Training of Roman Soldiers

In the Roman Republic, all Romans citizens were required to participate in the military. In the Roman Empire, when a professional army was in place, many soldiers were non-citizen volunteers who signed up in return for good pay, housing, status and booty from conquests. When they were discharged they became citizens. Even barbarians were recruited with these promises. The army’s greatest expense was its payroll. The expression "worth their salt" comes from Rome where soldiers were paid a salarium (salary) to buy salt.

The Romans managed create a professional army by paying soldiers enough so they were no longer tied to the land. Legionnaires were given a daily stipend. They served six to twenty years (averaging about ten). The completion of military service provided the soldier with citizenship not only for himself but for his entire family. The legionnaires were forbidden to marry, though some did illegally, and their families often "attached themselves to the camps." [Source: "History of Warfare" by John Keegan, Vintage Books]

Romans soldiers carried 30 kilograms loads. To get a sense of what it was really like to be a Roman soldier. German historian Marcus Junkel and a handful of colleagues donned Roman garb and rode on horseback over the Alps, along the Danube, and beside the Mediterranean. Perhaps the most important thing they learned from the experience was to be careful with horses and weapons. One time a horse fell on him and broke his shinbone. Another time he fell on javelin that pierced his neck. [National Geographic Geographica, October 1993."

Selection of Recruits for the Roman Army

Flavius Vegetius Renatus wrote in “De Re Militari”: “To treat our subject with some method, we shall first examine what provinces or nations are to be preferred for supplying the armies with recruits. It is certain that every country produces both brave men and cowards; but it is equally as certain that some nations are naturally more warlike than others, and that courage, as well as strength of body, depends greatly upon the influence of the different climates.

“We shall next examine whether the city or the country produces the best and most capable soldiers. No one, I imagine, can doubt that the peasants are the most fit to carry arms for they from their infancy have been exposed to all kinds of weather and have been brought up to the hardest labor. They are able to endure the greatest heat of the sun, are unacquainted with the use of baths, and are strangers to the other luxuries of life. They are simple, content with little, inured to all kinds of fatigue, and prepared in some measure for a military life by their continual employment in their country-work, in handling the spade, digging trenches and carrying burdens. In cases of necessity, however, they are sometimes obliged to make levies in the cities. And these men, as soon as enlisted, should be taught to work on entrenchments, to march in ranks, to carry heavy burdens, and to bear the sun and dust. Their meals should be coarse and moderate; they should be accustomed to lie sometimes in the open air and sometimes in tents. After this, they should be instructed in the use of their arms. And if any long expedition is planned, they should be encamped as far as possible from the temptations of the city. By these precautions their minds, as well as their bodies, will properly be prepared for the service.

“I realize that in the first ages of the Republic, the Romans always raised their armies in the city itself, but this was at a time when there were no pleasures, no luxuries to enervate them. The Tiber was then their only bath, and in it they refreshed themselves after their exercises and fatigues in the field by swimming. In those days the same man was both soldier and farmer, but a farmer who, when occasion arose, laid aside his tools and put on the sword. The truth of this is confirmed by the instance of Quintius Cincinnatus, who was following the plow when they came to offer him the dictatorship. The chief strength of our armies, then, should be recruited from the country. For it is certain that the less a man is acquainted with the sweets of life, the less reason he has to be afraid of death.

“In choosing recruits regard should be given to their trade. Fishermen, fowlers, confectioners, weavers, and in general all whose professions more properly belong to women should, in my opinion, by no means be admitted into the service. On the contrary, smiths, carpenters, butchers, and huntsmen are the most proper to be taken into it. On the careful choice of soldiers depends the welfare of the Republic, and the very essence of the Roman Empire and its power is so inseparably connected with this charge, that it is of the highest importance not to be intrusted indiscriminately, but only to persons whose fidelity can be relied on. The ancients considered Sertorius' care in this point as one of the most eminent of his military qualifications. The soldiery to whom the defense of the Empire is consigned and in whose hands is the fortune of war, should, if possible, be of reputable families and unexceptionable in their manners. Such sentiments as may be expected in these men will make good soldiers. A sense of honor, by preventing them from behaving ill, will make them victorious.

