Chapter I: The Conquests of the Romans (2)

Still, Mithridates was not subdued, and Pompey, who had annihilated the Mediterranean pirates, was the only person fit to finish the Mithridatic war. His successes had been more brilliant than even those of Sulla, or Lucullus, or Metellus. He was made Dictator of the East, with greater powers than had ever before been intrusted to a Roman general. He had success equal to his fame; drove Mithridates across the Caucasus; reduced Pontus, and took possession of Syria, which had been subject to Tigranes. The defeated King of Pontus, who had sought to unite all the barbarous tribes of Eastern Europe against Rome, destroyed himself. Pompey, after seven years' continued successes, returned to Italy to claim his triumph, having subdued the East, and added the old monarchy of the Seleucidae to the dominion of Rome, B.C. 61.

[Sidenote: His victories in Spain.]

[Sidenote: Caesar sent into Gaul.]

But while Pompey was pursuing his victories over the effeminate people of Asia, a still more brilliant career in the West marked the rising fortunes of Julius Caesar. I need not dwell on the steps by which he arose to become the formidable rival of the conqueror of the East. He bears the most august name of antiquity. A patrician by birth, a demagogue in his principles, popular in his manners, unscrupulous in his means, he successively passed through the various great offices of state, which he discharged with prodigious talent. As leader of the old popular party of Marius, he sought the humiliation of the Senate, while his ambition led him to favor every enterprise which promised to advance his own interests. Leaving the province of Spain, after his praetorship, before Pompey's return to Italy, his great career of conquest commenced. He first availed himself of some disturbances in Lusitania to declare war against its gallant people, overran their country, and then turned his arms against the Gallicians. In two years he had obtained spoils more than sufficient to pay his enormous debts, the result of his prodigality, by which, however, he won the hearts of the thoughtless citizens, and paved the way for honor. Conqueror of Spain, and idol of the people, he returned to Rome, B.C. 60, when Pompey was quarreling with the Senate, formed an alliance with him and Crassus, and by their aid was elected consul. His measures in that high office all tended to secure his popularity with the people, and supported by Pompey and Crassus, he triumphed over the Senate. He then secured the government of Cisalpine Gaul and Illyricum, with two legions, for the extraordinary term of five years. The Senate added the province of Transalpine Gaul, then threatened by the Allobrogians, Suevi, Helvetians, and other barbaric tribes, with the intention of confining him to a dangerous and uncertain field of warfare.

[Sidenote: His great military genius.]

[Sidenote: His difficulties in the conquest of Gaul.]

[Sidenote: Results of the Gaulish wars.]

[Sidenote: Gaul becomes Latinized.]

That field, however, established his military fame, and paved the way for his subsequent usurpations. The conquests of Caesar in Western Europe are unique in the history of war, and furnish no parallel. Other conquests may have been equally brilliant and more imposing, but none were ever more difficult and arduous, requiring greater perseverance, energy, promptness, and fertility of resources. The splendid successes of Lucullus and Pompey in Asia resembled those of Alexander. We see military discipline and bravery triumphing over the force of multitudes, and a few thousand men routing vast armies of enervated or undisciplined mercenaries. Such were the conquests of the English in India. They make a great impression, but the fortunes of an empire are decided by a single battle. It was not so with the conflicts of Caesar in Gaul. He had to fight with successive waves of barbarians, inured to danger, adventurous and hardy, holding life in little estimation, willing to die in battle, intrepid in soul, and bent on ultimate victory. He had to fight in hostile territories, unacquainted with the face of the country, at a great distance from the base of his supplies, exposed to perpetual perils, and surrounded with unknown difficulties. And these were appreciated by his warlike countrymen, who gave him the credit he deserved. The ten years he spent in Gaul were the years of his truest glory, and the most momentous in their consequences on the future civilization of the world, since it was not worn-out monarchies he added to the empire, but a new territory, inhabited by brave and simple races, who were to learn the arts and laws and literature of Rome, and supply the government with powerful aid in the decline of its strength. It was the conquered barbarians who, henceforth, were to furnish Rome with soldiers, and even scholars and statesmen and generals. Among them the old civilization was to take root, among them new states were to arise on which the Romans could impress their own remarkable characteristics. It was the western provinces of the empire that alone were vital with energy and strength, and which were destined to perpetuate the spirit of Roman institutions. The eastern provinces never lost the impress of the Greek mind and manners. They remained Greek even when subdued by the imperial legions. Syria, Asia Minor, Egypt, were filled with Grecian cities, and Asiatic customs were modified by Grecian civilization. The West was purely Roman, and the Latin language, laws, and arts were continued, in a modified form, through the whole period of the Middle Ages. Even Christianity had a different influence in the West from what it had in the East. In other words, the West was completely Latinized, while the East remained Grecian. Though the East was governed by Roman proconsuls, they could not change the Graeco-Asiatic character of its institutions and manners; but the barbarians were willing to learn new lessons from their Roman masters.

[Sidenote: Greatness of Caesar.]

