Sasanian conquest of Egypt

Between 618 and 621 AD, the Sassanid Persian army defeated the Byzantine forces in Egypt and occupied the province. The fall of Alexandria, the capital of Roman Egypt, marked the first and most important stage in the Sassanid campaign to conquer this rich province, which eventually fell completely under Persian rule within a couple of years. A good account of the event is given by Butler.
