Military Institutions of the Romans – Vegetius

U

Synopsis:

Late antiquity engendered consequential institutional adjustments for Roman arms. The wealth of the state meant that Rome would always attract the best recruits to its standard, but commonly these recruits were foreign mercenaries. Although still effective the army over time became more and more challenging to control because of foreign preeminence.

The Western Roman Empire never solved the problem of the barbarianization of its army, but rather was taken over by it, and collapsed as a state in 476. On the other hand, the Eastern Roman Empire answered the institutional dilemma of barbarianization first by elevating the hard-bitten Isaurian Romans of Anatolia to supremacy over the formerly favored barbarian mercenaries, and later by establishing the militia thémata system.

The late Roman writer Vegetius sought to unravel the institutional riddle of the late Roman army by advancing the thesis of how the ideal Roman army ought to be organized. His work never reflected the reality of late antiquity, but would become influential in the medieval West.

Excerpts:

“Victory in war does not depend entirely upon numbers or mere courage; only skill and discipline will insure it.

“Recruits in particular should be obliged frequently to carry a weight of not less than sixty pounds (exclusive of their arms), and to march with it in the ranks. This is because on difficult expeditions they often find themselves under the necessity of carrying their provisions as well as their arms.

“The courage of a soldier is heightened by his knowledge of his profession, and he only wants an opportunity to execute what he is convinced he has been perfectly taught. A handful of men, inured to war, proceed to certain victory, while on the contrary numerous armies of raw and undisciplined troops are but multitudes of men dragged to slaughter.

“Troops, defenseless and exposed to all the weapons of the enemy, are more disposed to fly than fight.

“To pretend to enumerate the different nations so formidable of old, all which now are subject to the Romans, would be tedious. But the security established by long peace has altered their dispositions, drawn them off from military to civil pursuits and infused into them a love of idleness and ease. Hence a relaxation of military discipline insensibly ensued, then a neglect of it, and it sunk at last into entire oblivion.

The Decline of Roman Power in the West – J.B. Bury

M

Synopsis:

In The Invasion of Europe by the Barbarians, distinguished historian J.B. Bury offers a narrative account of the deluge of barbarian invasions, and mass migrations which afflicted the Roman Empire in the fifth century AD. He also chronicles the early evolution of the barbarian kingdoms in Western Europe throughout late antiquity.

The chapter Bury dedicates to the decline of Roman power in the western half of the empire centers on the institutional collapse of the state, and the ensuing snowball of barbarianization within the army. The barbarianization of the army thus allowed for the eventual consummation of an Italian kingdom under the rule of the barbarian warlord Odovacar.

Excerpts:

“The contribution which the Vandals made to the shaping of Europe was this: the very existence of their kingdom in Africa, and of their naval power in the Mediterranean, acted as a powerful protection for the growth of the new German kingdoms in Gaul and Spain, and ultimately helped the founding of a German kingdom in Italy, by dividing, diverting, and weakening the forces of the Empire. The Vandals had got round, as it were, to the rear of the Empire; and the effect of their powerful presence there was enhanced by the hostile and aggressive attitude which they continuously adopted.

“He (Ricimer) became through circumstances an emperor-maker; and his difficulty was this. If he set up too strong a man, his own power would have probably been overridden; his own fall would have been the consequence; while on the other hand weak upstarts were unable to maintain their position for any length of time, since public opinion did not respect them.

“It is also to be noted that in the intervals between the reigns of the emperors whom Ricimer set up and pulled down, when there was no emperor regnant in Italy, it did not mean that there was no emperor at all. At such times the imperial authority was entirely invested in the eastern emperor who reigned at Constantinople, the Emperor Leo; and this, too, was fully acknowledged by Ricimer, who indeed selected two of his emperors by arrangement with Leo.

“Odovacar had statesmanlike qualities, and he decided against the system of Ricimer, which had proved thoroughly unsatisfactory and unstable. His idea was to rule Italy under the imperial authority of Constantinople, unhampered by a second emperor in Italy, whom recent experiences had show to be worse than useless. There would have been no difficulty for Odovacar in adopting this policy, if there had existed no second emperor at the time; but Julius Nepos was still alive, and, what was most important, he had been recognized at Constantinople.

