Gen. James Bell's undated comments on Col. Benteen from Walter Camp's notes (Indiana Univ.), with my annotations in brackets:
...Benteen's weakness was vindictiveness, which was pronounced. He was indifferent to the minor matters of discipline [within his own H Company] and always had the poorest company in the regiment. He was not considered a good company officer, but was a first-rate fighter. It always galled Benteen to serve in such [ a] low rank as captain after having been a colonel in the [Civil] war. For this reason he never took the interest in his [company] command that might have been expected of him.
