History of the Peloponnesian War

When, however, Potidaea was being besieged, they did not remain quiet, as they had men in it, and were alarmed for the place. And immediately they summoned the allies to Lacedaemon, and came and cried out against the Athenians, as having broken the treaty, and as injuring the Peloponnese.

And the aeginetans, though they did not openly send ambassadors, for fear of the Athenians, yet in secret most of all urged on the war in conjunction with them, saying that they were not independent according to the treaty.

So the Lacedaemonians, after summoning any one of the allies besides, who said that in any other respect he had been injured by the Athenians, held their ordinary assembly, and told them to speak.
