By the advertisements in your newspapers, calling upon masters to come forward and claim these men so captured, I suppose that your authorities still adhere to that claim--that is to say, that whenever a colored soldier of the United States is captured by you, upon whom any claim can be made by any person residing within the States now in insurrection, such soldier is not to be treated as a prisoner of war, but is to be turned over to his supposed owner or claimant, and put at such labor or service as that owner or claimant may choose, and the officers in command of such soldiers, in the language of a supposed act of the Confederate States, are to be turned over to the governors of States, upon requisitions, for the purpose of being punished by the laws of such States for acts done in war in the armies of the United States. You must be aware that there is still a proclamation by Jefferson Davis, claiming to be chief executive of the Confederate States, declaring in substance that all officers of colored troops mustered into the service of the United States were not to be treated as prisoners of war, but were to be turned over for punishment to the governors of States. I am reciting these public acts from memory, and will be pardoned for not giving the exact words, although I believe I do not vary the substance and effect. These declarations on the part of those whom you represent yet remain unrepealed, unannulled, unrevoked, and must therefore be still supposed to be authoritative. By your acceptance of our proposition, is the government of the United States to understand that these several claims, enactments, and proclaimed declarations are to be given up, set aside, revoked, and held for nought by the Confederate authorities, and that you are ready and willing to exchange, man for man, those colored soldiers of the United States, duly mustered and enrolled as such, who have heretofore been claimed as slaves by the Confederate States, as well as white soldiers? If this be so, and you are so willing to exchange these colored men claimed as slaves, and you will so officially inform the government of the United States, then, as I am instructed, a principal difficulty in effecting exchanges will be removed.
