The false Japanese approval combined with the numerous frustrations of the Sakdalistas, and a popular uprising was planned. Late on May 1, 1935, Sakdalista activists spread the word that the endeavor to achieve independence would begin within twenty-four hours. Hesitant party members were told that, in the event of retaliatory American military action, Japan would intervene with support on the side of the Sakdalistas. Additionally, many were told that the police and constabularymen had become sympathetic to the Sakdalista cause, and would assist in the uprising by throwing down their weapons.
