But while they were still in their territory the Athenians sent out on an expedition round the Peloponnesus the hundred ships[*](2.17.4.) which they had been equipping, and on them a thousand hoplites and four hundred archers; and the generals in command were Carcinus son of Xenotimus, Proteas son of Epicles, and Socrates son of Antigenes.

So they set sail with this force and began their cruise; the Peloponnesians, on the other hand, remained in Attica for as long a time as they were provisioned and then withdrew through Boeotia, taking a different route from that by which they had entered Attica. They passed by Oropus and laid waste the district called Graice,[*](Named after the ancient town of Γραῖα (Hom. Il. 2.498).) which the Oropians occupy as subjects of the Athenians.[*](This was written before 412/11, when Oropus was captured by the Boeotians.) Then on their return to the Peloponnesus they were dismissed to their several cities.
