You will do me a great favor by giving the order assigning me to the command of the Seventeenth Army Corps immediately, as I desire to leave Washington the next Saturday to join the command. I also request the assignment of Captain Andrew J. Alexander, of Third Regiment United States Cavalry, as adjutant-general of the Seventeenth Corps, with the rank of lieutenant-colonel. The present adjutant, or rather the former adjutant, Colonel Clark, has, I understand, been retained by General McPherson as adjutant-general of the department, and the place of adjutant-general of the corps is necessarily vacant.
I also request the appointment of George A. Maguire, formerly captain Thirty-first Missouri Volunteer Infantry, as major and aid-de-camp, and Lieutenant Logan Tompkins, Twenty-first Missouri Volunteer Infantry, as captain and aid-de-camp on my staff.
Please have General Halleck make the proper order in this case.
Referred to General Halleck, chief of staff.
MY DEAR SIR: According to our understanding with Major-General Frank P. Blair at the time he took his seat in Congress last winter, he now asks to withdraw his resignation as major-general, then tendered, and be sent to the field. Let this be done. Let the order sending him be such as shown me to-day by the Adjutant-General, only dropping from it the names of Maguire and Tompkins.
I respectfully request to withdraw my resignation as major-general of the United States Volunteers, tendered on the 12th day of January, 1864.
I. Major-General F.P. Blair, jr., is assigned to the command of the Seventeenth Army Corps.
II. Captain Andrew J. Alexander, Third Regiment United States Cavalry, is assigned as assistant adjutant-general of the Seventeenth Army Corps, with the rank of lieutenant-colonel, under the tenth section of the act approved July 17, 1862.
By order of the President of the United States:
The foregoing constitutes all sought by the resolution so far as is remembered or has been found upon diligent search.
In compliance with the request contained in a resolution of the Senate dated April 30, 1864, I herewith transmit to your honorable body a copy of the opinion by the Attorney-General on the rights of colored persons in the Army or volunteer service of the United States, together with the accompanying papers.
