The victorious armies of Justinian were therefore composed of two distinct elements, the foreign auxiliaries serving under their own chiefs, and the regular imperial troops. The pages of Procopius give us sufficient evidence that in both these divisions the cavalry was by far the most important arm. The light horseman of the Asiatic provinces wins his especial praise. With body and limbs clothed in mail, his quiver at his right side and his sword at his left, the Roman trooper would gallop along and discharge his arrows to front or flank or rear with equal ease. To support him marched in the second line the heavier squadrons of the subsidized Lombard, or Herule, or Gepidan princes, armed with the lance. ‘There are some,’ writes Procopius, ‘who regard antiquity with wonder and respect, and attach no special worth to our modern military institutions: it is, however, by means of the latter that the weightiest and most striking results have been obtained.’ The men of the sixth century were, in fact, entirely satisfied with the system of cavalry tactics which they had adopted, and looked with a certain air of superiority on the infantry tactics of their Roman predecessors. Justinian’s army and its achievements were indeed worthy of all praise; its victories were its own, while its defeats were generally due to the wretched policy of the emperor, who persisted in dividing up the command among many hands,--a system which secured military obedience at the expense of military efficiency. Justinian might, however, plead in his defence that the organization of the army had become such that it constituted a standing menace to the central power. The system of the Teutonic ‘comitatus,’ of the ‘war-band’ surrounding a leader to whom the soldiers are bound by a personal tie, had become deeply ingrained in the imperial forces. Always predominant among the Foederati, it had spread from them to the native corps. In the sixth century the monarch had always to dread that the loyalty of the troops towards their immediate commanders might prevail over their higher duties. Belisarius, and even Narses, were surrounded by large bodyguards of chosen men, bound to them by oath. That, of the former general at the time of his Gothic triumph amounted to 7000 veteran horsemen. The existence of such corps rendered every successful commander a possible Wallenstein, to use a name of more modern importance. Thus the emperor, in his desire to avert the predominance of any single officer, would join several men of discordant views in the command of an army, and usually ensure the most disastrous consequences. This organization of the imperial force in ‘banda,’[15] bodies attached by personal ties to their leaders, is the characteristic military form of the sixth century. Its normal prevalence is shown by the contemporary custom of speaking of each corps by the name of its commanding officer, and not by any official title. Nothing could be more opposed than this usage to old Roman
