To secure the frontiers, Justinian adopted a plan of constructing extensive lines supported by innumerable forts and castles, in which he placed garrisons, in order that they might be ready to sally out on the invading bands. These lines extended from the Adriatic to the Black Sea, and were further strengthened by the long wall of Anastasius, which covered Constantinople by walls protecting the Thracian Chersonesus and the peninsula of Pallene, and by fortifications at Thermopylæ, and at the Isthmus of Corinth, which were all carefully repaired. At all these posts permanent garrisons were maintained. The eulogy of Procopius on the public edifices of Justinian seems almost irreconcilable with the events of the latter years of his reign; for Zabergan, king of the Huns, penetrated through breaches he found unrepaired in the long wall, and advanced almost to the very suburbs of Constantinople.
Another instance of the declining state of military tactics may be mentioned, as it must have originated in the army itself, and not in consequence of any arrangements of the government. The combined manœuvres of the divisions of the regiments had been so neglected that the bugle-calls once used had fallen into desuetude, and were unknown to the soldiers. The motley recruits, of dissimilar habits, could not acquire with the requisite rapidity a perception of the delicacy of the ancient music, and the Roman infantry no longer moved
“In perfect phalanx, to the Dorian mood,
Of flutes and soft recorders.”
It happened, during the siege of Auximum in Italy, that Belisarius was placed in difficulty from the want of an instantaneous means of communicating orders to the troops engaged in skirmishing with the Goths. On this occasion it was suggested to him by Procopius, his secretary and the historian of his wars, to replace the forgotten bugle-calls by making use of the brazen trumpet of the cavalry to sound a charge, and of the infantry bugle to summon a retreat.
Foreigners were preferred by the emperors as the occupants of the highest military commands; and the confidence with which the barbarian chiefs were honoured by the court enabled many to reach the highest rank in the army. Narses, the most distinguished military leader after Belisarius, was a Pers-Armenian captive. Peter, who commanded against the Persians in the campaign of 528, was also a Pers-Armenian. Pharas, who besieged Gelimer in Mount Pappua, was a Herulian. Mundus, who commanded in Illyria and Dalmatia, was a Gepid prince. Chilbud, who, after several victories, perished with his army in defending the frontiers against the Slavonians, was of northern descent, as may be inferred from his name. Solomon, who governed Africa with great courage and ability, was a eunuch from Dara. Artaban was an Armenian prince. Johannes Troglita the patrician, the hero of the poem of Corippus called the
It became the fashion in the army to imitate the manners and habits of the barbarians; their headlong personal courage became the most admired quality, even in the highest rank; and nothing tended more to hasten the decay of the military art. The officers in the Roman armies became more intent on distinguishing themselves for personal exploits than for exact order and strict discipline in their corps. Even Belisarius himself appears at times to have forgotten the duties of a general in his eagerness to exhibit his personal valour on his bay charger; though he may, on such occasions, have considered that the necessity of keeping up the spirits of his army was a sufficient apology for his rashness. Unquestionably the army, as a military establishment, had declined in excellence ere Justinian ascended the throne, and his reign tended to sink it much lower; yet it is probable that it was never more remarkable for the enterprising valour of its officers or for their personal skill in the use of their weapons. The death of numbers of the highest rank, in battles and skirmishes in which they rashly engaged, proves this fact. There was, however, one important feature of ancient tactics still preserved in the Roman armies, which gave them a decided superiority over their enemies. They had still the confidence in their discipline and skill to form their ranks, and encounter their opponents in line; the bravest of their enemies, whether on the banks of the Danube or the Tigris, only ventured to charge them, or receive their attack, in close masses.
