"This absence of similarity among military questions naturally brings out the inability of memory to solve them; also the sterility of invariable forms, such as figures, geometrical drawings (épures), plans (schémas), etc. One only right solution imposes itself : namely, the application, varying according to circumstances, of fixed principles."
"To be disciplined does not mean being silent, abstaining, or doing only what one thinks one may undertake without risk; it is not the art of eluding responsibility; it means acting in compliance with orders received, and therefore finding in one's own mind, by effort and reflection, the possibility to carry out such orders. It also means finding in one's own will the energy to face the risks involved in execution."
"The truth is, no study is possible on the battle-field; one does there simply what one can in order to apply what one knows. Therefore, in order to do even a little, one has already to know a great deal and to know it well."
"There is but one means to extenuate the effects of enemy fire: it is to develop a more violent fire oneself."
"To inform, and, therefore to reconnoitre, this is the first and constant duty of the advanced guard."
"An army is to a chief what a sword is to a soldier. It is only worth anything in so far as it receives from him a certain impulsion (direction and vigour)."
"Every manoeuvre must be the development of a scheme; it must aim at a goal."
"I was convinced then—and my conviction has not since faltered—that the Treaty [of Versailles] then in the making, which I was not allowed to modify, was bad for the safety of France. Very bad. It was full of flaws, it was fundamentally wrong, and cannot fail one day to have the worst results. On the day when it is apparent in all its evil, when France perceives that her interests were improperly defended, she will rise in deep anger against those who so imperfectly handled that defence."
"Les avions sont des jouets intéressants mais n'ont aucune utilité militaire"
"One single private soldier, and we would take good care that he was killed."
"This is not a peace. It is an armistice for 20 years."
"In tactics, action is the governing rule of war."
"The laurels of victory are at the point of the enemy bayonets. They must be plucked there; they must be carried by a hand-to-hand fight if one really means to conquer."
"Against what should fire be opened? Against the obstacles which may delay the march of infantry. The first obstacle is the enemy gun. It will be the first objective assigned to artillery masses."
"When the moment arrives for taking decisions, facing responsibilities, entering upon sacrifices — decisions which ought to be taken before they are imposed, responsibilities which ought to be welcomed, for the initiative must be secured and the offensive launched — where should we find a man equal to these uncertain and dangerous tasks were it not among men of a superior stamp, men eager for responsibilities? He must indeed be a man who, being deeply imbued with a will to conquer, shall derive from that will (as well as from a clear perception of the only means that lead to victory) the strength to make an unwavering use of the most formidable rights, to approach with courage all difficulties and all sacrifices, to risk everything; even honour — for a beaten general is disgraced for ever."
"The distribution of troops devoted to the defence of a place includes a garrison, an occupying force, numerically as weak as possible; a reserve as strong as possible, designed for counterattacking and for providing itself, at the moment it goes into action, with a security service which will guard it from any possible surprise."
"In a time such as ours when people believe they can do without an ideal, cast away what they call abstract ideas, live on realism, rationalism, positivism, reduce everything to knowledge or to the use of more or less ingenious and casual devices — let us acknowledge it here — in such a time there is only one means of avoiding error, crime, disaster, of determining the conduct to be followed on a given occasion — but a safe means it is, and a fruitful one; this is the exclusive devotion to two abstract notions in the field of ethics: duty and discipline; such a devotion, if it is to lead to happy results, further implies besides… knowledge and reasoning."
"In war there are none but particular cases; everything has there an individual nature; nothing ever repeats itself. In the first place, the data of a military problem are but seldom certain; they are never final. Everything is in a constant state of change and reshaping."
"Men called to the conduct of troops should prepare themselves to deal with cases more and more varied upon an ever-increasing horizon of experience. They can only be given the capacity to arrive at a prompt and judicious position by developing in them through study their power of analysis and of synthesis; that is, of conclusion in a purely objective sense, conclusion upon problems which have been actually lived and taken from real history. Thus also can they be founded through the conviction that comes from knowledge in a confidence sufficient to enable them to take such decisions upon the field of action."
