History of the Peloponnesian War

This Arsaces, having feigned a certain war, not declared against whom, had formerly called out the chiefest of the Delians (the which in hallowing of Delos by the Athenians were turned out and had planted themselves in Adramyttium) to go with him to this war; and when under colour of amity and confederacy he had drawn them out, he observed a time when they were at dinner, and having hemmed them in with his own soldiers, murdered them with darts.

And therefore, for this act's sake fearing lest he might do some unlawful prank against them also, and for that he had otherwise done them injury, they cast his garrison out of their citadel.
