And the Lacedaemonians also sent with him eleven Spartans to act as advisers to Astyochus, one of whom was Lichas son of Arcesilaus. Their orders were, on arriving at Miletus, to share with Astyochus the general oversight of affairs in whatever way would be for the best, and also to send this fleet, with either the same number of ships or more or fewer, to Pharnabazus in the Hellespont, should this course seem expedient, appointing as its commander Clearchus[*](cf. 8.8.2.) son of Ramphias, who was sailing with them; also, if it should seem best, to depose Astyochus from his office as admiral and put Antisthenes in his stead; for in view of the letter of Pedaritus they were suspicious of him.
Accordingly these ships, sailing from Malea across the open sea, touched at Melos, and falling in with ten Athenian ships captured three of them, but without their crews, and burned them. After this, fearing that the Athenian ships that had escaped from Melos might, as actually happened, inform the Athenians at Samos of their approach, they sailed toward Crete, making the voyage longer as a measure of precaution, and put in at Caunus in Asia.
From there, feeling that they were now in security, they sent a message to the ships at Miletus with a view to being convoyed along the coast.
