Thayer's Note:

a As very often, space and other considerations result in brief and bland statements in Cullum's Register. Although Major Hagner was loyal to the Union, it wasn't good enough for the more rabid war faction, and his tour of duty at St. Louis was cut short by the maneuvers of Indicates a West Point graduate and gives his Class.Nathaniel Lyon (q.v.); I imagine Hagner was only too glad to get away from the infighting.
