Fear j We start with man physical and man mental ; he must possess the will to fight and the power to move, the connecting link is the principle of determination or the will to win. He must possess the moral to hit and the power to hit, here the connecting link is the principle of endurance. He must endow his adversary with a fear which will force him to protect himself or seek pro- tection, which is acknowledgment of lack of endurance (temporary or permanent) , and inferiority of determination ; here the connecting link is the principle of demoralization. Thus, we see that, in war, the " will to win " is the power of being able to endure and to demoralize, and that the three psychological 44 The Reformation of War elements are not " things in themselves " but coefficients of the elements of war — movement, weapons and protection. As 1 have dealt at some length with the principles of war, it is only fitting that I should now examine these psychological principles, for they are no less important. Briefly, the following are my views : (i.) The Principle of Determination. The limits of the principle of determination are first defined by the national objective of war, and secondly by its military objective. Between these two boundaries this principle operates. From the national point of view, there is the will to impose upon the enemy's government a policy distasteful to it ; this policy must be clean cut, for on its stability rests the military objective, which psychologically is the " will to win." Sub- jectively, this will is concentrated in the mind of the commander, whose plan of action is the means of enforcing the national policy ; this plan must also be clean cut, that is to say it must be so simple that its very nature will give rise to the fewest possible complexities. As the stability of this plan will depend on the stability of the policy, the commander-in-chief must not only be acquainted with the nature of this policy, but with any changes rendered necessary through fluctuations in national conditions. Inversely, any changes in plan will entail modi- fications in policy ; consequently, we find that both the plan and the policy are correlatives, that is they are dependent on each other's stability. Now, as every policy must be plastic enough to admit of fluctuations in national conditions, so must each plan be plastic -enough to receive the impressions of war, that is power to change its shape without changing or cracking its substance. This plasticity is determined psychologically by the condition of mentality in the two opposing forces. There is the determination between the two commanders-in-chief, and between them and their men, and, ultimately, between the two forces themselves. The " will to win " is, therefore, first of all a duel between two brains each controlling a weapon called an army ; and secondly, a struggle between two armies The Science and Art of War 45 each equipped with various types of weapons. If all these various weapons, each influencing in its own degree the mentality of its wielder and that of his opponent, can be reduced in number, the principle of determination becomes more simple in application. If, again, similarity of protection becomes possible, simplicity is increased ; and if, finally, similarity of movement can be added, physically the simplest form of army is evolved. I will now examine the psychological side. If the will and moral of each individual can be brought to a high but equal level and his fear to a low and equal level, the commander-in-chief will possess known qualities out of which to construct his plan. It will be seen, therefore, that, in its broadest sense, the principle of determination is the simplification of the means so that the will of both the chief and his men may become operative. (ii.) The Principle of Endurance. Springing directly from the principle of determination is the great principle of endurance . The will of the commander-in-chief and the will of his men must endure, that is the}' must continue in the same state. It is the local conditions, mental and material, which continually weaken this state and in war often threaten to submerge it. To the commander endurance consists, therefore, in power of overcoming conditions — by foresight, judgment and skill. These qualities cannot be cultivated at a moment's notice, and the worst place to seek their cultivation is on the battlefield itself. The com- mander-in-chief must be, therefore, a mental athlete, his dumb- bells, clubs and bars being the elements of war and his exercises the application of the principles of war to the conditions of in- numerable problems. Collectively, in an army, endurance is intimately connected with numbers, and, paradoxical as it may seem, the greater the size of an army the less is its psychological endurance. The reason for this is a simple one : one man has one mind ; two men have three minds — each his own and a crowd mind shared be- tween them ; a million men have millions and millions and millions of minds. If a task which normally requires a million men can be carried out by one man, this one man possesses 46 The Reformation of War psychologically an all but infinitely higher endurance than any single man out of the million. Man, I will again repeat, is an encumbrance on the battlefield, psychologically as well as physically ; consequently, endurance should not be sought in numbers, for one Achilles is worth a hundred hoplites. (iii.) The Principle of Demoralization. As the principle of endurance has, as its primary object, the security of the minds of men by shielding their moral against