ROMAN BATTLE TACTICS AND SEASONALITY OF WAR
The Romans fought differently than the Greeks. Instead of being organized into tight ranks like the Greeks, Roman soldiers organized themselves into small more maneuverable groups of soldiers called maniples, or handfuls. And instead of driving forward with thrusting spears and 70 pounds of armor, the Romans adopted light oblong shields and breast plates, and attacked with swords after unleashing a flurry of javelins, When they advanced disciplined foot soldiers marched relentlessly forward in centuries (blocks of shielded men). The Roman cavalry, which played a fairly big role in the 4th century B.C., was later reduced to auxiliary status. [Source: "History of Warfare" by John Keegan, Vintage Books]
“During the Romans’ early history, the logistical challenges of conducting a war meant that the Romans only fought between sowing and harvest (during the summer). Rome was an agriculture-based economy, and the movement of troops during winter was highly demanding. The first recorded continuation of war into the winter by the Romans took place in 396 B.C. during the siege of the Etruscan city of Veii. [Source: Cristian Violatti, Listverse, September 4, 2016 ]
“According to Livy (History of Rome, 5.6), if a war was not over by the end of summer, “our soldiers must wait through the winter.” He also mentioned a curious way that many soldiers chose to spend the time during the long waiting: “The pleasure of hunting carries men off through snow and frost to the mountains and the woods.”.
In case of war in the Republican Era, it was customary to raise four legions, two for each consul. Each legion was composed of thirty maniples, or companies, of heavy-armed troops,—twenty maniples consisting of one hundred and twenty men each, and ten maniples of sixty men each,—making in all three thousand heavy-armed troops. There were also twelve hundred light-armed troops, not organized in maniples. The whole number of men in a legion was therefore forty-two hundred. To each legion was usually joined a body of cavalry, numbering three hundred men. After the reduction of Latium and Italy, the allied cities were also obliged to furnish a certain number of men, according to the terms of the treaty.

In ancient times the Romans fought in the manner of the Greek phalanx, in a solid square. This arrangement was well suited to withstand an attack on a level plain, but it was not adapted to aggressive warfare. About the time of Camillus, the Romans introduced the more open order of “maniples.” When drawn up in order of battle, the legion was arranged in three lines: first, the hastati, made up of young men; second, the principes, composed of the more experienced soldiers; and third, the triarii, which comprised the veterans, capable of supporting the other two lines. Each line was composed of ten maniples, those of the first two lines consisting of one hundred and twenty men each, and those of the third line consisting of sixty men each; the maniples, or companies, in each line were so arranged that they were opposite the spaces in the next line.
This arrangement enabled the companies in front to retreat into the spaces in the rear, or the companies in the rear to advance to the spaces in front. Behind the third line usually fought the light-armed and less experienced soldiers (rorarii and accensi). Each maniple carried its own ensign; and the legion carried a standard surmounted with a silver eagle. \~\

Drawing up a Legion in Order of Battle
Flavius Vegetius Renatus (died A.D. 450) wrote in “De Re Militari” (“Military Institutions of the Romans”): “We shall exemplify the manner of drawing up an army in order of battle in the instance of one legion, which may serve for any number. The cavalry are posted on the wings. The infantry begin to form on a line with the :first cohort on the right. The second cohort draws up on the left of the first; the third occupies the center; the fourth is posted next; and the fifth closes the left flank. The ordinarii, the other officers and the soldiers of the first line, ranged before and round the ensigns, were called the principes. They were all heavy armed troops and had helmets, cuirasses, greaves, and shields. Their offensive weapons were large swords, called spathae, and smaller ones called semispathae together with five loaded javelins in the concavity of the shield, which they threw at the first charge. They had likewise two other javelins, the largest of which was composed of a staff five feet and a half long and a triangular head of iron nine inches long. This was formerly called the pilum, but now it is known by the name of spiculum. The soldiers were particularly exercised in the use of this weapon, because when thrown with force and skill it often penetrated the shields of the foot and the cuirasses of the horse. The other javelin was of smaller size; its triangular point was only five inches long and the staff three feet and one half. It was anciently called verriculum but now verutum. [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) digitalattic.org]
“The first line, as I said before, was composed of the principes; the hastati formed the second and were armed in the same manner. In the second line the sixth cohort was posted on the right flank, with the seventh on its left; the eighth drew up in the center; the ninth was the next; and the tenth always closed the left flank. In the rear of these two lines were the ferentarii, light infantry and the troops armed with shields, loaded javelins, swords and common missile weapons, much in the same manner as our modern soldiers. This was also the post of the archers who had helmets, cuirasses, swords, bows and arrows; of the slingers who threw stones with the common sling or with the fustibalus; and of the tragularii who annoyed the enemy with arrows from the manubalistae or arcubalistae.
“In the rear of all the lines, the triarii, completely armed, were drawn up. They had shields, cuirasses, helmets, greaves, swords, daggers, loaded javelins, and two of the common missile weapons. They rested during the acnon on one knee, so that if the first lines were obliged to give way, they might be fresh when brought up to the charge, and thereby retrieve what was lost and recover the victory. All the ensigns though, of the infantry, wore cuirasses of a smaller sort and covered their helmets with the shaggy skins of beasts to make themselves appear more terrible to the enemy. But the centurions had complete cuirasses, shields, and helmets of iron, the crest of which, placed transversely thereon, were ornamented with silver that they might be more easily distinguished by their respective soldiers.
“The following disposition deserves the greatest attention. In the beginning of an engagement, the first and second lines remained immovable on their ground, and the trairii in their usual positions. The light-armed troops, composed as above mentioned, advanced in the front of the line, and attacked the enemy. If they could make them give way, they pursued them; but if they were repulsed by superior bravery or numbers, they retired behind their own heavy armed infantry, which appeared like a wall of iron and renewed the action, at first with their missile weapons, then sword in hand. If they broke the enemy they never pursued them, least they should break their ranks or throw the line into confusion, and lest the enemy, taking advantage of their disorder, should return to the attack and destroy them without difficulty. The pursuit therefore was entirely left to the light-armed troops and the cavalry. By these precautions and dispositions the legion was victorious without danger, or if the contrary happened, was preserved without any considerable loss, for as it is not calculated for pursuit, it is likewise not easily thrown into disorder.
Roman Marches in the Neighborhood of the Enemy
Flavius Vegetius Renatus wrote in “De Re Militari”: “It is asserted by those who have made the profession their study that an army is exposed to more danger on marches than in battles. In an engagement the men are properly armed, they see their enemies before them and come prepared to fight. But on a march the soldier is less on his guard, has not his arms always ready and is thrown into disorder by a sudden attack or ambuscade. A general, therefore, cannot be too careful and diligent in taking necessary precautions to prevent a surprise on the march and in making proper dispositions to repulse the enemy, in case of such accident, without loss.

from Trajan's Column
“In the first place, he should have an exact description of the country that is. the seat of war, in which the distances of places specified by the number of miles, the nature of the roads, the shortest routes, by-roads, mountains and rivers, should be correctly inserted. We are told that the greatest generals have carried their precautions on this head so far that, not satisfied with the simple description of the country wherein they were engaged, they caused plans to be taken of it on the spot, that they might regulate their marches by the eye with greater safety. A general should also inform himself of all these particulars from persons of sense and reputation well acquainted with the country by examining them separately at first, and then comparing their accounts in order to come at the truth with certainty.
“If any difficulty arises about the choice of roads, he should procure proper and skillful guides. He should put them under a guard and spare neither promises nor threat to induce them to be faithful. They will acquit themselves well when they know it is impossible to escape and are certain of being rewarded for their fidelity or punished for their perfidy. He must be sure of their capacity and experience, that the whole army be not brought into danger by the errors of two or three persons. For sometimes the common sort of people imagine they know what they really do not, and through ignorance promise more than they can perform.
