Philopoemen seemed now lost to all hopes. "On this occasion," says Polybius, "appeared the truth of a maxim, which cannot reasonably be contested, That the events of war are generally successful or unfortunate, only in proportion to the skill or ignorance of the generals who command in them. Philopoemen, so far from desponding at the ill success of the first charge, or being in confusion, was solely intent upon taking advantage of the errors which the enemy might commit." Accordingly, they were guilty of a great one. Machanidas, after the left wing was routed, instead of improving that advantage, by charging in front that instant with his infantry the centre of that of the enemies, and taking it at the same time in flank with his victorious wing, and thereby terminating the whole affair, suffers himself, like a young man, to be hurried away by the fire and impetuosity of his soldiers, and pursues, without order or discipline, those who were flying. Philopoemen, who had retired to his infantry in the centre, takes the first cohorts, commands them to wheel to the left, and at their head marches and seizes the post which Machanidas had abandoned. By this movement he divided the centre of the enemies' infantry from his right wing. He then commanded these cohorts to stay in the post they had just seized, till further orders; and at the same time directed a Megalapolitan to rally all the Illyrians, cuirassiers, and foreigners, who, without quitting their ranks, and flying as the rest had done, had drawn off, to avoid the fury of the conqueror; and with these forces to post himself on the flank of the infantry in his centre, to check the enemy in their return from the pursuit. This Megalapolitan was named Polyinus; but not the historian, as many writers have imagined. The Lacedæmonian infantry, elated with the first success of their wing, without waiting for the signal, advanced with their pikes lowered towards the Achæans, as far as the brink of the ditch. This was the decisive point of time for which Philopoemen had long waited, and thereupon he ordered the charge to be sounded. His troops levelling their pikes, fell with dreadful shouts on the Lacedemonians. These, who at their descending into the ditch, had broken their ranks, no sooner saw the enemy above them, but immediately fled.
