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.

Respectfully,

FRANK P. BLAIR.

HONORABLE SECRETARY OF WAR:

Please have General Halleck make the proper order in this case.

A. LINCOLN.

Referred to General Halleck, chief of staff.
