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.
So they set up a trophy on the headland where the Cynossema stands, brought in the wreckage, restored to the enemy their dead under a truce, and sent a trireme to Athens to announce their victory.
When the ship arrived and the Athenians heard the news of the good fortune that was beyond their hopes, coming as it did on the heels of the disasters that had recently befallen them in Euboea and in the course of their factional dissensions, they were greatly encouraged, and believed that their cause might still prevail if they should zealously lay their hands to the work.
On the fourth day after the battle, after they had hastily refitted their ships, the Athenians at Sestos sailed against Cyzicus, which had revolted; and descrying the eight ships from Byzantium[*](cf. 8.80.4.) lying at anchor off Harpagium and Priapus, they sailed against them, defeated in battle the forces which on shore aided them, and captured the ships. Then going on to Cyzicus, they brought it back into the Athenian alliance, since it had no walls, and levied upon it a fine of money.
Meanwhile the Peloponnesians on their part left Abydus and sailed to Slaeus, where they recovered such of their captured ships as were sound—the Elaeusians had burned the rest—and sent Hippocrates and Epicles to Euboea to fetch the ships that were there.
