Jáudenes was in Manila when the Spanish parliament, the Cortes, learned of Governor-General Basilio Augustín's attempt to negotiate the surrender of the army to Filipinos under Emilio Aguinaldo.[1] This caused Augustin's removal on July 24, 1898, and the appointment of Jáudenes.[1] By Royal Decree of October 5, 1898, Jaúdenes was removed from all his positions and after his return to Madrid, tried in the Supreme Council of War and Navy for his surrender of the Plaza de Manila.