“But of all precautions the most important is to keep entirely secret which way or by what route the army is to march. For the security of an expedition depends on the concealment of all motions from the enemy. The figure of the Minotaur was anciently among the legionary ensigns, signifying that this monster, according to the fable, was concealed in the most secret recesses and windings of the labyrinth, just as the designs of a general should always be impenetrable. When the enemy has no intimation of a march, it is made with security; but as sometimes the scouts either suspect or discover the decampment, or traitors or deserters give intelligence thereof, it will be proper to mention the method of acting in case of an attack on the march.
“The general, before he puts his troops in motion, should send out detachments of trusty and experienced soldiers well mounted, to reconnoiter the places through which he is to march, in front, in rear, and on the right and left, lest he should fall into ambuscades. The night is safer and more advantageous for your spies to do their business in than day, for if they are taken prisoners, you have, as it were, betrayed yourself. After this, the cavalry should march off first, then the infantry; the baggage, bat horses, servants and carriages follow in the center; and part of the best cavalry and infantry come in the rear, since it is oftener attacked on a march than the front. The flanks of the baggage, exposed to frequent ambuscades, must also be covered with a sufficient guard to secure them. But above all, the part where the enemy is most expected must be reinforced with some of the best cavalry, light infantry and foot archers.
Roman Defenses Against Enemy Troops
Flavius Vegetius Renatus wrote in “De Re Militari”: “If surrounded on all sides by the enemy, you must make dispositions to receive them wherever they come, and the soldiers should be cautioned beforehand to keep their arms in their hands, and to be ready in order to prevent the bad effects of a sudden attack. Men are frightened and thrown into disorder by sudden accidents and surprises of no consequence when foreseen. The ancients were very careful that the servants or followers of the army, if wounded or frightened by the noise of the action, might not disorder the troops while engaged, and also to prevent their either straggling or crowding one another too much, which might incommode their own men and give advantage to the enemy. They ranged the baggage, therefore, in the same manner as the regular troops under particular ensigns. They selected from among the servants the most proper and experienced and gave them the command of a number of servants and boys, not exceeding two hundred, and their ensigns directed them where to assemble the baggage. Proper intervals should always be kept between the baggage and the troops, that the latter may not be embarrassed for want of room in case of an attack during the march. The manner and disposition of defense must be varied according to the difference of ground. In an open country you are more liable to be attacked by horse than foot. But in a woody, mountainous or marshy situation, the danger to be apprehended is from foot. Some of the divisions being apt through negligence to move too fast, and others too slow, great care is to be taken to prevent the army from being broken or from running into too great a length, as the enemy would instantly take advantage of the neglect and penetrate without difficulty. [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) digitalattic.org]
“The tribunes, their lieutenants or the masters at arms of most experience, must therefore be posted at proper distances, in order to halt those who advance too fast and quicken such as move too slow. The men at too great a distance in the front, on the appearance of an enemy, are more disposed to fly than to join their comrades. And those too far behind, destitute of assistance, fall a sacrifice to the enemy and their own despair. The enemy, it may be concluded, will either plant ambuscades or make his attack by open force, according to the advantage of the ground. Circumspection in examining every place will be a security against concealed danger; and an ambuscade, if discovered and promptly surrounded, will return the intended mischief with interest.
“If the enemy prepare to fall upon you by open force in a mountainous country, detachments must be sent forward to occupy the highest eminences, so that on their arrival they may not dare to attack you under such a disadvantage of ground, your troops being posted so much above theIr and presenting a front ready for their reception. It is better to send men forward with hatchets and other tools in order to open ways that are narrow but safe, without regard to the labor, rather than to run any risk in the finest roads. It is necessary to be well acquainted whether the enemy usually make their attempts in the night, at break of day or in the hours of refreshment or rest; and by knowledge of their customs to guard against what we find their general practice. We must also inform ourselves whether they are strongest in infantry or cavalry; whether their cavalry is chiefly armed with lances or with bows; and whether their principal strength consists in their numbers or the excellence of their arms. All of this will enable us to take the most proper measures to distress them and for our advantage. When we have a design in view, we must consider whether it will be most advisable to begin the march by day or by night; we must calculate the distance of the places we want to reach; and take such precautions that in summer the troops may not suffer for want of water on their march, nor be obstructed in winter by impassable morasses or torrents, as these would expose the army to great danger before it could arrive at the place of its destination. As it highly concerns us to guard against these inconveniences with prudence, so it would be inexcusible not to take advantage of an enemy that fell into them through ignorance or negligence. Our spies should be constantly abroad; we should spare no pains in tampering with their men, and give all manner of encouragement to deserters. By these means we may get intelligence of their present or future designs. And we should constantly keep in readiness some detachments of cavalry and light infantry, to fall upon them when they least expect it, either on the march, or when foraging or marauding.
Roman Battle Planning and Decision-Making
Cristian Violatti of Listverse wrote: “During the times of the Roman Republic, only the Senate, considered the governmental entity that embodied the will of Roman citizens, was entitled to declare war. As Rome expanded and the power of its generals grew larger, some wars were declared by the Roman generals without senatorial approval. An example of this was the war against Mithridates of Pontus, which was declared in 89 B.C. by the consul and general Manius Aquillius without any involvement from the Senate. This was illegal in theory, but in practice, there was little the Senate could do. Some generals were just too powerful. When Rome became an empire, the decision of going to war became the emperor’s responsibility alone. [Source: Cristian Violatti, Listverse, September 4, 2016 ]
Flavius Vegetius Renatus wrote in “De Re Militari”: “A battle is commonly decided in two or three hours, after which no further hopes are left for the worsted army. Every plan, therefore, is to be considered, every expedient tried and every method taken before matters are brought to this last extremity. Good officers decline general engagements where the danger is common, and prefer the employment of stratagem and finesse to destroy the enemy as much as possible in detail and intimidate them without exposing our own forces.
“I shall insert some necessary instructions on this head collected from the ancients. It is the duty and interest of the general frequently to assemble the most prudent and experienced officers of the different corps of. the army and consult with them on the state both of his own and the enemy's forces. All overconfidence, as most pernicious in its consequences, must be banished from the deliberations. He must examine which has the superiority in numbers, whether his or the adversary's troops are best armed, which are in the best condition, best disciplined and most resolute in emergencies. The state of the cavalry of both armies must be inquired into, but more especially that of the infantry, for the main strength of an army consists of the latter. With respect to the cavalry, he must endeavor to find out in which are the greatest numbers of archers or of troopers armed with lances, which has the most cuirassiers and which the best horses. Lastly he must consider the field of battle and to judge whether the ground is more advantageous for him or his enemy. If strongest in cavalry, we should prefer plains and open ground; if superior in infantry, we should choose a situation full of enclosures, ditches, morasses and woods, and sometimes mountainous. Plenty or scarcity in either army are considerations of no small importance, for famine, according to the common proverb, is an internal enemy that makes more havoc than the sword. But the most material article is to determine whether it is most proper to temporize or to bring the affair to a speedy decision by action. The enemy sometimes expect an expedition will soon be over; and if it is protracted to any length, his troops are either consumed by want,. induced to return home by the desire of seeing their families or, having done nothing considerable in the field, disperse themselves from despair of success. Thus numbers, tired out with fatigue and disgusted with the service, desert, others betray them and many surrender themselves. Fidelity is seldom found in troops disheartened by misfortunes. And in such case an army which was numerous on taking the field insensibly dwindles away to nothing.
“It is essential to know the character of the enemy and of their principal officers-whether they be. rash or cautious, enterprising or timid, whether they fight on principle or from chance and whether the nations they have been engaged with were brave or cowardly. We must know how far to depend upon the fidelity and strength of auxiliaries, how the enemy's troops and our own are affected and which appear most confident of success, a consideration of great effect in raising or depressing the courage of an army. A harangue from the general, especially if he seems under no apprehension himself, may reanimate the soldiers if dejected. Their spirits revive if any considerable advantage is gained either by stratagem or otherwise, if the fortune of the enemy begins to change or if you can contrive to beat some of their weak or poorly-armed detachments.
