The History of the Peloponnesian War
Page: 197In the middle of the next summer the Lacedaemonians, seeing the Epidaurians, their allies, in distress, and the rest of Peloponnese either in revolt or disaffected, concluded that it was high time for them to interfere if they wished to stop the progress of the evil, and accordingly with their full force, the Helots included, took the field against Argos, under the command of Agis, son of Archidamus, king of the Lacedaemonians. The Tegeans and the other Arcadian allies of Lacedaemon joined in the expedition. The allies from the rest of Peloponnese and from outside mustered at Phlius; the Boeotians with five thousand heavy infantry and as many light troops, and five hundred horse and the same number of dismounted troopers; the Corinthians with two thousand heavy infantry; the rest more or less as might happen; and the Phliasians with all their forces, the army being in their country.
The preparations of the Lacedaemonians from the first had been known to the Argives, who did not, however, take the field until the enemy was on his road to join the rest at Phlius. Reinforced by the Mantineans with their allies, and by three thousand Elean heavy infantry, they advanced and fell in with the Lacedaemonians at Methydrium in Arcadia. Each party took up its position upon a hill, and the Argives prepared to engage the Lacedaemonians while they were alone; but Agis eluded them by breaking up his camp in the night, and proceeded to join the rest of the allies at Phlius.
