The only acceptable and convincing evidence of the real sentiments of either individuals or town councils should be such acts publicly performed as must inevitably commit them irrevocably to the side of Americans by arousing the animosity of the insurgent element. * * * No person should be given credit for loyalty simply because he takes the oath of allegiance, or secretly conveys to Americans worthless information and idle rumors which result in nothing. Those who publicly guide our troops to the camps of the enemy, who publicly identify insurgents, who accompany troops in operations against the enemy, who denounce and assist in arresting the secret enemies of the Government, who publicly obtain and bring reliable and valuable information to commanding officers, those in fact who publicly array themselves against the insurgents, and for Americans, should be trusted and given credit for loyalty, but no others. No person should be given credit for loyalty solely on account of having done nothing for or against us so far as known. Neutrality should not be tolerated. Every inhabitant of this brigade should be either active friend or be classed as enemy. In his Circular Order No. 5, dated Batangas, December 13, 1901, [393] General Bell announced that General Orders No. 100, Adjutant General's Office, 1863, approved and published by order of President Lincoln, for the government of the armies of the United States in the field, would thereafter be regarded as the guide of his subordinates in the conduct of the war. This order is familiar to all who have ever made any study of military law. Ordinarily, of course, a captured enemy is entitled to "the honors of war," i. e., he must be held, housed, and fed, unless exchanged, until the close of the war. But where an enemy places himself by his conduct without the pale of the laws of war, i. e., where he does not "play the game according to the rules," he may be killed on sight, like other outlaws.
