History of the Peloponnesian War

In the beginning of winter (for now there were other ephores in office; not those in whose time the peace was made, but some of them that opposed it), ambassadors being come from the confederates, and the Athenian, Boeotian, and Corinthian ambassadors being [already] there, and having had much conference together but concluded nothing, Cleobulus and 36enares, ephores that most desired the dissolution of the peace, when the rest of the ambassadors were gone home, entered into private conference with the Boeotians and Corinthians, exhorting them to run both the same course; and advised the Boeotians to endeavour first to make a league themselves with the Argives and then to get the Argives together with themselves into a league with the Lacedaemonians, for that they might by this means avoid the necessity of accepting the peace with Athens; for the Lacedaemonians would more regard the friendship and league of the Argives than the enmity and dissolution of the peace with the Athenians; for they knew the Lacedaemonians had ever desired to have Argos their friend upon any reasonable conditions, because they knew that their war without Peloponnesus would thereby be a great deal the easier.

Wherefore they entreated the Boeotians to put Panactum into the hands of the Lacedaemonians, to the end that, if they could get Pylus for it in exchange, they might make war against the Athenians the more commodiously.
