The raids and the propaganda, as well as white Texans' general fear, prompted authorities to send federal troops and Texas Rangers, who struggled to counter the raids. Eventually, on October 19, 1915, President Woodrow Wilson, as urged to by his staff to appease Carranza, officially recognized Carranza as the legitimate leader of Mexico. Then, Carranza used his armies to assist the Americans in capturing and imprisoning raiders, which ended the high tide of the Plan of San Diego.[1]
