While Filipino revolutionary General Miguel Malvar, widely acknowledged to be the last leader of the Philippine Revolution to surrender to the Americans, actually capitulated on April 16, 1902, Papa Isio gave up his struggle very much later - on August 6, 1907. Finally cornered by government forces, Papa Isio surrendered to an American officer, Lieutenant J. S. Mohler. At first, he was sentenced to death, but the punishment was later mitigated to life imprisonment. Papa Isio died in the Old Bilibid Prison in Manila in 1911.