“But you must by no means venture to lead an irresolute or diffident army to a general engagement. The difference is great whether your troops are raw or veterans, whether inured to war by recent service or for some years unemployed. For soldiers unused to fighting for a length of time must be considered in the same light as recruits. As soon as the legions, auxiliaries and cavalry are assembled from their several quarters, it is the duty of a good general to have every corps instructed separately in every part of the drill by tribunes of known capacity chosen for that purpose. He should afterwards form them into one body and train them in all the maneuvers of the line as for a general action. He must frequently drill them himself to try their skill and strength, and to see whether they perform their evolutions with proper regularity and are sufficiently attentive to the sound of the trumpets, the motions of the colors and to his own orders and signals. If deficient in any of these particulars, they must be instructed and exercised till perfect.
“But though thoroughly disciplined and complete in their field exercises, in the use of the bow and javelin, and in the evolutions of the line, it is not advisable to lead them rashly or immediately to battle. A favorable opportunity must be watched for, and they must first be prepared by frequent skirmishes and slight encounters. Thus a vigilant and prudent general will carefully weigh in his council the state of his own forces and of those of the enemy, just as a civil magistrate judging between two contending parties. If he finds himself in many respects superior to his adversary, he must by no means defer bringing on an engagement. But if he knows himself inferior, he must avoid general actions and endeavor to succeed by surprises, ambuscades and stratagems. These, when skillfully managed by good generals, have often given them the victory over enemies superior both in numbers and strength.
Polybius: Roman Versus Macedonian-Greek Military Tactics
Polybius (ca. 200-118 B.C.) was a Greek historian of the Hellenistic period noted for his work “The Histories,” which covered the period of 264–146 B.C., when the Roman Republic became dominant power in the ancient Mediterranean world. In a section that addressed “The Roman Maniple vs. The Macedonian Phalanx,” Polybius wrote in Book XVIII, Chapters 28-32 of “The Histories”: “In former times the Macedonian tactics proved themselves by experience capable of conquering those of Asia and Greece; while the Roman tactics sufficed to conquer the nations of Africa and all those of Western Europe; and since in our own day there have been numerous opportunities of comparing the men as well as their tactics, it will be, I think, a useful and worthy task to investigate their differences, and discover why it is that the Romans conquer and carry off the palm from their enemies in the operations of war: that we may not put it all down to Fortune, and congratulate them on their good luck, as the thoughtless of mankind do; but, from a knowledge of the true causes, may give their leaders the tribute of praise and admiration which they deserve. [Source: Polybius,”The Histories of Polybius”, 2 Vols., translated by Evelyn S. Shuckburgh (London: Macmillan, 1889), pp. 226-230]
“Now as to the battles which the Romans fought with Hannibal and the defeats which they sustained in them, I need say no more. It was not owing to their arms or their tactics, but to the skill and genius of Hannibal that they met with those defeats: and that I made quite clear in my account of the battles themselves. And my contention is supported by two facts. First, by the conclusion of the war: for as soon as the Romans got a general of ability comparable with that of Hannibal, victory was not long in following their banners. Secondly, Hannibal himself, being dissatisfied with the original arms of his men, and having immediately after his first victory furnished his troops with the arms of the Romans, continued to employ them thenceforth to the end. Pyrrhus, again, availed himself not only of the arms, but also of the troops of Italy, placing a maniple of Italians and a company of his own phalanx alternately, in his battles against the Romans. Yet even this did not enable him to win; the battles were somehow or another always indecisive. It was necessary to speak first on these points, to anticipate any instances which might seem to make against my theory. I will now return to my comparison.
Greek-Macedonian Phalanx Verus Roman Military Formations
Polybius wrote in Book XVIII, Chapters 28-32 of “The Histories”: “Many considerations may easily convince us that, if only the phalanx has its proper formation and strength, nothing can resist it face to face or withstand its charge. For as a man in close order of battle occupies a space of three feet; and as the length of the sarissae are sixteen cubits according to the original design, which has been reduced in practice to fourteen; and as of these fourteen four must be deducted, to allow for the weight in front; it follows clearly that each hoplite will have ten cubits of his sarissa projecting beyond his body, when he lowers it with both hands, as he advances against the enemy: hence, too, though the men of the second, third, and fourth rank will have their sarissae projecting farther beyond the front rank than the men of the fifth, yet even these last will have two cubits of their sarissae beyond the front rank; if only the phalanx is properly formed and the men close up properly both flank and rear, like the description in Homer: ‘So buckler pressed on buckler; helm on helm; And man on man; and waving horse-hair plumes In polished head-piece mingled, as they swayed In order: in such serried rank they stood. [Iliad, 13.131] [Source: Polybius,”The Histories of Polybius”, 2 Vols., translated by Evelyn S. Shuckburgh (London: Macmillan, 1889), pp. 226-230]
“And if my description is true and exact, it is clear that in front of each man of the front rank there will be five sarissae projecting to distances varying by a descending scale of two cubits. With this point in our minds, it will not be difficult to imagine what the appearance and strength of the whole phalanx is likely to be, when, with lowered sarissae, it advances to the charge sixteen deep. Of these sixteen ranks, all above the fifth are unable to reach with their sarissae far enough to take actual part in the fighting. They, therefore, do not lower them, but hold them with the points inclined upwards over the shoulders of the ranks in front of them, to shield the heads of the whole phalanx; for the sarissae are so closely serried, that they repel missiles which have carried over the front ranks and might fall upon the heads of those in the rear. These rear ranks, however, during an advance, press forward those in front by the weight of their bodies; and thus make the charge very forcible, and at the same time render it impossible for the front ranks to face about. “Such is the arrangement, general and detailed of the phalanx.
It remains now to compare with it the peculiarities and distinctive features of the Roman arms and tactics. Now, a Roman soldier in full armor also requires a space of three square feet. But as their method of fighting admits of individual motion for each man — because he defends his body with a shield, which he moves about to any point from which a blow is coming, and because he uses his sword both for cutting and stabbing — it is evident that each man must have a clear space, and an interval of at least three feet both on flank and rear if he is to do his duty with any effect. The result of this will be that each Roman soldier will face two of the front rank of a phalanx, so that he has to encounter and fight against ten spears, which one man cannot find time even to cut away, when once the two lines are engaged, nor force his way through easily — seeing that the Roman front ranks are not supported by the rear ranks, either by way of adding weight to their charge, or vigor to the use of their swords. Therefore, it may readily be understood that, as I said before, it is impossible to confront a charge of the phalanx, so long as it retains its proper formation and strength.”
Superiority of Roman Tactics
Polybius wrote in Book XVIII, Chapters 28-32 of “The Histories”: “Why is it then that the Romans conquer? And what is it that brings disaster on those who employ the phalanx? Why, just because war is full of uncertainties both as to time and place; whereas there is but one time and one kind of ground in which a phalanx can fully work. If, then, there were anything to compel the enemy to accommodate himself to the time and place of the phalanx, when about to fight a general engagement, it would be but natural to expect that those who employed the phalanx would always carry off the victory. But if the enemy finds it possible, and even easy, to avoid its attack, what becomes of its formidable character? Again, no one denies that for its employment it is indispensable to have a country flat, bare, and without such impediments as ditches, cavities, depressions, steep banks, or beds of rivers: for all such obstacles are sufficient to hinder and dislocate this particular formation. And that it is, I may say, impossible, or at any rate exceedingly rare to find a piece of country of twenty stades, or sometimes of even greater extent, without any such obstacles, every one will also admit. [Source: Polybius,”The Histories of Polybius”, 2 Vols., translated by Evelyn S. Shuckburgh (London: Macmillan, 1889), pp. 226-230]
“However, let us suppose that such a district has been found. If the enemy decline to come down into it, but traverse the country sacking the towns and territories of the allies, what use will the phalanx be? For if it remains on the ground suited to itself, it will not only fail to benefit its friends, but will be incapable even of preserving itself; for the carriage of provisions will be easily stopped by the enemy, seeing that they are in undisputed possession of the country: while if it quits its proper ground, from the wish to strike a blow, it will be an easy prey to the enemy. Nay, if a general does descend into the plain, and yet does not risk his whole army upon one charge of the phalanx or upon one chance, but maneuvers for a time to avoid coming to close quarters in the engagement, it is easy to learn what will be the result from what the Romans are now actually doing.
