History of the Peloponnesian War

After ravaging the plain the Peloponnesians advanced into the Paralian region as far as Laurium, where the Athenian silver mines are, and first laid waste the side looking towards Peloponnese, next that which faces Euboea and Andros.

But Pericles, who was still general, held the same opinion as in the former invasion, and would not let the Athenians march out against them.

However while they were still in the plain, and had not yet entered the Paralian land, he had prepared an armament of a hundred ships for Peloponnese, and when all was ready put out to sea.

On board the ships he took four thousand Athenian heavy infantry, and three hundred cavalry in horse transports, then for the first time made out of old galleys; fifty Chian and Lesbian vessels also joining in the expedition.

When this Athenian armament put out to sea, they left the Peloponnesians in Attica in the Paralian region.
