History of the Peloponnesian War

However, Agis, instead of taking this road as they expected, gave the Lacedaemonians, Arcadians, and Epidaurians their orders, and went along another difficult road, and descended into the plain of Argos. The Corinthians, Pellenians, and Phliasians marched by another steep road; while the Boeotians, Megarians, and Sicyonians had instructions to come down by the Nemean road where the Argives were posted, in order that if the enemy advanced into the plain against the troops of Agis, they might fall upon his rear with their cavalry.

These dispositions concluded, Agis invaded the plain and began to ravage Saminthus and other places.

Discovering this, the Argives came up from Nemea, day having now dawned. On their way they fell in with the troops of the Phliasians and Corinthians, and killed a few of the Phliasians, and had perhaps a few more of their own men killed by the Corinthians.

Meanwhile the Boeotians, Megarians, and Sicyonians, advancing upon Nemea according to their instructions, found the Argives no longer there, as they had gone down on seeing their property ravaged, and were now forming for battle, the Lacedaemonians imitating their example.

The Argives were now completely surrounded; from the plain the Lacedaemonians and their allies shut them off from their city; above them were the Corinthians, Phliasians, and Pellenians; and on the side of Nemea the Boeotians, Sicyonians, and Megarians. Meanwhile their army was without cavalry, the Athenians alone among the allies not having yet arrived.
