"WASHINGTON, August 8, 1861. "GENERAL: The important question of the proper disposition to be made of Fugitives from Service in States in Insurrection against the Federal Government, to which you have again directed my attention in your letter of July 30, has received my most attentive consideration. "It is the desire of the President that all existing rights, in all the States, be fully respected and maintained. The War now prosecuted on the part of the Federal Government is a War for the Union, and for the preservation of all Constitutional rights of States, and the citizens of the States, in the Union. Hence, no question can arise as to Fugitives from Service within the States and Territories in which the authority of the Union is fully acknowledged. The ordinary forms of Judicial proceeding, which must be respected by Military and Civil authorities alike, will suffice for the enforcement of all legal claims. "But in States wholly or partially under Insurrectionary control, where the Laws of the United States are so far opposed and resisted that they cannot be effectually enforced, it is obvious that rights dependent on the execution of those laws must, temporarily, fail; and it is equally obvious that rights dependent on the laws of the States within which Military operations are conducted must be necessarily subordinated to the Military exigences created by the Insurrection, if not wholly forfeited by the Treasonable conduct of parties claiming them. To this general rule, rights to Services can form no exception. "The Act of Congress, approved August 6, 1861, declares that if Persons held to Service shall be employed in hostility to the United States, the right to their services shall be forfeited, and such Persons shall be discharged therefrom. It follows, of necessity, that no claim can be recognized by the Military authorities of the Union to the services of such Persons when fugitives. "A more difficult question is presented in respect to Persons escaping from the Service of Loyal masters. It is quite apparent that the laws of the State, under which only the services of such fugitives can be claimed, must needs be wholly, or almost wholly, suspended, as to remedies, by the Insurrection and the Military measures necessitated by it. And it is equally apparent that the substitution of Military for Judicial measures for the enforcement of such claims must be attended by great inconveniences, embarrassments, and injuries. "Under these circumstances it seems quite clear that the substantial rights of Loyal masters will be best protected by receiving such fugitives, as well as fugitives from Disloyal masters, into the service of the United States, and employing them under such organizations and in such occupations as circumstances may suggest or require.
