History of the Peloponnesian War

When the business at Plataea had occurred, and the treaty had been clearly broken, the Athenians began to prepare for going to war; and so did the Lacedaemonians and their allies, both intending to send embassies to the king, and to the barbarians in other parts, from whatever quarter either party hoped to gain any assistance, and bringing into alliance with them such states as were not in their power.

And [*]( For the construction of this obscure sentence see Arnold's note) on the side of the Lacedaemonians, in addition to the ships already on the spot in Sicily and Italy, belonging to those who had espoused their cause, they were ordered to build more according to the greatness of the cities, so that in the whole number they should amount to five hundred; and to get ready a certain sum of money which was mentioned, while they remained quiet in other respects, and received the Athenians coming with a single ship, till these preparations should be made.

The Athenians, on the other hand, were inspecting their present confederacy, and sending ambassadors to the countries more immediately around the Peloponnese, as Corcyra, Cephallenia, Acarnania, and Zacynthus; seeing that if these were firm friends to them, they would successfully carry on the war round the Peloponnese.
