8. Calligitus and Timagoras, who represented Pharnabazus, took no part in the expedition to Chios,¹ nor did they offer to contribute towards the expenses of it the money which they had brought with them, amounting to twenty-five talents²; they thought of sailing later with another expedition. [2] Agis, when he saw that the Lacedaemonians were bent on going to Chios first, offered no opposition; so the allies held a conference at Corinth, and after some deliberation determined to sail, first of all to Chios, under the command of Chalcideus, who was equipping the five ships in Laconia, then to proceed to Lesbos, under the command of Alcamenes, whom Agis had previously designed to appoint to that island, and finally to the Hellespont; for this last command they had selected Clearchus the son of Rhamphias. [3] They resolved to carry over the Isthmus half the ships first; these were to sail at once, that the attention of the Athenians might be distracted between those which were starting and those which were to follow. [4] They meant to sail quite openly, taking it for granted that the Athenians were powerless, since no navy of theirs worth speaking of had as yet appeared. In pursuance of their plans they conveyed twenty-one ships over the Isthmus.
