White Wall

Thoſe who eſcaped fled to Memphis, whither the conquerors purſued them, and immediately made themſelves maſters of two quarters or diviſions of the city: but the Perſians having fortified themſelves in the third, called the white wall, which was the largeſt and the ſtrongest of the three; they were beſeiged in it near three years, during which they made a moſt vigorous defence, till they were at laſt delivered by the forces that were ſent to their ſuccour.
