In the tenth year[*](455 B.C.) the rebels on Ithome found that they could hold out no longer and surrendered to the Lacedaemonians on condition that they should leave the Peloponnesus under a truce and should never set foot in it again;
and if any of them should be caught there, he was to be a slave of his captor.
Moreover, before this time the Lacedaemonians also received a Pythian oracle, which bade them let go the suppliant of Ithomean Zeus. So the Messenians left the Peloponnesus, themselves and their children and wives; and the Athenians received them, in consequence of the enmity to the Lacedaemonians already existing, and settled them at Naupactus, which they happened to have lately taken from its possessors, the Ozolian Locrians.
And the Megarians also entered into alliance with the Athenians, revolting from the Lacedaemonians because the Corinthians were pressing them hard in a war about boundaries; and thus the Athenians secured Megara and Pegae,[*](Pegae was the Megarian harbour on the Corinthian gulf: Nisaea, a nearer one, on the Saronic gulf.) and they built for the Megarians the long walls which run from the city to Nisaea and held it with a garrison of their own troops. And it was chiefly because of this act that the vehement hatred of the Corinthians for the Athenians first arose.
Meanwhile Inaros, son of Psammetichus, a Libyan and king of the Libyans who are adjacent to Egypt, setting out from Mareia, the city just north of Pharos, caused the greater part of Egypt to revolt from King Artaxerxes,[*](460 B.C.) and then, when he had made himself ruler, he called in the Athenians.
And they left Cyprus,[*](cf. Thuc. 1.94.2.) where they happened to be on an expedition with two hundred ships of their own and of their allies, and went to Egypt, and when they had sailed up the Nile from the sea, finding themselves masters of the river and of twothirds of Memphis, they proceeded to attack the third part, which is called the White Fortress. And in this fortress were some Persians and Medes who had taken refuge there, and such Egyptians as had not joined in the revolt.
