After setting up a trophy upon Point Cynossema, securing the wrecks, and restoring to the enemy his dead under truce, they sent off a galley to Athens with the news of their victory.
The arrival of this vessel with its unhoped-for good news, after the recent disasters of Euboea, and in the revolution at Athens, gave fresh courage to the Athenians, and caused them to believe that if they put their shoulders to the wheel their cause might yet prevail.
On the fourth day after the sea-fight the Athenians in Sestos having hastily refitted their ships sailed against Cyzicus, which had revolted. Off Harpagium and Priapus they sighted at anchor the eight vessels from Byzantium, and sailing up and routing the troops on shore, took the ships, and then went on and recovered the town of Cyzicus, which was unfortified, and levied money from the citizens.
