MAJ. GEN. H. W. HALLECK,
WASHINGTON D. C.
I have just received a private letter from Mr. Washburn 1 in which he speaks of a conversation that he had with you in which you said that anything I would recommend with referance to my Staff you would aid me in.
My individual labors have been harder probably than that of any other Gen. officer in the Army except probably yours and McClellen, with the exception of the time you was present with the Army in the Field. Much of this was due to having an entire Staff of inexperienced men in Military matters.
I now have for Chief of each the Q. M. and C. S. Departments men that are all I want. Also Engineers, Topographical Engineers and Ordnance officers in whom I have great confidance.
Of my individual Staff there are but two men who I regard as absolutely indispensable. One of them is Lt. Col. Rawlins, A. A. Gen. and Capt Bowers A. D. C. and now recommended for the position of Judge Advocate with the rank of Major.
Col. Rawlins I regard as the ablest and most reliable man in his Dept. of the Volunteer service, and with but few equals in the regular Army. Capt. Bowers has been with me for fourteen months, first a private soldier and clerk in the Office. On his promotion I made him A. D. C. and he has continued in reality an Acting A. A. Gen. He is capable, attentive and indispensable to me.
