History of the Peloponnesian War

The Lacedaemonians, after they had heard from all what they thought, put the question to the vote of all the allies who were present in succession, both to greater and smaller states alike: and the majority voted for war.

But though they had resolved on it, it was impossible to take it in hand immediately, as they were unprepared; but it was determined that suitable means should be provided by the several states, and that there should be no delay. A year, however, did not pass while they were settling all that was necessary, but less, before they invaded Attica, and openly proceeded to the war.
