History of the Peloponnesian War

In the meantime it was decided by the Boeotarchs, the Corinthians, the Megarians, and the envoys from Thrace first to interchange oaths together to give help to each other whenever it was required and not to make war or peace except in common; after which the Boeotians and Megarians, who acted together, should make the alliance with Argos.

But before the oaths were taken the Boeotarchs communicated these proposals to the four councils of the Boeotians, in whom the supreme power resides, and advised them to interchange oaths with all such cities as should be willing to enter into a defensive league with the Boeotians.

But the members of the Boeotian councils refused their assent to the proposal, being afraid of offending Lacedaemon by entering into a league with the deserter Corinth; the Boeotarchs not having acquainted them with what had passed at Lacedaemon and with the advice given by Cleobulus and Xenares and the Boeotian partisans there, namely, that they should become allies of Corinth and Argos as a preliminary to a junction with Lacedaemon; fancying that, even if they should say nothing about this, the councils would not vote against what had been decided and advised by the Boeotarchs.

This difficulty arising, the Corinthians and the envoys from Thrace departed without anything having been concluded; and the Boeotarchs, who had previously intended after carrying this to try and effect the alliance with Argos, now omitted to bring the Argive question before the councils, or to send to Argos the envoys whom they had promised; and a general coldness and delay ensued in the matter.
