In March 1896, the United States government arrested Aguirre and Chapa because the Mexican consul accused them of conspiring to re-enter Mexico and engage in revolutionary actions, but both of the men were acquitted in federal court after the American consul's investigation concluded that they were innocent of any wrongdoing. However, the plan was signed by twenty-three people, including Aguirre, and one other man believed to be Tomas Urrea, the father of the revolutionary
Teresa Urrea. Because Tomas Urrea had close relations with many of the people involved in the uprising, Teresa Urrea was suspected of being the mastermind. Sixty to seventy Yaqui, Pima and Mexican revolutionaries, many of them employees of the
Southern Pacific Railroad, united in a rebel band calling themselves "Teresitas" to participate in a raid, with the goal being to "capture the arms, ammunition, and money in the Mexican custom-house at Nogales." Nogales, Sonora, and Nogales, Arizona are immediately opposite each other on the
U.S.–Mexico border, so on August 12, when the Teresitas attacked, the Mexican
consulate, Manuel Mascarena, requested aid from the Americans in or around the American Nogales. A militia was hastily assembled on the Arizona side of the border and sent in to help rout the rebels during the battle. On the next day
Brigadier General Frank Wheaton dispatched elements of the
24th Infantry. At least three men were killed in the fighting and several others were wounded, but other sources claim that seven Mexicans died while the Teresitas lost about the same amount. When the rebels retreated they were pursued by a
posse of Sonoran policemen. The police eventually caught up with the Teresitas later that day and fought another skirmish which left the Mexican commander dead. On the day after that, a large force of Mexican Army troops, under the command of
Colonel Emilio Kosterlitzky, joined in the pursuit while two companies of the 24th Infantry conducted their own separate operations. Both of the pursuing parties failed to catch up with the rebels, a portion of whom dispersed to their homes in southern Arizona. After that there was no further conflict, and the successful defense of Nogales was effective in suppressing the uprising. ==Aftermath==
