After his demise Vithimiris was made king and resisted the Halani for a time, relying on other Huns, whom he had paid to take his side. But after many defeats which he sustained, he was overcome by force of arms and died in battle. In the name of his little son, Viderichus, the management of affairs was undertaken by Alatheus and Saphrax, experienced generals known for their courage; but since the stress of circumstances compelled them to abandon confidence in resistance, they cautiously retreated until they came to the river Danastius,[*](Also called the Tyras, to-day the Dniester.) which flows through the wide extent of plain between the Hister and the Borysthenes.[*](To-day the Dnieper.)
On learning of these unexpected events, Athanarichus, the chief of the Theruingi (against whom, as has been told before,[*](Cf. xxvii. 5, 6.) because of aid which he had sent to Procopius, Valens had recently taken the field) attempted to stand his ground, and if he too should be attacked like the rest, was ready to put forth all his strength.
Accordingly, he established his camp near the banks of the Danastius, conveniently at some distance from the stockade of the Greuthungi, and sent Munderichus, afterwards in charge of the frontier throughout Arabia, with Lagarimanus and some other men of high rank, to a distance of twenty miles in advance, to observe
But the result was far other than he expected. For the Huns, who are shrewd in arriving at conclusions, suspecting that there was some large force farther off, disregarded the troops which they had seen, and who had disposed themselves to rest, as if there was nothing to disturb them; then, when the moon broke into the darkness of night, they chose what seemed to be the best course, crossed the river by a ford, and fearing lest some informer should get ahead of them and frighten off the enemy who were at a distance, they made a swift attack on Athanaricus himself.
As he was stunned by their first onset, they forced him to take speedy refuge in the steep mountains, after losing a few of their own men. Athanaricus, troubled[*](Cf. cura constrictus, xx, 4, 19.) by this unexpected attack and still more through fear of what might come, had walls built high, skirting the lands of the Taifali from the banks of the river Gerasus[*](To-day the Pruth on the eastern frontier of ancient Dacia.) as far as the Danube, thinking that by this hastily but diligently constructed barrier[*](For lorica in this sense, cf. 15, 4, below.) his security and safety would be assured.
