History of the Peloponnesian War

This same man, pretending to have a quarrel which he had not yet avowed, and offering service to the chief men amongst them, had induced the Delians, who had settled at Atramyttium, when driven from their homes by the Athenians for the purpose of purifying Delos, to go out as though on terms of friendship and alliance with him; and then, having watched when they were at dinner, had surrounded them with his own troops, and shot them down.

Since therefore they were afraid, on account of this deed, that he might some time or other commit some outrage on themselves too, and since he also imposed upon them burdens which they could not bear, they expelled his garrison from their citadel.

When Tissaphernes heard of this act also on the part of the Peloponnesians, as well as that at Miletus and that at Cnidus, (for there too his garrisons had been driven out,) considering that he must have incurred their violent displeasure, and fearing that they might do him still further mischief, and, moreover, being vexed to think that Pharnabazus, by receiving them, might in less time and at less expense be more successful in his measures against the Athenians, he determined to go to them at the Hellespont, that he might both complain of what had been done at Antandrus, and defend himself as plausibly as he could against their charges respecting the Phoenician fleet, and all other matters. Accordingly he went first to Ephesus, and offered sacrifice to Diana.