“For no speculation is any longer required to test the accuracy of what I am now saying: that can be done by referring to accomplished facts. The Romans do not, then, attempt to extend their front to equal that of a phalanx, and then charge directly upon it with their whole force: but some of their divisions are kept in reserve, while others join battle with the enemy at close quarters. Now, whether the phalanx in its charge drives its opponents from their ground, or is itself driven back, in either case its peculiar order is dislocated; for whether in following the retiring, or flying from the advancing enemy, they quit the rest of their forces: and when this takes place, the enemy's reserves can occupy the space thus left, and the ground which the phalanx had just before been holding, and so no longer charge them face to face, but fall upon them on their flank and rear. If, then, it is easy to take precautions against the opportunities and peculiar advantages of the phalanx, but impossible to do so in the case of its disadvantages, must it not follow that in practice the difference between these two systems is enormous? Of course, those generals who employ the phalanx must march over ground of every description, must pitch camps, occupy points of advantage, besiege, and be besieged, and meet with unexpected appearances of the enemy: for all these are part and parcel of war, and have an important and sometimes decisive influence on the ultimate victory. And in all these cases the Macedonian phalanx is difficult, and sometimes impossible, to handle, because the men cannot act either in squads or separately.
“The Roman order on the other hand is flexible: for every Roman, once armed and on the field, is equally well-equipped for every place, time, or appearance of the enemy. He is, moreover, quite ready and needs to make no change, whether he is required to fight in the main body, or in a detachment, or in a single maniple, or even by himself. Therefore, as the individual members of the Roman force are so much more serviceable, their plans are also much more often attended by success than those of others.”
Preventing Mutinies and Managing Raw and Undisciplined Troops
Cristian Violatti of Listverse wrote: “Mutiny of the troops was always a potential issue for Roman generals, and there were many policies in place to discourage this type of behavior. Punishment by decimation (decimatio) was arguably the most feared and effective. It involved the beating or stoning to death of every 10th man within the army unit where mutiny took place. The victims were chosen by lot by their own colleagues. Whenever a group within the army was planning a mutiny, the prospect of decimation made them think twice and they were likely to be reported by their own colleagues. [Source: Cristian Violatti, Listverse, September 4, 2016 ]
“The Romans knew that decimation, although effective, was also unjust because many of the actual victims might not have had anything to do with the mutiny. From the standpoint of the Romans, the unfairness of decimation was a necessary evil. Tacitus (Annals 14.44) wrote, “Setting an example on a large scale always involves a degree of injustice when individuals suffer to ensure the public good.” (McKeown 2010: 40-41)
Flavius Vegetius Renatus wrote in “De Re Militari”: “It is indispensably necessary for those engaged in war not only to instruct them in the means of preserving their own lives, but how to gain the victory over their enemies.A commander-in-chief therefore, whose power and dignity are so great and to whose fidelity and bravery the fortunes of his countrymen, the defense of their cities, the lives of the soldiers, and the glory of the state, are entrusted, should not only consult the good of the army in general, but extend his care to every private soldier in it. For when any misfortunes happen to those under his command, they are considered as public losses and imputed entirely to his misconduct. If therefore he finds his army composed of raw troops or if they have long been unaccustomed to fighting, he must carefully study the strength, the spirit, the manners of each particular legion, and of each body of auxiliaries, cavalry and infantry. He must know, if possible, the name and capacity of every count, tribune, subaltern and soldier. He must assume the most respectable authority and maintain it by severity. He must punish all military crimes with the greatest rigor of the laws. He must have the character of being inexorable towards offenders and endeavor to give public examples thereof in different places and on different occasions.

“Having once firmly established these regulations, he must watch the opportunity when the enemy, dispersed in search of plunder, think themselves in security, and attack them with detachments of tried cavalry or infantry, intermingled with young soldiers, or such as are under the military age. The veterans will acquire fresh experience and the others will be inspired with courage by the advantages such opportunities will give him. He should form ambuscades with the greatest secrecy to surprise the enemy at the passages of rivers, in the rugged passes of mountains, in defiles in woods and when embarrassed by morasses or difficult roads. He should regulate his march so as to fall upon them while taking their refreshments or sleeping, or at a time when they suspect no dangers and are dispersed, unarmed and their horses unsaddled. He should continue these kinds of encounters till his soldiers have imbibed a proper confidence in themselves. For troops that have never been in action or have not for some time been used to such spectacles, are greatly shocked at the sight of the wounded and dying; and the impressions of fear they receive dispose them rather to fly than fight.
“If the enemy makes excursions or expeditions, the general should attack him after the fatigue of a long march, fall upon him unexpectedly, or harass his rear. He should detach parties to endeavor to carry off by surprise any quarters established at a distance from the hostile army for the convenience of forage or provisions. F or such measures should be pursued at first as can produce no very bad effects if they should happen to miscarry, but would be of great advantage if attended with success. A prudent general will also try to sow dissention among his adversaries, for no nation, though ever so weak in itself can be completely ruined by its enemies unless its fall be facilitated by its own distraction. In civil dissensions men are so intent on the destruction of their private enemies that they are entirely regardless of the public safety.
“One maxim must be remembered throughout this work: that no one should ever despair of effecting what has been already performed. It may be said that our troops for many years past have not even fortified their permanent camps with ditches, ramparts or palisades. The answer is plain. If those precautions had been taken, our armies would never have suffered by surprises of the enemy both by day and night. The Persians, after the example of the old Romans, surround their camps with ditches and, as the ground in their country is generally sandy, they always carry with them empty bags to fill with the sand taken out of the trenches and raise a parapet by piling them one on the other. All the barbarous nations range their carriages round them in a circle, a method which bears some resemblance to a fortified camp. They thus pass their nights secure from surprise.
“Are we afraid of not being able to learn from others what they before have learned from us? At present all this is to be found in books only, although formerly constantly practiced. Inquiries are now no longer made about customs that have been so long neglected, because in the midst of peace, war is looked upon as an object too distant to merit consideration. But former instances will convince us that the reestablishment of ancient discipline is by no means impossible, although now so totally lost.
“In former ages the art of war, often neglected and forgotten, was as often recovered from books and reestablished by the authority and attention of our generals. Our armies in Spain, when Scipio Africanus took the command, were in bad order and had often been beaten under preceding generals. He soon reformed them by severe discipline and obliged them to undergo the greatest fatigue in the different military works, reproaching them that since they would not wet their hands with the blood of their enemies, they should soil them with the mud of the trenches. In short, with these very troops he afterwards took the city of Numantia and burned it to the ground with such destruction of its inhabitants that not one escaped. In Africa an army, which under the command of Albinus had been forced to pass under the yoke, was by Metellus brought into such order and discipline, by forming it on the ancient model, that they afterwards vanquished those very enemies who had subjected them to that ignominious treatment. The Cimbri defeated the legions of Caepio, Manilus and Silanus in Gaul, but Marius collected their shattered remnants and disciplined them so effectually that he destroyed an innumerable multitude of the Cimbri, Teutones and Ambrones in one general engagement. Nevertheless it is easier to form young soldiers and inspire them with proper notions of honor than to reanimate troops who have been once disheartened.”
Roman Preparations for Battle and Gaging Morale
Flavius Vegetius Renatus wrote in “De Re Militari” (“Military Institutions of the Romans”): “Having explained the less considerable branches of the art of war, the order of military affairs naturally leads us to the general engagement. This is a conjuncture full of uncertainty and fatal to kingdoms and nations, for in the decision of a pitched battle consists the fulness of victory. This eventuality above all others requires the exertion of all the abilities of a general, as his good conduct on such an occasion gains him greater glory, or his dangers expose him to greater danger and disgrace. This is the moment in which his talents, skill and experience show themselves in their fullest extent. [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.

