And this brings me to the consideration of another general subject, which Mr. Lord adverted to, and upon which he cited the authority of Vattel--that it would be monstrous, and would expose this Government to the execration of the world, if the criminal laws against murder and robbery on land, and the civil laws against trespass, were to be executed to the letter, and to the full extent of the vengeance of the law against the multitudinous enemies that are arrayed against this Government. Now, I must decline to be led out of a Court of Justice, by this argument, to considerations that appeal to the wisdom, or humanity, or policy of the Government. I would like to know whether my learned friend would contend that, if a private soldier, found in arms, and part of a military force, against the Government of this country, is arrested by that Government, and is indicted, and put upon his trial for treason, which the Constitution of the United States limits to the overt act of levying war against the Government, and if, under the indictment, he pleads in bar that he was levying war against the United States of America,--that would relieve him? For that is the whole nature of the proposition put forward in a Court of Justice,--that, because there are armies, there is no treason! Why, if your honors please, how absurd to present for the recognition of a Government, in its Courts of Judicature, the proposition that there is no treason, from the number of the confederates in the treachery! Your honors see at once that, the idea of setting up such a defence, on a trial for treason, against a private soldier, found in arms against the Government, is absurd. And yet, your honors recognize what is laid down by the publicists, that when the dimensions of a rebellion have been aggravated into the proportions of flagrant war, for a Government to insist upon the decimation or extermination of the population by the gallows or the axe, would be inconsistent with those general principles of humanity and justice that actuate, by necessity, the affairs of men.
