History of the Peloponnesian War

The Athenians also made a descent with a fleet upon Halieis, where they had a battle with some Corinthians and Epidaurians, in which the Corinthians won. And afterwards the Athenians fought a sea-fight at Cecryphaleia with a Peloponnesian fleet, in which the Athenians won.

After this war broke out between the Athenians and the Aeginetans, and a great sea-fight occurred between the Athenians and the Aeginetans off Aegina, in which the allies of both sides were present. This the Athenians won and having taken seventy Aeginetan ships they descended upon their territory and laid siege to the city, Leocrates son of Stroebus, being in command.

Thereupon the Peloponnesians, wishing to aid the Aeginetans, sent into Aegina three hundred hoplites, who had previously been assisting the Corinthians and Epidaurians. Moreover, the Corinthians occupied the heights of Geraneia, and made a descent upon the territory of M egara in conjunction with their allies, thinking that the Athenians would be unable to aid the Megarians, since many of their troops were away in Aegina and in Egypt, or if they should attempt it that they would have to withdraw from Aegina.

The Athenians, however, did not disturb the army besieging Aegina, but with such forces as were left in the city, consisting of the oldest and the youngest men, marched into Megara, the general in command being Myronides.

An indecisive battle was fought with the Corinthians, whereupon they separated, each side thinking they had not got the worst of it in the action.

And the Athenians, who had in fact got rather the better of it, when the Corinthians withdrew, set up a trophy; but the Corinthians, being reproached by the older men in their city, made their preparations and about twelve days later came back and set up for themselves a rival trophy, as though they had won. Hereupon the Athenians made a sally from Megara, slew those who were setting up the trophy, and joining battle with the rest defeated them.
