Sarbar, the general of the third army, penetrated through the provinces of Asia to the well-known camp of Chalcedon, and amused himself with the destruction of the sacred and profane buildings of the Asiatic suburbs, while he impatiently waited the arrival of his Scythian friends on the opposite side of the Bosphorus. On the twenty-ninth of June, thirty thousand Barbarians, the vanguard of the Avars, forced the long wall, and drove into the capital a promiscuous crowd of peasants, citizens, and soldiers.
