So, when the Thebans had failed in their attempt and the Plataeans had put to death those of their number whom they had taken alive in the battle, the Lacedaemonians, without waiting now for any pretext, marched against Plataea. They ordered all the Peloponnesians with the exception of the Argives to send two-thirds of their armies from their several cities, and they sent word to all the rest of the Boeotians and the Locrians and Phocians and Malians and Oetaeans and Aenians to take the field with their entire forces. All the states mentioned were in central Greece, and belonged to the Peloponnesian confederacy.
