And now there occurred an undoubted instance of what some doubt, namely, that the issues in war are for the most part decided by the skill or want of skill of the commanders. For though perhaps it is a great thing to be able to follow up a first success properly, it is a greater thing still that, when the first step has proved a failure, a man should retain his presence of mind, keep a good look-out for any error of judgment on the part of the victors, and avail himself of their mistakes. At any rate one often sees the side, which imagines itself to have obtained a clear victory, ultimately lose the day; while those who seemed at first to have failed recover themselves by presence of mind, and ultimately win an unexpected victory. Both happened on this occasion to the respective leaders. [Sidenote: Machanidas pursues the fugitives, and thus allows the Achaean hoplites to get between him and his quarters.] The whole of the Achaean mercenaries having been driven from their ground, and their left wing having been thoroughly broken up, Machanidas abandoned his original plan of winning the day by outflanking the enemy with some of his forces and charging their front with others, and did neither; but, quite losing his head, rushed forward heedlessly with all his mercenaries in pursuit of the fugitives, as though the panic was not in itself sufficient to drive those who had once given way up to the town gates. [Sidenote: The fight at the dyke.] +15.+ Meanwhile the Achaean general was doing all he could to rally the mercenaries, addressing the officers by name, and urging them to stand; but when he saw that they were hopelessly beaten, he did not run away in a panic nor give up the battle in despair, but, withdrawing under cover of his phalanx, waited until the enemy had passed him in their pursuit, and left the ground on which the fighting had taken place empty, and then immediately gave the word to the front companies of the phalanx to wheel to the left, and advance at the double, without breaking their ranks. He thus swiftly occupied the ground abandoned by his mercenaries, and at once cut off the pursuers from returning, and got on higher ground than the enemy’s right wing. He exhorted the men to keep up their courage, and remain where they were, until he gave the word for a general advance; and he ordered Polybius of Megalopolis[21] to collect such of the Illyrians and body armour men and mercenaries as remained behind and had not taken part in the flight, and form a reserve on the flank of the phalanx, to keep a look-out against the return of the pursuers. Thereupon the Lacedaemonians, excited by the victory gained by the light-armed contingent, without waiting for the word of command, brought their sarissae to the charge and rushed upon the enemy. But when in the course of their advance they reached the edge of the dyke, being unable at that point to change their purpose and retreat when at such close quarters with the enemy, and partly