the shock of battle, in- versely the principle of demoralization has as its object the de- struction of this moral : first, in the moral attack against the spirit and nerves of the enemy's nation and government ; secondly against this nation's policy ; thirdly against the plan of its com- mander-in-chief, and fourthly against the moral of the soldiers commanded by him. Hitherto the fourth, the least important of these objectives, has been considered by the traditionally- minded soldier as the sole psychological objective of this great principle. In the last great war the result of this was, as I shall show presentfy, that the attack on the remaining three only slowly evolved during days of stress and because of a faulty appreciation of this principle during peace time. I will now turn to the psychological conditions of war. In considering these it must first be realized that all conditions are, in part at least, psychological. That is to say they stimulate the brain in a greater or lesser degree ; but while hundreds affect war materially, such as roads for supply and the influence of gravity on the flight of projectiles, thousands more directly affect the mind of the soldier, and through his mind his body, and through his body his actions. Psychologically, we may divide these conditions into three general categories : those which are common to men either individually or collectively ; those which affect the soldier as an individual, and those which affect a mass of soldiers as a homogeneous crowd. The following are examples of these categories : (i.) General Conditions : Safety, comfort, fatigue, catch- words, loyalty, honour, faith, hatred and cheerfulness. The Science and Art of War 47 (ii.) Individual Conditions : Knowledge, skill, determination, endurance, courage, imagination, confidence, talent and sense of duty. (iii.) Collective Conditions : Suggestion, intuition, supersti- tion, esprit de corps, tradition, moral, education, patriotism and comradeship. I do not propose to analyse these conditions as it would take a long time to do so, nevertheless it should be remembered that the psychological principles in war cannot be applied correctly unless the conditions which go to build up soldiership have been stabilized, long prior to war, in days of peace. The process whereby this stability is effected is called training. Training forms the true foundation of battle, which should be a continuation of the soldier's education, just as war itself should be a continuation of peace policy. For this to be possible it will be at once seen that training should not be based solely on the known conditions of past wars, but above all on the probable conditions of the next war. That, consequently, these conditions must be foreseen ; therefore, on the correctness of their forecasting will, to a great extent, depend the continuity of peace training in the form of battle tactics when war breaks out. Once we have diagnosed the conditions of the next war, then, by applying to them the psychological principles, we shall build up a scientific system of training. In fact, we shall start winning our battle.? from to-day onwards on the barrack square and in the class-room. Training, such as this, may well be called the art of war, the foundations of which I will now inquire into. In analysing tactics, or the art of fighting, the military student usually visualizes the battle as a " thing in itself." The correct appreciation is diametrically opposite, for battles consist of a complex series of individual fights, each compounded of the ele- ments of war operating concentrically round the problem of how to give blows without receiving them. This problem may be divided into four sub-problems, which every commander should consider prior to an operation taking place. 48 The Reformation of War These four problems are : (i.) How to keep men alive ? (ii.) How to keep movement alive ? (iii.) How to keep weapons alive ? (iv.) How to keep moral alive ? As the commander has four problems to solve so also has the soldier. He has : (i.) To hit his enemy while at a distance from him. (ii.) To move towards him. (iii.) To hit him at close quarters. (iv.) To avoid being hit throughout this engagement. The whole of these eight problems are in nature protective, and they form the foundations of offensive power, which endow it with stability of action as well as security during action and after defeat. I cannot here do more than glance at this fundamental pro- blem of battle organization : how to organize an army so that it possesses power of stability and mobility. Briefly it may be explained as follows : As the bones of man's body give stability to his muscular movement, so must every force of soldiers possess within their organization certain troops which can resist attack and certain others which can develop their mobility out of this resistance. The battle of Crecy was virtually won by the English archers, the mobile element. They could not, however, have accomplished what they did had not the men-at-arms and dis- mounted knights formed a stable base from which they were able to develop the full power of their bows. A scientifically organized army is one which possesses a brain and a body, both of which possess a positive and a negative pole, stability and mobility. The stability of the brain is its faculty of reason based on know- ledge, and its mobility the faculty of imagination based on the products of reason. The military body is divided into two main forces : those which disorganize the enemy's brain and body — that is, break down its stability, and those which annihilate the