The Ojo de Agua Raid was the last notable military engagement between Mexican Sediciosos and the United States Army. It took place at Ojo de Agua, Texas. As part of the Plan of San Diego, the rebels launched a raid across the Rio Grande into Texas on October 21, 1915 aimed at harassing the American outposts along the Mexican border and disrupting the local economy. After moving across the border, the Sediciosos began an assault against the United States Army Signal Corps station at Ojo de Agua. The small group of American defenders was cornered into a single building and suffered heavy casualties before reinforcements arrived driving the Seditionist force back into Mexico. The raid proved to be the tipping point in the American conflict with the Sediciosos, as its severity convinced American officials to send large numbers of American troops to the area in order to deter any further serious border raids by the Mexican force.
