XXXVII But before we set forth the order of the 194 battle itself, it seems needful to relate what had already happened in the course of the campaign, for it was not only a famous struggle but one that was complicated and confused. Well then, Sangiban, king of the Alani, smitten with fear of what might come to pass, had promised to surrender to Attila, and to give into his keeping Aureliani, a city of Gaul wherein he then dwelt. When Theodorid 195 and Aëtius learned of this, they cast up great earthworks around that city before Attila's arrival and kept watch over the suspected Sangiban, placing him with his tribe in the midst of their auxiliaries. Then Attila, king of the Huns, was taken aback by this event and lost confidence in his own troops, so that he feared to begin the conflict. While he was meditating on flight--a greater calamity than death itself--he decided to inquire into the future through soothsayers. So, as was their custom, 196 they examined the entrails of cattle and certain streaks in bones that had been scraped, and foretold disaster to the Huns. Yet as a slight consolation they prophesied that the chief commander of the foe they were to meet should fall and mar by his death the rest of the victory and the triumph. Now Attila deemed the death of Aëtius a thing to be desired even at the cost of his own life, for Aëtius stood in the way of his plans. So although he was disturbed by this prophecy, yet inasmuch as he was a man who sought counsel of omens in all warfare, he began the battle with anxious heart at about the ninth hour of the day, in order that the impending darkness might come to his aid if the outcome should be disastrous.
