General Samuel Cooper
Adjutant and Inspector General
   On being so ordered I repaired at once to Montgomery and relieved General Stephen D. Lee of command of this department. ***** I took active measures to provide for repair of railroad from Montgomery to Opelika {Montgomery & West Point RR}, and to guard the approaches through North Alabama against raids on that line of road or the line from Demopolis to Montgomery {Alabama & Mississippi Rivers RR}. *****
I am, very respectfully, your obedient servant,
Dabney H. Maury
