History of the Peloponnesian War

And now, when the Athenians attacked them, both by sea with their fleet and on land, having put men ashore, there was great confusion and disorder; and most of the Peloponnesian ships were disabled by the Athenians on the beach and their commander Alcamenes was slain. And some Athenians also were killed.

After drawing off, the Athenians posted a sufficient number of ships to keep watch upon those of the enemy, but with the rest cast anchor at an islet not far distant, on which they proceeded to make their camp; and they also sent to Athens for reinforcements.

For the Corinthians had joined the Peloponnesians the day after the battle, bringing reinforcements to their fleet, and not long afterward the peoples of the neighbourhood also came. And the Peloponnesians, seeing the difficulty of guarding the ships in a desert place, were in perplexity; and they even thought of burning the ships, but afterwards determined to draw them up on shore and, settling down there with their land-force, to keep guard over them until some favourable opportunity of escape should offer. And Agis, hearing of their predicament, sent to them Thermon, a Spartan.
