Notwithstanding his recent defeats, he had 'left a name at which the world grew pale,' and during the sixteen years he had spent in Italy none had dared to molest him. Single-handed he had fought; was it possible that at last his hour of triumph was at hand? * * * * * Now that Hannibal, whom they had deserted and betrayed, was really in Africa the weak and foolish citizens of Carthage sent orders to him to fight without delay. For answer he bade the messengers 'confine their attention to other matters, and leave such things to him, for he would choose for himself the time of fighting,' and without more ado he began collecting a number of elephants and all the Numidian horse that had not gone over to Rome with Massinissa. He was labouring night and day at this task when again his plans were spoilt by some citizens of Carthage, who broke the truce which had been made by seizing some Roman ships. Scipio lost no time in avenging himself by burning all the towns and villages on the plain, and occupying the passes on a range of mountains where Hannibal had hoped to take up his position. Baulked in this project, Hannibal sent to Scipio to beg for an interview, and tried to obtain for Carthage better terms than the Roman was inclined to grant. 'You have broken the truce by capturing the vessel containing the Roman envoys,' he said, 'and now you and your country must throw yourselves on our mercy, or else conquer us.' * * * * * So the armies drew up opposite each other on the field of Zama, on the bright spring morning of 202 B.C. which was to decide whether Carthaginians or Romans were to be masters of the world. Hannibal had about five thousand men more than his enemy, but he was weak in cavalry, and the eighty elephants which he had placed in front were young and untrained. The cavalry of the Romans was under the command of Massinissa and of Laelius, friend of the historian Polybius, and it was this strong body of Numidian horse which ultimately turned the fate of the day. As for the elephants, the sound of the Roman trumpets frightened them before the battle had begun, and threw them into confusion. They charged right into the middle of the Carthaginian cavalry, followed by Massinissa and by Laelius, who succeeded in breaking the ranks of the horse and putting them to flight. For a moment it seemed as if the heavy armed foreign troops which Hannibal then brought up would prevail against the Roman legions, but at length they were forced back on to their own lines, which took them for deserters. With a cry of 'Treachery!' the foreign soldiers fell on the Carthaginians, and fighting hard they retreated on Hannibal's reserve, the well-trained Italians. * * * * *
