according to the Jefferson Barrack site and i quote
six confederate prisoners of war executed by the union army to avenge the death of major james wilson (section 39 grave 4319) and a six man patrol executed by confederate guerrillas under the comand of major timothy reeves during the battle of pilot knob on oct 3, 1864 (section 20 graves 4605-4610)
i would assume with this info on their site that the men with major wilson are in J.B.
