History of the Peloponnesian War

When Agis saw that the Lacedaemonians meant to send first to Chios, he resolved not of any other course himself; but the confederates assembling at Corinth went to council upon the matter and concluded thus: that they should go first to Chios under the command of Chalcideus, who was making ready the five galleys at Laconia; and then to Lesbos under the charge of Alcamenes, intended also to be sent thither by Agis; and lastly into Hellespont, in which voyage they ordained that Clearchus, the son of Rhamphias, should have the command;

and concluded to carry over the isthmus first the one half of their galleys, and that those should presently put to sea, that the Athenians might have their minds more upon those than on the other half to be transported afterwards.

For they determined to pass that sea openly, contemning the weakness of the Athenians in respect they had not any navy of importance yet appearing. As they resolved, so presently they carried over one-and-twenty galleys.
