History of the Peloponnesian War

After executing these measures, and placing a governor in Cos, it being now towards autumn, he sailed back to Samos. As for Tissaphernes, when he heard that the Peloponnesian squadron had sailed from Miletus to the Hellespont, he set out again from Aspendus, and proceeded to Ionia.

Now while the Peloponnesians were in the Hellespont, the Antandrians, (of Aeolian extraction,) conveyed by land over Mount Ida some heavy-armed troops from Abydus, and introduced them into their city, in consequence of being ill-treated by Arsaces the Persian, Tissaphernes' lieutenant.