“But what good can be expected from a man by nature a coward, though ever so well disciplined or though he has served ever so many campaigns? An army raised without proper regard to the choice of its recruits was never yet made good by length of time; and we are now convinced by fatal experience that this is the source of all our misfortunes. So many defeats can only be imputed to the effects of a long peace which has made us negligent and careless in the choice of our levies and to the inclination so prevalent among the better sort in preferring the civil posts of the government to the profession of arms and to the shameful conduct of the superintendents, who, through interest or connivance, accept many men which those who are obliged to furnish substitutes for the army choose to send, and admit such men into the service as the masters themselves would not even keep for servants. Thus it appears that a trust of such importance should be committed to none but men of merit and integrity.”

A Roman soldier's enlistment document from Egypt reads: “Enlistment Preliminaries from Egypt, Oxyrhynchus, A.D. 51: Copy of a release. Year 12 of Emperor Tiberius Claudius Caesar Augustus Germanicus, Pharmuthi 29, Augustan. Released by Gnaeus Vergilius Capito, Praefectus of both ( Egypt and Alexandria? ): Trypho son of Dionysios, weaver, from the Metropolis of Oxyrhynchus, suffering from cataract impairing his vision. Examined and certified in Alexandria. [Source: California State University, Northridge (CSUN) ]

Desirable Qualities in Roman Army Recruits

Flavius Vegetius Renatus wrote in “De Re Militari”: “Proper Age for Recruits: If we follow the ancient practice, the proper time for enlisting youth into the army is at their entrance into the age of puberty. At this time instructions of every kind are more quickly imbibed and more lastingly imprinted on the mind. Besides this, the indispensable military exercises of running and leaping must be acquired before the limbs are too much stiffened by age. For it is activity, improved by continual practice, which forms the useful and good soldier. Formerly, says Sallust, the Roman youth, as soon as they were of an age to carry arms, were trained in the Strictest manner in their camps to all the fatigues and exercises of war. For it is certainly better that a soldier, perfectly disciplined, should, through emulation, repine at his not being yet arrived at a proper age for action, than have the mortification of knowing it is past. A sufficient time is also required for his instruction in the different branches of the service. It is no easy matter to train the horse or foot archer, or to form the legionary soldier to every part of the drill, to teach him not to quit his post, to keep ranks, to take a proper aim and throw his missile weapons with force, to dig trenches, to plant palisades, how to manage his shield, glance off the blows of the enemy, and how to parry a stroke with dexterity. A soldier, thus perfect in his business, so far from showing any backwardness to engage, will be eager for an opportunity of signaling himself.

Etext version by Mads Brevik (2001)]

“Their Size: We find the ancients very fond of procuring the tallest men they could for the service, since the standard for the cavalry of the wings and for the infantry of the first legionary cohorts was fixed at six feet, or at least five feet ten inches. These requirements might easily be kept up in those times when such numbers followed the profession of arms and before it was the fashion for the flower of Roman youth to devote themselves to the civil offices of state. But when necessity requires it, the height of a man is not to be regarded so much as his strength; and for this we have the authority of Homer, who tells us that the deficiency of stature in Tydeus was amply compensated by his vigor and courage.

“Signs of Desirable Qualities: Those employed to superintend new levies should be particularly careful in examining the features of their faces, their eyes, and the make of their limbs, to enable them to form a true judgment and choose such as are most likely to prove good soldiers. For experience assures us that there are in men, as well as in horses and dogs, certain signs by which their virtues may be discovered. The young soldier, therefore, ought to have a lively eye, should carry his head erect, his chest should be broad, his shoulders muscular and brawny, his fingers long, his arms strong, his waist small, his shape easy, his legs and feet rather nervous than fleshy. When all these marks are found in a recruit, a little height may be dispensed with, since it is of much more importance that a soldier should be strong than tall.”

Military Mark Branded on a Roman Solider

The military mark was imprinted on the hands of the soldiers, either with a hot iron, or in some other manner. It was indelible. Flavius Vegetius Renatus wrote in “De Re Militari”: “The recruit, however, should not receive the military mark as soon as enlisted. He must first be tried if fit for service; whether he has sufficient activity and strength; if he has capacity to learn his duty; and whether he has the proper degree of military courage. For many, though promising enough in appearance, are found very unfit upon trial. These are to be rejected and replaced by better men; for it is not numbers, but bravery which carries the day. [Source: De Re Militari (Military Institutions of the Romans) by Flavius Vegetius Renatus (died A.D. 450), written around A.D. 390. translated from the Latin by Lieutenant John Clarke Text British translation published in 1767. Etext version by Mads Brevik (2001)]

“After their examination, the recruits should then receive the military mark, and be taught the use of their arms by constant and daily exercise. But this essential custom has been abolished by the relaxation introduced by a long peace. We cannot now expect to find a man to teach what he never learned himself. The only method, therefore, that remains of recovering the ancient customs is by books, and by consulting the old historians. But they are of little service to us in this respect, as they only relate the exploits and events of wars, and take no notice of the objects of our present enquiries, which they considered as universally known.

