History & Significance

Battle of Ambos Nogales was a Indian Wars and Frontier Conflicts engagement fought in Arizona, 1918. It was a United States victory.

The Battle of Ambos Nogales (The Battle of Both Nogales), or as it is known in Mexico La batalla del 27 de agosto (The Battle of 27 August), was an engagement fought on 27 August 1918 between Mexican military and civilian militia forces and elements of U.S. Army troops of the 35th Infantry Regiment, who were reinforced by the Buffalo Soldiers of the 10th Cavalry Regiment, and commanded by Lt. Col. Frederick J. Herman. The American soldiers and militia forces were stationed in Nogales, Arizona, and the Mexican soldiers and armed Mexican militia were in Nogales, Sonora. This battle was notable for being a significant confrontation between U.S. and Mexican forces during the Border War, which took place in the context of the Mexican Revolution and the First World War.

Prior to the late 1910s, the international border between the two Nogaleses was a wide-open boulevard named International Street, but during the course of the decade the violence associated with the Mexican Revolution and growing hysteria related to World War I brought stricter U.S. control of the border. Anti-foreign sentiment grew in the border region with the publicizing of the German Empire's Zimmermann telegram in February 1917. (Some U.S. military historians of the 10th Cavalry and 25th Infantry later claimed German military advisors encouraged Mexican rebels under General Francisco "Pancho" Villa to fight against the U.S. in Nogales.) Related to the World War I anti-foreign sentiment, the shooting deaths of Mexican nationals at the border by U.S. soldiers in Nogales in early 1918 increased racial tensions in the two border towns. As a result of the 27 August battle, the U.S. and Mexico agreed to divide the two border communities with a chain-link border fence, the first of many permanent incarnations of the U.S.-Mexico border wall between the two cities along the two countries' border.

=== U.S.-Mexico relations in Ambos Nogales during the Mexican Revolution ===

The outbreak of the Mexican Revolution in 1910 against the long-time rule of President Porfirio Díaz initiated a decade-long period of high-intensity military conflict along the U.S.-Mexico border, as different political/military factions in Mexico fought for power. The access to arms and customs duties from Mexican communities along the U.S.-Mexico border made towns such as Nogales, Sonora, important strategic assets. The capture of the key border city of Ciudad Juárez in 1911 by Mexican revolutionaries led by Francisco I. Madero (and his military commanders Francisco "Pancho" Villa and Pascual Orozco) led to the downfall of President Diaz and the elevation of Madero to president. The violent aftermath of Madero's assassination during a coup in 1913 again highlighted the importance of the U.S.-Mexico border, as battles for control of Mexican Nogales between Villistas and Carrancistas (forces of Gen. Venustiano Carranza, a former Villa ally) led to American involvement because of cross-border firing into the U.S.. This took place during the Battle of Nogales (1913) and again during the Battle of Nogales (1915). The inability of the various political factions in Mexico to reach consensus on fundamental political, social and economic reforms prevented the conclusion of the Mexican Revolution until a significant time after the 1918 Battle of Ambos Nogales.
