History of the Peloponnesian War

After the festival the Peloponnesians set sail for Chios with one and twenty ships under the command of Alcamenes; and the Athenians, having at first advanced against them with an equal number, then began to retreat towards the open sea. When the enemy did not follow them far, but drew back, the Athenians likewise returned; for they had the seven Chian vessels in the number of those with them, and did not consider them trustworthy.

Afterwards, having manned others, so as to make in all thirty-seven, while the enemy were coasting along, they chased them into Piraeus, in the Corinthian territory. This is a desert port, on the extreme borders of Epidaurus. The Peloponnesians lost one ship out at sea, but collected the rest, and brought them to anchor.

And now, when the Athenians both attacked them by sea with their ships, and had landed on the shore, there was a great disorder and confusion; and the Athenians severely damaged most of their ships on the beach, and killed Alcamenes their commander; whilst some also fell on their own side.
