This occasional paper is a concise overview of the history of the US Army's involvement along the Mexican border and offers a fundamental understanding of problems associated with such a mission. Furthermore, it demonstrates how the historic themes addressed disapproving public reaction, Mexican governmental instability, and insufficient US military personnel to effectively secure the expansive boundary are still prevalent today.

This book recounts an unique chapter in the National Guard's efforts to keep America's borders secure. Starting in June 2006 and lasting until July 2008, Operation Jump Start exhibited unprecedented cooperation and teamwork among federal agencies engaged in protecting the homeland. The U.S. Customs and Border Protection, the U.S. Border Patrol and the National Guard created a cooperative, operational environment that will endure as an example on how to do things right. Based in Arizona, California, New Mexico and Texas, the Operation's mission was not to close the nation's border with Mexico but to make it more secure for legal immigration and commerce. By the time Operation Jump start ended, criminal activities of all types had declined along the border, and physical improvements made by Guard engineers along the border seemed certain to reduce illegal activities for the forseeable future.

On June 18, 1916, President Woodrow Wilson called up virtually the entire army National Guard, some 150,000 men, to meet an armed threat to the United States: border raids covertly sponsored by a Mexican government in the throes of revolution. The Great Call-Up tells for the first time the complete story of this unprecedented deployment and its significance in the history of the National Guard, World War I, and U.S.-Mexico relations. Often confused with the regular-army operation against Pancho Villa and overshadowed by the U.S. entry into World War I, the great call-up is finally given due treatment here by two premier authorities on the history of the Southwest border. Marshaling evidence drawn from newspapers, state archives, reports to Congress, and War Department documents, Charles H. Harris III and Louis R. Sadler trace the call-up’s state-based deployment from San Antonio and Corpus Christi, along the Texas and Arizona borders, to California. Along the way, they tell the story of this mass mobilization by examining each unit as it was called up by state, considering its composition, missions, and internal politics. Through this period of intensive training, the Guard became a truly cohesive national, then international, force. Some units would even go directly from U.S. border service to the battlefields of World War I France, remaining overseas until 1919. Balancing sweeping change over time with a keen eye for detail, The Great Call-Up unveils a little-known yet vital chapter in American military history.
