The thing about having the military on the border that most don't understand, is that, an area along the border will be put under Martial Law. I don't beg for the area where anyone else lives to be under martial law, why does everyone want the area I live in to be under martial law.
On March 15th President Wilson ordered Brigadier General John J. (Black Jack) Pershing to cross the Mexican border in pursuit of Villa. A brash young lieutenant by the name of George S. Patton managed to get appointed to Pershings staff just before he jumped off. Most of the regular Cavalry units in the Western U.S., including the "Buffalo Solders" of the 10th Cavalry, participated in pursuit of Poncho Villa. On May 6th another band of Mexicans raided the town of Glen Springs, Texas, shouting "Viva Villa" and "Viva Carranza." To augment the defense of the Southern borders of the United States, Wilson began a call up of the National Guard beginning with Texas and Arizona and New Mexico units on June 18, 1916. Eventually the entire National Guard participated. The role of the National Guard troops was to patrol the border, secure towns and bridges thus freeing up the regular army troops for action under Pershing.