“Names of Soldiers Inscribed on Their Shields: Lest the soldiers in the confusion of battle should be separated from their comrades, every cohort had its shields painted in a manner peculiar to itself. The name of each soldier was also written on his shield, together with the number of the cohort and century to which he belonged. From this description we may compare the legion, when in proper order, to a well fortified city as containing within itself every thing requisite in war, wherever it moved. It was secure from any sudden attempt or surprise of an enemy by its expeditious method of entrenching its camp even in the open plains and it was always provided with troops and arms of every kind. To be victorious, therefore, over our enemies in the field, we must unanimously supplicate heaven to dispose the Emperor to reform the abuses in raising our levies and to recruit our legions after the method of the ancients.

“The same care in choosing and instructing our young soldiers in all military exercises and drills will soon make them equal to the old Roman troops who subdued the whole world. Nor let this alteration and loss of ancient discipline in any way affect Your Majesty, since it is a happiness reserved for You alone both to restore the ancient ordinances and establish new ones for the public welfare. Every work before the attempt carries in it an appearance of difficulty; but in this case, if the levies are made by careful and experienced officers, an army may be raised, disciplined and rendered fit for service in a very short time; for the necessary expenses once provided, diligence soon effects whatever it undertakes.”

Training of a Roman Soldiers

Flavius Vegetius Renatus wrote in “De Re Militari”: “The first thing the soldiers are to be taught is the military step, which can only be acquired by constant practice of marching quick and together. Nor is anything of more consequence either on the march or in the line than that they should keep their ranks with the greatest exactness. For troops who march in an irregular and disorderly manner are always in great danger of being defeated. They should march with the common military step twenty miles in five summer-hours, and with the full step, which is quicker, twenty-four miles in the same number of hours. If they exceed this pace, they no longer march but run, and no certain rate can be assigned.

“But the young recruits in particular must be exercised in running, in order to charge the enemy with great vigor; occupy, on occasion, an advantageous post with greater expedition, and prevent the enemy in their designs upon the same; that they may, when sent to reconnoiter, advance with speed, return with greater celerity and more easily come up with the enemy in a pursuit.

“Leaping is another very necessary exercise, to enable them to pass ditches or embarrassing eminences of any kind without trouble or difficulty. There is also another very material advantage to be derived from these exercises in time of action; for a soldier who advances with his javelin,.running and leaping, dazzles the eyes of his adversary, strikes him with terror, and gives him the fatal stroke before he has time to put himself on his defense. Sallust, speaking of the excellence of Pompey the Great in these particulars, tells us that he disputed the superiority in leaping with the most active, in running with the most swift, and in exercises of strength with the most robust. Nor would he ever have been able to have opposed Serrorius with success, if he had not prepared both himself and his soldiers for action by continual exercises of this sort.

“The Post Exercise: We are informed by the writings of the ancients that, among their other exercises, they had that of the post. They gave their recruits round bucklers woven with willows, twice as heavy as those used on real service, and wooden swords double the weight of the common ones. They exercised them with these at the post both morning and afternoon. This is an invention of the greatest use, not only to soldiers, but also to gladiators. No man of either profession ever distinguished himself in the circus or field of battle, who was not perfect in this kind of exercise. Every soldier, therefore, fixed a post firmly in the ground, about the height of six feet. Against this, as against a real enemy, the recruit was exercised with the above mentioned arms, as it were with the common shield and sword, sometimes aiming At the head or face, sometimes at the sides, at others endeavoring to strike at the thighs or legs. He was instructed in what manner to advance and retire, and in short how to take every advantage of his adversary; but was thus above all particularly cautioned not to lay himself open to his antagonist while aiming his stroke at him.

