The Border War, or the Border Campaign, refers to the military engagements which took place in the Mexico–United States border region of North America during the Mexican Revolution. The Bandit War in Texas was part of the Border War. From the beginning of the Mexican Revolution in 1910, the United States Army was stationed in force along the border and on several occasions fought with Mexican rebels or federals. The height of the conflict came in 1916 when revolutionary Pancho Villa attacked the American border town of Columbus, New Mexico. In response, the United States Army, under the direction of General John J. Pershing, launched an expedition into northern Mexico, to find and capture Villa. Though the operation was successful in finding and engaging the Villista rebels, and in killing Villa's two top lieutenants, the revolutionary himself escaped and the American army returned to the United States in January 1917. Conflict at the border continued however and the United States launched several more smaller operations into Mexican territory until after the American victory in the Battle of Ambos Nogales, leading to the establishment of a permanent border wall. Conflict was not only subject to Villistas and Americans; Maderistas, Carrancistas, Constitutionalistas and Germans also engaged in battle with American forces during this period.