“Formerly to enable the soldiers to charge with greater vigor, it was customary to order them a moderate refreshment of food before an engagement, so that their strength might be the better supported during a long conflict. When the army is to march out of a camp or city in the presence of their enemies drawn up and ready for action, great precaution must be observed lest they should be attacked as they defile from the gates and be cut to pieces in detail. Proper measures must therefore be taken so that the whole army may be clear of the gates and form in order of battle before the enemy's approach. If they are ready before you can have quitted the place, your design of marching out must either be deferred till another opportunity or at least dissembled, so that when they begin to insult you on the supposition that you dare not appear, or think of nothing but plundering or returning and no longer keep their ranks, you may sally out and fall upon them while in confusion and surprise. Troops must never be engaged in a general action immediately after a long march, when the men are fatigued and the horses tired. The strength required for action is spent in the toil of the march. What can a soldier do who charges when out of breath? The ancients carefully avoided this inconvenience, but in later times some of our Roman generals, to say nothing more, have lost their armies by unskillfully neglecting this precaution. Two armies, one tired and spent, the other fresh and in full vigor, are by no means an equal match.
“It is necessary to know the sentiments of the soldiers on the day of an engagement. Their confidence or apprehensions are easily discovered by their looks, their words, their actions and their motions. No great dependence is to be placed on the eagerness of young soldiers for action, for fighting has something agreeable in the idea to those who are strangers to it. On the other hand, it would be wrong to hazard an engagement, if the old experienced soldiers testify to a disinclination to fight. A general, however, may encourage and animate his troops by proper exhortations and harangues, especially if by his account of the approaching action he can persuade them into the belief of an easy victory. With this view, he should lay before them the cowardice or unskillfulness of their enemies and remind them of any former advantages they may have gained over them. He should employ every argument capable of exciting rage, hatred and indignation against the adversaries in the minds of his soldiers.
“It is natural for men in general to be affected with some sensations of fear at the beginning of an engagement, but there are without doubt some of a more timorous disposition who are disordered by the very sight of the enemy. To diminish these apprehensions before you venture on action, draw up your army frequently in order of battle in some safe situation, so that your men may be accustomed to the sight and appearance of the enemy. When opportunity offers, they should be sent to fall upon them and endeavor to put them to flight or kill some of their men. Thus they will become acquainted with their customs, arms and horses. And the objects with which we are once familiarized are no longer capable of inspiring us with terror.”
Roman Ideas on Choosing Battlefield Sites and Organizing Troops
Flavius Vegetius Renatus wrote in “De Re Militari”: “Choice of the Field of Battle: Good generals are acutely aware that victory depends much on the nature of the field of battle. When you intend therefore to engage, endeavor to draw the chief advantage from your situation. The highest ground is reckoned the best. Weapons thrown from a height strike with greater force; and the party above their antagonists can repulse and bear them down with greater impetuosity, while they who struggle with the ascent have both the ground and the enemy to contend with. There is, however, this difference with regard to place: if you depend on your foot against the enemy's horse, you must choose a rough, unequal and mountainous situation. But if, on the contrary, you expect your cavalry to act with advantage against the enemy's infantry, your ground must indeed be higher, but plain and open, without any obstructions of woods or morasses. [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) digitalattic.org]
“Order of Battle: In drawing up an army in order of battle, three things are to be considered: the sun, the dust and the wind. The sun in your face dazzles the sight: if the wind is against you, it turns aside and blunts the force of your weapons, while it assists those of your adversary; and the dust driving in your front fills the eyes of your men and blinds them. Even the most unskillful endeavor to avoid these inconveniences in the moment of making their dispositions; but a prudent general should extend his views beyond the present; he should talke such measures as not to be incommoded in the course of the day by different aspects of the sun or by contrary winds which often rise at a certain hour and might be detrimental during action. Our troops should be so disposed as to have these inconveniences behind them, while they are directly in the enemy's front.
“Proper Distances and Intervals: Having explained the general disposition of the lines, we now come to the distances and dimensions. One thousand paces contain a single rank of one thousand six hundred and fifty-six foot soldiers, each man being allowed three feet. Six ranks drawn up on the same extent of ground will require nine thousand nine hundred and ninety-six men. To form only three ranks of the same number will take up two thousand paces, but it is much better to increase the number of ranks than to make your front too extensive. We have before observed the distance between each rank should be six feet, one foot of which is taken up by the men. Thus if you form a body of ten thousand men into six ranks they will occupy thirty-six feet. in depth and a thousand paces in front. By this calculation it is easy to compute the extent of ground required for twenty or thirty thousand men to form upon. Nor can a general be mistaken when thus he knows the proportion of ground for any fixed number of men.
“But if the field of battle is not spacious enough or your troops are very numerous, you may form them into nine ranks or even more, for it is more advantageous to engage in close order that to extend your line too much. An army that takes up too much ground in front and too little in depth, is quickly penetrated by the enemy's first onset. After this there is no remedy. As to the post of the different corps in the right or left wing or in the center, it is the general rule to draw them up according to their respective ranks or to distribute them as circumstances or the dispositions of the enemy may require.”
Roman Views on Troop Placement
Flavius Vegetius Renatus wrote in “De Re Militari”: “The line of infantry being formed, the cavalry are drawn up in the wings. The heavy horse, that is, the cuirassiers and troopers armed with lances, should join the infantry. The light cavalry, consisting of the archers and those who have no cuirasses, should be placed at a greater distance. The best and heaviest horse are to cover the flanks of the foot, and the light horse are posted as abovementioned to surround and disorder the enemy's wings. A general should know what part of his own cavalry is most proper to oppose any particular squadrons or troops of the enemy. For from some causes not to be accounted for some particular corps fight better against others, and those who have defeated superior enemies are often overcome by an inferior force. [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) digitalattic.org]
“If your cavalry is not equal to the enemy's it is proper, after the ancient custom, to intermingle it with light infantry armed with small shields and trained to this kind of service. By observing this method, even though the flower of the enemy's cavalry should attack you, they will never be able to cope with this mixed disposition. This was the only resource of the old generals to supply the defects of their cavalry, and they intermingled the men, used to running and armed for this purpose with light shields, swords and darts, among the horse, placing one of them between two troopers.
“Reserves: The method of having bodies of reserves in rear of the army, composed of choice infantry and cavalry, commanded by the supernumerary lieutenant generals, counts and tribunes, is very judicious and of great consequence towards the gaining of a battle. Some should be posted in rear of the wings and some near the center, to be ready to fly immediately to the assistance of any part of the line which is hard pressed, to prevent its being pierced, to supply the vacancies made therein during the action and thereby to keep up the courage of their fellow soldiers and check the impetuosity of the enemy. This was an invention of the Lacedaemonians [Spartans] , in which they were imitated by the Carthaginians. The Romans have since observed it, and indeed no better disposition can be found.
“The line is solely designed to repulse, or if possible, break the enemy. If it is necessary to form the wedge or the pincers, it must be done by the supernumerary troops stationed in the rear for that purpose. If the saw is to be formed, it must also be done from the reserves, for if once you begin to draw off men from the line you throw all into confusion. If any flying platoon of the enemy should fall upon your wing or any other part of your army, and you have no supernumerary troops to oppose it or if you pretend to detach either horse or foot from your line for that service by endeavoring to protect one part, you will expose the other to greater danger. In armies not very numerous, it is much better to contract the front, and to have strong reserves. In short, you must have a reserve of good and well-armed infantry near the center to form the wedge and thereby pierce the enemy's line; and also bodies of cavalry armed with lances and cuirasses, with light infantry, near the wings, to surround the flanks of the enemy.
Roman Battle Leadership
Flavius Vegetius Renatus wrote in “De Re Militari”: “ Post of the General and of the Second and Third in Command: The post of the commander-in-chief is generally on the right between the cavalry and infantry. For from this place he can best direct the motions of the whole army and move elements with the greatest ease wherever he finds it necessary. It is also the most convenient spot to give his orders to both horse and foot and to animate them equally by his presence. It is his duty to surround the enemy's left wing opposed to him with his reserve of horse and light infantry, and attack it in the flank and rear. [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) digitalattic.org]
The second in command is posted in the center of the infantry to encourage and support them. A reserve of good and well-armed infantry is near him and under his orders. With this reserve he either forms the wedge to pierce the enemy's line or, if they form the wedge first, prepares the pincers for its reception. The post of the third in command is on the left. He should be a careful and intrepid officer, this part of the army being difficult to manage and defective, as it were, from its situation in the line. He should therefore have a reserve of good cavalry and active infantry to enable him always to extend his left in such a manner as to prevent its being surrounded.
