Aureolus was soon obliged to surrender, and he was put to death by the soldiers. An army of Alamanni, coming perhaps to his aid, was then, it is said, defeated by Claudius near Verona. After his victory the emperor proceeded to Rome, where during the remainder of the year he devoted his time and thoughts to the reformation of abuses in the state. Among other just and prudent regulations, he directed that the properties confiscated by Gallienus should be restored to their original owners. A woman, it is said, came on this occasion to the emperor and claimed her land, which she said had been given to Claudius, the commander of the cavalry. This officer was the emperor himself, and he replied that the emperor Claudius must restore what he took when he was a private man and less bound to obey the laws.
The following year (269) the Goths and their allies embarked, we are told, to the number of 320,000 warriors, with their wives, children, and slaves, in two or, as some say, six thousand vessels, and directed their course to the Bosporus. In passing that narrow channel the number of their vessels and the rapidity of the current caused them to suffer considerable loss. Their attempts on Byzantium and Cyzicus having failed, they proceeded along the northern coast of the Ægean, and laid siege to the cities of Cassandrea and Thessalonica. While thus engaged they learned that the emperor was on his march to oppose them, and breaking up they advanced into the interior, wasting and plundering the country on their way. Near the town of Naisus, in Dardania, they encountered the Roman legions. The battle was long and bloody, and the Romans were at one time on the verge of defeat; but the skill of Claudius turned the beam, and the Goths were finally routed with a loss of fifty thousand men. During the remainder of the year numerous desultory actions occurred, in which the Goths sustained great losses; and being finally hemmed in on all sides by the Roman troops, they were forced to seek refuge in Mount Hæmus, and pass the winter amidst its snows. Famine and pestilence alike preyed on them, and when on the return of spring (270) the emperor took the field against them, they were obliged to surrender at discretion. A portion of their youth were enrolled in the imperial troops; vast numbers both of men and women were reduced to slavery; on some lands were bestowed in the provinces; few returned to their seats on the Euxine.
The pestilence which had afflicted the Goths proved also fatal to the emperor. He was attacked and carried off by it at Sirmium in the fifty-seventh year of his age. In the presence of his principal officers he named, it is said, Aurelian, one of his generals, as the fittest person to succeed him; but his brother Quintilius, when he heard of his death, assumed the purple at Aquileia, and was acknowledged by the senate. Hearing, however, that Aurelian was on his march against him, he gave up all hopes of success, and opening his veins died after a reign of seventeen days.
Aurelian (L. Domitius Aurelianus), 270-275 A.D.
Aurelian, like his able predecessor, was a man of humble birth. His father is said to have been a small farmer, and his mother a priestess of the Sun, in a village near Sirmium. He entered the army as a common soldier, and rose through the successive gradations of the service to the rank of general of a frontier. He was adopted in the presence of Valerian (some said at his request) by Ulpius Crinitus, a senator of the same family with the emperor Trajan, who gave him his daughter in marriage, and Valerian bestowed on him the office of consul. In the Gothic War Claudius had committed to him the command of the cavalry.
Immediately on his election Aurelian hastened to Rome, whence he was speedily recalled to Pannonia by the intelligence of an irruption of the Goths. A great battle was fought, which was terminated by night without any decisive advantage on either side. Next day the Goths retired over the river and sent proposals of peace, which was cheerfully accorded, and for many years no hostilities of any account occurred between the Goths and Romans. But while Aurelian was thus occupied in Pannonia, the Alamanni, with a force of forty thousand horse and eighty thousand foot, had passed the Alps and spread their ravages to the Po. Instead of following them into Italy, Aurelian, learning that they were on their return home with their booty, marched along the Danube to intercept their retreat, and attacking them unawares, he reduced them to such straits that they sent to sue for peace.
