History of the Peloponnesian War

Thus spoke the Mytilenaeans. The Lacedaemonians and their allies, after they had heard them, accepted their proposals, and received the Lesbians as allies. Those allies who were there present were directed to assemble with all speed at the Isthmus with two-thirds[*](cf. 2.10.2.) of their forces for the purpose of making the proposed invasion of Attica; and the Lacedaemonians themselves arrived first and proceeded to construct on the Isthmus hauling-machines with which to transfer the ships from Corinth to the sea on the Athenian side, in order to attack Athens both by sea and by land.

They set to work zealously at these things, but the rest of the allies collected slowly, since they were busy gathering in their harvest and were in no mood for campaigning.