It would require a volume to describe the various campaigns of Caesar in Gaul, in which a million of people were destroyed. But I only aim to show results. Most people are familiar with the marvelous generalship and enterprises of the Roman conqueror--the conquest and reconquest of the brave barbarians, most of whom were Celts; the uprising of Germanic tribes as well, and their fearful slaughter near Coblentz; the bloody battles, the fearful massacres, the unscrupulous cruelties which he directed; the formidable insurrection organized by Vercingetorix; the spirit he infused into his army; the incessant hardships of the soldiers, crossing rivers, mountains, and valleys, marching with their heavy burdens--fighting amid every disadvantage, until all the countries north of the Alps and west of the Rhine acknowledged his sway-- all these things are narrated by Caesar himself with matchless force and simplicity of language.

[Sidenote: Rivalry between Caesar and Pompey.]

Caesar now probably aspired to the sovereignty of the empire, as Napoleon did after the conquest of Italy. But he had a great rival in Pompey, who had remained chiefly at Rome, during his Gaulish campaigns, virtually dictator, certainly the strongest citizen. And Pompey had also his ambitious schemes. One was the conqueror of the East; the other of the West. One leaned to the aristocratic party, the other to the popular. Pompey was proud, pompous, and self-sufficient. Caesar was politic, patient, and intriguing. Both had an inordinate ambition, and both were unscrupulous. Pompey had more prestige, Caesar more genius. Pompey was a greater tactician, Caesar a greater strategist. The Senate rallied around the former, the people around the latter. Cicero distrusted both, and flattered each by turns, but inclined to the side of Pompey, as belonging to the aristocratic party.

[Sidenote: Battle of Pharsalia.]

[Sidenote: Death of Pompey.]

Between such ambitious rivals coalition for any length of time could not continue. Dissensions arose between them, and then war. The contest was decided at Pharsalia. On the 6th of June, B.C. 48, "Greek met Greek," yet with forces by no means great on either side. Pompey had only forty thousand, and Caesar less, but they were veterans, and the victory was complete. Pompey fled to Egypt, without evincing his former greatness, paralyzed, broken, and without hope. There he miserably died, by the assassin's dagger, at the age of sixty, and the way was now prepared for the absolute rule of Caesar.

[Sidenote: Dictatorship of Caesar.]

But the party of Pompey rallied, connected with which were some of the noblest names of Rome. The battle of Thapsus proved as disastrous to Cato as Pharsalia did to Pompey. Caesar was uniformly victorious, not merely over the party which had sustained Pompey, but in Asia, Africa, and Spain, which were in revolt. His presence was everywhere required, and wherever he appeared his presence was enough. He was now dictator for ten years. He had overturned the constitution of his country. He was virtually the supreme ruler of the world. In the brief period which passed from his last triumphs to his death, he was occupied in legislative labors, in settling military colonies, in restoring the wasted population of Italy, in improving the city, in reforming the calendar, and other internal improvements, evincing an enlarged and liberal mind.

[Sidenote: Death of Caesar. His character.]

But the nobles hated him, and had cause, in spite of his abilities, his affability, magnanimity, and forbearance. He had usurped unlimited authority, and was too strong to be removed except by assassination. I need not dwell on the conspiracy under the leadership of Brutus, and his tragic end in the senate-house, where he fell, pierced by twenty-two wounds, at the base of Pompey's statue, the greatest man in Roman history--great as an orator, a writer, a general, and a statesman; a man without vanity, devoted to business, unseduced by pleasure, unscrupulous of means to effect an end; profligate, but not more so than his times; ambitious of power, but to rule, when power was once secured, for the benefit of his country, like many other despots immortal on a bloody catalogue. After his passage of the Rubicon his career can only be compared with that of Napoleon.

[Sidenote: Character of his later wars.]

But Roman territories were not much enlarged by Caesar after the conquest of Celtic Europe. His later wars were either against rivals or to settle distracted provinces. Nor were they increased in the civil wars which succeeded his death, between the various aspirants for the imperial power and those who made one more stand for the old constitution. At the fatal battle of Philippi, when the hopes of Roman patriots vanished forever, double the number of soldiers were engaged on both sides than at Pharsalia, but fortune had left the senatorial party, of which Brutus was the avenger and the victim.

[Sidenote: Civil wars after the death of Caesar.]

[Sidenote: Ascendency of Octavian.]

Civil war was carried on most vigorously after the death of Julius. But it was now plainly a matter between rival generals and statesmen for supreme command. The chief contest was between Octavian and Antony, the former young, artful, self-controlled, and with transcendent abilities as a statesman; the latter bold, impetuous, luxurious, and the ablest of all Caesar's lieutenants as a general. Had he not yielded to the fascinations of Cleopatra, he would probably have been the master of the world. But the sea-fight of Actium, one of the great decisive battles of history, gave the empire of the world to Octavian B.C. 31, and two years after the victor celebrated three magnificent triumphs, after the example of his uncle, for Dalmatia, Actium, and Egypt. The kingdom of the Ptolemies passed under the rule of Caesar. The Temple of Janus was shut, for the first time for more than two hundred years; and the imperial power was peaceably established over the civilized world.

[Sidenote: Necessity for the empire.]

