History of the Peloponnesian War

In this manner spake the Mytilenaeans. And the Lacedaemonians and their confederates, when they had heard and allowed their reasons, decreed not only a league with the Lesbians but also again to make an invasion into Attica. And to that purpose the Lacedaemonians appointed their confederates there present to make as much speed as they could with two parts of their forces into the isthmus; and they themselves being first there prepared engines in the isthmus for the drawing up of galleys, with intention to carry the navy from Corinth to the other sea that lieth towards Athens, and to set upon them both by sea and land.

And these things diligently did they. But the rest of the confederates assembled but slowly, being busied in the gathering in of their fruits and weary of warfare.

The Athenians, perceiving all this preparation to be made upon an opinion of their weakness and desirous to let them see they were deceived as being able, without stirring the fleet at Lesbos, easily to master the fleet that should come against them out of Peloponnesus, manned out a hundred galleys and embarked therein generally, both citizens (except those of the degree of Pentacosiomedimni and Horsemen) and also strangers that dwelt amongst them, and sailing to the isthmus made a show of their strength and landed their soldiers in such parts of Peloponnesus as they thought fit.

When the Lacedaemonians saw things so contrary to their expectation, they thought it false which was spoken by the Lesbian ambassadors, and esteeming the action difficult, seeing their confederates were not arrived and that news was brought of the wasting of the territory near their city by the thirty galleys formerly sent about Peloponnesus by the Athenians, went home again,

and afterwards prepared to send a fleet to Lesbos, and intimated to the cities rateably to furnish forty galleys, and appointed Alcidas, who was to go thither with them, for admiral.
