[1] Camp Thomas, a Regular Army training base in Columbus, Ohio, was named in his honor in July 1861.
He held the position of adjutant general until he retired in 1869, except for a special assignment to recruit African-American troops in the Military Division of the Mississippi from 1863 to 1865.
Many historians have claimed Thomas was banished in disgrace after conspiring to defame Union General William T. Sherman as insane.
[4][5] On March 8, 1866, U.S. President Andrew Johnson nominated Thomas to the grade of brevet major general in the regular army, and the U.S. Senate confirmed the appointment on July 14, 1866.
[6] On February 21, 1868, President Johnson attempted to replace Stanton by appointing Thomas as Secretary of War ad interim.
