The History of the Decline and Fall of the Roman Empire. Эдвард Гиббон
to offer an injury. The military strength, which it had been sufficient for Hadrian and the elder Antoninus to display, was exerted against the Parthians and the Germans by the emperor Marcus. The hostilities of the barbarians provoked the resentment of that philosophic monarch, and, in the prosecution of a just defence, Marcus and his generals obtained many signal victories, both on the Euphrates and on the Danube.Ref. 071 The military establishment of the Roman empire, which thus assured either its tranquillity or success, will now become the proper and important object of our attention.
In the purer ages of the commonwealth, the use of arms was reserved for those ranks of citizens who had a country to love, a property to defend, and some share in enacting those laws which it was their interest, as well as duty, to maintain. But in proportion as the public freedom was lost in extent of conquest, war was gradually improved into an art, and degraded into a trade.Ref. 072 The legions themselves, even at the time when they were recruited in the most distant provinces, were supposed to consist of Roman citizens. That distinction was generally considered either as a legal qualification or as a proper recompense for the soldier; but a more serious regard was paid to the essential merit of age, strength, and military stature.Ref. 073 In all levies, a just preference was given to the climates of the north over those of the south; the race of men born to the exercise of arms was sought for in the country rather than in cities, and it was very reasonably presumed that the hardy occupations of smiths, carpenters, and huntsmen would supply more vigour and resolution than the sedentary trades which are employed in the service of luxury.Ref. 074 After every qualification of property had been laid aside, the armies of the Roman emperors were still commanded, for the most part, by officers of a liberal birth and education; but the common soldiers, like the mercenary troops of modern Europe, were drawn from the meanest, and very frequently from the most profligate, of mankind.
That public virtue, which among the ancients was denominated patriotism, is derived from a strong sense of our own interest in the preservation and prosperity of the free government of which we are members. Such a sentiment, which had rendered the legions of the republic almost invincible, could make but a very feeble impression on the mercenary servants of a despotic prince; and it became necessary to supply that defect by other motives, of a different, but not less forcible nature, — honour and religion. The peasant, or mechanic, imbibed the useful prejudice that he was advanced to the more dignified profession of arms, in which his rank and reputation would depend on his own valour; and that, although the prowess of a private soldier must often escape the notice of fame, his own behaviour might sometimes confer glory or disgrace on the company, the legion, or even the army, to whose honours he was associated. On his first entrance into the service, an oath was administered to him with every circumstance of solemnity. He promised never to desert his standard, to submit his own will to the commands of his leaders, and to sacrifice his life for the safety of the emperor and the empire.Ref. 075 The attachment of the Roman troops to their standards was inspired by the united influence of religion and of honour. The golden eagle, which glittered in the front of the legion, was the object of their fondest devotion; nor was it esteemed less impious than it was ignominious, to abandon that sacred ensign in the hour of danger.Ref. 076 These motives, which derived their strength from the imagination, were enforced by fears and hopes of a more substantial kind. Regular pay, occasional donatives, and a stated recompense, after the appointed term of service, alleviated the hardships of the military life,Ref. 077 whilst, on the other hand, it was impossible for cowardice or disobedience to escape the severest punishment. The centurions were authorised to chastise with blows, the generals had a right to punish with death; and it was an inflexible maxim of Roman discipline, that a good soldier should dread his officers far more than the enemy. From such laudable arts did the valour of the Imperial troops receive a degree of firmness and docility, unattainable by the impetuous and irregular passions of barbarians.
And yet so sensible were the Romans of the imperfection of valour without skill and practice, that, in their language, the name of an army was borrowed from the word which signified exercise.Ref. 078 Military exercises were the important and unremitted object of their discipline. The recruits and young soldiers were constantly trained, both in the morning and in the evening, nor was age or knowledge allowed to excuse the veterans from the daily repetition of what they had completely learnt. Large sheds were erected in the winter-quarters of the troops, that their useful labours might not receive any interruption from the most tempestuous weather; and it was carefully observed, that the arms destined to this imitation of war should be of double the weight which was required in real action.Ref. 079 It is not the purpose of this work to enter into any minute description of the Roman exercises. We shall only remark that they comprehended whatever could add strength to the body, activity to the limbs, or grace to the motions. The soldiers were diligently instructed to march, to run, to leap, to swim, to carry heavy burdens, to handle every species of arms that was used either for offence or for defence, either in distant engagement or in a closer onset; to form a variety of evolutions; and to move to the sound of flutes in the Pyrrhic or martial dance.Ref. 080 In the midst of peace, the Roman troops familiarised themselves with the practice of war; and it is prettily remarked by an ancient historian who had fought against them, that the effusion of blood was the only circumstance which distinguished a field of battle from a field of exercise.Ref. 081 It was the policy of the ablest generals, and even of the emperors themselves, to encourage these military studies by their presence and example; and we are informed that Hadrian, as well as Trajan, frequently condescended to instruct the inexperienced soldiers, to reward the diligent, and sometimes to dispute with them the prize of superior strength or dexterity.Ref. 082 Under the reigns of those princes, the science of tactics was cultivated with success; and as long as the empire retained any vigour, their military instructions were respected as the most perfect model of Roman discipline.
Nine centuries of war had gradually introduced into the service many alterations and improvements. The legions, as they are described by Polybius,Ref. 083 in the time of the Punic wars, differed very materially from those which achieved the victories of Cæsar, or defended the monarchy of Hadrian and the Antonines. The constitution of the Imperial legion may be described in a few words.Ref. 084 The heavy-armed infantry, which composed its principal strength,Ref. 085 was divided into ten cohorts, and fifty-five companies, under the orders of a correspondent number of tribunes and centurions. The first cohort, which always claimed the post of honour and the custody of the eagle, was formed of eleven hundred and five soldiers, the most approved for valour and fidelity. The remaining nine cohorts consisted each of five hundred and fifty-five; and the whole body of legionary infantry amounted to six thousand one hundred men. Their arms were uniform, and admirably adapted to the nature of their service: an open helmet, with a lofty crest; a breast-plate, or coat of mail; greaves on their legs, and an ample buckler on their left arm. The buckler was of an oblong and concave figure, four feet in length, and two and a half in breadth, framed of a light wood, covered with a bull’s hide, and strongly guarded with plates of brass. Besides a lighter spear, the legionary soldier grasped in his right hand the formidable pilum, a ponderous javelin, whose utmost length was about six feet, and which was terminated by a massy triangular point of steel of eighteen inches.Ref. 086 This instrument was indeed much inferior to our modern fire-arms; since it was exhausted by a single discharge, at the distance of only ten or twelve paces. Yet, when it was launched by a firm and skilful hand, there was not any cavalry that durst venture within its reach, nor any shield or corslet that could sustain the impetuosity of its weight. As soon as the Roman had darted his pilum, he drew his sword, and rushed forwards to close with the enemy. It was a short well-tempered Spanish blade, that carried a double edge, and was alike suited to the purpose of striking or of pushing; but the soldier was always instructed to prefer the latter use of his weapon, as his own body remained less exposed, whilst he inflicted a more dangerous wound on his adversary.Ref. 087 The legion was usually drawn up eight deep; and the regular distance of three feet was left between the files as well as ranks.Ref. 088 A body of troops, habituated to preserve this open order, in a long front and a rapid charge, found themselves prepared to execute every disposition which the circumstances of war, or the skill of their leader, might suggest. The soldier possessed a free space for his arms and motions, and sufficient intervals were allowed, through which seasonable reinforcements might
