History of the Peloponnesian War

Such was what they said, and all the Corcyraean armament that were within hearing immediately called out to take them and kill them. But the Athenians answered as follows:

Neither are we beginning war, Peloponnesians, nor are we breaking the treaty; but these Corcyraeans are our allies, and we are come to help them. So if you want to sail anywhere else, we place no obstacle in your way; but if you are going to sail against Corcyra, or any of her possessions, we shall do our best to stop you.’
