History of the Peloponnesian War

Meanwhile the Athenian ships from Zacynthus arrived, fifty in number; for they were reinforced by some of the guard-ships at Naupactus, and four Chians.

When they saw both the mainland and the island crowded with heavy-armed, and the ships in the harbour, and not sailing out of it; being at a loss where to get anchorage, they sailed at the time to the island of Prote, which is not far off, and is uninhabited, and there they passed the night. The next day they weighed anchor in readiness for an engagement in the open sea, should the enemy be disposed to put out to meet them there; if not, intending to sail in and attack them.
