The cause of the war in Italy presently began to stagnate more and more, especially after Capua and Tarentum had been retaken (in 211 and 209). Once, and once only, did the Carthaginians venture again to play for high stakes. Hasdrubal had skilfully evaded the Romans in Spain and had reached north Italy by way of the Pyrenees and Alps, intending there to join hands with his brother Hannibal (early in 207 B.C.). It was a critical moment, for both the consuls of the year 208 had fallen in battle. The speedy succour which the newly elected consul, Claudius Nero, despatched to his colleague, Livius, decided the victory in favour of the Romans. Hasdrubal lost both his army and his life (at Sinigaglia) on the banks of the Metaurus. In the meantime the Romans had succeeded in wresting Spain from the Carthaginians. The two elder Scipios, Publius and Cneius, who, after fighting with varying fortune, had advanced as far as the Guadalquivir, both lost their lives in 211 B.C. But Publius Scipio the Younger, afterwards known as Africanus, a man of Hannibal’s own temper, had taken New Carthage (209 B.C.), defeated the Carthaginian armies at Bæcula (208) and Silpia (207), and occupied Gades, the southernmost city of Spain, in 206. Carthage, nevertheless, could only be conquered in Africa. This view had little to commend it in the eyes of many a prudent member of the senate so long as Hannibal remained in Italy. For all that, Scipio succeeded in transferring the theatre of war in 204 from his own province of Sicily to northern Africa. Allying himself with the Numidian prince, Masinissa, he defeated the Carthaginians and their ally, Syphax of Mauretania, in the year 203 B.C., and brought the war to a close by the decisive victory of Zama (202 B.C.), in which he routed Hannibal, who had returned from Italy, and the flower of his troops. Carthage lost not only her fleet and foreign provinces, but her sovereignty itself; she was not allowed to go to war without the permission of Rome, while an irksome sentinel was set over her in the person of her adversary, Masinissa, who had been enriched with Punic territory. Even after this catastrophe the Carthaginians did not utterly lose heart. Their commerce soon revived and prospered, and Hannibal did all he could to restore the prestige of his native city as long as the Romans tolerated his presence there, and to raise up fresh enemies to Rome after he had been driven into exile. Rome was not long left to the tranquil enjoyment of her victory. Peace had been concluded. Not the citizens of Rome alone, but all Italy, yearned for a lasting peace. And yet the Roman senate, in defiance of popular feeling, was constrained to embark promptly on the adventures of a new and perilous war or to be false to the whole tenor of its policy up to that time.
