The Argives had received notice of the advance of Agis, and they immediately marched out to meet him, wishing to engage the Spartans before they had united with their allies from Corinth, Boeotia, and elsewhere, who were assembling in great force at Phlius. The two armies confronted each other for a moment at Methydrium, in Arcadia; but Agis succeeded in avoiding an engagement, and breaking up his camp under cover of darkness pushed on to Phlius. Thereupon the Argives, who were accompanied by their allies from Mantinea and Elis, returned in haste to Argos, and then, marching northwards, took up their position at Nemea, which commanded the ordinary route from Phlius to the Argive territory. But they were again outmanoeuvred by the skilful dispositions of Agis. Avoiding the road by Nemea, which led through a narrow and dangerous pass, he led his Spartans over the mountains and descended into the plain which surrounds the city of Argos. One contingent of his allies had orders to proceed in the same direction by another mountain-path, while the Boeotians, who numbered no less than ten thousand infantry, and five hundred cavalry, were directed to take the high road by Nemea; for Agis expected that by threatening the cultivated lands around Argos he would draw the Argives from their position, and bring them down in haste to the defence of their estates. The plan was completely successful. As soon as the Argives learnt that Agis was ravaging their fields they set out with all speed towards Argos, and finding Agis engaged in the work of pillage, they drew up their forces, and offered battle. Their situation was in the highest degree perilous. In front of them, cutting them off from the city of Argos, was the flower of the Spartan army, reinforced by the troops of Tegea and Arcadia; on their right flank the mountain slopes swarmed with the infantry of Corinth and Phlius; and in the rear their retreat was cut off by the thronging masses of Boeotians, who were now pouring along the road from Nemea. They were fairly cut off, and seemed delivered over to destruction; nevertheless, such was the presumptuous confidence which possessed them, that they awaited eagerly the signal for battle, crying out that they had caught the Spartans in a trap.
