The slaughter that followed was terrible. It was said that seventy thousand mountaineers were left dead on the battle-field. That is impossible. Many of the tribesmen fled as soon as they saw that the day was not to be theirs, and these must have secured such a start as to make their escape easy. But the victorious cavalry went on slaying till their arms were weary.
The safety of the mercenaries and the third division of the phalanx was now seriously compromised. They had, fortunately, effected a junction before the battle began, and it was of course a necessity that they should keep together. So much was certain, but it was not equally certain what was the best course for them to follow. The Carthaginians were anxious to return, if return was in any way possible, to the city. Their families, their friends, everything in fact that they held dear was there; it was only too probable that unless they got back at once they would never see the city or them again. The mercenaries, on the other hand, were bent on returning to the fortress of Nepheris, from which they had sallied forth. The fortress was near, so near that the legions could not bar their way, though the light-armed troops and the cavalry might molest them on the march.
A hurried council of war was held; there was no time for discussion. Each officer—there were seven of rank to vote—gave his decision without reasons. Considerations of safety, which were overwhelmingly strong in favour of a retreat on the fortress of Nepheris, carried the day. Five voted for this course, and a sixth, who had originally declared for cutting their way through to Carthage, changed his mind when he saw himself in a small minority.
Only Hasdrubal was left in opposition. "I swore to defend Carthage, not Nepheris," he exclaimed. Then, with an unconscious imitation of the obstinate Spartan at Platæa, he took a huge stone from the ground and threw it down in front of him, saying, "I give my vote for remaining."[39]
Cleanor's private opinion was that his chief's obstinacy was nothing else than madness, but he could not leave the general to whose person he had been attached.
If Hasdrubal had thought that his opposition would determine the action of his colleagues he was mistaken. Without a word—and indeed there was no time for argument—they moved off in the direction of the fortress. Hasdrubal was brought to his senses by this decisive action, just as the Spartan had been before him. Nor could he mistake the meaning of the agitation that at once showed itself among his men. It was not difficult to see that he would soon be left almost alone.
Accordingly he gave the signal to march. Some time, however, had been lost, and a number of light-armed troops from the Roman army were within a short distance of the retreating force. It became necessary, if their attacks were to be checked, for the rear ranks to face about. There was little or no actual fighting. The pursuers fell back as soon as the retreating division showed them a firm front. Their object was to cause as much delay as possible; the Carthaginians, on the other hand, had to solve the problem of making these necessary halts interfere as little as possible with the rapidity of their retreat. In this they were greatly helped by their high discipline and what may be called their perfect coherence, and they had actually got almost within a bow-shot of the rock-fortress when they had to turn, as they hoped, for the last time.
There was now some really sharp fighting. The pursuers had been reinforced by a detachment of picked troops from the main body, men chosen for the speed with which they could move under a heavy equipment of armour and arms. The Carthaginians fell slowly back before them, keeping an unbroken line, and encouraged by the thought that if they could get within range of the walls they would be in comparative safety.
Nor was this hope disappointed. The Romans, indeed, pressed on, for the walls were to all appearance deserted, but this appearance concealed a carefully concerted surprise. Hundreds of archers and slingers were crouching behind the battlements, and there were scores of catapults, with their range carefully adjusted, ready to discharge volleys of stones and javelins. At a given signal, fire, if the expression may be allowed, was opened with overwhelming effect. The Roman line absolutely staggered under the blow. At the same time the gates were thrown open, and before the enemy could recover, the whole of the retreating force was safe within the walls.
But when, an hour or so afterwards, the roll was called, Cleanor was among the missing.
