History of the Peloponnesian War

For the Corinthians, after the ambassadors came to them, and brought a more favourable report of affairs in Sicily, thinking that they had not been unseasonable in sending their former squadron, were now much more encouraged, and prepared, on their part, to despatch heavy-armed troops for Sicily in vessels of burden, as the Lacedaemonians did likewise from the rest of the Peloponnese.

The Corinthians manned also five and twenty triremes, to try the result of a battle with the squadron keeping watch at Naupactus, and that the Athenians there might be less able to prevent their transports from putting out, having to keep an eye upon the Corinthian line of triremes drawn up against them.
