This book is Volume II in a series titled "The Horse Soldier: 1776-1943", which covers in detail the United States Cavalryman - His uniforms, arms, accoutrements, and equipment.  Every illustration in this multi-volume work has been drawn by the author from original materiel.  Where relevant, the complete text of regulations is quoted. Volume Three reprints the complete uniform regulations in the teens, not just the portion on mounted men.  This series is not just on the mounted horse cavalry so celebrated in John Wayne movies, but covers all the mounted troops, dragoons, mounted rifles, and cavalry in the period of the frontier expansion, before the Civil War, then both North and South, and the post war frontier patrolling days. Not only is the equipment, both individual and horse, of the cavalryman covered, so is that of the artillery man where it differed. The coverage is relevant to all mounted men--engineers, signalers, and hospital corpsmen, and their clothing and equipment.
