History of the Peloponnesian War

Meanwhile Calligeitus and Timagoras did not join on behalf of Pharnabazus in the expedition to Chios or give the money—twenty-five talents—which they had brought with them to help in despatching a force, but determined to sail afterwards with another force by themselves.

Agis, on the other hand, seeing the Lacedaemonians bent upon going to Chios first, himself came in to their views; and the allies assembled at Corinth and held a council, in which they decided to sail first to Chios under the command of Chalcideus, who was equipping the five vessels in Laconia, then to Lesbos, under the command of Alcamenes, the same whom Agis had fixed upon, and lastly to go to the Hellespont, where the command was given to Clearchus, son of Ramphias.

Meanwhile they would take only half the ships across the Isthmus first, and let those sail off at once, in order that the Athenians might attend less to the departing squadron than to those to be taken across afterwards,

as no care had been taken to keep this voyage secret through contempt of the impotence of the Athenians, who had as yet no fleet of any account upon the sea. Agreeably to this determination twenty-one vessels were at once conveyed across the Isthmus.
