LIEUTENANT-GENERAL GRANT, City Point, Va.:

A messenger is coming to you on the business contained in your despatch. Detain the gentlemen in comfortable quarters until he arrives, and then act upon the message he brings as far as applicable, it having been made up to pass through General Ord's hands, and when the gentlemen were supposed to be beyond our lines.

A. LINCOLN.

When Major Eckert departed, he bore with him a letter of the Secretary of War to General Grant, as follows, to wit:

WAR DEPARTMENT, WASHINGTON, D. C., January 30, 1865.

LIEUTENANT-GENERAL GRANT, Commanding, etc.

GENERAL:—The President desires that you will please procure for the bearer, Major Thomas T. Eckert, an interview with Messrs. Stephens, Hunter, and Campbell, and if on his return to you he requests it pass them through our lines to Fortress Monroe by such route and under such military precautions as you may deem prudent, giving them protection and comfortable quarters while there, and that you let none of this have any effect upon your movements or plans.

By order of the President: EDWIN M. STANTON, Secretary of War.

Supposing the proper point to be then reached, I dispatched the Secretary of State with the following instructions, Major Eckert, however, going ahead of him:

EXECUTIVE MANSION, WASHINGTON, January 31, 1865.
