History of the Peloponnesian War

For the Corcyraeans began their sedition on the return home of the prisoners taken in the sea-fights off Epidamnus, who had been sent back by the Corinthians, nominally on the security of eight hundred talents given for them by their proxeni, but in reality, because they had consented to bring over Corcyra to the Corinthians. These men then were intriguing, by visits to each of the citizens, to cause the revolt of the city from the Athenians.

On the arrival of a ship from Athens and another from Corinth, with envoys on board, and on their meeting for a conference, the Corcyraeans voted to continue allies of the Athenians according to their agreement, but to be on friendly terms with the Peloponnesians, as they had formerly been.
