History of the Peloponnesian War

But the Athenians, much confirmed by this the Mytilenaeans' cessation, called in their confederates (who, because they saw no assurance on the part of the Lesbians, came much sooner in than was thought they would have done) and, riding at anchor to the south of the city, fortified two camps, on either side one, and brought their galleys before both the ports and so quite excluded the Mytilenaeans from the use of the sea.

As for the land, the Athenians held so much only as lay near their camps, which was not much; and the Mytilenaeans and other Lesbians, that were now come to aid them, were masters of the rest. For Malea served the Athenians for a station only for their galleys and to keep their market in. And thus proceeded the war before Mytilene.
