[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 mult.i.tudes, 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 inst.i.tutions. 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 inst.i.tutions 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 b.l.o.o.d.y battles, the fearful ma.s.sacres, 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 a.s.sa.s.sin'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 n.o.blest 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 const.i.tution of his country. He was virtually the supreme ruler of the world. In the brief period which pa.s.sed 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 n.o.bles 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 a.s.sa.s.sination. 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 b.l.o.o.d.y catalogue. After his pa.s.sage 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 const.i.tution. 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 pa.s.sed under the rule of Caesar. The Temple of Ja.n.u.s 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 inst.i.tutions 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 a.s.saults 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 t.i.tus. 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 n.o.bles 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: 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 cuira.s.s was generally made of metal, and sometimes was highly ornamented. Chain-mail was also used. The greaves were of bronze or bra.s.s, 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 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 hors.e.m.e.n.
