History of the Peloponnesian War

And now the Boeotians, Megareans, and Sicyonians advanced, as they had been ordered, towards Nemea, and found the Argives no longer there; but they had gone down, on seing their property ravaged, and were forming for battle; while the Lacedaemonians also were preparing to meet them.

Now the Argives were intercepted in the midst of their enemies; for on the side of the plain the Lacedaemonians and those with them excluded them from their city; above them were the Corinthians, Phliasians, and Pellenians; and in the direction of Nemea the Boeotians, Sicyonians, and Megareans. They had no cavalry with them; [*]( Implying, of course, that the Athenians were the only people amongst he confederates who had any cavalry.) for the Athenians alone of all the allies had not yet joined them.