“The Drill Called Armatura: The new levies also should be taught by the masters at arms the system of drill called armatura, as it is still partly kept up among us. Experience even at this time convinces us that soldiers, perfect therein, are of the most service in engagements. And they afford certain proofs of the importance and effects of discipline in the difference we see between those properly trained in this branch of drill and the other troops. The old Romans were so conscious of its usefulness that they rewarded the masters at arms with a double allowance of provision. The soldiers who were backward in this drill were punished by having their allowance in barley. Nor did they receive it as usual, in wheat, until they had, in the presence of the prefect, tribunes, or other principal officers of the legion, showed sufficient proofs of their knowledge of every part of their study.

“No state can either be happy or secure that is remiss and negligent in the discipline of its troops. For it is not profusion of riches or excess of luxury that can influence our enemies to court or respect us. This can only be effected by the terror of our arms. It is an observation of Cato that. misconduct in the common affairs of life may be retrieved, but that it is quite otherwise in war, where errors are fatal and without remedy, and are followed by immediate punishment. For the consequences of engaging an enemy, without skill or courage, is that part of the army is left on the field of battle, and those who remain receive such an impression from their defeat that they dare not afterwards look the enemy in the face.”

Swimming, Vaulting and Carrying Burdens

Flavius Vegetius Renatus wrote in “De Re Militari”: “To Learn to Swim: Every young soldier, without exception, should in the summer months be taught to swim; for it is sometimes impossible to pass rivers on bridges, but the flying and pursuing army both are often obliged to swim over them. A sudden melting of snow or fall of rain often makes them overflow their banks, and in such a situation, the danger is as great from ignorance in swimming as from the enemy. The ancient Romans, therefore, perfected in every branch of the military art by a continued series of wars and perils, chose the Field of Mars as the most commodious for their exercises on account of its vicinity to the Tiber, that the youth might therein wash off the sweat and dust, and refresh themselves after their fatigues by swimming. The cavalry also as well as the infantry, and even the horses and the servants of the army should be accustomed to this exercise, as they are all equally liable to the same accidents. [Source: De Re Militari (Military Institutions of the Romans) by Flavius Vegetius Renatus (died A.D. 450), written around A.D. 390. translated from the Latin by Lieutenant John Clarke Text British translation published in 1767. Etext version by Mads Brevik (2001)]

“To Be Taught to Vault: The ancients strictly obliged both the veteran soldiers and recruits to a constant practice of vaulting. It has indeed reached our cimes, although little regard is paid to it at present. They had wooden horses for that purpose placed in winter under cover and in summer in the field. The young soldiers were taught to vault on them at first without arms, afterwards completely armed. And such was their attention to this exercise that they were accustomed to mount and dismount on either side indifferently, with their drawn swords or lances in their hands. By assiduous practice in the leisure of peace, their cavalry was brought to such perfection of discipline that they mounted their horses in an instant even amidst the confusion of sudden and unexpected alarms.

“And to Carry Burdens: To accustom soldiers to carry burdens is also an essential part of discipline. 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. Nor will they find this troublesome when inured to it by custom, which makes everything easy.

“Our troops in ancient times were a proof of this, and Virgil has remarked it in the following lines:
The Roman soldiers, bred in war's alarms,
Bending with unjust loads and heavy arms,
Cheerful their toilsome marches undergo,
And pitch their sudden camp before the foe.”

Weapons Training for Roman Soldiers

Flavius Vegetius Renatus wrote in “De Re Militari”: “Not to Cut, but to Thrust with the Sword: They were likewise taught not to cut but to thrust with their swords. For the Romans not only made a jest of those who fought with the edge of that weapon, but always found them an easy conquest. A stroke with the edges, though made with ever so much force, seldom kills, as the vital parts of the body are defended both by the bones and armor. On the contrary, a stab, though it penetrates but two inches, is generally fatal. Besides in the attitude of striking, it is impossible to avoid exposing the right arm and side; but on the other hand, the body is covered while a thrust is given, and the adversary receives the point before he sees the sword. This was the method of fighting principally used by the Romans, and their reason for exercising recruits with arms of such a weight at first was, that when they came to carry the common ones so much lighter, the greater difference might enable them to act with greater security and alacrity in time of action. [Source: De Re Militari (Military Institutions of the Romans) by Flavius Vegetius Renatus (died A.D. 450), written around A.D. 390. translated from the Latin by Lieutenant John Clarke Text British translation published in 1767. Etext version by Mads Brevik (2001) ]

“The Use of Missile Weapons: Besides the aforementioned exercise of the recruits at the post, they were furnished with javelins of greater weight than common, which they were taught to throw at the same post. And the masters at arms were very careful to instruct them how to cast them with a proper aim and force. This practice strengthens the arm and makes the soldier a good marksman.

