The reason for this was that after the Vandals were defeated, Justinian planned, not how he might best strengthen his hold on the country, nor how by safeguarding the interests of those who were loyal to him he might have the goodwill of his subjects: but instead he foolishly recalled Belisarius at once, on the charge that the latter intended to make himself King (an idea of which Belisarius was utterly incapable), and so that he might manage affairs there himself and be able to plunder the whole of Libya.
Sending commissioners to value the province, he imposed grievous taxes where before there had been none. Whatever lands were most valuable, he seized, and prohibited the Arians from observing their religious ceremonies. Negligent toward sending necessary supplies to the soldiers, he was over-strict with them in other ways; wherefore mutinies arose resulting in the deaths of many. For he was never able to abide by established customs, but naturally threw everything into confusion and disturbance.
Italy, which is not less than thrice as large as Libya, was everywhere desolated of men, even worse than the other country; and from this the count of those who perished there may be imagined. The reason for what happened in Italy I have already made plain. All of his crimes in Libya were repeated here; sending his auditors to Italy, he soon upset and ruined everything.
City of Sirmium
The rule of the Goths, before this war, had extended from the land of the Gauls to the boundaries of Dacia, where the city of Sirmium is. The Germans held Cisalpine Gaul and most of the land of the Venetians, when the Roman army arrived in Italy. Sirmium and the neighboring country was in the hands of the Gepidae. All of these he utterly depopulated. For those who did not die in battle perished of disease and famine, which as usual followed in the train of war.
Illyria and all of Thrace, that is, from the Ionian Gulf to the suburbs of Constantinople, including Greece and the Chersonese, were overrun by the Huns, Slavs and Antes, almost every year, from the time when Justinian took over the Roman Empire; and intolerable things they did to the inhabitants. For in each of these incursions, I should say, more than two hundred thousand Romans were slain or enslaved, so that all this country became a desert like that of Scythia.
