History of the Peloponnesian War

And these, though satisfied, stayed behind at first, but afterwards they also went, and sitting down before Orchomenus, jointly besieged and assaulted the same, desiring to take it in as well for other causes as chiefly for that the hostages which the Arcadians had given to the Lacedaemonians were there in custody.

The Orchomenians, fearing the weakness of their walls, and the greatness of the army, and lest they should perish before any relief could arrive, yielded up the town on conditions to be received into the league, give hostages for themselves, and to surrender the hostages held there by the Lacedaemonians into the hands of the Mantineans.

The confederates after this, having gotten Orchomenus, sat in council about what town they should proceed against next. The Eleians gave advice to go against Lepreum, but the Mantineans against Tegea. And the Argives and Athenians concurred in opinion with the Mantineans.

But the Eleians, taking it in evil part that they did not decree to go against Lepreum, went home. But the rest prepared themselves at Mantineia to go against Tegea, which also some within had a purpose to put into their hands.
