If a line of separation were drawn between the civilised and the savage climates of the globe, between the inhabitants of cities who cultivated the earth and the hunters and shepherds who dwelt in tents, Attila might aspire to the title of supreme and sole monarch of the barbarians. He alone, among the conquerors of ancient and modern times, united the two mighty kingdoms of Germany and Scythia; and those vague appellations, when they are applied to his reign, may be understood with an ample latitude. Thuringia, which stretched beyond its actual limits as far as the Danube, was in the number of his provinces; he interposed, with the weight of a powerful neighbour, in the domestic affairs of the Franks; and one of his lieutenants chastised, and almost exterminated, the Burgundians of the Rhine. He subdued the islands of the ocean, the kingdoms of Scandinavia, encompassed and divided by the waters of the Baltic; and the Huns might derive a tribute of furs from that northern region which has been protected from all other conquerors by the severity of the climate and the courage of the natives.
Towards the east it is difficult to circumscribe the dominion of Attila over the Scythian deserts; yet we may be assured that he reigned on the banks of the Volga; that the king of the Huns was dreaded, not only as a warrior, but as a magician; that he insulted and vanquished the khan of the formidable Geougen; and that he sent ambassadors to negotiate an equal alliance with the empire of China. In the proud review of the nations who acknowledged the sovereignty of Attila and who never entertained, during his lifetime, the thought of a revolt, the Gepidæ and the Ostrogoths were distinguished by their numbers, their bravery, and the personal merit of their chiefs.
The ambassadors of the Huns might awaken the attention of Theodosius by reminding him that they were his neighbours, both in Europe and Asia; since they touched the Danube on one hand, and reached with the other as far as the Tanais. In the reign of his father Arcadius, a band of adventurous Huns had ravaged the provinces of the East; from whence they brought away rich spoils and innumerable captives. They advanced, by a secret path, along the shores of the Caspian Sea; traversed the snowy mountains of Armenia; passed the Tigris, the Euphrates, and the Halys; recruited their weary cavalry with the generous breed of Cappadocian horses; occupied the hilly country of Cilicia, and disturbed the festal songs and dances of the citizens of Antioch. Egypt trembled at their approach; and the monks and pilgrims of the Holy Land prepared to escape their fury by a speedy embarkation. The memory of this invasion was still recent in the minds of the Orientals. The subjects of Attila might execute, with superior forces, the design which these adventurers had so boldly attempted; and it soon became the subject of anxious conjecture whether the tempest would fall on the dominions of Rome or of Persia.
Some of the great vassals of the king of the Huns, who were themselves in the rank of powerful princes, had been sent to ratify an alliance and society of arms with the emperor, or rather with the general, of the West. They related, during their residence at Rome, the circumstances of an expedition which they had lately made into the East. After passing a desert and a morass, supposed by the Romans to be the lake Mæotis, they penetrated through the mountains, and arrived at the end of fifteen days’ march on the confines of Media, where they advanced as far as the unknown cities of Basic and Cursic. They encountered the Persian army in the plains of Media; and the air, according to their own expression, was darkened by a cloud of arrows. But the Huns were obliged to retire before the numbers of the enemy. Their laborious retreat was effected by a different road; they lost the greatest part of their booty; and at length returned to the royal camp, with some knowledge of the country and an impatient desire for revenge.
[441-447 A.D.]
In the free conversation of the imperial ambassadors, who discussed at the court of Attila the character and designs of their formidable enemy, the ministers of Constantinople expressed their hope that his strength might be diverted and employed in a long and doubtful contest with the princes of the house of Sassan. The more sagacious Italians admonished their Eastern brethren of the folly and danger of such a hope, and convinced them that the Medes and Persians were incapable of resisting the arms of the Huns; and that the easy and important acquisition would exalt the pride as well as power of the conqueror. Instead of contenting himself with a moderate contribution and a military title, which equalled him only to the generals of Theodosius, Attila would proceed to impose a disgraceful and intolerable yoke on the necks of the prostrate and captive Romans, who would then be encompassed on all sides by the empire of the Huns.
While the powers of Europe and Asia were solicitous to avert the impending danger, the alliance of Attila maintained the Vandals in the possession of Africa. An enterprise had been concerted between the courts of Ravenna and Constantinople for the recovery of that valuable province; and the ports of Sicily were already filled with the military and naval forces of Theodosius. But the subtle Genseric, who spread his negotiations round the world, prevented their designs, by exciting the king of the Huns to invade the Eastern Empire; and a trifling incident soon became the motive, or pretence, of a destructive war.
Under the faith of the treaty of Margus, a free market was held on the northern side of the Danube, which was protected by a Roman fortress, surnamed Constantia. A troop of barbarians violated the commercial security; killed or dispersed the unsuspecting traders, and levelled the fortress with the ground. The Huns justified this outrage as an act of reprisal; alleged that the bishop of Margus had entered their territories, to discover and steal a secret treasure of their kings; and sternly demanded the guilty prelate, the sacrilegious spoil, and the fugitive subjects who had escaped from the justice of Attila. The refusal of the Byzantine court was the signal of war; and the Mœsians at first applauded the generous firmness of their sovereign. But they were soon intimidated by the destruction of Viminiacum and the adjacent towns; and the people was persuaded to adopt the convenient maxim that a private citizen, however innocent or respectable, may be justly sacrificed to the safety of his country. The bishop of Margus, who did not possess the spirit of a martyr, resolved to prevent the designs which he suspected. He boldly treated with the princes of the Huns; secured, by solemn oaths, his pardon and reward; posted a numerous detachment of barbarians in silent ambush on the banks of the Danube; and, at the appointed hour, opened with his own hand the gates of his episcopal city. This advantage, which had been obtained by treachery, served as a prelude to more honourable and decisive victories.
The Illyrian frontier was covered by a line of castles and fortresses; and though the greatest part of them consisted only of a single tower, with a small garrison, they were commonly sufficient to repel, or to intercept, the inroads of an enemy, who was ignorant of the art and impatient of the delay of a regular siege. But these slight obstacles were instantly swept away by the inundation of the Huns. They destroyed, with fire and sword, the populous cities of Sirmium and Singidunum, of Ratiaria and Marcianopolis, of Naissus and Sardica; where every circumstance of the discipline of the people and the construction of the buildings had been gradually adapted to the sole purpose of defence. The whole breadth of Europe, as it extends above five hundred miles from the Euxine to the Adriatic, was at once invaded, and occupied, and desolated, by the myriads of barbarians whom Attila led into the field. The public danger and distress could not, however, provoke Theodosius to interrupt his amusements and devotion, or to appear in person at the head of the Roman legions. But the troops which had been sent against Genseric were hastily recalled from Sicily, the garrisons on the side of Persia were exhausted; and a military force was collected in Europe, formidable by their arms and numbers, if the generals had understood the science of command and their soldiers the duty of obedience. The armies of the Eastern Empire were vanquished in three successive engagements; and the progress of Attila may be traced by the fields of battle. The two former, on the banks of the Utus and under the walls of Marcianopolis, were fought in the extensive plains between the Danube and Mount Hæmus. [In the latter battle Arnegisclus, the Roman commander, was slain.]
