History of the Peloponnesian War

At his return, when the Athenians understood that nothing was effected at Lacedaemon, they grew presently into choler; and apprehending injury (the Argives and their confederates being there present, brought in by Alcibiades), they made a peace and a league with them in these words:

"The Athenians and Argives and Mantineans and Eleians, for themselves and for the confederates commanded by every of them, have made an accord for one hundred years, without fraud or damage, both by sea and land.

It shall not be lawful for the Argives nor Eleians nor Mantineans nor their confederates to bear arms against the Athenians or the confederates under the command of the Athenians or their confederates by any fraud or machination whatsoever. "And the Athenians, Argives, and Mantineans have made league with each other for one hundred years on these terms:

"If any enemy shall invade the territory of the Athenians, then the Argives, Eleians, and Mantineans shall go unto Athens to assist them, according as the Athenians shall send them word to do, in the best manner they possibly can. But if the enemy, after he have spoiled the territory, shall be gone back, then their city shall be held as an enemy to the Argives, Eleians, Mantineans, and Athenians, and war shall be made against it by all those cities; and it shall not be lawful for any of those cities to give over the war without the consent of all the rest. "And if an enemy shall invade the territory, either of the Argives or of the Eleians or of the Mantineans, then the Athenians shall come unto Argos, Elis, and Mantineia to assist them, in such sort as those cities shall send them word to do, in the best manner they possibly can.