“The war shout should not be begun till both armies have joined, for it is a mark of ignorance or cowardice to give it at a distance. The effect is much greater on the enemy when they find themselves struck at the same instant with the horror of the noise and the points of the weapons. You must always endeavor to get the start of your enemy in drawing up in order of battle, as you will then have it in your power to make your proper dispositions without obstruction. This will increase the courage of your own troops and intimidate your adversaries. For a superiority of courage seems to be implied on the side of an army that offers battle, whereas troops begin to be fearful who see their enemies ready to attack them. You will also secure another great advantage, that of marching up in order and falling upon them while forming and still in confusion. For part of the victory consists in throwing the enemy into disorder before you engage them.
Roman Battle Maneuvers
Flavius Vegetius Renatus wrote in “De Re Militari”: “An able general never loses a favorable opportunity of surprising the enemy either when tired on the march, divided in the passage of a river, embarrassed in morasses, struggling with the declivities of mountains, when dispersed over the country they think themselves in security or are sleeping in their quarters. In all these cases the adversaries are surprised and destroyed before they have time to put themselves on their guard. But if they are too cautious to give you an opportunity of surprising or ensnaring them, you are then obliged to engage openly and on equal terms. This at present is foreign to the subject. However military skill is no less necessary in general actions than in carrying on war by subtlety and stratagem. [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) digitalattic.org]
“Your first care is to secure your left wing from being surrounded by the enemy's numbers or attacked in flank or rear by flying platoons, a misfortune that often happens. Nor is your right to be neglected, though less frequently in danger. There is only one remedy for this: to wheel back your wing and throw it into a circular position. By this evolution your soldiers meet the enemy on the quarter attacked and defend the rear of their comrades. But your best men should be posted on the angles of the flanks, since it is against them the enemy make their principal efforts.
“There is also a method of resisting the wedge when formed by the enemy. The wedge is a disposition of a body of infantry widening gradually towards the base and terminating in a point towards the front. It pierces the enemy's line by a multitude of darts directed to one particular place. The soldiers call it the swine's head. To oppose this disposition, they make use af another called the pincers, resembling the letter V, composed of a body of men in close order. It receives the wedge, inclosing it on both sides, and thereby prevents it from penetrating the line.
“The saw is another disposition formed of resolute soldiers drawn up in a straight line advanced into the front against the enemy, to repair any disorder. The platoon is a body of men separated from the line, to hover on every side and attack the enemy wherever they find opportunity. And against this is to be detached a stronger and more numerous platoon.
“Above all, a general must never attempt to alter his dispositions or break his order of battle during the time of action, for such an alteration would immediately Occasion disorder and confusion which the enemy would not fail to improve to their advantage.
Roman Battle Formations
Flavius Vegetius Renatus wrote in “De Re Militari”: “An army may be drawn up for a general engagement in seven different formations. The first formation is an oblong square of a large front, of common use both in ancient and modern times, although not thought the best by various judges of the service, because an even and level plain of an extent sufficient to contain its front cannot always be found, and if there should be any irregularity or hollow in the line, it is often pierced in that part. Besides, an enemy superior in number may surround either your right or left wing, the consequence of which will be dangerous, unless you have a reserve ready to advance and sustain his attack. A general should make use of this disposition only when his forces are better and more numerous than the enemy's, it being thereby in his power to attack both the flanks and surround them on every side. [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) digitalattic.org]
“The second and best disposition is the oblique. For although your army consists of few troops, yet good and advantageously posted, it will greatly contribute to your obtaining the victory, notwithstanding the numbers and bravery of the enemy. It is as follows: as the armies are marching up to the attack, your left wing must be kept back at such a distance from the enemy's right as to be out of reach of their darts and arrows. Your right wing must advance obliquely upon the enemy's left, and begin the engagement. And you must endeavor with your best cavalry and infantry to surround the wing with which you are engaged, make it give way and fall upon the enemy in the rear. If they once give ground and the attack is properly seconded, you will undoubtedly gain the victory, while your left wing, which continued at a distance, will remain untouched. An army drawn up in this manner bears some resemblance to the letter A or a mason's level. If the enemy should be beforehand with you in this evolution, recourse must be had to the supernumerary horse and foot posted as a reserve in the rear, as I mentioned before. They must be ordered to support your left wing. This will enable you to make a vigorous resistance against the artifice of the enemy.
“The third formation is like the second, but not so good, as it obliges you to begin the attack with your left wing on the enemy's right. The efforts of soldiers on the left are weak and imperfect from their exposed and defective situation in the line. I will explain this formation more clearly. Although your left wing should be much better than your right, yet it must be reinforced with some of the best horse and foot and ordered to commence the acnon with the enemy's right in order to disorder and surround it as expeditiously as possible. And the other part of your army, composed of the worst troops, should remain at such a distance from the enemy's left as not to be annoyed by their darts or in danger of being attacked sword in hand. In this oblique formation care must be taken to prevent the line being penetrated by the wedges of the enemy, and it is to be employed only when the enemy's right wing is weak and your greatest strength is on your left.
“The fourth formation is this: as your army is marching to the attack in order of battle and you come within four or five hundred paces of the enemy, both your wings must be ordered unexpectedly to quicken their pace and advance with celerity upon them. When they find themselves attacked on both wings at the same time, the sudden surprise may so disconcert them as to give you an easy victory. But although this method, if your troops are very resolute and expert, may ruin the enemy at once, yet it is hazardous. The general who attempts it is obliged to abandon and expose his center and to divide his army into three parts. If the enemy are not routed at the first charge, they have a fair opportunity of attacking the wings which are separated from each other and the center which is destitute of assistance.
“The fifth formation resembles the fourth but with this addition: the light infantry and the archers are formed before the center to cover it from the attempts of the enemy. With this precaution the general may safely follow the above mentioned method and attack the enemy's left wing with his right, and their right with his left. If he puts them to flight, he gains an immediate victory, and if he fails of success his center is in no danger, being protected by the light infantry and archers.
“The sixth formation is very good and almost like the second. It is used when the general cannot depend either on the number or courage of his troops. If made with judgment, notwithstanding his inferiority, he has often a good chance for victory. As your line approaches the enemy, advance your right wing against their left and begin the attack with your best cavalry and infantry. At the same time keep the rest of the army at a great distance from the enemy's right, extended in a direct line like a javelin. Thus if you can surround their left and attack it in flank and rear, you must inevitably defeat them. It is impossible for the enemy to draw off reinforcements from their right or from their center to sustain their left in this emergency, since the remaining part of your army is extended and at a great distance from them in the form of the letter L. It is a formation often used in an action on a march.
“The seventh formation owes its advantages to the nature of the ground and will enable you to oppose an enemy with an army inferior both in numbers and goodness, provided one of your flanks can be covered either with an eminence, the sea, a river, a lake, a city, a morass or broken ground inaccessible to the enemy. The rest of the army must be formed, as usual, in a straight line and the unsecured flank must be protected by your light troops and all your cavalry. Sufficiently defended on one side by the nature of the ground and on the other by a double support of cavalry, you may then safely venture on action.
“One excellent and general rule must be observed. If you intend to engage with your right wing only, it must be composed of your best troops. And the same method must be taken with respect to the left. Or if you intend to penetrate the enemy's line, the wedges which you form for that purpose before your center, must consist of the best disciplined soldiers. Victory in general is gained by a small number of men. Therefore the wisdom of a general appears in nothing more than in such choice of disposition of his men as is most consonant with reason and service.