broken fragments. Each fraction of this body must possess power to The Science and Art of War 49 resist movement and power to develop movement. Its mobility depends on a combination of weapons and movement, and its stability upon that of weapons and protection. From these two — its stability and mobility, are its offensive and protective powers reciprocally developed. Thus, in the hands of man, do we see a harmonious inter-relation between the three physical elements of war, and, according to the degree of harmony attained, do the plans of man succeed or fail. This brings us to the problem of grand tactics or battle planning. In every plan the first question is to decide on the objective. In physical warfare the military objective is the defeat of the enemy's army, so that the will of his government may be at- tacked. Where, then, is the decisive point, the point at which the enemy may most economically be defeated ? The schoolmen answer : " The decisive point depends on circumstances," and some suggest a flank and others a central objective. The school- men, if they only thought in simpler terms than they are wont to do, could have long ago given a better answer to this question, which I will examine from a very simple point of view. Every organization has one great prototype — the body of man. When a boxer fights another he tries to get a left or right on the side of his opponent's jaw. Why ? Not to break the jaw, the external body, but to derange the brain, the internal organ, because more than any other organ the brain controls the body. The brain of an army is its command, and the command of an army is its decisive point, and no blow should be delivered with- out reference to this point. Though the brains of an army control its whole body, nevertheless the prevailing idea in tactics is one of brute force applied by weapons to the enemy's battle body. Batter the enemy's muscles blue and black and get battered black and blue in return, is the traditional method, and then only, when one side is rendered physically impotent, attack the brains ! I fully agree that more often than not it is impossible to strike straight to the jaw because our opponent carefully protects his chin. This does not, however, vitiate the fact that the decisive point is the command of the opposing army, and that the more 4 50 The Reformation of War the enemy is forced to protect it, the less will he be able to hit out. The elements of grand tactics are in essence very simple, once the decisive point has been agreed upon. The object is either to paralyse or disintegrate the enemy's command, which may be carried out by four acts, separate or combined. These four acts are : (i.) Surprise. An enemy may be surprised, which implies that he is thrown off his balance. This is the best method of defeating him, for it is so economical, one man taking on to him- self the strength of many. Surprise may be considered under two main headings : surprise effected by doing something that the enemy does not expect, and surprise effected by doing some- thing that the enemy cannot counter. The first may be denoted as moral surprise, the second as material. (ii.) Envelopment. An enemy may be enveloped and so placed at a severe disadvantage. Envelopment, whether ac- complished by converging or overlapping, presupposes a flank, a flank which may be tactically rolled up, or, if turned, will expose the command and lines of communications behind it. The attack by envelopment is a very common action in war, which more often than not has led to victory. (hi.) Penetration. An enemy's front may be penetrated in order directly to threaten his lines of communications behind it, or to hit at his command, or to create a flank or flanks to be enveloped. Normally, when once a hostile front is broken, the two sections are rolled up in opposite directions to each other, or one is held while the other is hammered ; an operation which, if carried out successfully, usually leads to a total disintegration of the enemy's strength. (iv.) Attrition. An enemy may be worn out by physical and moral action ; this, though the usual method of defeating him, is also, frequently, the most uneconomical method, for the process of disintegration is mutually destructive. Outside these four grand tactical acts of battle there is little to be learnt in grand tactics. The Science and Art of War 51 Once the direction of the decisive attack is fixed, the grand tactical plan is arrived at by applying the principles of war to the conditions under which war has to be waged ; in other words, liberty of movement has to be gained. Free movement, which is the object of all strategy, is conditioned not only by impulse but by the form of the object moved. In war, the will of the com- mander is the impulse, and the strategical distribution of his army the form of the military projectile, which should nor malty, like an arrow-head, be triangular, the main force in rear of it operating like the shaft behind the head. Generally this head consists of an advanced guard and two wings. The secret of all economical military formations is that they must possess a harmon}^ of offensive and defensive power through move- ment, movement in its broadest sense being " locomobility," that is freedom of movement in all directions. Liberty of movement is the basis of liberty of action, which is a compound formed out of superiority in the elements of war. It is the foundation of minor tactics and consists of the follow- ing values : ( Superiority of will. (i.) Man - Superiority of endurance. ( Continuity of co-operation. ( Superiority of speed. (ii.) Movement