The friends of liberty may justly mourn over the fall of republican Rome, and the centralization of all power in the hands of Augustus. But it was a calamity which could not be averted, and was a revolution which was in accordance with the necessities of the times. Fifty years' civil war taught the Romans the hopelessness of the struggle to maintain their old institutions so long as the people were corrupt, and fortunate generals would sacrifice the public welfare to their ambition. Order was better than anarchy, even though a despot reigned supreme. When men are worse than governments, they must submit to the despotism of tyrants. It is idle to dream of liberty with a substratum of folly and vice. The strongest man will rule, but whether he rule wisely or unwisely, there is no remedy. Providence gave the world to the Romans, after continual and protracted wars for seven hundred years; and when the people who had conquered the world by their energy, prudence, and perseverance, were no longer capable of governing themselves, then the state fell into the possession of a single man.

[Sidenote: Change in the imperial policy.]

Under the emperors, the whole policy of the government was changed. They no longer thought of further aggrandizement, but of retaining the conquests which were already made. And if they occasionally embarked in new wars, those wars were of necessity rather than of ambition, were defensive rather than aggressive. New provinces were from time to time added, but in consequence of wars which were waged in defense of the empire. The conquest of Britain and Judea was completed, and various conflicts took place with the Germanic nations, who, in the reign of Antoninus, formed a general union for the invasion of the Roman world. These barbarians were the future aggressors on the peace of the empire, until it fell into their hands. The empire of Augustus may be said to have reached the utmost limits it ever permanently retained, extending from the Rhine and the Danube to the Euphrates and Mount Atlas, embracing a population variously estimated from one hundred to one hundred and thirty millions.

[Sidenote: Perfection of military art.]

When Augustus became the sovereign ruler of this vast empire, military art had reached the highest perfection it ever attained among any of the nations of antiquity. It required centuries to perfect this science, if science it may be called, and the Romans doubtless borrowed from the people whom they subdued. They learned to resist the impetuous assaults of semi-barbarous warriors, the elephants of the East, and the phalanx of the Greeks. Military discipline was carried to the severest extent by Marius, Pompey, and Caesar.

[Sidenote: The spirit of the Roman soldier.]

The Roman soldier was trained to march twenty miles a day, under a burden of eighty pounds; yea, to swim rivers, to climb mountains, to penetrate forests, and to encounter every kind of danger. He was taught that his destiny was to die in battle. He expected death. He was ready to die. Death was his duty, and his glory. He enlisted in the armies with little hope of revisiting his home. He crossed seas and deserts and forests with the idea of spending his life in the service of his country. His pay was only a denarius daily, equal to about sixteen cents of our money. Marriage was discouraged or forbidden. He belonged to the state, and the state was exacting and hard. He was reduced to abject obedience, yet he held in his hand the destinies of the empire. And however insignificant was the legionary as a man, he gained importance from the great body with which he was identified. He was the servant and the master of the state. He had an intense _esprit de corps_. He was bound up in the glory of his legion. Both religion and honor bound him to his standards. The golden eagle which glittered in his front was the object of his fondest devotion. Nor was it possible to escape the penalty of cowardice or treachery, or disobedience. He could be chastised with blows by his centurion; his general could doom him to death. Never was the severity of military discipline relaxed. Military exercises were incessant, in winter as in summer. In the midst of peace the Roman troops were familiarized with the practice of war.

[Sidenote: Military genius of the Romans.]

[Sidenote: The perfection of military art.]

It was the spirit which animated the Roman legions, and the discipline to which they were inured, which gave them their irresistible strength. When we remember that they had not our fire-arms, we are surprised at their efficiency, especially in taking strongly fortified cities. Jerusalem was defended by a triple wall, and the most elaborate fortifications, and twenty-four thousand soldiers, beside the aid received from the citizens; and yet it fell in little more than four months before an army of eighty thousand under Titus. How great the science to reduce a place of such strength, in so short a time, without the aid of other artillery than the ancient catapult and battering-ram! Whether the military science of the Romans was superior or inferior to our own, no one can question that it was carried to utmost perfection before the invention of gunpowder. We are only superior in the application of this great invention, especially in artillery. There can be no doubt that a Roman army was superior to a feudal army in the brightest days of chivalry. The world has produced no generals superior to Caesar, Pompey, Sulla, and Marius. No armies ever won greater victories over superior numbers than the Roman, and no armies of their size, ever retained in submission so great an empire, and for so long a time. At no period in the history of the empire were the armies so large as those sustained by France in time of peace. Two hundred thousand legionaries, and as many more auxiliaries, controlled diverse nations and powerful monarchies. The single province of Syria once boasted of a military force equal in the number of soldiers to that wielded by Tiberius. Twenty-five legions made the conquest of the world, and retained that conquest for five hundred years. The self-sustained energy of Caesar in Gaul puts to the blush the efforts of all modern generals, except Frederic II., Marlborough, Napoleon, Wellington, Grant, Sherman, and a few other great geniuses which a warlike age developed; nor is there a better text-book on the art of war than that furnished by Caesar himself in his Commentaries. And the great victories of the Romans over barbarians, over Gauls, over Carthaginians, over Greeks, over Syrians, over Persians, were not the result of a short-lived enthusiasm, like those of Attila and Tamerlane, but extended over a thousand years. The Romans were essentially military in all their tastes and habits. Luxurious senators and nobles showed the greatest courage and skill in the most difficult campaigns. Antony, Caesar, Pompey, and Lucullus were, at home, enervated and luxurious, but, at the head of the legions, were capable of any privation and fatigue. The Roman legion was a most perfect organization, a great mechanical force, and could sustain furious attacks after vigor, patriotism, and public spirit had fled. For three hundred years a vast empire was sustained by mechanism alone.

