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.
Three years afterwards[*](451 B.C.) a truce was made between the Peloponnesians and Athenians, to last five years.
And the Athenians did abstain from warfare against Hellenes, but they made an expedition against Cyprus with two hundred ships of their own and of their allies, under the command of Cimon.
Sixty of these ships sailed to Egypt on the summons of Amyrtaeus, the king in the marshes, while the others laid siege to Citium.
But Cimon died and a famine arose, and so they withdrew from Citium ;[*](449 B.C.)and on their way home, when off Salamis in Cyprus, they fought the Phoenicians, Cyprians and Cilicians by sea and on land. Gaining the victory in both battles they went back home, and with them returned the ships that had been in Egypt.
After this the Lacedaemonians undertook the so-called sacred war, and getting possession of the temple at Delphi, delivered it to the Delphians; and afterwards, when they had withdrawn, the Athenians made an expedition, got possession of it, and delivered it again to the Phocians.
