For this was indeed the finest Hellenic force that had come together up to that time; and this was seen especially while it was still united at Nemea, including the Lacedaemonians in full force, the Arcadians, Boeotians, Corinthians, Sicyonians, Pellenians, Phliasians, and Megarians, all of them picked men from each nation, who felt themselves to be a match, not for the Argive confederacy only, but even for another such force in addition.
The army, then, thus blaming Agis, withdrew and dispersed severally to their homes.
But the Argives also on their part held in far greater blame those who had made the truce without consulting the people, as they too thought that the Lacedaemonians had escaped, though circumstances could never be more favourable for themselves; for the contest would have been near their own city and in concert with numerous and brave allies.
And so on their return they began to stone Thrasyllus in the bed of the Charadrus,[*](Close under the north-east wall of the city.) where before they enter the city all causes are tried that arise from an expedition. But he fled for refuge to the altar and was saved; his property however was confiscated.
After this, when Athenian reinforcements arrived, consisting of one thousand hoplites and three hundred cavalry, under the command of Laches and Nicostratus, the Argives—for they shrunk in spite of all from breaking off the truce with the Lacedaemonians—bade them go away, and would not comply with their wish to be brought before the people for negotiations, until the Mantineans and Eleans, who were still present, constrained them by their entreaties to do so.
