Machanidas had now acquired great confidence, and looked upon the determination of the Achaeans as extremely favourable to his plans. As soon as he heard of their being in force at Mantinea, he duly harangued his Lacedaemonians at Tegea, and the very next morning at daybreak advanced upon Mantinea. He led the right wing of the phalanx himself; his mercenaries marched in two parallel columns on each side of his front; and behind them were carts carrying quantities of field artillery and bolts for the catapults. Meanwhile Philopoemen too had arranged his army in three divisions, and was leading them out of Mantinea, the Illyrians and the men with body armour by the gate leading to the temple of Poseidon, and with them all the rest of the foreign contingent and light-armed troops; by the next gate, toward the west, the phalanx; and by the next the Achaean cavalry. He sent his light-armed men forward to occupy the hill, which rises to a considerable height above the road called Xenis and the above-mentioned temple: he stationed the men with body armour next, resting on this hill to the south; next them the Illyrians; next them, in the same straight line, the phalanx, drawn up in companies, with an interval between each, along the ditch which runs towards the temple of Poseidon, right through the middle of the plain of Mantinea, until it touches the range of mountains that forms the boundary of the territory of the Elisphasii. Next to them, on the right wing, he stationed the Achaean cavalry, under the command of Aristaenetus of Dyme; while on the left wing he led the whole of the foreign contingent, drawn up in lines one behind the other.
