With these promises he so prevailed, that he raised a greater army than had ever yet been sent out of Rome. There were enlisted eighty-eight thousand fighting men; but what gave confidence to the populace, only terrified the wise and experienced, and none more than Fabius; since if so great a body, and the flower of the Roman youth, should be cut off, they could not see any new resource for the safety of Rome. They addressed themselves, therefore, to the other consul, Aemilius Paulus, a man of great experience in war, but unpopular, and fearful also of the people, who once before upon some impeachment had condemned him; so that he needed encouragement to withstand his colleague's temerity. Fabius told him, if he would profitably serve his country, he must no less oppose Varro's ignorant eagerness than Hannibal's conscious readiness, since both alike conspired to decide the fate of Rome by a battle. "It is more reasonable," he said to him, "that you should believe me than Varro, in matters relating to Hannibal, when I tell you that if for this year you abstain from fighting with him, either his army will perish of itself, or else he will be glad to depart of his own will. This evidently appears, inasmuch as, notwithstanding his victories, none of the countries or towns of Italy come in to him, and his army is not now the third part of what it was at first." To this Paulus is said to have replied, "Did I only consider myself, I should rather choose to be exposed to the weapons of Hannibal than once more to the suffrages of my fellow-citizens, who are urgent for what you disapprove; yet since the cause of Rome is at stake, I will rather seek in my conduct to please and obey Fabius than all the world besides."These good measures were defeated by the importunity of Varro; whom, when they were both come to the army, nothing would content but a separate command, that each consul should have his day; and when his turn came, he posted his army close to Hannibal, at a village called Cannae, by the river Aufidus. It was no sooner day, but he set up the scarlet coat flying over his tent, which was the signal of battle.
This boldness of the consul, and the numerousness of his army, double theirs, startled the Carthaginians; but Hannibal commanded them to their arms, and with a small train rode out to take a full prospect of the enemy as they were now forming in their ranks, from a rising ground not far distant. One of his followers, called Gisco, a Carthaginian of equal rank with himself, told him that the numbers of the enemy were astonishing; to which Hannibal replied with a serious countenance, "There is one thing, Gisco, yet more astonishing, which you take no notice of;" and when Gisco inquired what, answered, that "in all those great numbers before us, there is not one man called Gisco." This unexpected jest of their general made all the company laugh, and as they came down from the hill they told it to those whom they met, which caused a general laughter amongst them all, from which they were hardly able to recover themselves. The army, seeing Hannibal's attendants come back from viewing the enemy in such a laughing condition, concluded that it must be profound contempt of the enemy, that made their general at this moment indulge in such hilarity.
According to his usual manner, Hannibal employed stratagems to advantage himself. In the first place, he so drew up his men that the wind was at their backs, which at that time blew with a perfect storm of violence, and, sweeping over the great plains of sand, carried before it a cloud of dust over the Carthaginian army into the faces of the Romans, which much disturbed them in the fight. In the next place, all his best men he put into his wings; and in the body which was somewhat more advanced than the wings, placed the worst and the weakest of his army. He commanded those in the wings, that, when the enemy had made a thorough charge upon that middle advance body, which he knew would recoil, as not being able to withstand their shock, and when the Romans in their pursuit should be far enough engaged within the two wings, they should, both on the right and the left, charge them in the flank, and endeavour to encompass them.
This appears to have been the chief cause of the Roman loss.
Pressing upon Hannibal's front, which gave ground, they reduced the form of his army into a perfect half-moon, and gave ample opportunity to the captains of the chosen troops to charge them right and left on their flanks, and to cut off and destroy all who did not fall back before the Carthaginian wings united in their rear. To this general calamity, it is also said, that a strange mistake among the cavalry much contributed. For the horse of Aemilius receiving a hurt and throwing his master, those about him immediately alighted to aid the consul; and the Roman troops, seeing their commanders thus quitting their horses, took it for a sign that they should all dismount and charge the enemy on foot. At the sight of this, Hannibal was heard to say, "This pleases me better than if they had been delivered to me bound hand and foot." For the particulars of this engagement, we refer our reader to those authors who have written at large upon the subject.
