Slaves being captured by us, and the right of property in them thereby vested in us, that right of property has been disposed of by us by manumitting them, as has already been the acknowledged right of the owner to do to his slave. The manner in which we dispose of our property while it is in our possession certainly cannot be questioned by you. Nor is the case altered if the property is not actually captured in battle, but comes either voluntarily or involuntarily from the belligerent owner into the possession of the other belligerent.
I take it no one would doubt the right of the United States to a drove of Confederate mules or a herd of Confederate cattle which should wander or rush across the Confederate lines into the lines of the United States army. So it seems to me, treating the negro as property merely, if that piece of property passes the Confederate lines, and comes into the lines of the United States, that property is as much lost to its owner in the Confederate States as would be the mule or ox, the property of the resident of the Confederate States, which should fall into our hands.
If, therefore, the privilege of international law and the laws of war used in this discussion are correctly stated, then it would seem that the deduction logically flows therefrom in natural sequence, that the Confederate States can have no claim upon the negro soldiers captured by them from the armies of the United States because of the former ownership of them by their citizens or subjects, and only claim such as result, under the laws of war, from their captor merely.
Do the Confederate authorities claim the right to reduce to a state of slavery free men, prisoners of war captured by them? This claim our fathers fought against under Bainbridge and Decatur, when set up by the Barbary Powers on the northern shore of Africa, about the year 1800,—and in 1864 their children will hardly yield it upon their own soil.
This point I will not pursue further, because I understand you to repudiate the idea that you will reduce free men to slaves because of capture in war, and that you base the claim of the Confederate authorities to re-enslave our negro soldiers, when captured by you, upon the jus postliminii, or that principle of the law of nations which inhabilitates the former owner with his property taken by an enemy when such property is recovered by the forces of his own country. Or, in other words, you claim that, by the laws of nations and of war, when property of the subjects of one belligerent power, captured by the forces of the other belligerent, is recaptured by the armies of the former owner, then such property is to be restored to its prior possessor, as if it had never been captured; and, therefore, under this principle, your authorities propose to restore to their masters the slaves which heretofore belonged to them which you may capture from us.
But this postliminary right under which you claim to act, as understood and defined by all writers on national law, is applicable simply to immovable property, and that, too, only after complete resubjugation of that portion of the country in which the property is situated, upon which this right fastens itself. By the laws and customs of war, this right has never been applied to movable property. True it is, I believe, that the Romans attempted to apply it to the case of slaves; but for two thousand years no other nation has attempted to set up this right as ground for treating slaves differently from other property.
But the Romans even refused to re-enslave men captured from opposing belligerents in a civil war, such as ours unhappily is.
Consistently, then, with any principle of the law of nations, treating slaves as property merely, it would seem to be impossible for the government of the United States to permit the negroes in their ranks to be re-enslaved when captured, or treated otherwise than as prisoners of war.
I have forborne, sir, in this discussion, to argue the question upon any other or different ground of right than those adopted by your authorities in claiming the negro as property, because I understand that your fabric of opposition to the government of the United States has the right of property in man as its corner-stone. Of course, it would not be profitable in settling a question of exchange of prisoners of war to attempt to argue the question of abandonment of the very corner-stone of their attempted political edifice. Therefore I have admitted all the considerations which should apply to the negro soldier as a man, and dealt with him upon the Confederate theory of property only.
I unite with you most cordially, sir, in desiring a speedy settlement of all these questions, in view of the great suffering endured by our prisoners in the hands of your authorities, of which you so feelingly speak. Let me ask, in view of that suffering, why you have delayed eight months to answer a proposition which by now accepting you admit to be right, just, and humane, allowing that suffering to continue so long? One cannot help thinking, even at the risk of being deemed uncharitable, that the benevolent sympathies of the Confederate authorities have been lately stirred by the depleted condition of their armies, and a desire to get into the field, to affect the present campaign, the hale, hearty, and well-fed prisoners held by the United States in exchange for the half-starved, sick, emaciated, and unserviceable soldiers of the United States now languishing in your prisons. The events of this war, if we did not know it before, have taught us that it is not the northern people alone who know how to drive sharp bargains.
