The answer came--at the same time with an imperial letter from Byzantium--on a day which was equally pregnant with the fate of the heroes both in and out of Ravenna. CHAPTER XVI. Hildebad, impatient at the long pause of idleness, had, one day at dawn, made a sudden sally upon the Byzantines from the Porta Faventina, which was under his special command. He had at first won great advantages, had burnt a portion of the enemies' implements of siege, and had spread terror all around. He would, without doubt, have done still more mischief had not Belisarius, hurrying up, displayed at once all his heroism and generalship. Without helmet or armour, just as he had hurried from his tent, he had first checked his own flying outposts, and had then thrown himself upon the Gothic pursuers, and by the utmost personal exertion had brought the fight to a standstill. Afterwards he had man[oe]uvred his two flanks so cleverly, that Hildebad's retreat was greatly endangered, and the Goths were obliged to retreat speedily into the city. Cethegus, who lay encamped before the Porta Honorius with his Isaurians, had found, on hastening to the assistance of Belisarius, that the fight was already over. He could not, therefore, avoid paying a visit to the commander-in-chief in his tent, in order to express his admiration of the heroes conduct, both as a general and a soldier; praise which was greedily listened to by Antonina. "Really, Belisarius," concluded the Prefect, "Emperor Justinian can never requite your valour sufficiently." "There you speak truly," answered Belisarius haughtily; "he can only requite me by his friendship. The mere honour of bearing his marshal's staff would never have induced me to do that which I have already done, and shall yet accomplish. I do it only because I really love him. With all his failings, he is a great man. If he could but learn one thing--to trust me! But patience--he will learn it in time." Just then Procopius entered, bringing a letter for Belisarius, which had been delivered by an imperial messenger. With a countenance beaming with delight, Belisarius, forgetting his fatigue, sprang from his cushions, kissed the letter, and with his dagger cut the purple cord which tied it. He unfolded the paper with the words: "From my Emperor himself! Ah, now he will send me the gold and the rest of the body-guard!" And he began to read. Antonina, Procopius, and Cethegus observed him attentively. His features grew darker and darker; his broad chest began to heave; both the hands with which he held the letter trembled. Antonina anxiously approached him, but before she could question him, Belisarius uttered a low cry of rage, cast the letter on the ground, and rushed madly out of the tent. His wife followed him.
