History of the Peloponnesian War

After these things, in the course of the same summer, the Chians went on as they had begun, without any falling off in their zeal; and as they found themselves, even independently of the Lacedaemonians, with a large force for bringing over the states, and at the same time were desirous that as many as possible should share the danger with them, they made an expedition by themselves with thirteen ships to Lesbos, according to the arrangement of the Lacedaemonians to go to that island in the second place, and thence to the Hellespont, while at the same time the land forces of the Peloponnesians who were there, and of the allies from the country itself, moved along shore towards Clazomenae and Cuma; the commander of the troops being Evalas, a Spartan, and of the ships, Diniadas, one of the Perioeci.

The fleet having sailed first to Methymna, effected the revolt of the place, and four vessels were left there; while the remainder, again, effected that of Mytilene also.
