But the most important condition of peace was understood rather than expressed in the treaty. Aurelian withdrew the Roman forces from Dacia, and tacitly relinquished that great province to the Goths and Vandals.[1030] His manly judgment convinced him of the solid advantages, and taught him to despise the seeming disgrace, of thus contracting the frontiers of the monarchy. The Dacian subjects, removed from those distant possessions which they were unable to cultivate or defend, added strength and populousness to the southern side of the Danube. A fertile territory, which the repetition of barbarous inroads had changed into a desert, was yielded to their industry, and a new province of Dacia still preserved the memory of Trajan's conquests. The old country of that name detained, however, a considerable number of its inhabitants, who dreaded exile more than a Gothic master.[1031] these degenerate romans continued to serve the empire, whose allegiance they had renounced, by introducing among their conquerors the first notions of agriculture, the useful arts, and the conveniences of civilized life. An intercourse of commerce and language was gradually established between the opposite banks of the Danube; and after Dacia became an independent state, it often proved the firmest barrier of the empire against the invasions of the savages of the North. A sense of interest attached these more settled barbarians to the alliance of Rome, and a permanent interest very frequently ripens into sincere and useful friendship. This various colony, which filled the ancient province, and was insensibly blended into one great people, still acknowledged the superior renown and authority of the Gothic tribe, and claimed the fancied honor of a Scandinavian origin. At the same time, the lucky though accidental resemblance of the name of Getae,[1032] infused among the credulous Goths a vain persuasion, that in a remote age, their own ancestors, already seated in the Dacian provinces, had received the instructions of Zamolxis, and checked the victorious arms of Sesostris and Darius.[1033]
While the vigorous and moderate conduct of Aurelian restored the Illyrian frontier, the nation of the Alemanni[1034] violated the conditions of peace, which either Gallienus had purchased, or Claudius had imposed, and, inflamed by their impatient youth, suddenly flew to arms. Forty thousand horse appeared in the field,[1035] and the numbers of the infantry doubled those of the cavalry,[1036] the first objects of their avarice were a few cities of the Rhaetian frontier; but their hopes soon rising with success, the rapid march of the Alemanni traced a line of devastation from the Danube to the Po.[1037]
The emperor was almost at the same time informed of the irruption, and of the retreat, of the barbarians. Collecting an active body of troops, he marched with silence and celerity along the skirts of the Hercynian forest; and the Alemanni, laden with the spoils of Italy, arrived at the Danube, without suspecting, that on the opposite bank, and in an advantageous post, a Roman army lay concealed and prepared to intercept their return. Aurelian indulged the fatal security of the barbarians, and permitted about half their forces to pass the river without disturbance and without precaution. Their situation and astonishment gave him an easy victory; his skilful conduct improved the advantage. Disposing the legions in a semicircular form, he advanced the two horns of the crescent across the Danube, and wheeling them on a sudden towards the centre, enclosed the rear of the German host. The dismayed barbarians, on whatsoever side they cast their eyes, beheld, with despair, a wasted country, a deep and rapid stream, a victorious and implacable enemy.
Reduced to this distressed condition, the Alemanni no longer disdained to sue for peace. Aurelian received their ambassadors at the head of his camp, and with every circumstance of martial pomp that could display the greatness and discipline of Rome. The legions stood to their arms in well-ordered ranks and awful silence. The principal commanders, distinguished by the ensigns of their rank, appeared on horseback on either side of the Imperial throne. Behind the throne the consecrated images of the emperor, and his predecessors,[1038] the golden eagles, and the various titles of the legions, engraved in letters of gold, were exalted in the air on lofty pikes covered with silver. When Aurelian assumed his seat, his manly grace and majestic figure[1039] taught the barbarians to revere the person as well as the purple of their conqueror. The ambassadors fell prostrate on the ground in silence. They were commanded to rise, and permitted to speak. By the assistance of interpreters they extenuated their perfidy, magnified their exploits, expatiated on the vicissitudes of fortune and the advantages of peace, and, with an ill-timed confidence, demanded a large subsidy, as the price of the alliance which they offered to the Romans. The answer of the emperor was stern and imperious. He treated their offer with contempt, and their demand with indignation, reproached the barbarians, that they were as ignorant of the arts of war as of the laws of peace, and finally dismissed them with the choice only of submitting to this unconditional mercy, or awaiting the utmost severity of his resentment.[1040] Aurelian had resigned a distant province to the Goths; but it was dangerous to trust or to pardon these perfidious barbarians, whose formidable power kept Italy itself in perpetual alarms.
Immediately after this conference, it should seem that some unexpected emergency required the emperor's presence in Pannonia.
He devolved on his lieutenants the care of finishing the destruction of the Alemanni, either by the sword, or by the surer operation of famine. But an active despair has often triumphed over the indolent assurance of success. The barbarians, finding it impossible to traverse the Danube and the Roman camp, broke through the posts in their rear, which were more feebly or less carefully guarded; and with incredible diligence, but by a different road, returned towards the mountains of Italy.[1041] Aurelian, who considered the war as totally extinguished, received the mortifying intelligence of the escape of the Alemanni, and of the ravage which they already committed in the territory of Milan. The legions were commanded to follow, with as much expedition as those heavy bodies were capable of exerting, the rapid flight of an enemy whose infantry and cavalry moved with almost equal swiftness. A few days afterwards, the emperor himself marched to the relief of Italy, at the head of a chosen body of auxiliaries, (among whom were the hostages and cavalry of the Vandals,) and of all the Praetorian guards who had served in the wars on the Danube.[1042]
As the light troops of the Alemanni had spread themselves from the Alps to the Apennine, the incessant vigilance of Aurelian and his officers was exercised in the discovery, the attack, and the pursuit of the numerous detachments. Notwithstanding this desultory war, three considerable battles are mentioned, in which the principal force of both armies was obstinately engaged.[1043] the success was various. in the first, fought near Placentia, the Romans received so severe a blow, that, according to the expression of a writer extremely partial to Aurelian, the immediate dissolution of the empire was apprehended,[1044] the crafty barbarians, who had lined the woods, suddenly attacked the legions in the dusk of the evening, and, it is most probable, after the fatigue and disorder of a long march.

The Walachians still preserve many traces of the Latin language and have boasted, in every age, of their Roman descent. They are surrounded by, but not mixed with, the barbarians. See a Memoir of M. d'Anville on ancient Dacia, in the Academy of Inscriptions, tom. xxx.

The connection between the Getae and the Goths is still in my opinion incorrectly maintained by some learned writers-M.

See the first chapter of Jornandes. The Vandals, however, (c. 22,) maintained a short independence between the Rivers Marisia and Crissia, (Maros and Keres,) which fell into the Teiss.

Cantoclarus, with his usual accuracy, chooses to translate three hundred thousand: his version is equally repugnant to sense and to grammar.
1036
We may remark, as an instance of bad taste, that Dexippus applies to the light infantry of the Alemanni the technical terms proper only to the Grecian phalanx.

In Dexippus, we at present read Rhodanus: M. de Valois very judiciously alters the word to Eridanus.

The emperor Claudius was certainly of the number; but we are ignorant how far this mark of respect was extended; if to Caesar and Augustus, it must have produced a very awful spectacle; a long line of the masters of the world.