"The unknown is the governing condition of war."
"A war not only arises, but derives its nature, from the political ideas, the moral sentiments, and the international relations obtaining at the moment when it breaks out. This amounts to saying : try and know why and with the help of what you are going to act; then you will find out how to act."
"The military art is not an accomplishment, an art for dilettante, a sport. You do not make war without reason, without an object, as you would give yourself up to music, painting, hunting, lawn tennis, where there is no great harm done whether you stop altogether or go on, whether you do little or much. Everything in war is linked together, is mutually interdependent, mutually interpenetrating. When you are at war you have no power to act at random. Each operation has a raison d'etre, that is an object; that object, once determined, fixes the nature and the value of the means to be resorted to as well as the use which ought to be made of the forces."
"The Prussian Army has no ideals, no true spiritual strength; neither has the whole nation. All they have is gross materialism. ... The German soul has a place for the glorification of brute force, for the notion of war as a colossal looting campaign. That is all it holds. It is not much."
"What you must do is to avoid the outbreak of war; do not tempt nations to become your adversaries. The best, indeed, the only means to this end are solid frontiers and an excellent army."
"All her principles are based on one idea, namely: That right and morality are not the same for all, that there are privileged individuals who may deliver themselves from their shackles. It is a wicked theory; it cannot be too strongly opposed. From head to heel, Germany was tainted with this spirit. It assumed the importance of a dogma. ... The worst means were sanctified by her if used to this end."
"There you have a country against which the Allies must take well-defined precautions. It is possible that its republican form of government will profoundly modify the German mentality. I devoutly hope so, but we cannot be sure. A well-organized, militarized Republic, however, might be as great a menace to its neighbours as the old Empire—although as yet we have no proof that the Republic can establish itself firmly in Germany."
"One does simply what one can in order to apply what one knows."
"Mon centre cède, ma droite recule, situation excellente, j'attaque."
"What you did was the greatest thing accomplished by any private soldier of all of the armies of Europe."
"I stressed the importance always attached by Moltke to the Rhine question. I summarized his principle thus: ‘The bone of contention between Paris and Berlin is the Rhine; whichever holds the river is certain of dominating the other.’ ... To keep the 1914 frontier open to a menace aggravated by the destruction of Russia, and to expose France once more to the devastation she has suffered during the last five years, would be a crime against our country. There is only one remedy: the occupation of the Rhine."
"The most powerful weapon on earth is the human soul on fire."
"Haig clearly took a desperate view of the position... Pétain expressed an identical opinion about the same time to Clemenceau, and according to Poincaré was actually ordering a retreat of the French Army to the south. Clemenceau had agreed with Pétain. It would look, therefore, as if the two Commanders at this Conference on the evening of the 24th had come to the same conclusion. The supreme courage of Foch saved the situation. This was the greatest moment in his career."
"I met General Foch... He corresponded more with the British idea of what a typical Frenchman is like—vivacious, demonstrative, emphatic and gesticulatory. He talked just as much with his hands and arms as he did with his tongue. But whether he expressed himself with hand or voice he always talked well and to the point. His high broad forehead and his penetrating eye proved him a man of exceptional gifts. I asked him if he had any message for the British Cabinet and he said, "Tell them there will be no more retreats." I asked him whether I could also tell them there would be any more advances. He hesitated and was evidently perplexed by the question. After a perceptible halt he replied: "That depends on the men and material you will be able to throw into the battle line." He said that the Belgians had been obliged to retreat before the German advance, but his advice to them had been, "If you want to keep your country, dig yourselves into it, and hang on to it!""