[Sidenote: The cavalry.]

[Sidenote: Term of military service.]

The legion is coeval with the foundation of Rome, but the number of the troops of which it was composed varied at different periods. It rarely exceeded six thousand men. Gibbon estimates the number at six thousand eight hundred and twenty-six men. For many centuries it was composed exclusively of Roman citizens. Up to the year B.C. 107, no one was permitted to serve among the regular troops except those who were regarded as possessing a strong personal interest in the stability of the republic. Marius admitted all orders of citizens; and after the close of the Social War, B.C. 87, the whole free population of Italy was allowed to serve in the regular army. Claudius incorporated with the legion the vanquished Goths, and after him the barbarians filled up the ranks, on account of the degeneracy of the times. But during the period when the Romans were conquering the world every citizen was trained to arms, and was liable to be called upon to serve in the armies. In the early age of the republic, the legion was disbanded as soon as the special service was performed, and was in all essential respects a militia. For three centuries, we have no record of a Roman army wintering in the field; but when Southern Italy became the seat of war, and especially when Rome was menaced by foreign enemies, and still more when a protracted foreign service became inevitable, the same soldiers remained in activity for several years. Gradually the distinction between the soldier and the civilian was entirely obliterated. The distant wars of the republic, like the prolonged operations of Caesar in Gaul, and the civil contests, made a standing army a necessity. During the civil wars between Caesar and Pompey, the legions were forty in number; under Augustus but twenty-five. Alexander Severus increased them to thirty-two. This was the standing force of the empire, from one hundred and fifty to two hundred and forty thousand men, and this was stationed in the various provinces. The main dependence of the legion was on the infantry, which wore heavy armor consisting of helmet, breastplate, greaves on the legs, and buckler on the left arm four feet in length and two and a half in width. The helmet was originally made of leather or skin, strengthened and adorned by bronze or gold, and surmounted by a crest which was often of horse-hair, and so made as to give an imposing look The crest not only served for ornament but to distinguish the different centurions. The breastplate or cuirass was generally made of metal, and sometimes was highly ornamented. Chain-mail was also used. The greaves were of bronze or brass, with a lining of leather or felt, and reached above the knees. The shield, worn by the heavy-armed infantry, was not round, like that of the Greeks, but oval or oblong, adapted to the shape of the body, and was made of wood or wicker-work. The weapons were a light spear, a pilum or javelin six feet long, terminated by a steel point, and a sword with a double edge, adapted to striking or pushing. The legion was drawn up eight deep, and three feet intervened between rank and file, which disposition gave great activity, and made it superior to the Macedonian phalanx, the strength of which depended on sixteen ranks of long pikes wedged together. The cavalry attached to each legion were three hundred men, and they originally were selected from the leading men in the state. They were mounted at the expense of the state, and formed a distinct order. The cavalry was divided into ten squadrons; and to each legion was attached a train of ten military engines of the largest size, and fifty-five of the smaller,--all of which discharged stones and darts with great effect. This train corresponded with our artillery. Besides the armor and weapons of the legionaries they usually carried on their marches provisions for two weeks, and three or four stakes used in forming the palisade of the camp, beside various tools,--altogether a burden of sixty or eighty pounds per man. The general period of service for the infantry was twenty years, after which the soldier received a discharge together with a bounty in money or land.

[Sidenote: The Hastati.]

[Sidenote: The Principes and Velites.]

[Sidenote: The Triarii.]

[Sidenote: The Pilarii.]

[Sidenote: The Equites.]

The Roman legion, whether it was composed of four thousand men, as in the early ages of the republic or six thousand, as in the time of Augustus, of was divided into ten cohorts, and each cohort was composed of Hastati, Principes, Triarii, and Velites. The soldiers of the first line, called Hastati, consisted of youths in the bloom of manhood, and were distributed into fifteen companies or maniples. Each company contained sixty privates, two centurions, and a standard-bearer. Two thirds were heavily armed, and bore the long shield, the remainder carried only a spear and light javelins. The second line, the Principes, was composed of men in the full vigor of life, divided also into fifteen companies, all heavily armed, and distinguished by the splendor of their equipments. The third body, the Triarii, was also composed of tried veterans, in fifteen companies, the least trustworthy of which were placed in the rear. These formed three lines. The Velites were light- armed troops, employed on outpost duty, and mingled with the horsemen. The Hastati were so called because they were armed with the hasta; the Principes, for being placed so near to the front; the Triarii, from having been arrayed behind the first two lines as a body of reserve, armed with the pilum, thicker and stronger than the Grecian lance,--four and a half feet long, of wood, with a barbed head of iron,--so that the whole length of the weapon was six feet nine inches. It was used either to throw or thrust with, and when it pierced the enemy's shield, [Footnote: Liv. viii. 8.] the iron head was bent, and the spear, owing to the twist in the iron, still held to the shield. [Footnote: Plut. Mar. 25.] Each soldier carried two of these weapons. [Footnote: Polyb. vi. 23.] The Principes were in the front ranks of the phalanx, clad in complete defensive armor,--men in the vigor of strength. The Pilarii were in the rear, who threw the heavy pilum over the heads of their comrades, in order to break the enemy's line. In the time of the empire, when the legion was modified, the infantry wore cuirasses and helmets, and two swords; namely, a long one and a dagger. The select infantry carried a long spear and a shield, the rest a pilum. Each man carried a saw, a basket, a mattock, a hatchet, a leather strap, a hook, a chain, and provisions for three days. The Equites wore helmets and cuirasses, like the infantry, with a broad sword at the right side, and in their hand a long pole. A buckler swung at the horse's flank. They were also furnished with a quiver containing three or four javelins.

