LECTURES ON LAND WARFARE A TACTICAL MANUAL FOR THE USE OF INFANTRY OFFICERS An examination of the Principles which underlie the Art of Warfare, with illustrations of the Principles by examples taken from Military History, from the _Battle of Thermopylae_ B.C. 480, to the _Battle of the Sambre_ November 1-11, 1918 London William Clowes and Sons, Ltd. 94 Jermyn Street, S.W.1 1922 First printed March, 1922 {vii} PREFACE The Lectures in this volume are based upon the official Text-books issued by the Imperial General Staff and upon the works of recognised authorities on the Art of Warfare. The aim of the Author is to examine the Principles which underlie the Art of Warfare, and to provide illustrations from Military History of the _successes_ which have attended knowledge and intelligent application of Text-book Principles, and of the _disasters_ which have accompanied ignorance or neglect of the teaching provided by the Text-books. The "dry bones" of the official publications are clothed with materials which may be supplemented at will by the student of Military History, and the Lectures may thus, it is hoped, be of assistance to Infantry Officers, either in the course of their own studies, or as a convenient groundwork upon which the instruction of others may be based. The scope of the work may be gathered from the Table of Contents and from the Index, and it will be seen that the general Principles underlying the Art of Warfare are included in the scheme, while advantage has been taken of the revision of the official Text-books to incorporate in the Lectures the lessons gained from the experience of leaders in the Great War.
