), succeeded Melancridas as Lacedaemonian high admiral, in the summer of 412, B. C., the year after the Syracusan defeat, and arrived with four ships at Chios, late in the summer. (Thuc. 8.20
.) Lesbos was now the seat of the contest : and his arrival was followed by the recovery to the Athenians of the whole island. (Ib. 23.) Astyochus was eager for a second attempt; but compelled, by the refusal of the Chians and their Spartan captain, Pedaritus, to forego it, he proceeded, with many threats of revenge, to take the general command at Miletus. (31-33.) Here he renewed the Persian treaty, and remained, notwithstanding the entreaties of Chios, then hard pressed by the Athenians, wholly inactive.
He was at last starting to relieve it, when he was called off, about mid-winter, to join a fleet from home, bringing, in consequence of complaints from Pedaritus, commissioners to examine his proceedings.
Before this (έ̀τι ὄντα τότε περὶ Μίλητον
, cc. 36-42), Astyochus it appears had sold himself to the Persian interest.
He had received, perhaps on first coming to Miletus, orders from home to put Alcibiades to death; but finding him in refuge with the satrap Tissaphernes, he not only gave up all thought of the attempt, but on receiving private intelligence of his Athenian negotiations, went up to Magnesia, betrayed Phrynichus his informant to Alcibiades, and there, it would seem, pledged himself to the satrap. (cc. 45 and 50.) Henceforward, in pursuance of his patron's policy, his efforts were employed in keeping his large forces inactive, and inducing submission to the reduction in their Persian pay.
The acquisition of Rhodes, after his junction with the new fleet, he had probably little to do with; while to him, must, no doubt, be ascribed the neglect of the opportunities afforded by the Athenian dissensions, after his return to Miletus (cc. 60 and 63), 411 B. C.
The discontent of the troops, especially of the Syracusans, was great, and broke out at last in a riot, where his life was endangered; shortly after which his successor Mindarus arrived, and Astyochus sailed home (cc. 84, 85), after a command of about eight months. Upon his return to Sparta he bore testimony to the truth of the charges which Hermocrates, the Syracusan, brought against Tissaphernes. (Xen. Hell. 1.1.31
