History of the Peloponnesian War

All this while the Athenians stayed still in Egypt and saw much variety of war. First the Athenians were masters of Egypt;

and the king of Persia sent one Megabazus, a Persian, with money to Lacedaemon to procure the Peloponnesians to invade Attica, and by that means to draw the Athenians out of Egypt.

But when this took no effect, and money was spent to no purpose, Megabazus returned with the money he had left into Asia.

And then was Megabazus the son of Zopyrus, a Persian, sent into Egypt with great forces, and coming in by land overthrew the Egyptians and their confederates in a battle, drave the Grecians out of Memphis, and finally inclosed them in the isle of Prosopis. There he besieged them a year and a half, till such time as having drained the channel and turned the water another way, he made their galleys lie aground and the island for the most part continent, and so came over and won the island with land soldiers.
