PREFACE. In pursuing the subject of cavalry tactics I found that, while certain principles were accepted as correct, I was not familiar with the battles in which these principles were RP plied. 1 believe it to be true that there is no modern prin ciple of cavalry tactics, which is accepted today as correct by any first-class military power, which was not fully illustrated r during the War of the Rebellion. No war which has occu ed since that time has, in any respect, added to the cavalry tac tics which were in daily use during that great struggle. I give it as my humble opinion that increased range of firearms and the addition of machine guns, increase the sphere of action of, and necessity for, well-organized cavalry that bicycles, motorcycles and automobiles will prove to be only valuable auxiliaries to cavalry in transporting information back to the rear, and thus saving an unnecessary expen diture of horse flesh and that while flying machines may bring information, by so doing they will widen the sphere of action of good cavalry and, more than ever before, as a result of such information, it will be necessary to have good cavalry ready to move on extremely short notice. In looking for examples to illustrate the tactical prin ciples of cavalry operations, I have drawn mostly from the Records of the Rebellion indicated in refere ces b y R. R., but have not endeavored to give exact quotations instead I have quoted only so much as is necessary ta illustrate the point involved. The illustrations are taken mostly after the opening campaign of I 863, at which time the Federal cavalry reached an4 efficient condition. At this time the Confed erate cavalry was at its best. Life and campaigns of Maj. Genl. j. E. B. Stuart, p. 257. The reason why tnore Federal than Confederate reports are quoted is because the former are much more numerous. Whenever a report states what happens to the enemy or the enemys losses, be the report Federal or Confederate, that portion of it should be accepted with great caution. While the work principally treats of tactics, I have incorporated reports of such facts and expedients as are use ful for every cavalryman to know. It is my intention to follow this work, Part I, with a work on Troop Leading of Cavalry, wherein the decisions are based on the principles herein illustrated. This work is undertaken in the hope that the lessons learned during our great war will not be forgotten. Camp Stotse lburg, Parnpanga, P. I. March 3 1, 1910. INTRODUCTION.
