This endangered the authority of the Romans, especially in Italy. Alexander, who was sent thither as commissioner, unhesitatingly reproached the soldiers for this. He also exacted large sums of money from the Italians, under the pretence of punishing them for their negotiations with Theoderic and the Goths. The soldiers were not the only persons who were reduced to poverty and privation by the commissioners; but those who had accompanied the generals in different capacities and had formerly enjoyed a high reputation, found themselves in great distress, as they had no means of procuring the ordinary necessaries. Since I am speaking of the soldiers, I will give a few additional details. Preceding Emperors had, for a very long time past, carefully posted upon all the frontiers of the Empire a large military force to protect its boundaries, and particularly, in the Eastern provinces, in order to repel the inroads of the Persians and Saracens, they had established garrisons called "frontier troops." Justinian at first treated these troops with such shameful neglect that their pay was four, or even five years in arrear; and, when peace was concluded between Rome and Persia, these unhappy individuals, who expected to enjoy the advantages of peace, were obliged to make a present to the treasury of the money due to them; and the Emperor finally disbanded them most unjustly. Thus the frontiers of the Roman Empire remained ungarrisoned, and the troops had nothing to subsist upon except the benevolence of the charitable.
