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.

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.
