History of the Peloponnesian War

Demosthenes, in the mean time, stayed behind, and made preparations for the expedition, intending to start as soon as it was spring; while he sent the allies word to levy troops, and got ready at home money, ships, and heavy-armed.

The Athenians also sent twenty ships to cruise round the Peloponnese, and to keep guard that none might cross over from Corinth and the Peloponnese to Sicily.
