At last a considerable body of troops, consisting of a division that was under the personal charge of Pyrrhus himself, succeeded in breaking through the Spartan lines, at a point near one end of the rampart which had been thrown up. When the men found that they had forced their way through, they raised loud shouts of exultation and triumph, and immediately rushed forward toward the city. For a moment it seemed that for the Spartans all was lost; but the tide of victory was soon suddenly turned by a very unexpected incident. An arrow pierced the breast of the horse on which Pyrrhus was riding, and gave the animal a fatal wound. The horse plunged and reared in his agony and terror, and then fell, throwing Pyrrhus to the ground. This occurrence, of course, arrested the whole troop in their progress. The horsemen wheeled suddenly about, and gathered around Pyrrhus to rescue him from his danger. This gave the Spartans time to rally, and to bring up their forces in such numbers that the Macedonian soldiers were glad to be able to make their way back again, bearing Pyrrhus with them beyond the lines. After recovering a little from the agitation produced by this adventure, Pyrrhus found that his troops, discouraged, apparently, by the fruitlessness of their efforts, and especially by this last misfortune, were beginning to lose their spirit and ardor, and were fighting feebly and falteringly all along the line. He concluded, therefore, that there was no longer any prospect of accomplishing his object that day, and that it would be better to save the remaining strength of his troops by withdrawing them from the field, rather than to discourage and enfeeble them still more by continuing what was now very clearly a useless struggle. He accordingly put a stop to the action, and the army retired to their encampment.