[Sidenote: The artillery.]

[Sidenote: The Testudo.]

[Sidenote: The Helepolis.]

[Sidenote: The Turris.]

[Sidenote: Scailing-ladders.]

The artillery were used both for hurling missiles in battle, and for the attack of fortresses. The _tormentum_, which was an elastic instrument, discharged stones and darts, and was continued until the discovery of gunpowder. In besieging a city, the ram was employed for destroying the lower part of a wall, and the balista, which discharged stones, was used to overthrow the battlements. The balista would project a stone weighing from fifty to three hundred pounds. The _aries_, or battering-ram, consisted of a large beam made of the trunk of a tree, frequently one hundred feet in length, to one end of which was fastened a mace of iron or bronze, which resembled in form the head of a ram, and was often suspended by ropes from a beam fixed transversely over it, so that the soldiers were relieved from supporting its weight, and were able to give it a rapid and forcible motion backward and forward. And when this machine was further aided by placing a frame in which it was suspended upon wheels, and constructing over it a roof, so as to form a _testudo_, which protected the besieging party from the assaults of the besieged, there was no tower so strong, no wall so thick, as to resist a long-continued attack. Its great length enabled the soldiers to work across the ditch, and as many as one hundred men were often employed upon it. The Romans learned from the Greeks the art of building this formidable engine, which was used with great effect by Alexander, but with still greater by Vespasian in the siege of Jerusalem. It was first used by the Romans in the siege of Syracuse. The _vinea_ was a sort of roof under which the soldiers protected themselves when they undermined walls. The _helepolis_, also used in the attack of cities, was a square tower furnished with all the means of assault. This also was a Greek invention, and that used by Demetrius at the siege of Rhodes, B.C. 306, was one hundred and thirty-five feet high and sixty- eight wide, divided into nine stories. Towers of this description were used at the siege of Jerusalem, [Footnote: Josephus _B. J._, ii. 19.] and were manned by two hundred men employed upon the catapults and rams. The _turris_, a tower of the same class, was used both by Greeks and Romans, and even by Asiatics. Mithridates used one at the siege of Cyzicus one hundred and fifty feet in height. This most formidable engine was generally made of beams of wood covered on three sides with iron and sometimes with raw hides. They were higher than the walls and all the other fortifications of a besieged place, divided into stories pierced with windows. In and upon them were stationed archers and slingers, and in the lower story was a battering-ram. They also carried scaling-ladders, so that when the wall was cleared, these were placed against the walls. They were placed upon wheels, and brought as near the walls as possible. It was impossible to resist these powerful engines, unless they were burned, or the ground undermined upon which they stood, except by overturning them with stones or iron-shod beams hung from a mast on the wall, or by increasing the height of the wall, or the erection of temporary towers on the wall beside them.

[Sidenote: The advantages of defenders.]

[Sidenote: Ordinary way of capture.]

[Sidenote: Strength and advantage of fortresses.]

Thus there was no ancient fortification capable of withstanding a long siege when the besieged city was, short of defenders or provisions. With equal forces an attack was generally a failure, for the defenders had always a great advantage. But when the number of defenders was reduced, or when famine pressed, the skill and courage of the assailants would ultimately triumph. Some ancient cities made a most obstinate resistance, like Tarentum; Carthage, which stood a siege of four years; Numantia in Spain, and Jerusalem. When cities were of immense size, population, and resources, like Rome when besieged by Alaric, it was easier to take them by cutting off all ingress and egress, so as to produce famine. Tyre was only taken by Alexander by cutting off the harbor. Babylon could not have been taken by Cyrus by assault, since the walls were three hundred and thirty-seven feet high, according to Herodotus, and the ditch too wide for the use of battering-rams. He resorted to an expedient of which the blinded inhabitants of that doomed city never dreamed, which rendered their impregnable fortifications useless. Nor would the Romans have probably prevailed against Jerusalem had not famine decimated and weakened the people. Fortified cities, though scarcely ever impregnable, were yet more in use in ancient than modern times, and greatly delayed the operations of advancing armies. And it was probably the fortified camp of the Romans, which protected an army against surprises and other misfortunes, which gave such efficacy to the legions.

[Sidenote: The Tribunes.]

[Sidenote: The Centurions.]

[Sidenote: Gradation of ranks.]

