According to the KS Adjutant General’s report, private Levi H. Howard of Company K, 6th Kansas, was “killed in skirmish Nov. 8, 1862, near Cato, Kan.” There is no listing for a Charles Howard in either the AG report or the National Parks Soldiers & Sailors System, so it seems unlikely he was a soldier.
