14. About the same time, and, as some writers say, on the same day, the Achaeans defeated Androsthenes, the king's commander, in a general engagement near Corinth. [2] Philip, intending to use this city as a citadel, to awe the states of Greece, had invited the principal inhabitants to a conference, under pretence of agreeing with them as to the number of horsemen which the Corinthians could supply towards the war, and these he detained as hostages. [3] Besides the force already there, consisting of five hundred Macedonians and eight hundred auxiliaries of [4??] various kinds, he had sent thither one thousand Macedonians, one thousand two hundred Illyrians, and of Thracians and Cretans (for these served in both the opposite armies) eight hundred. [5] To these were added Bœotians, Thessalians, and Acarnanians, to the amount of one thousand, all carrying bucklers; with as many of the young Corinthians themselves, as filled up the number of six thousand men under arms, —a force which inspired Androsthenes with a confident wish to decide the matter in the field. [6] Nicostratus, praetor of the Achaeans, was at Sicyon, with two thousand foot and one hundred horse; but seeing himself so inferior, both in the number and kind of troops, he did not go outside the walls: [7] the king's forces, in various excursions, were ravaging the lands of Pellene, Phliasus, and Cleone. [8] At last, reproaching the enemy with cowardice, they passed over into the territory of Sicyon, and, sailing round Achaia, [p. 1454]laid waste the whole coast. [9] As the enemy, while thus employed, spread themselves about too widely and too carelessly, (the usual consequence of too much confidence,) Nicostratus conceived hopes of attacking them by surprise. He therefore sent secret directions to all the neighbouring states, as to what day, and what number from each state, should assemble in arms at Apelaurus, a place in the territory of Stymphalia. [10] All being in readiness at the time appointed, he marched thence immediately; [11] and, without the knowledge of any one as to what he was contemplating, came by night through the territory of the Phliasians to Cleone. [12] He had with him five thousand foot, of whom * * * * * *¹ were light-armed, and three hundred horse; with this force he waited there, having despatched scouts to watch on what quarter the enemy should make their irregular inroads.
