Had the Carthaginian army only consisted of old and well-seasoned troops all might have gone well with it; but the large body of Gauls were totally untrained, and in their disappointment at not being allowed to give battle, seized on all the drink in the camp, and fell along the roadside quite unable to move. Before Hasdrubal could get his vanguard across the Romans were close upon him, and there was nothing left for him to do but to post his men as strongly as he could.
For hours they fought, and none could tell with whom the victory would lie: then a charge by Nero decided it. When the day was hopelessly lost, Hasdrubal, who had always been in the fiercest of the struggle, cheering and rallying his men, rode straight at the enemy, and died fighting. Thus ended the battle of the Metaurus, the first pitched battle the Romans had ever gained over the Carthaginian army.
The next night Nero set off again for Apulia, bearing with him the head of Hasdrubal, which, as we have said, he caused to be flung into Hannibal's tent, staining for ever the laurels he had won.
With the triumph of Nero, and his reception in the Rome which he had delivered, dates the last act of the second Punic war. At the news of his brother's defeat, which was a great blow to him, Hannibal retreated into the most southern province of Italy. His troops, whose love and loyalty never wavered, were largely composed of foreign levies, and had not the steadiness and training of his old Libyans and Spaniards. Never for one moment did he think of abandoning his post till his country called him, yet his quick eye could not fail to read the signs of the times. The Roman senate was no longer absorbed by the thought of war. Relieved by Nero's victory from the crushing dread which for so long had weighed it down, it was taking measures to encourage agriculture and to rebuild villages, to help the poor who had been ruined during these years of strife, to blot out, he felt, the traces of the victories he had won. And he had to watch it all and to know himself powerless, though he still defied Rome for three years longer, and knew that she still feared him.
It was in the year 204 b.c. that Scipio entreated the senate to allow him to carry the war into Africa, which he had already visited, and where he had already made many important allies, among them the famous Numidian Massinissa, whom he promised to make king over his tribe. Fabius, now ninety, declared it was folly to take an army to Africa while Hannibal remained in Italy, and a large party agreed with him. The people, however, who had absolute trust in the young general, insisted that he should have his way; and after a long and fierce debate, the senate with almost inconceivable foolishness consented that Scipio should sail for Carthage, as he so much desired it, but that he must do so at the head of no more than thirty thousand or forty thousand men.
That so practical and sensible a nation should not have remembered the lesson of the defeat of Regulus, and have known the dangers which must be run by a small army in a foreign land, is truly surprising, and had Massinissa, with his priceless Numidian horse, not joined the Romans, Scipio's army would more than once have been almost certainly cut to pieces.
When it became known that Scipio had landed and was besieging the old town of Utica, the rich and pleasure-loving citizens of Carthage were filled with despair. But this did not last long, for one of the leading men of the city, called Hanno, collected a small force, while Hasdrubal Gisco and Syphax the Numidian raised another, and between them both Scipio was forced to retreat. If only Hannibal had been there——But Hannibal was still in Italy, and no tidings of the struggle had reached him.
