It is with still greater injustice that the ruin of the prosperity of Gaul and Spain in the period immediately following the expedition of Radagaisus has been attributed to him as a crime. Stilicho had brought the Roman troops from Gaul and kept them with him after the liberation of Italy, as he intended seeking out the Goths in Illyricum. The barbarians in Germany seized this opportunity to invade Gaul (407). The Quadi, Vandals, Suevi, Alani, Heruli, Saxons, Burgundiones, Franks, and other barbarians broke into the unfortunate country, wasting it as they advanced, whilst the Gepidæ, Sarmatæ, and Huns pressed into the Danubian provinces which some of these peoples had hitherto occupied, and settled there. Argentoratum (Strasburg), Noviomagus (Speier), Borbetomagus (Worms), Mogontiacum, and other towns, which until then had opposed a barrier to the barbarians, were destroyed, and like a rushing stream the invaders poured themselves over all parts of Gaul.
The like misfortune overtook the province of Britain, whence Stilicho had just recalled the Roman forces. In 407 the troops of this country, amongst whom there were only a few Roman soldiers, finding themselves thus abandoned to their fate, proclaimed one of their number, Constantine, emperor, and under his leadership crossed over into Gaul. Here Constantine was universally acknowledged as ruler by the inhabitants, who stood in much need of help. An army under the general Sarus, whom Honorius sent against him, was beaten, and Constantine also fought the barbarians successfully. As, owing to the gravity of the situation in Italy and Gaul, Honorius and his ministers could not for the moment concern themselves with Spain, Constantine considered the moment propitious to subject that country also. The religious dissensions by which Spain as well as Africa was then rent, and the persecutions which the Donatists and Arians had to suffer from the orthodox Honorius and his court ecclesiastics, facilitated Constantine’s undertaking. The Roman troops and militia were vanquished by him and almost the whole land conquered. Unfortunately Constantine replaced the brave national militia of the mountaineers, who until then had defended the passes of the Pyrenees, by mercenaries of all nations, and these shortly after made common cause with the barbarians who wandered across the mountains from Gaul, and became their companions and guides.
Zosimus
Zosimus does not hesitate to say that as his trust made him minister of justice it was necessary to buy it from him either with money or with favour; that “all the best and richest lands in the empire fell into his hands either through fear of incurring his disfavour or in the desire to lean upon his reputation to pillage the people; that he acquired immense riches by despoiling the most illustrious families and ruining the provinces.” One reads the same thing, and written in a more odious manner, in Suidas,
