than six months. On April 30, the U.S. Army's 5th Reinforced Brigade under Brigadier General Frederick Funston arrived and took over the occupation of the city, with Lewis serving as the Treasurer of the Military Government during the United States occupation of Veracruz. Mobilization In 1915, Lewis served as Inspector-Instructor of the Illinois National Guard in Springfield, and was the senior mustering officer for the state. The next year, he was promoted to brigadier-general to command a brigade of National Guard troops, and was deployed to Texas.
