[12.] As soon as the enemy were well in sight, Philopoemen went down the ranks of the phalanx, and addressed to them an exhortation which, though short, clearly pointed out to them the nature of the battle in which they were engaged. But most of what he said was rendered inaudible by the answering shouts of the troops. The affection and confidence of the men rose to such a pitch of enthusiasm and zeal that they seemed to be almost acting under a divine inspiration, as they cried out to him to lead them on and fear nothing. However he tried, when he could get the opportunity, to make this much clear to them, that the battle on the one side was to establish a shameful and ignominious servitude, on the other to vindicate an ever-memorable and glorious liberty.

Machanidas at first looked as though he meant to attack the enemy’s right wing in column;The attack of Machanidas. but when he got within moderate distance he deployed into line by the right, and by this extension movement made his right wing cover the same amount of ground as the left wing of the Achaeans, and fixed his catapults in front of the whole force at intervals. Philopoemen understood that the enemy’s plan was, by pouring volleys from the catapults into his phalanx, to throw the ranks into confusion: he therefore gave him no time or interval of repose, but opened the engagement by a vigorous charge of his Tarentines[20] close to the temple of Poseidon, where the groundThe battle begun by light-cavalry charges. was flat and suitable for cavalry. Whereupon Machanidas was constrained to follow suit by sending his Tarentines forward also.

[13.] At first the struggle was confined to these two forces, and was maintained with spirit. But the light-armed troops coming gradually to the support of such of them as were wavering, in a very short time the whole of the mercenaries on either side were engaged. They fought sometimes in close order, sometimes in pairs: and for a long time so entirely without decisive result, that the rest of the two armies, who were watching in which direction the cloud of dust inclined, could come to no conclusion, because both sides maintained for a long while exactly their original ground. Defeat of the Achaean right wing. But after a time the mercenaries of the tyrant began to get the better of the struggle, from their numbers, and the superiority in skill obtained by long practice. And this is the natural and usual result. The citizens of a democracy no doubt bring more enthusiasm to their battles than the subjects of a tyrant; but in the same proportion the mercenaries of sovereigns are naturally superior and more efficient than those of a democracy. For in the former case one side is fighting for liberty, the other for a condition of servitude; but in the case of mercenaries, those of the tyrant are encouraged by the certain prospect of reward, those of a democracy know that they must lose by victory: for as soon as a democracy has crushed its assailants, it no longer employs mercenaries to protect its liberties; while a tyranny requires more mercenaries in proportion as its field of ambition is extended: for as the persons injured by it are more numerous, those who plot against it are more numerous also; and the security of despots rests entirely on the loyalty and power of mercenaries.

[14.] Thus it came about that the mercenaries in the army of Machanidas fought with such fury and violence, that even the Illyrians and men with body armour, who formed the reserve supporting the mercenaries of the Achaean army, were unable to withstand their assault; but were all driven from their position, and fled in confusion towards the city of Mantinea, which was about seven stades distant.

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.

The whole of the Achaean mercenaries having been driven from their ground, and their left wing having beenMachanidas pursues the fugitives, and thus allows the Achaean hoplites to get between him and his quarters. 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.

[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. The fight at the dyke. 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 because they did not consider the dyke a serious obstacle, as the slope down to it was very gradual, and it was entirely without water or underwood growing in it, they continued their advance through it without stopping to think.

[16.] The opportunity for attack which Philopoemen had long foreseen had now arrived. He at once ordered the phalanx to bring their sarissae to the charge and advance. The men obeyed with enthusiasm, and accompanied their charge with a ringing cheer. The ranks of the Lacedaemonians had been disorganised by the passage of the dyke, and as they ascended the opposite bank they found the enemy above them. They lost courage and tried to fly; but the greater number of them were killed in the ditch itself, partly by the Achaeans, and partly by trampling on each other. Now this result was not unpremeditated or accidental, but strictly owing to the acuteness of the general. For Philopoemen originally took ground behind the dyke, not to avoid fighting, as some supposed, but from a very accurate and scientific calculation of strategical advantages. He reckoned either that Machanidas when he arrived would advance without thinking of the dyke, and that then his phalanx would get entangled, just as I have described their actually doing; or that if he advanced with a full apprehension of the difficulty presented by the dyke, and then changing his mind and deciding to shrink from the attempt, were to retire in loose order and a long straggling column,[22] the victory would be his, without a general engagement, and the defeat his adversary’s. For this has happened to many commanders, who having drawn up their men for battle, and then concluded that they were not strong enough to meet their opponents, either from the nature of the ground, the disparity of their numbers, or for other reasons, have drawn off in too long a line of march, and hoped in the course of the retreat to win a victory, or at least get safe away from the enemy, by means of their rear guard alone.

[17.] However, Philopoemen was not deceived in his prognostication of what would happen; for the Lacedaemonians were thoroughly routed. Seeing therefore that his phalanx was victorious and that he had gained a complete and brilliant success,Machanidas, returning from the pursuit, is killed while trying to recross the dyke. he set himself vigorously to secure the only thing wanting to complete it, that is, to prevent the escape of Machanidas. Seeing therefore that, in the course of the pursuit, he was caught between the dyke and the town with his mercenaries, he waited for him to attempt a return. But when Machanidas saw that his army was in full retreat, with the enemy at their heels, he knew that he had advanced too far, and had lost his chance of victory: he therefore rallied the mercenaries that he had with him, and tried to form close order, and cut his way through the enemy, while they were still scattered and engaged in the pursuit. Some of his men, understanding his plan and seeing no other hope of safety, kept by him at first; but when they came upon the ground, and saw the Achaeans guarding the bridge over the dyke, they lost heart; and the whole company began falling away from him, each doing the best he could to preserve his own life. Thereupon the tyrant gave up all hope of making his way over the bridge; and rode along the edge of the dyke, trying with all his might to find a place which he could cross.