The chief officers of the legion were the tribunes, and originally there was one in each legion from the three tribes--the Ramnes, Luceres, and Tities. In the time of Polybius the number in each legion was six. Their authority extended equally over the whole legion; but, to prevent confusion, it was the custom for these military tribunes to divide themselves into three sections of two, and each pair undertook the routine duties for two months out of six. They nominated the centurions, and assigned to each the company to which he belonged. These tribunes, at first, were chosen by the commander-in-chief,--by the kings and consuls; but during the palmy days of the republic, when the patrician power was preeminent, they were elected by the people, that is, the citizens. Later they were named half by the Senate and half by the consuls. No one was eligible to this great office who had not served ten years in the infantry or five in the cavalry. They were distinguished by their dress from the common soldier. Next in rank to the tribunes, who corresponded to the rank of brigadiers and colonels in our times, were the centurions, of whom there were sixty in each legion,--men who were more remarkable for calmness and sagacity than for courage and daring valor; men who would keep their posts at all hazards. It was their duty to drill the soldiers, to inspect arms, clothing, and food, to visit the sentinels, and regulate the conduct of the men. They had the power of inflicting corporal punishment. They were chosen for merit solely, until the later ages of the empire, when their posts were bought, as in the English army. These centurions were of unequal rank,--those of the Triarii before those of the Principes, and those of the Principes before those of the Hastati. The first centurion of the first maniple of the Triarii stood next in rank to the tribunes, and had a seat in the military councils, and his office was very lucrative. To his charge was intrusted the eagle of the legion. [Footnote: Liv. xxv. 5; Caes. _B.C._, vi. 6.] As the centurion could rise from the ranks, and rose by regular gradation through the different maniples of the Hastati, Principes, and Triarii, there was great inducement held out to the soldiers. In the Roman legion it would seem that there was a regular gradation of rank although there were but few distinct offices. But the gradation was not determined by length of service, but for merit alone, of which the tribunes were the sole judges. Hence the tribune of a Roman legion had more power than that of a modern colonel. As the tribunes named the centurions, so the centurions appointed their lieutenants, who were called sub-centurions.

[Sidenote: Change in the organization of the legions.]

There was a change in the constitution and disposition of the legion after the time of Marius, until the fall of the republic. The legions were thrown open to men of all grades; they were all armed and equipped alike; the lines were reduced to two, with a space between each cohort, of which there were five in each line; the young soldiers were placed in the rear, and not the van; the distinction between Hastati, Principes, and Triarii ceased; the Velites disappeared, their work being done by the foreign mercenaries; the cavalry ceased to be part of the legion, and became a distinct body; and the military was completely severed from the rest of the state. Formerly no one could aspire to office who had not completed ten years of military service, but in the time of Cicero a man could pass through all the great dignities of the state with a very limited experience of military life. Cicero himself served but one campaign.

[Sidenote: Changes under the emperors.]

[Sidenote: Pay of soldiers.]

Under the emperors, there were still other changes. The regular army consisted of legions and supplementa,--the latter being subdivided into the imperial guards and the auxiliary troops. The auxiliaries (Socii) consisted of troops from the states in alliance with Rome, or those compelled to furnish subsidies. The infantry of the allies was generally more numerous than that of the Romans, while the cavalry was three times as numerous. All the auxiliaries were paid by the state; the infantry received the same pay as the Roman infantry, but the cavalry only two thirds of what was paid to the Roman cavalry. The common foot-soldier received in the time of Polybius three and a half asses a day, equal to about six farthings sterling money; the horseman three times as much. The Praetorian cohorts received twice as much as the legionaries. Julius Caesar allowed about six asses a day as the pay of the legionary, and under Augustus the daily pay was raised to ten asses--little more than four pence per day. Domitian raised the stipend still higher. The soldier, however, was fed and clothed by the government.

[Sidenote: The Praetorian cohort.]

The Praetorian cohort was a select body of troops instituted by Augustus to protect his person, and consisted of ten cohorts, each of one thousand men, chosen from Italy. This number was increased by Vitellius to sixteen thousand, and they were assembled by Tiberius in a permanent camp, which was strongly fortified. They had peculiar privileges, and when they had served sixteen years, received twenty thousand sesterces, or more than one hundred pounds sterling. Each Praetorian had the rank of a centurion in the regular army. Like the body-guard of Louis XIV., they were all gentlemen, and formed gradually a great power, like the janissaries at Constantinople, and frequently disposed of the purple itself. It would thus appear that the centurion only received twice the pay of the ordinary legionary. There was not therefore so much difference in rank between a private and a captain as in our day. There were no aristocratic distinctions in the ancient world so marked as in the modern.

[Sidenote: The guardianship of the camp.]

[Sidenote: The breaking up of the camp.]

