These discontents were fomented by Minucius, the master of the horse, who had been left in command at Larinum. Though charged by the dictator not to risk an action, he pushed his camp forward within two miles of Hannibal, gained some advantages in skirmishing with the Carthaginian foraging parties, and sent home highly coloured despatches describing his successes. Popular feeling rose to its height, and Terentius Varro became its mouthpiece. This man was a petty merchant by trade, the son of a butcher; but he had been prætor the year before, and was now candidate for the consulship. His eloquence was great; and he forced the senate to consent to a law which gave Minucius an equal command with the dictator. Fabius quietly gave up half the army to his late subordinate, and was soon repaid for his moderation. Hannibal discovered the rash character of the new commander, and drew him out to battle. Minucius would have been defeated as utterly as Flaminius at Lake Trasimene, had not the watchful Fabius come up; upon which Hannibal drew off his men and Minucius, acknowledging Fabius as his deliverer, craved his pardon and resumed his post of master of the horse. The whole army returned to its old quarters at Larinum.

[217-216 B.C.]

Thus ended the second campaign, not greatly to the satisfaction of either party. Hannibal had hoped that ere this all southern Italy would have risen like one man against Rome. He had shown himself her master in the field; wherever her soldiers had dared to meet his, they had been grievously defeated. He had shown all indulgence for Italian prisoners, though he had put to the sword all Roman citizens. But not one city had yet opened its gates to receive him. The Gauls of the north were the only people who had joined him since he crossed the Alps. The Romans, indeed, continued to suffer cruelly, and their ordinary revenues were grievously curtailed. It was agreed that a great effort must be made in the ensuing campaign; an overpowering force was to be brought against Hannibal; he was to be crushed, if not by skill, by numbers.

When the day of electing the consuls came, out of six candidates C. Terentius Varro alone obtained a sufficient number of votes in any tribe to be returned. It is difficult to ascertain the true character of this man. His vigorous eloquence had won the confidence of the people; but so much is plain, that he was no general, and his election was esteemed a public misfortune by the senate. Varro himself presided at the election of his colleague, and the senate, anxious to provide an able general, put forward L. Æmilius Paulus as a candidate. Paulus had shown his ability in his former consulship, when he concluded the Illyrian War in a single campaign. His manners were unpopular; but so earnestly did the senate represent the necessity of the case, that he was returned without opposition.

These were the consuls elected to fight Hannibal. Their four legions were to be added to the four which Fabius commanded just before; and these eight legions were raised to more than their usual complement, so that the whole army to be commanded by the consuls must, with the allied force, have amounted to at least eighty thousand foot and more than six thousand horse.

In 216, the late consuls (Atilius had succeeded Flaminius), now serving as proconsuls, moving from Larinum southwards towards Venusia, had busied themselves with forming magazines at Canusium and Cannæ; and on the plain near the latter place their camp was formed. Hannibal, as the spring advanced, exhausted his supplies; and having by this time received recruits from Cisalpine Gaul, he made a rapid movement and seized the Roman magazine at Cannæ, encamping not far from that place, on the left bank of the Aufidus. The proconsuls sent home word of this disaster, but received strict orders to continue on the defensive till the consuls arrived to take the command. Yet it was some time before this took place, certainly not till near the end of July, for the great battle, which is now to be described, was fought on the second of August,[53] and it was fought soon after the arrival of the consuls.

The consuls immediately moved the army to the neighbourhood of Hannibal, with the intention of offering battle. But when Paulus observed the open plain, he was desirous to put off an engagement, and manœuvre so as to draw the enemy into ground less favourable for the action of cavalry. Varro, however, thought otherwise; and now appeared the evil of both consuls being joined in command of the same army. It was a repetition of the arrangement which had answered so ill in the last years with Fabius and Minucius; with this additional evil, that the consuls, instead of dividing the army between them, took the command of the whole on alternate days. The consuls were, by the constitution, equal, and Varro was far too confident of success to give way to his more experienced colleague. Æmilius felt bitterly the truth of Fabius’ parting injunction: “Remember that you will have to oppose not only Hannibal, but also Varro.”

On the first day of his sole command, Varro moved the whole army to the right bank of the Aufidus, between Cannæ and the sea, so that only the river separated the Roman camp from that of the Carthaginians. Next day Æmilius fortified a smaller camp on the left side of the river, fronting Hannibal, so as to secure the passage of the river, but resolutely declined battle. On the third day, however, when morning broke, the red standard, which was the Roman signal for battle, was seen flying from Varro’s tent. The men rejoiced at this; they were weary of their long inactivity; they were confident in their numbers, and the resolution of their favourite Varro was highly applauded.

When Æmilius found that a battle must be fought on the plain of Cannæ, he did his best to support his colleague. The whole army was drawn up facing nearly south, with the right resting on the river Aufidus. The Roman cavalry, only twenty-four hundred strong, were on this right flank; the left was covered in like manner by the cavalry of the allies. Æmilius commanded on the right, Varro on the left; the centre was under the orders of Servilius and Atilius, the proconsuls. It must be especially observed that the legionaries and allied infantry were not drawn up, as usual, in an open line, but with the ranks made deep and closed up almost like the phalanx. It has been above observed how serviceable the phalanx was on plain ground; and probably the consuls imagined that by these compact masses of infantry they might offer a more complete resistance to the formidable cavalry of Hannibal.
