History of the Peloponnesian War

The next day, after first coasting along to the territory of Epidaurus and making a descent there, they came to Methana between Epidaurus and Troezen, and drew a wall across and fortified the isthmus of the peninsula, and left a post there from which incursions were henceforth made upon the country of Troezen, Haliae, and Epidaurus. After walling off this spot the fleet sailed off home.

While these events were going on, Eurymedon and Sophocles had put to sea with the Athenian fleet from Pylos on their way to Sicily, and arriving at Corcyra, joined the townsmen in an expedition against the party established on Mount Istone, who had crossed over, as I have mentioned, after the revolution, and become masters of the country, to the great hurt of the inhabitants.

Their stronghold having been taken by an attack, the garrison took refuge in a body upon some high ground and there capitulated, agreeing to give up their mercenary auxiliaries, lay down their arms, and commit themselves to the discretion of the Athenian people.