Our notice of the Roman legion would be incomplete without allusion to the camp in which the soldier virtually lived. A Roman army never halted for a single night without forming a regular intrenchment capable of holding all the fighting men, the beasts of burden, and the baggage. When the army could not retire, during the winter months, into some city, it was compelled to live in the camp. It was arranged and fortified according to a uniform plan, so that every company and individual had a place assigned. We cannot tell when this practice of intrenchment began; it was matured gradually, like all other things pertaining to the art of war. The system was probably brought to perfection during the wars with Hannibal. Skill in the choice of ground, giving facilities for attack and defense, and for procuring water and other necessities, was of great account with the generals. An area of about five thousand square feet was allowed for a company of infantry, and ten thousand feet for a troop of thirty dragoons. The form of a camp was an exact square, the length of each side being two thousand and seventeen feet. There was a space between the ramparts and the tents of two hundred feet to facilitate the marching in and out of soldiers, and to guard the cattle and booty. The principal street was one hundred feet wide, and was called Principia. The defenses of the camp consisted of a ditch, the earth from which was thrown inwards, and strong palisades of wooden stakes upon the top of the earthwork so formed. The ditch was sometimes fifteen feet deep, and the vallum or rampart ten feet in height. When the army encamped for the first time the tribunes administered an oath to each individual, including slaves, to the effect that they would steal nothing out of the camp. Every morning at daybreak, the centurions and the equites presented themselves before the tents of the tribunes, and the tribunes in like manner presented themselves to the praetorian, to learn the orders of the consuls, which through the centurions were communicated to the soldiers. Four companies took charge of the principal street, to see that it was properly cleaned and watered. One company took charge of the tent of the tribune, a strong guard attended to the horses, and another of fifty men stood beside the tent of the general that he might be protected from open danger and secret treachery. The velites mounted guard the whole night and day along the whole extent of the vallum, and each gate was guarded by ten men. The equites were intrusted with the duty of acting as sentinels during the night, and most ingenious measures were adopted to secure their watchfulness and fidelity. The watchword for the night was given by the commander-in-chief. "On the first signal being given by the trumpet, the tents were all struck and the baggage packed. At the second signal, the baggage was placed upon the beasts of burden; and at the third the whole army began to move. Then the herald, standing at the right hand of the general, demands thrice if they are ready for war, to which they all respond with loud and repeated cheers that they are ready, and for the most part, being filled with martial ardor, anticipate the question, 'and raise their right hands on high with a shout.'" [Footnote: Smith, _Dict. of Ant._, art. _Castra_.]

[Sidenote: Line of March.]

Josephus gives an account of the line of march in which the army of Vespasian entered Galilee. "1. The light-armed auxiliaries and bowmen, advancing to reconnoiter. 2. A detachment of Roman heavy-armed troops, horse and foot. 3. Ten men out of every century or company, carrying their own equipments and the measures of the camp. 4. The baggage of Vespasian and his legati guarded by a strong body of horse. 5. Vespasian himself, attended by his horse-guard and a body of spearmen. 6. The peculiar cavalry of the legion. 7. The artillery dragged by mules. 8. The legati, tribunes, and praefects of cohorts, guarded by a body of picked soldiers. 9. The standards, surrounding the eagle. 10. The trumpeters. 11. The main body of the infantry, six abreast, accompanied by a centurion, whose duty it was to see that the men kept their ranks. 12. The whole body of slaves attached to each legion, driving the mules and beasts of burden loaded with the baggage. 13. Behind all the legions followed the mercenaries. 14. The rear was brought up by a strong body of cavalry and infantry." [Footnote: Josephus, _B. J._, iii. 6, Section 2.]

[Sidenote: How battles were decided.]

From what has come down to us of Roman military life, it appears to have been full of excitement, toil, danger, and hardship. The pecuniary rewards of the soldier were small. He was paid in glory. No profession brought so much honor as the military. And from the undivided attention of a great people to this profession, it was carried to all the perfection which could be attained until the great invention of gunpowder changed the art of war. It was not the number of men employed in the armies which particularly arrests attention, but the spirit and genius which animated them. The Romans loved war, but so reduced it to a science that it required comparatively small armies to conquer the world. Sulla defeated Mithridates with only thirty thousand men, while his adversary marshaled against him over one hundred thousand; and Caesar had only ten legions to effect the conquest of Gaul, and none of these were of Italian origin. At the great decisive battle of Pharsalia, when most of the available forces of the empire were employed, on one side or the other, Pompey commanded a legionary army of forty-five thousand men; and the cavalry amounted to seven thousand more, but among them were included the flower of the Roman nobility. The auxiliary force has not been computed, although it was probably numerous. Caesar had under him only twenty-two thousand of legionaries and one thousand cavalry. But every man in both armies was prepared to conquer or die. The forces were posted on the open plain, and the battle was really a hand-to-hand encounter, in which the soldiers, after hurling their lances, fought with their swords chiefly. And when the cavalry of Pompey rushed upon the legionaries of Caesar, no blows were wasted on the mailed panoply of the mounted Romans, but were aimed at the face alone, as that alone was unprotected. The battle was decided by the coolness, bravery, and discipline of veterans, inspired by the genius of the greatest general of antiquity. Less than one hundred thousand men, in all probability, were engaged in one of the most memorable conflicts which the world has seen.

[Sidenote: Gradual organization of military power.]

[Sidenote: Magnanimity of the early generals.]

