The pastoral diligence of Anianus, a bishop of primitive sanctity and consummate prudence, exhausted every art of religious policy to support their courage till the arrival of the expected succours. After an obstinate siege, the walls were shaken by the battering-rams; the Huns had already occupied the suburbs; and the people who were incapable of bearing arms lay prostrate in prayer. Anianus, who anxiously counted the days and hours, despatched a trusty messenger to observe, from the rampart, the face of the distant country. He returned twice, without any intelligence that could inspire hope or comfort; but in his third report he mentioned a small cloud which he had faintly descried at the extremity of the horizon. “It is the aid of God!” exclaimed the bishop, in a tone of pious confidence; and the whole multitude repeated after him, “It is the aid of God!” The remote object, on which every eye was fixed, became each moment larger and more distinct; the Roman and Gothic banners were gradually perceived; and a favourable wind blowing aside the dust discovered, in deep array, the impatient squadrons of Aëtius and Theodoric, who pressed forward to the relief of Orleans.
The facility with which Attila had penetrated into the heart of Gaul may be ascribed to his insidious policy, as well as to the terror of his arms. His public declarations were skilfully mitigated by his private assurances; he alternately soothed and threatened the Romans and the Goths; and the courts of Ravenna and Tolosa, mutually suspicious of each other’s intentions, beheld with supine indifference the approach of their common enemy. Aëtius was the sole guardian of the public safety; but his wisest measures were embarrassed by a faction which, since the death of Placidia, infested the imperial palace; the youth of Italy trembled at the sound of the trumpet; and the barbarians, who, from fear or affection, were inclined to the cause of Attila, awaited with doubtful and venal faith the event of the war. The patrician passed the Alps at the head of some troops, whose strength and numbers scarcely deserved the name of an army. But on his arrival at Arelate, or Lugdunum he was confounded by the intelligence that the Visigoths, refusing to embrace the defence of Gaul, had determined to expect within their own territories the formidable invader whom they professed to despise.
The senator Avitus, who after the honourable exercise of the prætorian prefecture had retired to his estate in Auvergne, was persuaded to accept the important embassy, which he executed with ability and success. He represented to Theodoric that an ambitious conqueror, who aspired to the dominion of the earth, could be resisted only by the firm and unanimous alliance of the powers whom he laboured to oppress. The lively eloquence of Avitus inflamed the Gothic warriors by the description of the injuries which their ancestors had suffered from the Huns; whose implacable fury still pursued them from the Danube to the foot of the Pyrenees. He strenuously urged that it was the duty of every Christian to save from sacrilegious violation the churches of God and the relics of the saints; that it was the interest of every barbarian, who had acquired a settlement in Gaul, to defend the fields and vineyards which were cultivated for his use against the desolation of the Scythian shepherds. Theodoric yielded to the evidence of truth; adopted the measure at once the most prudent and the most honourable, and declared that, as the faithful ally of Aëtius and the Romans, he was ready to expose his life and kingdom for the common safety of Gaul.
The Visigoths, who at that time were in the mature vigour of their fame and power, obeyed with alacrity the signal of war; prepared their arms and horses, and assembled under the standard of their aged king, who was resolved with his two eldest sons Torismond and Theodoric, to command in person his numerous and valiant people. The example of the Goths determined several tribes or nations, that seemed to fluctuate between the Huns and the Romans. The indefatigable diligence of the patrician gradually collected the troops of Gaul and Germany, who had formerly acknowledged themselves the subjects, or soldiers, of the republic, but who now claimed the rewards of voluntary service and the rank of independent allies—the Læti, the Armoricans, the Breones, the Saxons, the Burgundiones, the Sarmatians or Alani, the Ripuarians, and the Franks who followed Meroveus as their lawful prince. Such was the various army which, under the conduct of Aëtius and Theodoric, advanced by rapid marches to relieve Orleans and to give battle to the innumerable host of Attila.
