When we reached Petersburg my column was halted, and instructions given me to march the cavalry and the Sixth Corps to Greensboro’, North Carolina, for the purpose of aiding General Sherman (the surrender of General Johnston having not yet been effected), so I made the necessary preparations and moved on the 24th of April, arriving at South Boston, on the Dan River, the 28th, the Sixth Corps having reached Danville meanwhile.  At South Boston I received a despatch from General Halleck, who immediately after Lee’s surrender had been assigned to command at Richmond, informing me that General Johnston had been brought to terms.  The necessity for going farther south being thus obviated we retraced our steps to Petersburg, from which place I proceeded by steamer to Washington, leaving, the cavalry to be marched thither by easy stages.

The day after my arrival in Washington an important order was sent me, accompanied by the following letter of instructions, transferring me to a new field of operations: 

“Headquarters armies of the united states.  “Washington, D. C., May 17, 1865.

“General:  Under the orders relieving you from the command of the Middle Military Division and assigning you to command west of the Mississippi, you will proceed without delay to the West to arrange all preliminaries for your new field of duties.

“Your duty is to restore Texas, and that part of Louisiana held by the enemy, to the Union in the shortest practicable time, in a way most effectual for securing permanent peace.

“To do this, you will be given all the troops that can be spared by Major-General Canby, probably twenty-five thousand men of all arms; the troops with Major-General J. J. Reynolds, in Arkansas, say twelve thousand, Reynolds to command; the Fourth Army Corps, now at Nashville, Tennessee, awaiting orders; and the Twenty-Fifth Army Corps, now at City Point, Virginia, ready to embark.

“I do not wish to trammel you with instructions; I will state, however, that if Smith holds out, without even an ostensible government to receive orders from or to report to, he and his men are not entitled to the considerations due to an acknowledged belligerent.  Theirs are the conditions of outlaws, making war against the only Government having an existence over the territory where war is now being waged.

“You may notify the rebel commander west of the Mississippi—­holding intercourse with him in person, or through such officers of the rank of major-general as you may select—­that he will be allowed to surrender all his forces on the same terms as were accorded to Lee and Johnston.  If he accedes, proceed to garrison the Red River as high up as Shreveport, the seaboard at Galveston, Malagorda Bay, Corpus Christi, and mouth of the Rio Grande.

“Place a strong force on the Rio Grande, holding it at least to a point opposite Camargo, and above that if supplies can be procured.
