staff. He served in this capacity through the Atlanta campaign, and on the pursuit of Hood until Allatoona was reached, when he accepted the Colonelcy of one of the new regiments. General Sherman, upon relieving him from duty, thanked him in special orders for his zealous and intelligent service, and complimented him "on his good sense in preferring service with troops to staff-duty."

Colonel Warner joined his new regiment at Decherd, Tennessee, and in January, 1865 was ordered to North Carolina. After the capture of Fort Fisher he participated in the engagement at Kingston, and upon the occupation of the capital of the "old North State" he was made Provost-Marshal of the city. After the surrender of Johnston's army he was placed in command of the post of Charlotte, North Carolina, and he continued in that position during the remainder of his term of service. Upon the recommendation of Generals Cox and Schofield, his corps and department commanders, he was brevetted Brigadier-General in July, 1865. Shortly after this he was mustered out of service, with the additional honor of Brevet Major-General, for "gallant and meritorious conduct during the war," to rank from March 13, 1865.

In the fall of 1865 he was chosen State Senator from the Sixteenth Senatorial District, and he soon proved himself as efficient in the council as in the field. He resumed his old residence at Newark.
