In a sally he even repulsed Hannibal in person with considerable loss; a success which, as the first defeat sustained by Hannibal, was of far more importance from its moral effect than from its material results. In Campania indeed, Nuceria, Acerrae, and, after an obstinate siege prolonged into the following year (539), Casilinum also, the key of the Volturnus, were conquered by Hannibal, and the severest punishments were inflicted on the senates of these towns which had adhered to Rome. But terror is a bad weapon of proselytism; the Romans succeeded, with comparatively trifling loss, in surmounting the perilous moment of their first weakness. The war in Campania came to a standstill; then winter came on, and Hannibal took up his quarters in Capua, the luxury of which was by no means fraught with benefit to his troops who for three years had not been under a roof. In the next year (539) the war acquired another aspect. The tried general Marcus Marcellus, Tiberius Sempronius Gracchus who had distinguished himself in the campaign of the previous year as master of the horse to the dictator, and the veteran Quintus Fabius Maximus, took - Marcellus as proconsul, the two others as consuls - the command of the three Roman armies which were destined to surround Capua and Hannibal; Marcellus resting on Nola and Suessula, Maximus taking a position on the right bank of the Volturnus near Cales, and Gracchus on the coast near Liternum, covering Neapolis and Cumae. The Campanians, who marched to Hamae three miles from Cumae with a view to surprise the Cumaeans, were thoroughly defeated by Gracchus; Hannibal, who had appeared before Cumae to wipe out the stain, was himself worsted in a combat, and when the pitched battle offered by him was declined, retreated in ill humour to Capua. While the Romans in Campania thus not only maintained what they possessed, but also recovered Compulteria and other smaller places, loud complaints were heard from the eastern allies of Hannibal. A Roman army under the praetor Marcus Valerius had taken position at Luceria, partly that it might, in connection with the Roman fleet, watch the east coast and the movements of the Macedonians; partly that it might, in connection with the army of Nola, levy contributions on the revolted Samnites, Lucanians, and Hirpini. To give relief to these, Hannibal turned first against his most active opponent, Marcus Marcellus; but the latter achieved under the walls of Nola no inconsiderable victory over the Phoenician army, and it was obliged to depart, without having cleared off the stain, from Campania for Arpi, in order at length to check the progress of the enemy's army in Apulia. Tiberius Gracchus followed it with his corps, while the two other Roman armies in Campania made arrangements to proceed next spring to the attack of Capua.

The clear vision of Hannibal had not been dazzled by his victories. It became every day more evident that he was not thus gaining his object Those rapid marches, that adventurous shifting of the war to and fro, to which Hannibal was mainly indebted for his successes, were at an end; the enemy had become wiser; further enterprises were rendered almost impossible by the inevitable necessity of defending what had been gained. The offensive was not to be thought of; the defensive was difficult, and threatened every year to become more so. He could not conceal from himself that the second half of his great task, the subjugation of the Latins and the conquest of Rome, could not be accomplished with his own forces and those of his Italian allies alone. Its accomplishment depended on the council at Carthage, on the head-quarters at Cartagena, on the courts of Pella and of Syracuse. If all the energies of Africa, Spain, Sicily, and Macedonia should now be exerted in common against the common enemy; if Lower Italy should become the great rendezvous for the armies and fleets of the west, south, and east; he might hope successfully to finish what the vanguard under his leadership had so brilliantly begun. The most natural and easy course would have been to send to him adequate support from home; and the Carthaginian state, which had remained almost untouched by the war and had been brought from deep decline so near to complete victory by a small band of resolute patriots acting of their own accord and at their own risk, could beyond doubt have done this. That it would have been possible for a Phoenician fleet of any desired strength to effect a landing at Locri or Croton, especially as long as the port of Syracuse remained open to the Carthaginians and the fleet at Brundisium was kept in check by Macedonia, is shown by the unopposed disembarkation at Locri of 4000 Africans, whom Bomilcar about this time brought over from Carthage to Hannibal, and still more by Hannibal's undisturbed embarkation, when all had been already lost. But after the first impression of the victory of Cannae had died away, the peace party in Carthage, which was at all times ready to purchase the downfall of its political opponents at the expense of its country, and which found faithful allies in the shortsightedness and indolence of the citizens, refused the entreaties of the general for more decided support with the half-simple, half-malicious reply, that he in fact needed no help inasmuch as he was really victor; and thus contributed not much less than the Roman senate to save Rome. Hannibal, reared in the camp and a stranger to the machinery of civic factions, found no popular leader on whose support he could rely, such as his father had found in Hasdrubal; and he was obliged to seek abroad the means of saving his native country - means which itself possessed in rich abundance at home.

