After the rout was thus effected, the Peloponnesians fled for refuge for the most part to the river Pydius at first, but afterwards to Abydus. The Athenians took only a few ships—for the Hellespont is narrow and afforded their opponents places of refuge near at hand—yet the victory which they won in this battle was indeed most opportune.
Hitherto they had been afraid of the Peloponnesian feet, on account not only of the gradual losses[*](cf. 8.42.4; 8.95.7; 8.102.2.) they had suffered, but especially of their disaster in Sicily; but now they ceased either to reproach themselves or to consider their enemy any longer of any account in naval matters.
However, they did capture of the enemy's fleet eight Chian ships, five Corinthian, two Ambracian, two Boeotian, and one each belonging to the Leucadians, Lacedaemonians, Syracusans, and Pellenians; and they lost fifteen themselves.
