Events By place Byzantine Empire Byzantine–Sassanian War: A Persian expeditionary force under Shahrbaraz invades Egypt, and occupies the province. After defeating the Byzantine garrisons in the Nile Valley, the Persians march across the Libyan Desert as far as Cyrene. The Persians besiege Alexandria; the defence of the city is led by Nicetas (cousin of emperor Heraclius). The Byzantine resistance is undermined by a blockade of the harbor; the usual grain supplies are cut off from Egypt to Constantinople.
