the ambassadors from Athens returned without having effected anything; and hostilities were at once begun by the Mitylenians and the rest of Lesbos, with the exception of the Methymnians, who came to the aid of the Athenians with the Imbrians and Lemnians and some few of the other allies. The Mitylenians made a sortie with all their forces against the Athenian camp; and a battle ensued, in which they gained some slight advantage, but retired notwithstanding, not feeling sufficient confidence in themselves to spend the night upon the field. After this they kept quiet wishing to wait for the chance of reinforcements arriving from Peloponnese before making a second venture, being encouraged by the arrival of Meleas, a Laconian, and Hermaeondas, a Theban, who had been sent off before the insurrection but had been unable to reach Lesbos before the Athenian expedition, and who now stole in in a trireme after the battle, and advised them to send another trireme and envoys back with them, which the Mitylenians accordingly did.
