He was a man of intelligence, good character, and was trusted by the government. There was no attempt made before the Commission to impeach his character for credibility. Of course the purpose of his mission to Canada required him to gain the confidence of the men whose movements he had been sent to watch, and a knowledge of whose plans and purposes it was his duty to obtain. To do this it was necessary not only that he should conceal from them his real character and mission, but that he should be known to them as a man holding the same opinions and actuated by the same purposes as themselves. To gain fully their confidence was necessary to the success and usefulness of his mission. This he could only do by making them believe that his sentiments and purposes were in unison with their own. Of course this involved duplicity and falsehood, yet it is held to be allowable in war, because it may be made to contribute to success. A great deal of the strategy in war consists in deceiving the enemy; and if it is ever allowable by falsehood to deceive, it was certainly allowable by falsehood to deceive those who were playing false to their government to accomplish its overthrow. They were secretly concocting their schemes for the accomplishment of this purpose; and to be forearmed against them, it was necessary to be forewarned of them. This could only be done by this kind of deception, which is the same in its nature as that practiced by every spy. But spies are used by both parties to the conflict in every war. War is in its very nature atrociously wicked; and so, its ethics cannot be made to conform to the accepted morality that ought to govern peaceful life. But whilst war is wicked and ought never to be provoked, it is yet justifiable when it becomes necessary to the preservation of the life of a nation. Upon the aggressor in this case the responsibility belongs. On him the guilt falls. A defensive war is always justifiable; and so, according to the code of military ethics, everything that is necessary to its successful prosecution is also justifiable. This secret service department has always been considered one of these indispensable necessities; and it has never been regarded as a just ground of impeachment of a man's character for truthfulness and honesty that he has been found engaged in this kind of service. Indeed the very nature of the duties of this service call for a man of sterling integrity, in order that the information obtained through him may have the quality of reliability.
