The breakout of hostilities with Spain over Cuba in 1898 also led to an increase in the size and improved equipment and training for the Ohio National Guard. Several regiments of infantry and artillery were formed and shipped to Tampa, Florida for training and eventual transport to the front lines in Cuba. Due to the rapid American success, the war ended prior to any of these units actually being deployed in a combat situation. The Spanish-American War thrust the United States into the role of a world power and both military and civilian leaders recognized that it was necessary to maintain a uniformly trained and armed military force. This reflected the slow evolution of the Ohio militia into a National Guard which in addition to being a state force for quelling civil disturbances, was assuming a key role in the national defense.
Leading the effort to accomplish this was Major General Charles Dick of the Ohio National Guard. After serving in the Spanish-American War he was later elected to the U.S. Senate where he was instrumental in passing the Dick Act of 1903. This benchmark legislation repealed the antiquated militia laws and effectively converted the various volunteer militias into the National Guard as we know it today. Under the Dick Act Guard units received increased federal funding and equipment. In return each state National Guard was required to conform to federal standards for training and organization. Rather than the periodic muster, each unit was expected to muster for a set number of monthly drills and an extended summer camp. Also, for the first time state Adjutant Generals had a formal relationship with the War Department. These common sense reforms were to pay their first dividends in 1916 when Ohio National Guard units were mobilized to serve as part of Gen. John Pershing’s punitive expedition against Pancho Villa along the Mexican Border. Although the expedition failed to capture or dispatch the notorious Villa and his army of bandits, valuable lessons were learned in combined operations and mobile warfare. The relatively speedy and seamless mobilization and deployment to the desert regions of the southwest also served as a confidence builder for the units and their active duty counterparts. The errors and problems of the 1916 mobilization also proved to be excellent teaching tools that were to pay dividends when the entire Ohio Guard was to be mobilized by President Woodrow Wilson a scant 10 months later in April 1917.
