History of the Peloponnesian War

"Such was the part we were proud to play in the great actions of the past. It was not until later that we became your enemies, and for this you yourselves were to blame; for when the Thebans oppressed us and we sought alliance with you, you rebuffed us and bade us apply to the Athenians, because they were near, whereas you lived far away.

In the course of this war, however, you have neither suffered, nor were ever in danger of suffering, any extraordinary harm at our hands.

And if we refused to revolt from the Athenians at your bidding, we were not in the wrong; for they helped us against the Thebans when you held back. After that it would not have been honourable for us to desert them, above all when we were their debtors and when at our own request we had been admitted to their alliance and had shared the rights of citizenship with them. On the contrary, there was every reason why we should heartily obey their commands.

And whatever measures either you or they have initiated for your allies, it is not the followers who are to blame for any wrong that has been done, but those who have led them into evil courses.
