The Decline and Fall of the Roman Empire · Chapter 25 (10/11)

The Goths had contracted an hereditary attachment for the Imperial house of Constantine, of whose power and liberality they had received so many signal proofs. AD 366 They respected the public peace; and if a hostile band sometimes presumed to pass the Roman limit, their irregular conduct was candidly ascribed to the ungovernable spirit of the Barbarian youth. Their contempt for two new and obscure princes, who had been raised to the throne by a popular election, inspired the Goths with bolder hopes; and, while they agitated some design of marching their confederate force under the national standard,3202 they were easily tempted to embrace the party of Procopius, and to foment, by their dangerous aid, the civil discord of the Romans. The public treaty might stipulate no more than ten thousand auxiliaries; but the design was so zealously adopted by the chiefs of the Visigoths that the army which passed the Danube amounted to the number of thirty thousand men.3203 They marched with the proud confidence that their invincible valor would decide the fate of the Roman empire; and the provinces of Thrace groaned under the weight of the Barbarians, who displayed the insolence of masters and the licentiousness of enemies. But the intemperance which gratified their appetites retarded their progress; and before the Goths could receive any certain intelligence of the defeat and death of Procopius, they perceived, by the hostile state of the country, that the civil and military powers were resumed by his successful rival. A chain of posts and fortifications, skilfully disposed by Valens, or the generals of Valens, resisted their march, prevented their retreat, and intercepted their subsistence. The fierceness of the Barbarians was tamed and suspended by hunger; they indignantly threw down their arms at the feet of the conqueror, who offered them food and chains: the numerous captives were distributed in all the cities of the East; and the provincials, who were soon familiarized with their savage appearance, ventured, by degrees, to measure their own strength with these formidable adversaries, whose name had so long been the object of their terror. The king of Scythia (and Hermanric alone could deserve so lofty a title) was grieved and exasperated by this national calamity. His ambassadors loudly complained, at the court of Valens, of the infraction of the ancient and solemn alliance which had so long subsisted between the Romans and the Goths. They alleged that they had fulfilled the duty of allies by assisting the kinsman and successor of the emperor Julian; they required the immediate restitution of the noble captives; and they urged a very singular claim that the Gothic generals, marching in arms and in hostile array, were entitled to the sacred character and privileges of ambassadors. The decent but peremptory refusal of these extravagant demands was signified to the Barbarians by Victor, master-general of the cavalry; who expressed, with force and dignity, the just complaints of the emperor of the East.3204 The negotiation was interrupted; and the manly exhortations of Valentinian encouraged his timid brother to vindicate the insulted majesty of the empire.3205

The splendor and magnitude of this Gothic war are celebrated by a contemporary historian;3206 but the events scarcely deserve the attention of posterity, except as the preliminary steps of the approaching decline and fall of the empire. AD 367⁠–⁠369 Instead of leading the nations of Germany and Scythia to the banks of the Danube, or even to the gates of Constantinople, the aged monarch of the Goths resigned to the brave Athanaric the danger and glory of a defensive war, against an enemy who wielded with a feeble hand the powers of a mighty state. A bridge of boats was established upon the Danube; the presence of Valens animated his troops; and his ignorance of the art of war was compensated by personal bravery and a wise deference to the advice of Victor and Arintheus, his masters-general of the cavalry and infantry. The operations of the campaign were conducted by their skill and experience; but they found it impossible to drive the Visigoths from their strong posts in the mountains; and the devastation of the plains obliged the Romans themselves to repass the Danube on the approach of winter. The incessant rains, which swelled the waters of the river, produced a tacit suspension of arms, and confined the emperor Valens, during the whole course of the ensuing summer, to his camp of Marcianopolis. The third year of the war was more favorable to the Romans, and more pernicious to the Goths. The interruption of trade deprived the Barbarians of the objects of luxury which they already confounded with the necessaries of life; and the desolation of a very extensive tract of country threatened them with the horrors of famine. Athanaric was provoked, or compelled, to risk a battle, which he lost, in the plains; and the pursuit was rendered more bloody by the cruel precaution of the victorious generals, who had promised a large reward for the head of every Goth that was brought into the Imperial camp. The submission of the Barbarians appeased the resentment of Valens and his council: the emperor listened with satisfaction to the flattering and eloquent remonstrance of the senate of Constantinople, which assumed, for the first time, a share in the public deliberations; and the same generals, Victor and Arintheus, who had successfully directed the conduct of the war, were empowered to regulate the conditions of peace. The freedom of trade, which the Goths had hitherto enjoyed, was restricted to two cities on the Danube; the rashness of their leaders was severely punished by the suppression of their pensions and subsidies; and the exception, which was stipulated in favor of Athanaric alone, was more advantageous than honorable to the Judge of the Visigoths. Athanaric, who, on this occasion, appears to have consulted his private interest, without expecting the orders of his sovereign, supported his own dignity, and that of his tribe, in the personal interview which was proposed by the ministers of Valens. He persisted in his declaration that it was impossible for him, without incurring the guilt of perjury, ever to set his foot on the territory of the empire; and it is more than probable that his regard for the sanctity of an oath was confirmed by the recent and fatal examples of Roman treachery. The Danube, which separated the dominions of the two independent nations, was chosen for the scene of the conference. The emperor of the East and the Judge of the Visigoths, accompanied by an equal number of armed followers, advanced in their respective barges to the middle of the stream. After the ratification of the treaty, and the delivery of hostages, Valens returned in triumph to Constantinople; and the Goths remained in a state of tranquillity about six years; till they were violently impelled against the Roman empire by an innumerable host of Scythians, who appeared to issue from the frozen regions of the North.3207

