This volume was originally published in Berlin in 1920. I have followed the same guidelines here as in my translations of the first three volumes. It should be noted that, in the many references to strategy, I have translated Ermattungs-Strategie as “strategy of attrition,” and Niedenverfungs-Strategie as “strategy of annihilation,” the same terms I used in the preceding volumes. While some readers may prefer other terminology, I believe the meaning is clear in each case. In the occasional references to the varying minimum requirements for the height of soldiers, it should be remembered that the foot and inch were not standard measurements throughout Europe, and a height mea surement of 5 feet, 7 inches, for example, is not the equivalent of those figures in British or American usage. Once again I am indebted to Dr. Everett L. Wheeler for his translations of the Latin passages appearing in the text. Finally, I take heartfelt pleasure in expressing my gratitude to my wife Ruth, who not only wrote out the translation of each of the last three volumes as I dictated but also bore the long ordeal with great patience. Preface This fourth and last volume of the History of the Art of War is appearing in the year in which the greatest of all wars has just ended. The research for this volume was practically complete in 1914, and the work was in large part already composed at that time. But the storm into which we were plunged, instead of spurring me on to complete this task and finish this subject, as one might have imagined, drew my attention away from it. I interrupted my work, only to bring it finally to completion without constructing a bridge between it and the present. Whenever it is a question in this book of the conditions of our time, this means the period before the World War, in which I was actually writing, and occasionally also the period in which I myself gained practical knowledge of warfare. (In 1867 I became a soldier and was discharged in 1885 as a first lieutenant of reserves.) Originally, I planned to have my work finish with the German wars of unification and to add a presentation of the development of the Na poleonic strategy into that of Moltke. But I dropped this idea, since it would have led directly into the problems of the World War, which are not yet sufficiently well defined for a scholarly treatment in the spirit of this work. That does not mean that I would not risk devoting any con sideration at all to the latest period but only that it cannot yet be done in the systematic, detached manner which a work of this kind requires. Consequently, this work ends with Napoleon and his contemporaries. The continuation up to the present time, however, is already at hand, even though in another form. What I have to say and have been able to say concerning the phenomena of military history of the later nineteenth century, especially about Moltke’s strategy and the events of the World War, has been written in individual articles and in the three volumes of the collection War and Politics, 1914 to 1918 {Krieg und Politik, 1914 his 1918), which are being published at the same time as this book. The Moltke articles appear in the collection Recollections, Articles, and Speeches (Erinnerungen, Aufsätze und Reden), supplemented by an article con