“The Use of the Bow: A third or fourth of the youngest and fittest soldiers should also be exercised at the post with bows and arrows made for that purpose only. The masters for this branch must be chosen with care and must apply themselves diligently to teach the men to hold the bow in a proper position, to bend it with strength, to keep the left hand steady. to draw the right with skill, to direct both the attention and the eye to the object, and to take their aim with equal certainty either on foot or on horseback. But this is not to be acquired without great application, nor to be retained without daily exercise and practice.

“The utility of good archers in action is evidently demonstrated by Cato in his treatise on military discipline. To the institution of a body of troops of this sort Claudius owed his victory over an enemy who, till that time, had constantly been superior to him. Scipio Africanus, before his battle with the Numantines, who had made a Roman army ignominiously pass under the yoke, thought he could have no likelihood of success except by mingling a number of select archers with every century.

“The Sling: Recruits are to be taught the art of throwing stones both with the hand and sling. The inhabitants of the Balearic Islands are said to have been the inventors of slings, and to have managed them with surprising dexterity, owing to the manner of bringing up their children. The children were not allowed to have their food by their mothers till they had first struck it with their sling. Soldiers, notwithstanding their defensive armor, are often more annoyed by the round stones from the sling than by all the arrows of the enemy. Stones kill without mangling the body, and the contusion is mortal without loss of blood. It is universally known the ancients employed slingers in all their engagements. There is the greater reason for instructing all troops, without exception, in this exercise, as the sling cannot be reckoned any incumbrance, and often is of the greatest service, especially when they are obliged to engage in stony places, to defend a mountain or an eminence, or to repulse an enemy at the attack of a castle or city.

“The Loaded Javelin: The exercise of the loaded javelins, called martiobarbuli, must not be omitted. We formerly had two legions in lllyricum, consisting of six thousand men each, which from their extraordinary dexterity and skill in the use of these weapons were discingui.shed by the same appellation. They supported for a long time the weight of all the wars and distinguished themselves so remarkably that the Emperors Diocletian and Maximian on their accession honored them with the titles of Jovian and Herculean and preferred them before all the other legions. Every soldier carries five of these javelins in the hollow of his shield. And thus the legionary soldiers seem to supply the place of archers, for they wound both the men and horses of the enemy before they come within reach of the common missile weapons.”

Roman Discipline and Maintaining Fitness

Flavius Vegetius Renatus wrote in “De Re Militari”: “No part of drill is more essential in action than for soldiers to keep their ranks with the greatest exactness, without opening or closing too much. Troops too much crowded can never fight as they ought, and only embarrass one another. If their order is too open and loose, they give the enemy an opportunity of penetrating. Whenever this happens and they are attacked in the rear, universal disorder and confusion are inevitable. [Source: De Re Militari (Military Institutions of the Romans) by Flavius Vegetius Renatus (died A.D. 450), written around A.D. 390. translated from the Latin by Lieutenant John Clarke Text British translation published in 1767. Etext version by Mads Brevik (2001)]

Recruits should therefore be constantly in the field, drawn up by the roll and formed at first into a single rank. They should learn to dress in a straight line and to keep an equal and just distance between man and man. They must then be ordered to double the rank, which they must perform very quickly, and instantly cover their file leaders. In the next place, they are to double again and form four deep. And then the triangle or, as it is commonly called, the wedge, a disposition found very serviceable in action. They must be taught to form the circle or orb; for well-disciplined troops, after being broken by the enemy, have thrown themselves into this position and have thereby prevented the total rout of the army. These evolutions, often practiced in the field of exercise, will be found easy in execution on actual service.

“Monthly Marches: It was a constant custom among the old Romans, confirmed by the Ordinances of Augustus and Hadrian, to exercise both cavalry and infantry three times in a month by marches of a certain length. The foot were obliged to march completely armed the distance of ten miles from the camp and return, in the most exact order and with the military step which they changed and quickened on some part of the march. Their cavalry likewise, in troops and properly armed, performed the same marches and were exercised at the same time in their peculiar movement and evolutions; sometimes, as if pursuing the enemy, sometimes retreating and returning again with greater impetuosity to the charge. They made these marches not in plain and even ground only, but both cavalry and infantry were ordered into difficult and uneven places and to ascend or descend mountains, to prepare them for all kinds of accidents and familiarize them with the different maneuvers that the various situations of a country may require.