For this purpose he might, at least with more prospect of success, reckon on the leaders of the Spanish patriot army, on the connections which he had formed in Syracuse, and on the intervention of Philip. Everything depended on bringing new forces into the Italian field of war against Rome from Spain, Syracuse, or Macedonia; and for the attainment or for the prevention of this object wars were carried on in Spain, Sicily, and Greece. All of these were but means to an end, and historians have often erred in accounting them of greater importance. So far as the Romans were concerned, they were essentially defensive wars, the proper objects of which were to hold the passes of the Pyrenees, to detain the Macedonian army in Greece, to defend Messana and to bar the communication between Italy and Sicily. Of course this defensive warfare was, wherever it was possible, waged by offensive methods; and, should circumstances be favourable, it might develop into the dislodging of the Phoenicians from Spain and Sicily, and into the dissolution of Hannibal's alliances with Syracuse and with Philip. The Italian war in itself fell for the time being into the shade, and resolved itself into conflicts about fortresses and razzias, which had no decisive effect on the main issue. Nevertheless, so long as the Phoenicians retained the offensive at all, Italy always remained the central aim of operations; and all efforts were directed towards, as all interest centred in, the doing away, or perpetuating, of Hannibal's isolation in southern Italy.

Had it been possible, immediately after the battle of Cannae, to bring into play all the resources on which Hannibal thought that he might reckon, he might have been tolerably certain of success. But the position of Hasdrubal at that time in Spain after the battle on the Ebro was so critical, that the supplies of money and men, which the victory of Cannae had roused the Carthaginian citizens to furnish, were for the most part expended on Spain, without producing much improvement in the position of affairs there. The Scipios transferred the theatre of war in the following campaign (539) from the Ebro to the Guadalquivir; and in Andalusia, in the very centre of the proper Carthaginian territory, they achieved at Illiturgi and Intibili two brilliant victories. In Sardinia communications entered into with the natives led the Carthaginians to hope that they should be able to master the island, which would have been of importance as an intermediate station between Spain and Italy. But Titus Manlius Torquatus, who was sent with a Roman army to Sardinia, completely destroyed the Carthaginian landing force, and reassured to the Romans the undisputed possession of the island (539). The legions from Cannae sent to Sicily held their ground in the north and east of the island with courage and success against the Carthaginians and Hieronymus; the latter met his death towards the end of 539 by the hand of an assassin. Even in the case of Macedonia the ratification of the alliance was delayed, principally because the Macedonian envoys sent to Hannibal were captured on their homeward journey by the Roman vessels of war. Thus the dreaded invasion of the east coast was temporarily suspended; and the Romans gained time to secure the very important station of Brundisium first by their fleet and then by the land army which before the arrival of Gracchus was employed for the protection of Apulia, and even to make preparations for an invasion of Macedonia in the event of war being declared. While in Italy the war thus came to a stand, out of Italy nothing was done on the part of Carthage to accelerate the movement of new armies or fleets towards the seat of war. The Romans, again, had everywhere with the greatest energy put themselves in a state of defence, and in that defensive attitude had fought for the most part with good results wherever the genius of Hannibal was absent. Thereupon the short-lived patriotism, which the victory of Cannae had awakened in Carthage, evaporated; the not inconsiderable forces which had been organized there were, either through factious opposition or merely through unskilful attempts to conciliate the different opinions expressed in the council, so frittered away that they were nowhere of any real service, and but a very small portion arrived at the spot where they would have been most useful. At the close of 539 the reflecting Roman statesman might assure himself that the urgency of the danger was past, and that the resistance so heroically begun had but to persevere in its exertions at all points in order to achieve its object.
