Meanwhile Tissaphernês, having completed his measures in Ionia, arrived at the Hellespont not long after the battle of Abydos, seemingly about November, 411 B.C. He was anxious to regain some credit with the Peloponnesians, for which an opportunity soon presented itself. Alkibiadês, then in command of the Athenian fleet at Sestos, came to visit him in all the pride of victory, bringing the customary presents; but the satrap seized his person and sent him away to Sardis as a prisoner in custody, affirming that he had the Great King’s express orders for carrying on war with the Athenians.[167] Here was an end of all the delusions of Alkibiadês, respecting pretended power of influencing the Persian counsels. Yet these delusions had already served his purpose by procuring for him a renewed position in the Athenian camp, which his own military energy enabled him to sustain and justify. [167] Xenoph. Hellen. i, 1, 9; Plutarch, Alkibiadês, c. 27. Towards the middle of this winter the superiority of the fleet of Mindarus at Abydos, over the Athenian fleet at Sestos, had become so great,—partly, as it would appear, through reinforcements obtained by the former, partly through the dispersion of the latter into flying squadrons from want of pay,—that the Athenians no longer dared to maintain their position in the Hellespont. They sailed round the southern point of the Chersonese, and took station at Kardia, on the western side of the isthmus of that peninsula. Here, about the commencement of spring, they were rejoined by Alkibiadês; who had found means to escape from Sardis, along with Mantitheus, another Athenian prisoner, first to Klazomenæ, and next to Lesbos, where he collected a small squadron of five triremes. The dispersed squadrons of the Athenian fleet being now all summoned to concentrate, Theramenês came to Kardia from Macedonia, and Thrasybulus from Thasos; whereby the Athenian fleet was rendered superior in number to that of Mindarus. News was brought that the latter had moved with his fleet from the Hellespont to Kyzikus, and was now engaged in the siege of that place, jointly with Pharnabazus and the Persian land-force. His vigorous attacks had in fact already carried the place, when the Athenian admirals resolved to attack him there, and contrived to do it by surprise. Having passed first from Kardia to Elæûs at the south of the Chersonese, they sailed up the Hellespont to Prokonnesus by night, so that their passage escaped the notice of the Peloponnesian guardships at Abydos.[168] [168] Diodor. xiii, 49. Diodorus specially notices this fact, which must obviously be correct. Without it, the surprise of Mindarus could not have been accomplished.
