The fate of the doomed city drew on. Pestilence was added to the calamities which the besieged had to endure. Desertion and treachery were arrayed against them. One of the natives of Amida, going over to the Persians, informed them that on the southern side of the city a neglected staircase led up from the margin of the Tigris through underground corridors to one of the principal bastions; and under his guidance seventy archers of the Persian guard, picked men, ascended the dark passage at dead of night, occupied the tower, and when morning broke displayed from it a scarlet flag, as a sign to their countrymen that a portion of the wall was taken. The Persians were upon the alert, and an instant assault was made. But the garrison, by extraordinary efforts, succeeded in recapturing the tower before any support reached its occupants; and then, directing their artillery and missiles against the assailing columns, inflicted on them tremendous losses, and soon compelled them to return hastily to the shelter of their camp. The Verte, who maintained the siege on the south side of the city, were the chief sufferers in this abortive attempt. Sapor had now spent seventy days before the place, and had made no perceptible impression. Autumn was already far advanced, and the season for military operations would, soon be over. It was necessary, therefore, either to take the city speedily or to give up the siege and retire. Under these circumstances Sapor resolved on a last effort. He had constructed towers of such a height that they overtopped the wall, and poured their discharges on the defenders from a superior elevation. He had brought his mounds in places to a level with the ramparts, and had compelled the garrison to raise countermounds within the walls for their protection. He now determined on pressing the assault day after day, until he either carried the town or found all his resources exhausted. His artillery, his foot, and his elephants were all employed in turn or together; he allowed the garrison no rest. Not content with directing the operations, he himself took part in the supreme struggle, exposing his own person freely to the enemy’s weapons, and losing many of his attendants. After the contest had lasted three continuous days from morn to night, fortune at last favored him. One of the inner mounds, raised by the besieged behind their wall, suddenly gave way, involving its defenders in its fall, and at the same time filling up the entire space between the wall and the mound raised outside by the Persians. A way into the town was thus laid open, and the besiegers instantly occupied it. It was in vain that the flower of the garrison threw itself across the path of the entering columns--nothing could withstand the ardor of the Persian troops. In a little time all resistance was at an end; those who could quitted the city and fled--the remainder, whatever their sex, age, or calling, whether armed or
