U.S. Army Major General Leonard Wood (1860 - 1927) served as the Army Chief of Staff between the years 1910 through 1914 and was relieved of that office by President Wilson, who was unnerved by his wariness concerning America's inability to wage a modern war. Having alienated the president and other prominent generals in Washington, he continued on this path by launching the "Preparedness Movement" a year later in which he established four volunteer army training camps across the country.
