the first virtue in a soldier is endurance of fatigue; courage is only the second virtue

The spirit and other moral qualities which animate an Army, a General, or Governments, public opinion in provinces in which a War is raging, the moral effect of a victory or of a defeat, are things which in themselves vary very much in their nature, and which also, according as they stand with regard to our object and our relations, may have an influence in different ways.

Although little or nothing can be said about these things in books, still they belong to the theory of the Art of War, as much as everything else which constitutes War. For I must here once more repeat that it is a miserable philosophy if, according to the old plan, we establish rules and principles wholly regardless of all moral forces, and then, as soon as these forces make their appearance, we begin to count exceptions which we thereby establish as it were theoretically, that is, make into rules; or if we resort to an appeal to genius, which is above all rules, thus giving out by implication, not only that rules were only made for fools, but also that they themselves are no better than folly.

The valor of a country may be learned by the bravery of its soldiery, and the general cast of its inhabitants, but confidence of success is best discovered by the active measures pursued by men of property; and when the spirit of enterprise becomes so universal as to act at once on all ranks of men, a war may then, and not till then, be styled truly proper.

Let us be, then, warriors of the heart, and enlist in our inner cause the virtues we have acquired through blood and sweat in the sphere of conflict — courage, patience, selflessness, loyalty, fidelity, self-command, respect for elders, love of our comrades (and of the enemy), perseverance, cheerfulness in adversity and a sense of humor, however terse or dark.

The first virtue in a soldier is endurance of fatigue ;
courage is only the second virtue.

...It is a proud privilege to be a soldier – a good soldier … [with] discipline, self-respect, pride in his unit and his country, a high sense of duty and obligation to comrades and to his superiors, and a self confidence born of demonstrated ability.

The principle on which to manage an army is to set up one standard of courage which all must reach.

Discipline is the soul of an army. It makes small numbers formidable; procures success to the weak, and esteem to all

Without risks or prizes for the darer, history would be insipid indeed; and there is a type of military character which every one feels that the race should never cease to breed, for everyone is sensitive to its superiority. The duty is incumbent on mankind, of keeping military character in stock — if keeping them, if not for use, then as ends in themselves and as pure pieces of perfection, — so that Roosevelt's weaklings and mollycoddles may not end by making everything else disappear from the face of nature.

An army has to be trained, disciplined, and organized so that it is a meaningful unit in peace and in war.

...the basic principles of the military services are unchangeable. Courage and candor, obedience and comradeship, love of fatherland and loyalty to the State: these are ever the distinguishing characteristics of the soldier and sailor. Building character through intelligent training and education is always the first and greatest goal.

The Way of the warrior is to master the virtue of his weapons.

The war-party is assuredly right in affirming and reaffirming that the martial virtues, although originally gained by the race through war, are absolute and permanent human goods. Patriotic pride and ambition in their military form are, after all, only specifications of a more general competitive passion. They are its first form, but that is no reason for supposing them to be its last form. Men are now proud of belonging to a conquering nation, and without a murmur they lay down their persons and their wealth, if by so doing they may fend off subjection. But who can be sure that other aspects of one's country may not, with time and education and suggestion enough, come to be regarded with similarly effective feelings of pride and shame? Why should men not some day feel that is it worth a blood-tax to belong to a collectivity superior in any respect? Why should they not blush with indignant shame if the community that owns them is vile in any way whatsoever? Individuals, daily more numerous, now feel this civic passion. It is only a question of blowing on the spark until the whole population gets incandescent, and on the ruins of the old morals of military honor, a stable system of morals of civic honor builds itself up. What the whole community comes to believe in grasps the individual as in a vise. The war-function has grasped us so far; but the constructive interests may some day seem no less imperative, and impose on the individual a hardly lighter burden.

Independent thinking is not encouraged in a professional Army. It is a form of mutiny. Obedience is the supreme virtue. Theirs not to reason why. Orders are to be carried out and not canvassed. Criticism is insubordination. The object of discipline is to accustom men to respond to a command instantly, by instant action, without thought of effect or consequence. There were many intelligent officers and men who knew that the orders given them during the War were utterly stupid and must have been given by Staffs who had no understanding of the conditions. But orders were orders. And with their men they went to a doom they foresaw was inevitable. Such an instinctive obedience to the word of command is essential to the efficiency of a body of men who have to face terror, death or mutilation in the discharge of their terrible duties. But a long course of mental subservience and suppression cramps the development and suppleness of the intellect. It makes "an officer and a gentleman" but it is not conducive to the building up of an alert, adaptable and resourceful leader of men.