Roman Ideas About Retreats
Flavius Vegetius Renatus wrote in “De Re Militari”: “ Flight of an Enemy Should Not Be Prevented, but Facilitated: Generals unskilled in war think a victory incomplete unless the enemy are so straightened in their ground or so entirely surrounded by numbers as to have no possibility of escape. But in such situation, where no hopes remain, fear itself will arm an enemy and despair inspires courage. When men find they must inevitably perish, they willingly resolve to die with their comrades and with their arms in their hands. The maxim of Scipio, that a golden bridge should be made for a flying enemy, has much been commended. For when they have free room to escape they think of nothing but how to save themselves by flight, and the confusion becoming general, great numbers are cut to pieces. The pursuers can be in no danger when the vanquished have thrown away their arms for greater haste. In this case the greater the number of the flying army, the greater the slaughter. Numbers are of no signification where troops once thrown into consternation are equally terrified at the sight of the enemy as at their weapons. But on the contrary, men when shut up, although weak and few in number, become a match for the enemy from this very reflection, that they have no resource but in despair. “"The conquer'd's safety is, to hope for none."” [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) digitalattic.org]
Manner of Conducting a Retreat: Having gone through the various particulars relative to general actions, it remains at present to explain the manner of retreating in presence of the enemy. This is an operation, which, in the judgment of men of greatest skill and experience, is attended with the utmost hazard. A general certainly discourages his own troops and animates his enemies by retiring out of the field without fighting. Yet as this must sometimes necessarily happen, it will be proper to consider how to perform it with safety.
“In the first place your men must not imagine that you retire to decline an action, but believe your retreat an artifice to draw the enemy into an ambuscade or more advantageous position where you may easier defeat them in case they follow you. For troops who perceive their general despairs of success are prone to flight. You must be cautious lest the enemy should discover your retreat and immediately fall upon you. To avoid this danger the cavalry are generally posted in the front of the infantry to conceal their motions and retreat from the enemy. The first divisions are drawn off first, the others following in their turns. The last maintain their ground till the rest have marched off, and then file off themselves and join them in a leisurely and regular succession. Some generals have judged it best to make their retreat in the night after reconnoitering their routes, and thus gain so much ground that the enemy, not discovering their departure till daybreak, were not able to come up with them. The light infantry was also sent forward to possess the eminences under which the army might instantly retire with safety; and the enemy, in case they pursued, be exposed to the light infantry, masters of the heights, seconded by the cavalry.
“A rash and inconsiderate pursuit exposes an army to the greatest danger possible, that of falling into ambuscades and the hands of troops ready for their reception. For as the temerity of an army is increased and their caution lessened by the pursuit of a flying enemy, this is the most favorable opportunity for such snares. The greater the security, the greater the danger. Troops, when unprepared, at their meals, fatigued after a march, when their horses are feeding, and in short, when they believe themselves most secure, are generally most liable to a surprise. All risks of this sort are to be carefully avoided and all opportunities taken of distressing the enemy by such methods. Neither numbers nor courage avail in misfortunes of this nature.
“A general who has been defeated in a pitched battle, although skill and conduct have the greatest share in the decision, may in his defense throw the blame on fortune. But if he has suffered himself to be surprised or drawn into the snares of his enemy, he has no excuse for his fault, because he might have avoided such a misfortune by taking proper precautions and employing spies on whose intelligence he could depend.
“When the enemy pursue a retreating foe, the following snare is usually laid. A small body of cavalry is ordered to pursue them on the direct road. At the same time a strong detachment is secretly sent another way to conceal itself on their route. When the cavalry have overtaken the enemy, they make some feint attacks and retire. The enemy, imagining the danger past, and that they have escaped the snare, neglect their order and march without regularity. Then the detachment sent to intercept them, seizing the opportunity, falls upon them unexpectedly and destroys them with ease.
“Many generals when obliged to retreat through woods send forward parties to seize the defiles and difficult passes, to avoid ambuscades and block the roads with barricades of felled trees to secure themselves from being pursued and attacked in the rear. In short both sides have equal opportunities of surprising or laying ambuscades on th1e march. The army which retreats leaves troops behind for that purpose posted in convenient valleys or mountains covered with woods, and if the enemy falls into the snare, it returns immediately to their assistance. The army that pursues detaches different parties of light troops to march ahead through by-roads and intercepts the enemy, who are thus surrounded and attacked at once in front and rear. The flying army may return and fall on the enemy while asleep in the night. And the pursuing army may, even though the distance is great, surprise the adversary by forced marches. The former endeavor may be at the crossing of a river in order to destroy such part of the enemy's army as has already crossed. The pursuers hasten their march to fall upon those bodies of the enemy that have not yet crossed.
Resources in Case of Defeat
Flavius Vegetius Renatus wrote in “De Re Militari”: “If while one part of your army is victorious the other should be defeated, you are by no means to despair, since even in this extremity the constancy and resolution of a general may recover a complete victory. There are innumerable instances where the party that gave least way to despair was esteemed the conqueror. For where losses and advantages seem nearly equal, he is reputed to have the superiority who bears up against his misfortunes with greatest resolution. He is therefore to be first, if possible, to seize the spoils of the slain and to make rejoicings for the victory. Such marks of confidence dispirit the enemy and redouble your own courage.

“Yet notwithstanding an entire defeat, all possible remedies must be attempted, since many generals have been fortunate enough to repair such a loss. A prudent officer will never risk a general action without taking such precautions as will secure him from any considerable loss in case of a defeat, for the uncertainty of war and the nature of things may render such a misfortune unavoidable. The neighborhood of a mountain, a fortified post in the rear or a resolute stand made by a good body of troops to cover the retreat, may be the means of saving the army.
“An army after a defeat has sometimes rallied, returned on the enemy, dispersed him by pursuing in order and destroyed him without difficulty. Nor can men be in a more dangerous situation than, when in the midst of joy after victory, their exultation is suddenly converted into terror. Whatever be the event, the remains of the army must be immediately assembled, reanimated by suitable exhortations and furnished with fresh supplies of arms. New levies should immediately be made and new reinforcements provided. And it is of much the greatest consequence that proper opportunities should be taken to surprise the victorious enemies, to draw them into snares and ambuscades and by this means to recover the drooping spirits of your men. Nor will it be difficult to meet with such opportunities, as the nature of the human mind is apt to be too much elated and to act with too little caution in prosperity. If anyone should imagine no resource is left after the loss of a battle, let him reflect on what has happened in similar cases and he will find that they who were victorious in the end were often unsuccessful in the beginning.
The Roman legionnaires were more notorious for their brutality than the Greeks. The remnants of Alexander's armies were turned into dismembered corpses in a campaign in 199 B.C. According to one Roman historian soldiers were ordered by their superiors "to kill everyone they met and to spare no one, and not to start looting until they received their order. The purpose of this custom was to strike terror...not only human beings [were] slaughtered, but even dogs were sliced in two and the limbs of other animals were cut off." Cities often surrendered before they could be slaughtered. Cicero said that “obeying rules of war and refraining from cruelty was what set men apart from beasts." He was killed by Roman soldiers.

The visual narrative at the top of Trajan’s Column depicts Emperor Trajan (A.D. 98–117) and his soldiers triumph over the Dacians. In one scene Trajan watches a battle, while two Roman auxiliaries present him with severed enemy heads. In another scene Roman soldiers load plunder onto pack animals after defeating Decebalus, the Dacian king.
