At the Hellespont, Mindarus had been reinforced after the battle of Kynossêma by the squadron from Eubœa, at least by that portion of it which had escaped the storm off Mount Athos. The departure of the Peloponnesian fleet from Eubœa enabled the Athenians also to send a few more ships to their fleet at Sestos. Thus ranged on the opposite sides of the strait, the two fleets came to a second action, wherein the Peloponnesians, under Agesandridas, had the advantage; yet with little fruit. It was about the month of October, seemingly, that Dorieus with his fourteen triremes came from Rhodes to rejoin Mindarus at the Hellespont. He had hoped probably to get up the strait to Abydos during the night, but he was caught by daylight a little way from the entrance, near Rhœteium; and the Athenian scouts instantly gave signal of his approach. Twenty Athenian triremes were despatched to attack him: upon which Dorieus fled, and sought safety by hauling his vessel ashore in the receding bay near Dardanus. The Athenian squadron here attacked him, but were repulsed and forced to sail back to Madytus. Mindarus was himself a spectator of this scene, from a distance; being engaged in sacrificing to Athênê, on the venerated hill of Ilium. He immediately hastened to Abydos, where he fitted out his whole fleet of eighty-four triremes, Pharnabazus coöperating on the shore with his land-force. Having rescued the ships of Dorieus, his next care was to resist the entire Athenian fleet, which presently came to attack him under Thrasybulus and Thrasyllus. An obstinate naval combat took place between the two fleets, which lasted nearly the whole day with doubtful issue; at length, towards the evening, twenty fresh triremes were seen approaching. They proved to be the squadron of Alkibiadês sailing from Samos: having probably heard of the rejunction of the squadron of Dorieus with the main Peloponnesian fleet, he had come with his own counter-balancing reinforcement.[162] As soon as his purple flag or signal was ascertained, the Athenian fleet became animated with redoubled spirit. The new-comers aided them in pressing the action so vigorously, that the Peloponnesian fleet was driven back to Abydos, and there run ashore. Here the Athenians still followed up their success, and endeavored to tow them all off. But the Persian land-force protected them, and Pharnabazus himself was seen foremost in the combat; even pushing into the water in person, as far as his horse could stand. The main Peloponnesian fleet was thus preserved; yet the Athenians retired with an important victory, carrying off thirty triremes as prizes, and retaking those which they had themselves lost in the two preceding actions.[163] [162] Diodorus (xiii, 46) and Plutarch (Alkib. c. 27) speak of his coming to the Hellespont by accident, κατὰ τύχην, which is certainly very improbable.
