Among the generals who had greatly distinguished themselves in the Syrian wars was Amrou, destined to be the conqueror of Egypt; for the khalifs, not content with their victories on the North and East, now turned their eyes to the West, and prepared for the annexation of Africa. As in the former cases, so in this, sectarian treason assisted them. The Saracen army was hailed as the deliverer of the Jacobite Church; the Monophysite Christians of Egypt, that is, they who, in the language of the Athanasian Creed, confounded the substance of the Son, proclaimed, through their leader, Mokaukas, that they desired no communion with the Greeks, either in this world or the next, that they abjured forever the Byzantine tyrant and his synod of Chalcedon. They hastened to pay tribute to the khalif, to repair the roads and bridges, and to supply provisions and intelligence to the invading army. FALL OF ALEXANDRIA. Memphis, one of the old Pharaonic capitals, soon fell, and Alexandria was invested. The open sea behind gave opportunity to Heraclius to reenforce the garrison continually. On his part, Omar, who was now khalif sent to the succor of the besieging army the veteran troops of Syria. There were many assaults and many sallies. In one Amrou himself was taken prisoner by the besieged, but, through the dexterity of a slave, made his escape. After a siege of fourteen months, and a loss of twenty-three thousand men, the Saracens captured the city. In his dispatch to the Khalif, Amrou enumerated the splendors of the great city of the West "its four thousand palaces, four thousand baths, four hundred theatres, twelve thousand shops for the sale of vegetable food, and forty thousand tributary Jews." So fell the second great city of Christendom--the fate of Jerusalem had fallen on Alexandria, the city of Athanasius, and Arius, and Cyril; the city that had imposed Trinitarian ideas and Mariolatry on the Church. In his palace at Constantinople Heraclius received the fatal tidings. He was overwhelmed with grief. It seemed as if his reign was to be disgraced by the downfall of Christianity. He lived scarcely a month after the loss of the town. But if Alexandria had been essential to Constantinople in the supply of orthodox faith, she was also essential in the supply of daily food. Egypt was the granary of the Byzantines. For this reason two attempts were made by powerful fleets and armies for the recovery of the place, and twice had Amrou to renew his conquest. He saw with what facility these attacks could be made, the place being open to the sea; he saw that there was but one and that a fatal remedy. "By the living God, if this thing be repeated a third time I will make Alexandria as open to anybody as is the house of a prostitute!" He was better than his word, for he forthwith dismantled its fortifications, and made it an untenable place.