“Odovacar was not hampered, as Ricimer had been, by the nominal authority of a resident emperor; he was able to pursue his own policy without any embarrassment, and to act as an independent ruler. His policy was one of peace; he was entirely averse from aggression. It must be noted, too, that his position was much easier than that of Ricimer, because the Vandal hostilities had ceased. Gaiseric had died in 477; and two years before his death he had made peace with Rome, and Odovacar had induced him to restore Sicily in return for a yearly payment.

The Byzantine Art of War: Strategy and Tactics – Michael J. Decker

33

Synopsis:

Chapter 5 of Michael J. Decker’s book on the Byzantine art-of-war recounts the strategy and tactics used by the Byzantine Empire throughout its long history. Decker discusses the stratagems, imperial ideology, and organization of the Byzantine state apparatus centered in its capital city of Constantinople. Following the conquest of Constantinople by the Fourth Crusade in 1204 this apparatus was irrevocably destroyed by the Latin West, and even after the reconquest of the city by the Greeks it was never again on the same order of magnitude or effectiveness as before.

Excerpts:

“…All wars were defensive. Even offensive campaigns were considered defensive, in that they aimed to recover land that had been seized from the empire and rightfully belonged to it, and this notion of the ‘forward defense’ or ‘active defense’ was something that the Romans probably imparted to Muslim jihad theorists.

“Experience taught the emperors that any period of peace was fleeting; never did this come into such sharp clarity more than in the events of the late 620s and 630s, when Heraclius found himself at the top of the wheel of fortune with his victories over the Persians, symbolized by his triumphant entry into Jerusalem in a spirit of millennial jubilation. The wheel turned, however, and within a decade Arab forces seized the whole of the Levant.

“Since the reign of Constantine I, the Romans had understood that the universe was ordered according to the principles of Christianity and the world was a reflection of the unseen cosmos:one God, one faith, one emperor, one empire.

“Subterfuge, bribery, and disinformation were prized bloodless means to undermine or dissolve enemies and were always preferred to open battle. The military manuals instruct, whenever possible, to bribe enemy commanders. Before campaigns on the frontiers, the general Nikephoros Ouranos (ca. 950-1011) ordered that gifts be sent to the emirs along the border in order for the bearers to collect intelligence and possibly induce the enemy to the Byzantine side or at least inaction in the coming conflict.

“The handbooks stress the need to surprise the enemy. Strategic surprise could be achieved by avoiding enemy agents, by disinformation, and by unexpected marches. The Strategikon warns that to avoid enemy spies armies should take little-used routes and march through uninhabited areas that were less likely to be under surveillance.

Justinian’s Military Organization – Hans Delbrück

Synopsis:

In the second volume of his History of the Art of War, Hans Delbrück devotes a chapter in book three to the military organization of the early Byzantine/late Roman Empire under the emperor Justinian. He examines the dissolution of discipline within the ranks, as well as the transition to a generally cavalry centered army. This more mobile force than the famous legions of previous epochs – particularly the republican one – was the culmination of centuries of evolution within the Roman army that had commenced under the emperor Gallienus. The resultant innovations from this transformation would give Justinian the edge in escalation dominance over the barbarian kingdoms in the West, and would open-the-door to a Roman re-conquest of North Africa, Sicily, and the Italian peninsula – all within the span of forty years.

Excerpts:

“The active armies were quite small. Belisarius had 25,000 men when he won his victory over the Persians at Daras in 530. He landed in Africa with no more than 15,000 men, and of these 15,000, the 5,000 cavalry included in that total were sufficient to defeat the Vandals in the open field. Even smaller was the army with which Belisarius moved to Italy in order to destroy the East Gothic Kingdom eleven years after Theodoric’s death: there were no more than 10,000 to 11,000 men.

“A contemporary author, Agathias (5. 13), estimated that the total Roman army must have been 645,000 men strong but that only 150,000 men were actually available under Justinian.

“A very large number of the soldiers with whom Belisarius had conquered Italy deserted to the Goths when, after he was relieved, the Roman domination again collapsed and Totila established the Gothic kingdom.

“After the fourth century A.D., and after the disappearance of the legions, everything changed. The barbarian mercenaries now felt that they were the masters. Woe to the prince or the general who might have dared to incur their displeasure by his strictness!

“Procopius considers it a half-miracle and an extraordinary accomplishment of Belisarius that the Romans marched into Carthage in good order, ‘whereas otherwise the Roman troops never march into their own cities without disorder, even if there are only 500 of them.
