Head Quarters, Dept. of the Ten.
Vicksburg Miss. July 27th 1863.
BRIG. GEN. L. THOMAS,
ADJ. GEN. OF THE ARMY,
I would respectfully call attention of the War Department to the case of Brig. Gen. J. M. Thayer whos rank among the Brigadiers seems to be anomilous. He was appointed Brigadier General to take rank from the 4th day of October 1862. As soon as notice of the appointment was received he vacated his commission as Col. of the 1st Nebraska Regiment of Infantry and the place was filled by the appointment of his successer. Gen. Thayer though never rejected, I believe, by the Senate was not confirmed until the 13th of March 1863, and now appears on the official list of Brigadiers to take rank from that date. The same rule does not seem to have applied to others who had been serving as Generals previous to the meeting of Congress.
Gen. Thayer has served constantly from the begining of the rebellion, I believe without a days leave of absence. He has been in command of a Brigade constantly since the summer, or Fall, of 1861 giving entire satisfaction, and received his promotion for meritorious services at Donelson and Shiloh.
It seems to me but a simple act of justice to Gen. Thayer to date his rank back to the date of his first appointment and thus restore him to the same relative rank he had before confirmation by the Senate.
I am Gen. Very respectfully
your obt. svt.
