The Athenians fled to the tract called Prosopitis, which was a a portion of the Delta, completely surrounded by two branch streams of the Nile.

Here they were besieged for eighteen months, till Megabyzus contrived to turn the water from one of the two streams, whereby the Athenian ships were stranded, and the Persian troops were able to march across the river bed, and overwhelm the Athenians with their numbers.

A few only escaped to Cyrene.

The entire fleet fell into the enemy's hands; and a reinforcement of fifty more ships, arriving soon after the defeat, was attacked unawares after it had entered the river, and lost more than half its number.

Inarus was betrayed by some of his own men, and, being carried prisoner to Persia, suffered death by crucifixion.
