History of the Peloponnesian War

The Athenians thought at first that they would make an attempt on the land side alone, but when they saw their fleet also suddenly coming against them, they were thrown into alarm; and some were making preparations on and in front of the walls to meet the attack, while others marched out against those who with all speed were coming from the Olympieum and the parts outside the city—both horse in great numbers and dart-men—and others proceeded to man the ships, and at once ran to the beach to oppose the enemy. And when they were manned, they put out against them with seventy-five vessels, those of the Syracusans being about eighty in number.

For a great part of the day they continued advancing and retiring and making attempts upon one another; and when neither party could gain any advantage worth mentioning, except that the Syracusans sank one or two of the Athenians' ships, they separated; and the troops at the same time withdrew from the walls.
