On the day after the battle Nero started, and after scarcely fourteen days' absence once more confronted Hannibal in Apulia, whom no message had reached, and who had not stirred. The consul brought the message with him; it was the head of Hannibal's brother, which the Roman ordered to be thrown into the enemy's outposts, repaying in this way his great antagonist, who scorned to war with the dead, for the honourable burial which he had given to Paullus, Gracchus, and Marcellus. Hannibal saw that his hopes had been in vain, and that all was over. He abandoned Apulia and Lucania, even Metapontum, and retired with his troops to the land of the Bruttians, whose ports formed his only means of withdrawal from Italy. By the energy of the Roman generals, and still more by a conjuncture of unexampled good fortune, a peril was averted from Rome, the greatness of which justified Hannibal's tenacious perseverance in Italy, and which fully bears comparison with the magnitude of the peril of Cannae. The joy in Rome was boundless; business was resumed as in time of peace; every one felt that the danger of the war was surmounted.

Nevertheless the Romans were in no hurry to terminate the war. The state and the citizens were exhausted by the excessive moral and material strain on their energies; men gladly abandoned themselves to carelessness and repose.

The army and fleet were reduced; the Roman and Latin farmers were brought back to their desolate homesteads the exchequer was filled by the sale of a portion of the Campanian domains. The administration of the state was regulated anew and the disorders which had prevailed were done away; the repayment of the voluntary war-loan was begun, and the Latin communities that remained in arrears were compelled to fulfil their neglected obligations with heavy interest.

The war in Italy made no progress. It forms a brilliant proof of the strategic talent of Hannibal as well as of the incapacity of the Roman generals now opposed to him, that after this he was still able for four years to keep the field in the Bruttian country, and that all the superiority of his opponents could not compel him either to shut himself up in fortresses or to embark. It is true that he was obliged to retire farther and farther, not so much in consequence of the indecisive engagements which took place with the Romans, as because his Bruttian allies were always becoming more troublesome, and at last he could only reckon on the towns which his army garrisoned. Thus he voluntarily abandoned Thurii; Locri was, on the suggestion of Publius Scipio, recaptured by an expedition from Rhegium (549). As if at last his projects were to receive a brilliant justification at the hands of the very Carthaginian authorities who had thwarted him in them, these now, in their apprehension as to the anticipated landing of the Romans, revived of their own accord those plans (548, 549), and sent reinforcements and subsidies to Hannibal in Italy, and to Mago in Spain, with orders to rekindle the war in Italy so as to achieve some further respite for the trembling possessors of the Libyan country houses and the shops of Carthage. An embassy was likewise sent to Macedonia, to induce Philip to renew the alliance and to land in Italy (549). But it was too late. Philip had made peace with Rome some months before; the impending political annihilation of Carthage was far from agreeable to him, but he took no step openly at least against Rome. A small Macedonian corps went to Africa, the expenses of which, according to the assertion of the Romans, were defrayed by Philip from his own pocket; this may have been the case, but the Romans had at any rate no proof of it, as the subsequent course of events showed. No Macedonian landing in Italy was thought of.

Mago, the youngest son of Hamilcar, set himself to his task more earnestly. With the remains of the Spanish army, which he had conducted in the first instance to Minorca, he landed in 549 at Genoa, destroyed the city, and summoned the Ligurians and Gauls to arms. Gold and the novelty of the enterprise led them now, as always, to come to him in troops; he had formed connections even throughout Etruria, where political prosecutions never ceased. But the troops which he had brought with him were too few for a serious enterprise against Italy proper; and Hannibal likewise was much too weak, and his influence in Lower Italy had fallen much too low, to permit him to advance with any prospect of success. The rulers of Carthage had not been willing to save their native country, when its salvation was possible; now, when they were willing, it was possible no longer.

Nobody probably in the Roman senate doubted either that the war on the part of Carthage against Rome was at an end, or that the war on the part of Rome against Carthage must now be begun; but unavoidable as was the expedition to Africa, they were afraid to enter on its preparation. They required for it, above all, an able and beloved leader; and they had none. Their best generals had either fallen in the field of battle, or they were, like Quintus Fabius and Quintus Fulvius, too old for such an entirely new and probably tedious war. The victors of Sena, Gaius Nero and Marcus Livius, would perhaps have been equal to the task, but they were both in the highest degree unpopular aristocrats; it was doubtful whether they would succeed in procuring the command - matters had already reached such a pass that ability, as such, determined the popular choice only in times of grave anxiety - and it was more than doubtful whether these were the men to stimulate the exhausted people to fresh exertions. At length Publius Scipio returned from Spain, and the favourite of the multitude, who had so brilliantly fulfilled, or at any rate seemed to have fulfilled, the task with which it had entrusted him, was immediately chosen consul for the next year. He entered on office (549) with the firm determination of now realizing that African expedition which he had projected in Spain. In the senate, however, not only was the party favourable to a methodical conduct of the war unwilling to entertain the project of an African expedition so long as Hannibal remained in Italy, but the majority was by no means favourably disposed towards the young general himself. His Greek refinement and his modern culture and tone of thought were but little agreeable to the austere and somewhat boorish fathers of the city; and serious doubts existed both as to his conduct of the Spanish war and as to his military discipline. How much ground there was for the objection that he showed too great indulgence towards his officers of division, was very soon demonstrated by the disgraceful proceedings of Gaius Pleminius at Locri, the blame of which certainly was indirectly chargeable to the scandalous negligence which marked Scipio's supervision. In the proceedings in the senate regarding the organization of the African expedition and the appointment of a general for it, the new consul, wherever usage or the constitution came into conflict with his private views, showed no great reluctance to set such obstacles aside, and very clearly indicated that in case of need he was disposed to rely for support against the governing board on his fame and his popularity with the people. These things could not but annoy the senate and awaken, moreover, serious apprehension as to whether, in the impending decisive war and the eventual negotiations for peace with Carthage, such a general would hold himself bound by the instructions which he received - an apprehension which his arbitrary management of the Spanish expedition was by no means fitted to allay. Both sides, however, displayed wisdom enough not to push matters too far. The senate itself could not fail to see that the African expedition was necessary, and that it was not wise indefinitely to postpone it; it could not fail to see that Scipio was an extremely able officer and so far well adapted to be the leader in such a war, and that he, if any one, could prevail on the people to protract his command as long as was necessary and to put forth their last energies. The majority came to the resolution not to refuse to Scipio the desired commission, after he had previously observed, at least in form, the respect due to the supreme governing board and had submitted himself beforehand to the decree of the senate. Scipio was to proceed this year to Sicily to superintend the building of the fleet, the preparation of siege materials, and the formation of the expeditionary army, and then in the following year to land in Africa. For this purpose the army of Sicily - still composed of those two legions that were formed from the remnant of the army of Cannae - was placed at his disposal, because a weak garrison and the fleet were quite sufficient for the protection of the island; and he was permitted moreover to raise volunteers in Italy. It was evident that the senate did not appoint the expedition, but merely allowed it: Scipio did not obtain half the resources which had formerly been placed at the command of Regulus, and he got that very corps which for years had been subjected by the senate to intentional degradation. The African army was, in the view of the majority of the senate, a forlorn hope of disrated companies and volunteers, the loss of whom in any event the state had no great occasion to regret.