"France had been bled white by the war. The generation that had dreamed since 1870 of a war of revenge had triumphed, but at a deadly cost in national life-strength. It was a haggard France that greeted the dawn of victory. Deep fear of Germany pervaded the French nation on the morrow of their dazzling success. It was this fear that had prompted Marshal Foch to demand the Rhine frontier for the safety of France against her far larger neighbour. But the British and American statesmen held that the absorption of German-populated districts in French territory was contrary to the Fourteen Points and to the principles of nationalism and self-determination upon which the Peace Treaty was to be based. They therefore withstood Foch and France. They gained Clemenceau by promising: first, a joint Anglo-American guarantee for the defence of France; secondly, a demilitarised zone; and thirdly, the total, lasting disarmament of Germany. Clemenceau accepted this in spite of Foch’s protests and his own instincts. The Treaty of Guarantee was signed accordingly by Wilson and Lloyd George and Clemenceau. The United States Senate refused to ratify the treaty. They repudiated President Wilson’s signature. And we, who had deferred so much to his opinions and wishes in all this business of peacemaking, were told without much ceremony that we ought to be better informed about the American Constitution."
"[On 25 March 1918 there was] a Conference held at Pétain's Headquarters, Clemenceau, Loucheur, Pétain and Foch being also present. Pétain took a very pessimistic view... Foch, who seems to have spoken with energy and determination, took a different view of the situation. He thought the danger of the German push to break in between the French and British in the direction of Amiens was so formidable that risks must be taken in other directions. In his opinion, even more divisions must, if possible, be thrown in, and, by a great effort, this might be done more quickly than Pétain thought possible. It is in an emergency that the real quality of a man comes out. In front of this grave crisis both Pétain and Haig were bewildered and incapable of the action which a desperate situation demanded, but Foch rose to the occasion with the might of a giant. That accounts for the complete change which Milner found in the attitude of both Commanders-in-Chief towards this great old General. They were now anxious to retrace the fatal steps they had conjointly taken on the Versailles decision and to secure the help of Foch to extricate them from the dilemma in which their repudiation of his supremacy had landed the Allied Armies."
"None but a coward dares to boast that he has never known fear."
"A radish will never stand in the way of victory."
"He (Clemenceau) broke off to confide in me sadly that General Pétain was contemplating the retreat of the French Army to the south while the British Army retired towards the north. Pétain, added Clemenceau, had given orders on this basis. Foch confirmed this last piece of information and told me of the order to retreat which Pétain had given. "The President of the Council (Clemenceau)," added Foch, "has only just lately begun to take part in military matters; he had accepted Pétain's point of view, but I declined to take any responsibility for it. I sent M. Clemenceau a note to tell him my views. Common sense indicates that when the enemy wishes to begin making a hole, you do not make it wider. You close it, or you try to close it. We have only got to try and to have the will; the rest will be easy. You stick to your ground, you defend it foot by foot. We did that at Ypres, we did it at Verdun." And Foch stuck to his point with the same energy before Clemenceau, the senator and the deputy."
"Weygand tells us that many of his visitors, French and foreign, were rather shy at finding themselves in the presence of the Chief who had commanded millions of men, and whose name for eight months had embodied all the trust and all the hopes of the Allied nations, the victor in the greatest battle in history. They left his presence impressed by the greatness of his intellect and of his soul, and fascinated by his simplicity. "They made no mistake; they had been in the presence of true greatness, with which there is always simplicity.""
"The will to conquer is the first condition of victory."
"A four years' war and the subsequent peace have divided Europe into two sections, the winners and the losers. The winners have even less reason to make war than in 1914. Peace will never be threatened by them. Does that hold true also of the losers? Have they resigned themselves to their defeat and the moral and material losses it entails? Who can say? Germany, for instance, was for centuries moulded in character and instincts by Prussia, who regarded war as a lucrative national industry; she will experience much difficulty in changing her mentality and outlook."
"I am conscious of having served England as I served my own country."