On the Roman response to the Spartacus slave revolt (71 B.C.), Appian wrote: “Some say that Crassus, too, having engaged in battle with his whole army, and having been defeated, decimated the whole army and was not deterred by their numbers, but destroyed about 4,000 of them. Whichever way it was, he demonstrated to them that he was more dangerous to them than the enemy. Presently he overcame l0,000 of the Spartacans, who were encamped somewhere in a detached position, and killed two-thirds of them. He then marched boldly against Spartacus himself, vanquished him in a brilliant engagement, and pursued his fleeing forces to the sea, where they tried to pass over to Sicily. He overtook them and enclosed them with a line of circumvallation consisting of ditch, wall, and paling. [Source: Appian, (A.D. 95-165), “The Civil Wars”, 111]
“The battle was long and bloody, as might have been expected with so many thousands of desperate men. Spartacus was wounded in the thigh with a spear and sank upon his knee, holding his shield in front of him and contending in this way against his assailants until he and the great mass of those with him were surrounded and slain. The remainder of his army was thrown into confusion and butchered in crowds. So great was the slaughter that it was impossible to count them. The Roman loss was about 1,000. The body of Spartacus was not found. A large number of his men fled from the battlefield to the mountains and Crassus followed them thither. They divided themselves in four parts, and continued to fight until they all perished except 6000, who were captured and crucified along the whole road from Capua to Rome.” [Source: Appian, (A.D. 95-165), “The Civil Wars”, 111]
Maxims from De Re Militari
Flavius Vegetius Renatus wrote in “De Re Militari”: “It is the nature of war that what is beneficial to you is detrimental to the enemy and what is of service to him always hurts you. It is therefore a maxim never to do, or to omit doing, anything as a consequence of his actions, but to consult invariably your own interest only. And you depart from this interest whenever you imitate such measures as he pursues for his benefit. For the same reason it would be wrong for him to follow such steps as you take for your advantage. [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.

“The more your troops have been accustomed to camp duties on frontier stations and the more carefully they have been disciplined, the less danger they will be exposed to in the field.
“Men must be sufficiently tried before they are led against the enemy.
“It is much better to overcome the enemy by famine, surprise or terror than by general actions, for in the latter instance fortune has often a greater share than valor. Those designs are best which the enemy are entirely ignorant of till the moment of execution. Opportunity in war is often more to be depended on than courage.
“To debauch the enemy's soldiers and encourage them when sincere in surrendering themselves, is of especial service, for an adversary is more hurt by desertion than by slaughter.
“It is better to have several bodies of reserves than to extend your front too much.
“A general is not easily overcome who can form a true judgment of his own and the enemy's forces.
“Valor is superior to numbers.
“The nature of the ground is often of nmore consequence than courage.
“Few men are born brave; many become so through care and force of discipline.
“An army is strengthened by labor and enervated by idleness.
“Troops are not to be led to battle unless confident of success.
“Novelty and surprise throw an enemy into consternation; but common incidents have no effect.
“He who rashly pursues a flying enemy with troops in disorder, seems inclined to resign that victory which he had before obtained.
“An army unsupplied with grain and other necessary provisions will be vanquished without striking a blow.
“A general whose troops are superior both in number and bravery should engage in the oblong square, which is the first formation.
“He who judges himself inferior should advance his right wing obliquely against the enemy's left. This is the second formation.
“If your left wing is strongest, you must attack the enemy's right according to the third formation.
“The general who can depend on the discipline of his men should begin the engagement by attacking both the enemy's wings at once, the fourth formation.
“He whose light infantry is good should cover his center by forming them in its front and charge both the enemy's wings at once. This is the fifth formation.
“He who cannot depend either on the number or courage of his troops, if obliged to engage, should begin the action with his right and endeavor to break the enemy's left, the rest of his army remaining formed in a line perpendicular to the front and extended to the rear like a javelin. This is the sixth formation.
“If your forces are few and weak in comparison to the enemy, you must make use of the seventh formation and cover one of your flanks either with an eminence, a city, the sea, a river or some protection of that kind.
“A general who trusts to his cavalry should choose the proper ground for them and employ them principally in the action.
“He who depends on his infantry should choose a situation most proper for them and make most use of their service.
“When an enemy's spy lurks in the camp, order all your soldiers in the day time to their tents, and he will instantly be apprehended.
“On finding the enemy has notice of your designs, you must immediately alter your plan of operations.
“Consult with many on proper measures to be taken, but communicate the plans you intend to put in execution to few, and those only of the most assured fidelity; or rather trust no one but yourself.
“Punishment, and fear thereof, are necessary to keep soldiers in order in quarters; but in the field they are more influenced by hope and rewards.
“Good officers never engage in general actions unless induced by opportunity or obliged by necessity.
“To distress the enemy more by famine than the sword is a mark of consummate skill.
“Many instructions might be given with regard to the cavalry. But as this branch of the service has been brought to perfection since the ancient writers and considerable improvements have been made in their drills and maneuvers, their arms, and the quality and management of their horses, nothing can be collected from their works. Our present mode of discipline is sufficient.
“Dispositions for action must be carefully concealed from the enemy, lest they should counteract them and defeat your plans by proper expedients.
“This abridgment of the most eminent military writers, invincible Emperor, contains the maxims and instructions they have left us, approved by different ages and confirmed by repeated experience. The Persians admire your skill in archery; the Huns and Alans endeavor in vain to imitate your dexterity in horsemanship; the Saracens and Indians cannot equal your activity in the hunt; and even the masters at arms pique themselves on only part of that knowledge and expertness of which you give so many instances in their own profession. How glorious it is therefore for Your Majesty with all these qualifications to unite the science of war and the art of conquest, and to convince the world that by Your conduct and courage You are equally capable of performing the duties of the soldier and the general!
Ben Macintyre of the Times of London wrote: “The Greek word for spook is the pleasingly anagrammatical skopos, and spies appear throughout Greek literature. In 405BC, for example, a Spartan spy at Aegospotami reported that the Athenians had failed to post a guard on the fleet, which was consequently attacked and destroyed. Like us, the Romans imagined they were too noble for the murky business of spying; but they came to accept that without a centralised intelligence system the future of the empire was in jeopardy. [Source: Ben Macintyre, Times of London, October 9, 2010]
Julius Caesar came, saw and conquered; and before that, he spied — rather inadequately. In 55BC, the Romans were suffering from what would now be called a critical intelligence deficit. Caesar wanted to invade Britain but knew very little about the inhospitable island off the coast of Gaul. So Caesar launched a covert operation to gather information on British customs, harbours and military tactics. Caesar's first invasion was a failure, in large part because of inadequate and faulty intelligence. His internal spies used advanced techniques, including codes and ciphers, but he never did quite get the hang of intelligence.Moments before he was assassinated, a list of the conspirators was thrust into his hand, but he failed to act swiftly enough, and did not live to regret it.
Instead of sending out covert agents to report on neighbouring tribes, until about AD100 the Romans preferred to rely on huge defences, ad hoc military scouting in enemy territory and fides Romana, mutual trust between Rome and its allies, which sent word if barbarians approached. There was no lack of domestic espionage inside Rome: every aristocrat had a private network of agents and informers. Not until the 2nd century AD did Rome organise an agency that might be called a secret service. These were the frumentarii, ancestors of the CIA, KGB and MI6.
A cadre of supply sergeants whose original function was to collect and distribute grain, they combined the roles of tax collector, courier, secret policeman, political assassin and spy, and were generally loathed. Emperor Diocletian eventually disbanded the frumentarii, but they were immediately replaced by the agentes in rebus (general agents, a deliberately vague title), responsible for internal security and external intelligence. Their task, as defined by Procopius, was to "gain the most speedy information concerning the movements of the enemy, seditions . . . and the actions of governors and other officials".
The Romans were as suspicious of the spy trade as we are, yet as the Roman world became increasingly unpredictable the future of that civilisation came to rest, in part, on the provision of good intelligence. Then, as now, spies occupied a contradictory position in society, feared but oddly glamorous, liable to corruption, regarded with mistrust by their political overlords but necessary for the security of the state. The 4th-century philosopher Libanius described the agentes as "sheepdogs who have joined the wolf pack".
The toga-and-dagger skulduggery of I, Claudius may seem distant and encrusted by myth, but in many ways the challenges of espionage and intelligence-gathering in the ancient world are similar to those facing the West today: distributing resources between conventional warfare and covert operations, policing internal sedition and reconciling the conflicting demands of secrecy and liberty. An intelligence agent could have no better training than a solid grounding in classics, Jonathan Evans, director-general of the British overseas spy agency MI5 told Iris, a magazine promoting Latin teaching in state schools: "I think that Sulla would have found a soul mate in some of the security chiefs I have met from despotic regimes elsewhere in the world." Evans is a classics graduate who utilized the insights of the Roman poet Juvenal, historian Suetonius, and Sulla, the Roman general with "the cunning of a fox" in his fight against al-Qaida.
