History of the Peloponnesian War

After the arrival of the men, the Athenians ordered that they should be kept in bonds till there should be made some agreement; and if before that the Peloponnesians should invade their territory, then to bring them forth and kill them.

They took order also [in the same assembly] for the settling of the garrison at Pylus. And the Messenians of Naupactus, having sent thither such men of their own as were fittest for the purpose, as to their native country (for Pylus is in that country which belonged once to the Messenians), infested Laconia with robberies and did them much other mischief, as being of the same language.
