Machanidas at first looked as though he meant to attack the enemy’s right wing in column; 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 ground was flat and suitable for cavalry. Whereupon Machanidas was constrained to follow suit by sending his Tarentines forward also. [Sidenote: Defeat of the Achaean right wing.] +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. 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.
