It is probable that the crafty Aetius was unwilling to be too victorious. He dreaded the glory which his allies the Visigoths had acquired, and feared that Rome might find a second Alaric in Prince Torismund, who had signalized himself in the battle, and had been chosen on the field to succeed his father Theodoric. He persuaded the young King to return at once to his capital, and thus relieved himself at the same time of the presence of a dangerous friend as well as of a formidable though beaten foe. Attila's attacks on the Western Empire were soon renewed, but never with such peril to the civilized world as had menaced it before his defeat at Chalons; and on his death, two years after that battle, the vast empire which his genius had founded was soon dissevered by the successful revolts of the subject nations. The name of the Huns ceased for some centuries to inspire terror in Western Europe, and their ascendency passed away with the life of the great King by whom it had been so fearfully augmented.[25] EDWARD GIBBON 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 Toulouse, mutually suspicious of each other's intentions, beheld with supine indifference the approach of their common enemy. Aetius 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 Aries, or Lyons, 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.
