they held out; but the outer files of the circle continually falling, and the circle becoming more and more contracted, they at last were all killed on the field, and among them Marcus Atilius and Gnaeus Servilius, the Consuls of the previous year, who had shown themselves brave men and worthy of Rome in the battle. While this struggle and carnage were going on, the Numidian horse were pursuing the fugitives, most of whom they cut down or hurled from their horses; but some few escaped into Venusia, among whom was Gaius Terentius, the Consul, who thus sought a flight, as disgraceful to himself, as his conduct in office had been disastrous to his country.

+117.+ Such was the end of the battle of Cannae, in which both sides fought with the most conspicuous gallantry, the conquered no less than the conquerors. This is proved by the fact that, out of six thousand horse, only seventy escaped with Gaius Terentius to Venusia, and about three hundred of the allied cavalry to various towns in the neighbourhood. Of the infantry ten thousand were taken prisoners in fair fight, but were not actually engaged in the battle: of those who were actually engaged only about three thousand perhaps escaped to the towns of the surrounding district, all the rest died nobly, to the number of seventy thousand, the Carthaginians being on this occasion, as on previous ones, mainly indebted for their victory to their superiority in cavalry: a lesson to posterity that in actual war it is better to have half the number of infantry, and the superiority in cavalry, than to engage your enemy with an equality in both. On the side of Hannibal there fell four thousand Celts, fifteen hundred Iberians and Libyans, and about two hundred horse.

[Sidenote: Losses of the Romans.]

The ten thousand Romans who were captured had not, as I said, been engaged in the actual battle; and the reason was this. Lucius Aemilius left ten thousand infantry in his camp that, in case Hannibal should disregard the safety of his own camp, and take his whole army on to the field, they might seize the opportunity, while the battle was going on, of forcing their way in and capturing the enemy’s baggage; or if, on the other hand, Hannibal should, in view of this contingency, leave a guard in his camp, the number of the enemy in the field might thereby be diminished. These men were captured in the following circumstances. Hannibal, as a matter of fact, did leave a sufficient guard in his camp; and as soon as the battle began, the Romans, according to their instructions, assaulted and tried to take those thus left by Hannibal. At first they held their own: but just as they were beginning to waver, Hannibal, who was by this time gaining a victory all along the line, came to their relief, and routing the Romans, shut them up in their own camp; killed two thousand of them; and took all the rest prisoners. In like manner the Numidian horse brought in all those who had taken refuge in the various strongholds about the district, amounting to two thousand of the routed cavalry.

[Sidenote: The results of the battle. Defection of the allies.]

+118.+ The result of this battle, such as I have described it, had the consequences which both sides expected. For the Carthaginians by their victory were thenceforth masters of nearly the whole of the Italian coast which is called Magna Graecia. Thus the Tarentines immediately submitted; and the Arpani and some of the Campanian states invited Hannibal to come to them; and the rest were with one consent turning their eyes to the Carthaginians: who, accordingly, began now to have high hopes of being able to carry even Rome itself by assault.

[Sidenote: Fall of Lucius Postumius in Gaul. See supra, ch. 106.]

On their side the Romans, after this disaster, despaired of retaining their supremacy over the Italians, and were in the greatest alarm, believing their own lives and the existence of their city to be in danger, and every moment expecting that Hannibal would be upon them. For, as though Fortune were in league with the disasters that had already befallen them to fill up the measure of their ruin, it happened that only a few days afterwards, while the city was still in this panic, the Praetor who had been sent to Gaul fell unexpectedly into an ambush and perished, and his army was utterly annihilated by the Celts. In spite of all, however, the Senate left no means untried to save the State. It exhorted the people to fresh exertions, strengthened the city with guards, and deliberated on the crisis in a brave and manly spirit. And subsequent events made this manifest. For though the Romans were on that occasion indisputably beaten in the field, and had lost reputation for military prowess; by the peculiar excellence of their political constitution, and the prudence of their counsels, they not only recovered their supremacy over Italy, by eventually conquering the Carthaginians, but before very long became masters of the whole world.

[Sidenote: B.C. 216.]

I shall, therefore, end this book at this point, having now recounted the events in Iberia and Italy, embraced by the 140th Olympiad. When I have arrived at the same period in my history of Greece during this Olympiad, I shall then fulfil my promise of devoting a book to a formal account of the Roman constitution itself; for I think that a description of it will not only be germane to the matter of my history, but will also be of great help to practical statesmen, as well as students, either in reforming or establishing other constitutions.