"He rallied over and over again, and there was talk, at one time, of a move to the south of France, but it was not to be. When sitting in his chair by the window on the evening of Wednesday, the 20th of March, he was seized with a heart attack just before they were about to move him to his bed. Extreme unction according to the rites of his Church was administered by a priest from the neighboring church of St. Clotilde before he passed away, unconscious at the last, and Madame Foch was with him at the end. The closing of the shutters of his window told the outside world that all was over. Within half an hour there arrived tokens of sympathy, flowers and messages from the President, from members of the Government, and from the British Ambassador. The Chamber of Deputies was sitting at the time, and M. Poincaré, the Prime Minister, announced the death of the great Marshal, adding with emotion: "Marshal Foch was not only a great soldier, he was a great citizen. I know that the Chamber will associate itself with the national mourning." M. Flanderi, the Vice-President of the Chamber, said: "To try to make any eulogy of Marshal Foch would be to dim the glory which surrounds his memory in the thoughts of all his grateful countrymen. I am sure that I shall be interpreting Parliament's wishes in addressing our supreme homage to his memory and in sending our condolences to his family." Members of the Chamber were visibly moved as they filed out quietly. Within a few hours there arrived condolences and tributes to his memory from all parts of France and the peoples of foreign countries. It is said that the Marshal's last words were: "Allons-y"- Let us go. He was ready."
"I bluntly remarked to M. Klotz, the Finance Minister: ‘With the treaty you have just signed, sir, you can expect with certainty to be paid in monkey tricks.’"
"The Rhineland question is controlled by the Rhine. The river is the deciding factor. The master of the Rhine is the master of the surrounding country. Whichever side does not control the Rhine has lost."
"[O]ur Allies proposed the disarmament of Germany. It cannot be too often asserted that such a step would give us a mere temporary, precarious, illusory security. It is practically impossible to prevent Germany from arming herself in secret."
"Germany is about to join [the League of Nations]. It will be alleged that she conforms in spirit to that of the League. If you hope that she will desire to maintain the frontiers forced on her, which she has never acknowledged in her heart, and which, bluntly speaking, she loathes and yearns to destroy—if you can hope that, you must have more than your share of naïveté."
"[T]he treaty [of Versailles]...provided for a fifteen-year occupation of the Rhineland, with retreats every five years. Such a guarantee, I said without mincing my words, was ‘from the military point of view, null; it will merely be an increase of work for the Allied occupation.’ I went on to say that whereas the treaty was non-existent as promoter of our security, it was distinctly bad for reparations. ... I asked who would be judge of the situation if we sought to reoccupy the Rhineland because of an infringement of terms by Germany. The Commission for Reparations would not suffice, I said. It cannot be denied that I was right on this point."
"On Armistice Day, the German armies had marched homeward in good order. "They fought well," said Marshal Foch, Generalissimo of the Allies, with the laurels bright upon his brow, speaking in soldierly mood: "let them keep their weapons." But he demanded that the French frontier should henceforth be the Rhine. Germany might be disarmed; her military system shivered in fragments; her fortresses dismantled: Germany might be impoverished; she might be loaded with measureless indemnities; she might become a prey to internal feuds: but all this would pass in ten years or in twenty. The indestructible might "of all the German tribes" would rise once more and the unquenched fires of warrior Prussia glow and burn again. But the Rhine, the broad, deep, swift-flowing Rhine, once held and fortified by the French Army, would be a barrier and a shield behind which France could dwell and breathe for generations. Very different were the sentiments and views of the English-speaking world, without whose aid France must have succumbed. The territorial provisions of the Treaty of Versailles left Germany practically intact. She still remained the largest homogeneous racial block in Europe. When Marshal Foch heard of the signing of the Peace Treaty of Versailles he observed with singular accuracy: "This is not Peace. It is an Armistice for twenty years.""
"It was the crucible of 1940 that transformed the obscure colonel of the battle of France... He emerged from it with his qualities of courage and self-reliance, audacity and daring, but also with his defects of ingratitude, vindictiveness, duplicity and prejudice; all inherent in the metal, but turned into steel by the ordeals of that terrible summer. In 1940 he proclaimed himself Joan of Arc. It was not long after the Dakar fiasco that he told the British Foreign Secretary, "Je suis la France". ... He did not need to learn from Churchill a creed we sometimes seem to have forgotten but would do well to remember: boundless love of country and complete faith in its destiny... de Gaulle, absolutely alone, has rebuilt his shattered country on the ruins of defeat, and has made France stronger, and her influence greater, than it has been for a century."
