This is the manual United States Army cavalry instructors used to train cavalry troops during the American Civil War. Even if you're not a rider, this manual will help you understand the complexities of drills, marching, cavalry camps, formations, and charges, among other tactics. Originally written in 1861, this 1864 edition is little changed and is illustrated to explain formations and movements. It is little wonder that, despite the grousing of the enlisted men, drilling these tactics over and over and over is what made them work in battle and ultimately helped save lives.
