At the beginning of the next summer the Chians were urging that the fleet should be sent off, being afraid that the Athenians, from whom all these embassies were kept a secret, might find out what was going on, and the Lacedaemonians at once sent three Spartans to Corinth to haul the ships as quickly as possible across the Isthmus from the other sea to that on the side of Athens, and to order them all to sail to Chios, those which Agis was equipping for Lesbos not excepted.

The number of ships from the allied states was thirty-nine in all.
