Von Steuben, who spoke little English, ran the troops through a gamut of intense Prussian-style drills. He taught them to efficiently load, fire and reload weapons, charge with bayonets and march in compact columns of four instead of miles-long single file lines.
Von Steuben helped to prepare a manual called “Regulations for the Order and Discipline of the Troops of the United States,” also called the “Blue Book,” which remained the official training manual of the Army for decades.
