In these few words of this great authority is found the very discrimination which enters into the present discussion. The war in which we are now engaged is not precisely “public,” because on one side there is no Government; nor is it “private,” because on one side there is a Government; but it is “mixed,”--that is, public on one side and private on the other. On the side of the United States, it is under authority of the Government, and therefore “public”; on the other side, it is without the sanction of any recognized Government, and therefore “private.” In other words, the Government of the United States may claim for itself all belligerent rights, while it refuses them to the other side. And Grotius, in his reasoning, sustains his definition by showing that war becomes the essential agency, where public justice ends,--that it is the justifiable mode of dealing with those who are not kept in order by judicial proceedings,--and that, as a natural consequence, where war prevails, the Municipal Law is silent. And here, with that largess of quotation which is one of his peculiarities, he adduces the weighty words of Demosthenes: “Against enemies, who cannot be coerced by our laws, it is proper and necessary to maintain armies, to send out fleets, and to pay taxes; but against our own citizens, a decree, an indictment, the state vessel are sufficient.”[15] But when citizens array themselves in multitudes, they come within the declared condition of enemies. There is so much intrinsic reason in this distinction that I am ashamed to take time upon it. And yet it has been constantly neglected in this debate. Let it be accepted, and the constitutional scruples which play such a part will be out of place. Senators seem to feel the importance of being able to treat the Rebels as “alien enemies,” on account of penalties which would then attach. The Senator from Kentucky [Mr. DAVIS], in his bill, proposes to declare them so, and the Senator from Wisconsin [Mr. DOOLITTLE] has made a similar proposition with regard to a particular class. But all this is superfluous. Rebels in arms are “enemies,” exposed to all the penalties of war, as much as if they were alien enemies. No legislation is required to make them so. They are so in fact. It only remains that they should be treated so, or, according to the Declaration of Independence, that we “hold them, as we hold the rest of mankind, _enemies in war_, in peace friends.” * * * * * Mark now the stages of the discussion. We have seen, first, that, in point of _fact_, we are in the midst of rebellion and in the midst of a war,--and, secondly, that, in point of _law_, we are at liberty to act under powers incident to either or both of these conditions, treat the people engaged against us as criminals, or as enemies, or, if we please, as both. Pardon me, if I repeat these propositions; but it is essential that they should not be forgotten.
