The superiority of these troops arose from natural causes. The northern nations who invaded the empire consisted of a population trained from infancy to warlike exercises, and following no profession but that of arms. Their lands were cultivated by the labour of their slaves, or by that of the Roman subjects who still survived in the provinces they had occupied; but their only pecuniary resources arose from the plunder of their neighbours or the subsidies of the Roman emperors. Their habits of life, the celerity of their movements, and the excellence of their armour rendered them the choicest troops of the age; and their most active warriors were generally engaged to serve in the imperial forces. The emperors preferred armies composed of a number of motley bands of mercenary foreigners, attached to their own persons by high pay, and commanded by chiefs who could never pretend to political rank and who had much to lose and little to gain by rebellion; for experience proved that they perilled their throne by entrusting the command of a national army to a native general, who, from a popular soldier, might become a dangerous rival. Though the barbarian mercenaries in the service of Rome generally proved far more efficient troops than their free countrymen, yet they were on the whole unequal to the native Roman cavalry of Justinian’s army, the

Justinian weakened the Roman army in several ways by his measures of reform. His anxiety to reduce its expenditure induced him to diminish the establishment of camels, horses, and chariots, which attended the troops for transporting the military machines and baggage. This train had been previously very large, as it was calculated to save the peasantry from any danger of having their labours interrupted, or their cattle seized, under the pretext of being required for transport. Numerous abuses were introduced by diminishing the pay of the troops, and by neglecting to pay them with regularity and to furnish them with proper food and clothing. At the same time, the efficiency of the army in the field was more seriously injured by continuing the policy adopted by Anastasius, of restricting the power of the generals; a policy however which, it must be confessed, was not unnecessary in order to avoid greater evils. This is evident from the numerous rebellions in Justinian’s reign, and the absolute want of any national or patriotic feeling in the majority of the Roman officers.
Large armies were at times composed of a number of corps, each commanded by its own officer, over whom the nominal commander-in-chief had little or no authority; and it is to this circumstance that the unfortunate results of some of the Gothic and Persian campaigns are to be attributed, and not to any inferiority of the Roman troops. Even Belisarius himself, though he gave many proofs of attachment to Justinian’s throne, was watched with the greatest jealousy. He was treated with constant distrust, and his officers were at times encouraged to dispute his measures, and never punished for disobeying his orders. The fact is that Belisarius might, if so disposed, have assumed the purple, and perhaps dethroned his master. Narses was the only general who was implicitly trusted and steadily supported; but Narses was an aged eunuch, and could never have become emperor.