Thus it was, by unparalleled heroism in war, and a uniform policy in government, that Rome became the mistress of the world. The Roman conquests have never been surpassed, for they were retained until the empire fell. I wish that I could have dwelt on these conquests more in detail, and presented more fully the brilliant achievements of individuals. It took nearly two hundred years, after the expulsion of the kings, to regain supremacy over the neighboring people, and another century to conquer Italy. The Romans did not contend with regular armies until they were brought in conflict with the king of Epirus and the phalanx of the Greeks, "which improved their military tactics, and introduced between the combatants those mutual regards of civilized nations which teach men to honor their adversaries, to spare the vanquished, and to lay aside wrath when the struggle is ended." In the fifth century of her existence, the republic appears in peculiar splendor. Military chieftains do not transcend their trusts; the aristocracy are equally distinguished for exploits and virtues; the magistrates maintain simplicity of manners and protect the rights of the citizens; the citizens are self-sacrificing and ever ready to obey the call to arms, laying aside great commands and retiring poor to private stations. Marcus Valerius Corvus, after filling twenty-one curule offices, returns to agricultural life; Marcus Curius Dentatus retains no part of the rich spoils or the Sabines; Fabricius rejects the gold of the Samnites and the presents of Pyrrhus. The most trustworthy are elevated to places of dignity and power. Senators mingle in the ranks of the legions, and eighty of them die on the field of Cannae. Discipline is enforced to cruelty, and Manlius Torquatus punishes with death a disobedient son. Soldiers who desert the field are decimated or branded with dishonor. Faith is kept even with enemies, and Regulus returns a voluntary prisoner to his deadly enemies.

[Sidenote: Results of different wars.]

After the consolidation of Roman power in Italy, it took one hundred and fifty years more only to complete the conquest of the world--of Northern Africa, Spain, Gaul, Illyria, Epirus, Greece, Macedonia, Asia Minor, Pontus, Syria, Egypt, Bithynia, Cappadocia, Pergamus, and the islands of the Mediterranean. The conquest of Carthage left Rome without a rival in the Mediterranean, and promoted intercourse with the Greeks. The Illyrian wars opened to the Romans the road to Greece and Asia, and destroyed the pirates of the Adriatic. The invasion of Cisalpine Gaul, now that part of Italy which is north of the Apennines, protected Italy from the invasion of barbarians. The Macedonian War against Philip put Greece under the protection of Rome, and that against Antiochus laid Syria at her mercy; and when these kingdoms were reduced to provinces, the way was opened to further conquests in the East, and the Mediterranean became a Roman lake.

[Sidenote: Effect of Roman conquests on society.]

[Sidenote: Degeneracy of morals undermines military power.]

But these conquests introduce luxury, wealth, pride, and avarice, with arts, refinements, and literature. These degrade while they elevate. Civilization becomes the alternate triumph of good and evil influences, and a doubtful boon. Successful war creates great generals, and founds great families, increases slavery, and promotes inequalities. Demagogues arise who seduce and deceive the people, and they enroll themselves under the standards of their idols. Rome is governed by an oligarchy of military chieftains, and has become more aristocratic and more democratic at the same time. The people gain rights, only to yield to the supremacy of demagogues. The Senate is humbled, but remains the ascendant power, for generals compose it, and those who have held great offices. Meanwhile the great generals struggle for supremacy. Civil wars follow in the train of foreign conquests. Marius, Sulla, Pompey, Julius, Antony, Augustus, sacrifice the state to their ambition. Good men lament, and protest, and hide themselves. Cato, Cicero, Brutus, speak in vain. Degenerate morals keep pace with civil contests. Rome revels in the spoils of all kingdoms and countries, is intoxicated with power, becomes cruel and tyrannical, and, after yielding up the lives of citizens to fortunate generals, yields at last her liberties, and imperial despotism begins its reign,--hard, immovable, resolute,--under which genius is crushed, and life becomes epicurean, but under which property and order are preserved. The regime is bad; but it is a change for the better. War has produced its fruits. It has added empire, but undermined prosperity; it has created a great military monarchy, but destroyed liberty; it has brought wealth, but introduced inequalities; it has filled the city with spoils, but sown the vices of self-interest. The machinery is perfect, but life has fled. It is henceforth the labor of emperors to keep together their vast possessions with this machinery, which at last wears out, since there is neither genius to repair it nor patriotism to work it. It lasts three hundred years, but is broken to pieces by the Goths and Vandals.

The highest authority in relation to the construction of an army is Polybius, who was contemporary with Scipio, at a period when Roman discipline was most perfect. A fragment from his sixth book gives considerable information. A chapter of Livy--the eighth--is also very much prized. Salmasius and Lepsius have also written learned treatises. Smith's Dictionary, which is full of details in every thing pertaining to the weapons, the armor, the military engines, the rewards and punishments of the soldiers, refers to Folard's _Commentaire_, to _Memoires Militaires sur les Grecs et les Remains_, by Guischard, and to the _Histoire des Campagnes d'Hannibal en Italie_, by Vaudencourt. Tacitus, Sallust, Livy, Dion Cassius, Pliny, and Caesar reveal incidentally much that we wish to know. Gibbon gives some important facts in his first chapter. The subject of ancient machines is treated by Folard's Commentary attached to his translation of Polybius. Caesar's Commentaries give us, after all, the liveliest idea of the military habits and tactics of the Romans. Josephus describes with great vividness the siege of Jerusalem. The article on _Exercitus_, by Prof. Ramsay, in Smith's Dictionary, is the fullest I have read pertaining to the structure of a Roman army.

For the narrative of wars, the reader is referred to ordinary Roman histories--to Livy and Caesar especially; to Niebuhr, Mommsen, Arnold, and Liddell. See also Durny, _Hist. des Romains;_ Michelet, _Hist. de Rom._ Napoleon's History of Caesar should be read, admirable in style, and interesting in matter, although a sophistical defense of usurpation.
