72,) who has enriched the conquest of Egypt with
some facts from the Arabic text of Severus the Jacobite historian]

By the retreat of the Greeks from the provinces of Upper Egypt, a
considerable force was collected in the Island of Delta; the natural
and artificial channels of the Nile afforded a succession of strong and
defensible posts; and the road to Alexandria was laboriously cleared by
the victory of the Saracens in two-and-twenty days of general or partial
combat. In their annals of conquest, the siege of Alexandria [111] is
perhaps the most arduous and important enterprise. The first trading
city in the world was abundantly replenished with the means of
subsistence and defence. Her numerous inhabitants fought for the dearest
of human rights, religion and property; and the enmity of the natives
seemed to exclude them from the common benefit of peace and toleration.
The sea was continually open; and if Heraclius had been awake to the
public distress, fresh armies of Romans and Barbarians might have been
poured into the harbor to save the second capital of the empire. A
circumference of ten miles would have scattered the forces of the
Greeks, and favored the stratagems of an active enemy; but the two sides
of an oblong square were covered by the sea and the Lake Maraeotis, and
each of the narrow ends exposed a front of no more than ten furlongs.
The efforts of the Arabs were not inadequate to the difficulty of the
attempt and the value of the prize. From the throne of Medina, the eyes
of Omar were fixed on the camp and city: his voice excited to arms the
Arabian tribes and the veterans of Syria; and the merit of a holy war
was recommended by the peculiar fame and fertility of Egypt. Anxious
for the ruin or expulsion of their tyrants, the faithful natives devoted
their labors to the service of Amrou: some sparks of martial spirit were
perhaps rekindled by the example of their allies; and the sanguine
hopes of Mokawkas had fixed his sepulchre in the church of St. John of
Alexandria. Eutychius the patriarch observes, that the Saracens fought
with the courage of lions: they repulsed the frequent and almost daily
sallies of the besieged, and soon assaulted in their turn the walls and
towers of the city. In every attack, the sword, the banner of Amrou,
glittered in the van of the Moslems. On a memorable day, he was betrayed
by his imprudent valor: his followers who had entered the citadel
were driven back; and the genera
