That questionable shape such glory wore
That mortals quail'd beneath him."
Two chiefs of the Franks, who were then settled on the Lower Rhine, were at this period engaged in a feud with each other, and while one of them appealed to the Romans for aid, the other invoked the assistance and protection of the Huns. Attila thus obtained an ally whose coöperation secured for him the passage of the Rhine, and it was this circumstance which caused him to take a northward route from Hungary for his attack upon Gaul. The muster of the Hunnish hosts was swollen by warriors of every tribe that they had subjugated; nor is there any reason to suspect the old chroniclers of wilful exaggeration in estimating Attila's army as seven hundred thousand strong. Having crossed the Rhine probably a little below Coblentz, he defeated the king of the Burgundians, who endeavored to bar his progress. He then divided his vast forces into two armies, one of which marched northwest upon Tongres and Arras and the other cities of that part of France, while the main body, under Attila himself, advanced up the Moselle, and destroyed Besançon and other towns in the country of the Burgundians.
One of the latest and best biographers of Attila well observes that, "having thus conquered the eastern part of France, Attila prepared for an invasion of the West-Gothic territories beyond the Loire. He marched upon Orleans, where he intended to force the passage of that river, and only a little attention is requisite to enable us to perceive that he proceeded on a systematic plan: he had his right wing on the north for the protection of his Frank allies; his left wing on the south for the purpose of preventing the Burgundians from rallying and of menacing the passes of the Alps from Italy; and he led his centre toward the chief object of the campaign—the conquest of Orleans, and an easy passage into the West-Gothic dominion. The whole plan is very like that of the allied powers in 1814, with this difference, that their left wing entered France through the defiles of the Jura, in the direction of Lyons, and that the military object of the campaign was the capture of Paris."
It was not until the year 451 that the Huns commenced the siege of Orleans; and during their campaign in Eastern Gaul, the Roman general Aetius had strenuously exerted himself in collecting and organizing such an army as might, when united to the soldiery of the Visigoths, be fit to face the Huns in the field. He enlisted every subject of the Roman Empire whom patriotism, courage, or compulsion could collect beneath the standards; and round these troops, which assumed the once proud title of the legions of Rome he arrayed the large forces of barbaric auxiliaries, whom pay, persuasion, or the general hate and dread of the Huns brought to the camp of the last of the Roman generals. King Theodoric exerted himself with equal energy. Orleans resisted her besiegers bravely as in after-times. The passage of the Loire was skilfully defended against the Huns; and Aetius and Theodoric, after much manoeuvring and difficulty, effected a junction of their armies to the south of that important river.
On the advance of the allies upon Orleans, Attila instantly broke up the siege of that city and retreated toward the Marne. He did not choose to risk a decisive battle with only the central corps of his army against the combined power of his enemies, and he therefore fell back upon his base of operations, calling in his wings from Arras and Besançon, and concentrating the whole of the Hunnish forces on the vast plains of Châlons-sur-Marne. A glance at the map will show how scientifically this place was chosen by the Hunnish general as the point for his scattered forces to converge upon; and the nature of the ground was eminently favorable for the operations of cavalry, the arm in which Attila's strength peculiarly lay.
It was during the retreat from Orleans that a Christian hermit is reported to have approached the Hunnish King and said to him, "Thou art the Scourge of God for the chastisement of the Christians." Attila instantly assumed this new title of terror, which thenceforth became the appellation by which he was most widely and most fearfully known.
The confederate armies of Romans and Visigoths at last met their great adversary face to face on the ample battleground of the Châlons plains. Aetius commanded on the right of the allies; King Theodoric on the left; and Sangipan, King of the Alans, whose fidelity was suspected, was placed purposely in the centre, and in the very front of the battle. Attila commanded his centre in person, at the head of his own countrymen, while the Ostrogoths, the Gepidæ, and the other subject allies of the Huns were drawn up on the wings.
Some manoeuvring appears to have occurred before the engagement, in which Aetius had the advantage, inasmuch as he succeeded in occupying a sloping hill which commanded the left flank of the Huns. Attila saw the importance of the position taken by Aetius on the high ground, and commenced the battle by a furious attack on this part of the Roman line, in which he seems to have detached some of his best troops from his centre to aid his left. The Romans, having the advantage of the ground, repulsed the Huns, and while the allies gained this advantage on their right, their left, under King Theodoric, assailed the Ostrogoths, who formed the right of Attila's army. The gallant King was himself struck down by a javelin as he rode onward at the head of his men; and his own cavalry, charging over him, trampled him to death in the confusion. But the Visigoths, infuriated, not dispirited, by their monarch's fall, routed the enemies opposed to them, and then wheeled upon the flank of the Hunnish centre, which had been engaged in a sanguinary and indecisive contest with the Alans.
In this peril Attila made his centre fall back upon his camp; and when the shelter of its intrenchments and wagons had once been gained, the Hunnish archers repulsed, without difficulty, the charges of the vengeful Gothic cavalry. Aetius had not pressed the advantage which he gained on his side of the field, and when night fell over the wild scene of havoc Attila's left was still undefeated, but his right had been routed and his centre forced back upon his camp.
