The History of the Grecian War (1.103.4-1.104.2)

The Megareans also revolted from the Lacedaemonians and came to the league of the Athenians because they were holden down by the Corinthians with a war about the limits of their territories. Whereupon Megara and Pegae were put into the hands of the Athenians, who built for the Megareans the long walls from the city to Nisaea and maintained them with a garrison of their own. And from hence it was chiefly that the vehement hatred grew of the Corinthians against the Athenians.

Moreover Inarus, the son of Psammetticus, an African, king of the Africans that confine on Egypt, making war from Mareia above Pharus, caused the greatest part of Egypt to rebel against the king Artaxerxes;

and when he had taken the government of them upon himself, he brought in the Athenians to assist him, who chancing to be then warring on Cyprus with two hundred galleys, part their own and part their confederates, left Cyprus and went to him. And going from the sea up the river of Nilus after they had made themselves masters of the river and of two parts of the city of Memphis, assaulted the third part called the White Wall. Within were of the Medes and Persians, such as had escaped, and of the Egyptians, such as had not revolted amongst the rest.
