Philippic 3

Now it was not at Olynthus only that this habit produced every kind of evil result; but at Eretria, when the democrats, ridding themselves of Plutarchus and his mercenaries, held the city together with Porthmus, some of them were for handing the government over to you, others to Philip. The latter on most points, or rather on all, gained the ear of the sorely tried and ill-starred Eretrians, and at last persuaded them to expel their real champions.

For of course Philip, whom they fancied their ally, sent Hipponicus with a thousand mercenaries, razed the walls of Porthmus, and set up three tyrants, Hipparchus, Automedon, and Clitarchus. Twice since then they have tried to deliver themselves, and twice he has driven them from their homes on the first occasion sending Eurylochus with his mercenaries, on the second Parmenio.

And what need is there to mention most of the cases? But at Oreus Philistides, Menippus, Socrates, Thoas, and Agapaeus, the very men who now control the city, were, as everyone knew, Philip’s agents, but Euphraeus, a man who once resided here at Athens, was working for the freedom and emancipation of his countrymen.

It would be a long story to tell you how this man was repeatedly outraged and insulted by the people; but a year before the capture of Eretria, detecting the machinations of Philistides and his party, he denounced him as a traitor. Then a number of fellows banded together, with Philip for their paymaster and managing director, and dragged Euphraeus off to prison for setting the city in an uproar.
