History of the Peloponnesian War

And now Orestes son of Echecratidas, king of the Thessalians, who was exiled from Thessaly, persuaded the Athenians to restore him. And they, taking along some Boeotians and Phocians who were allies, made an expedition against Pharsalus in Thessaly. And though they made themselves masters of the land, so far as this was possible without going far from their camp—for the Thessalian cavalry hemmed them in—they failed to capture the city and indeed none of the other objects of their expedition was attained, so they went back home again unsuccessful, having Orestes with them.

Not long after this[*](454 B.C.) one thousand Athenians, embarking on the ships at Pegae, which was now in their possession,[*](cf. Thuc. 1.103.4.) sailed along the coast to Sicyon under the command of Pericles son of Xanthippus, and disembarking defeated in battle the Sicyonians who came out against them.

Immediately thereafter, taking along some Achaeans and sailing across the gulf, they made an expedition against Oeniadae in Acarnania and laid siege to it; but failing to take it they went back home.
