To obtain this necessary coöperation the leaders announced the inflexible principle that every native residing within the limits of the archipelago owed active individual allegiance to the insurgent cause. This was enforced by severe penalties, including burial alive, which were systematically exacted. There was little resistance on the part of the victims, who accepted the new policy with a curious combination of loyalty, apathy, ignorance and timidity. In this way there arose a strange system of dual government, in many cases the town officials openly serving the Americans while they were secretly aiding the insurrection, and with apparently equal solicitude for both. Each town was the base for the neighbouring guerillas, and when a band was too hard pressed it would dissolve and take refuge in its own community. This was easy enough to accomplish, with the aid of the people, for it took very little to transform a Filipino soldier into a good imitation of a peaceful native. Several months before the formal declaration of guerilla warfare in November of 1899, the Filipino commanders had adopted a policy of occupying a succession of strong defensive positions and forcing our army to a never ending repetition of tactical deployments. This they did with such skill that they were for a time successful. The native force would hover within easy distance of the American camps, but would avoid close conflict and temporarily disband. This would not be regarded by them as a calamity, but simply as a change from one form of action to another, and even a positive advantage. By February of 1900, General Bates had succeeded in scattering the larger bodies in the south of Luzon, and while some of the Filipino leaders and their followers abandoned the cause, which they saw was hopeless, others returned to the life of bandits, which in many cases had probably been their profession before the war. When their guns were gone they took up the knife and the torch. They did not cease to call themselves soldiers of the republic, but they were not in reality. By September General MacArthur, who had succeeded General Otis in command of the American forces in the Islands, realized that the opposition to American control came from the towns, and that the guerilla bands could not exist without their support. At first he thought that on account of the efficiency of his troops, the natives would be actuated both by conviction and self-interest to support him. But four months later he saw that further pressure was needed to secure this. So he ordered that all persons suspected of contraband traffic with insurgent organizations should be arrested and sent to Manila. In January, 1901, he ordered the deportation to Guam of twenty-six Filipino leaders, sympathizers, and agents, who were to remain there until peace had been formally declared. Two months later, Aguinaldo was captured by the dare-devil Funston of "the Suicide Squad."