The emperor of the West, who had resigned to his brother the command of the Lower Danube, reserved for his immediate care the defence of the Rhaetian and Illyrian provinces, which spread so many hundred miles along the greatest of the European rivers. The active policy of Valentinian was continually employed in adding new fortifications to the security of the frontier; but the abuse of this policy provoked the just resentment of the Barbarians. AD 374 The Quadi complained that the ground for an intended fortress had been marked out on their territories; and their complaints were urged with so much reason and moderation that Equitius, master-general of Illyricum, consented to suspend the prosecution of the work, till he should be more clearly informed of the will of his sovereign. This fair occasion of injuring a rival, and of advancing the fortune of his son, was eagerly embraced by the inhuman Maximin, the prefect, or rather tyrant, of Gaul. The passions of Valentinian were impatient of control; and he credulously listened to the assurances of his favorite that, if the government of Valeria, and the direction of the work, were entrusted to the zeal of his son Marcellinus, the emperor should no longer be importuned with the audacious remonstrances of the Barbarians. The subjects of Rome, and the natives of Germany, were insulted by the arrogance of a young and worthless minister, who considered his rapid elevation as the proof and reward of his superior merit. He affected, however, to receive the modest application of Gabinius, king of the Quadi, with some attention and regard; but this artful civility concealed a dark and bloody design, and the credulous prince was persuaded to accept the pressing invitation of Marcellinus. I am at a loss how to vary the narrative of similar crimes; or how to relate that, in the course of the same year, but in remote parts of the empire, the inhospitable table of two Imperial generals was stained with the royal blood of two guests and allies, inhumanly murdered by their order and in their presence. The fate of Gabinius and of Para was the same: but the cruel death of their sovereign was resented in a very different manner by the servile temper of the Armenians and the free and daring spirit of the Germans. The Quadi were much declined from that formidable power which, in the time of Marcus Antoninus, had spread terror to the gates of Rome. But they still possessed arms and courage; their courage was animated by despair, and they obtained the usual reinforcement of the cavalry of their Sarmatian allies. So improvident was the assassin Marcellinus that he chose the moment when the bravest veterans had been drawn away to suppress the revolt of Firmus; and the whole province was exposed, with a very feeble defence, to the rage of the exasperated Barbarians. They invaded Pannonia in the season of harvest; unmercifully destroyed every object of plunder which they could not easily transport; and either disregarded or demolished the empty fortifications. The princess Constantia, the daughter of the emperor Constantius and the granddaughter of the great Constantine, very narrowly escaped. That royal maid, who had innocently supported the revolt of Procopius, was now the destined wife of the heir of the Western empire. She traversed the peaceful province with a splendid and unarmed train. Her person was saved from danger, and the republic from disgrace, by the active zeal of Messala, governor of the provinces. As soon as he was informed that the village, where she stopped only to dine, was almost encompassed by the Barbarians, he hastily placed her in his own chariot, and drove full speed till he reached the gates of Sirmium, which were at the distance of six and twenty miles. Even Sirmium might not have been secure if the Quadi and Sarmatians had diligently advanced during the general consternation of the magistrates and people. Their delay allowed Probus, the Praetorian prefect, sufficient time to recover his own spirits and to revive the courage of the citizens. He skilfully directed their strenuous efforts to repair and strengthen the decayed fortifications; and procured the seasonable and effectual assistance of a company of archers to protect the capital of the Illyrian provinces. Disappointed in their attempts against the walls of Sirmium, the indignant Barbarians turned their arms against the master-general of the frontier, to whom they unjustly attributed the murder of their king. Equitius could bring into the field no more than two legions; but they contained the veteran strength of the Maesian and Pannonian bands. The obstinacy with which they disputed the vain honors of rank and precedency was the cause of their destruction; and while they acted with separate forces and divided councils, they were surprised and slaughtered by the active vigor of the Sarmatian horse. The success of this invasion provoked the emulation of the bordering tribes; and the province of Maesia would infallibly have been lost, if young Theodosius, the duke, or military commander, of the frontier, had not signalized, in the defeat of the public enemy, an intrepid genius worthy of his illustrious father and of his future greatness.3208
