If you want Chivington on the list, that is fine by me.
My list were men that made Major General in the U.S. Army.
Chivington was a Colonel.
Chivington deserves your admiration under your previously announced criteria: “they won by the complete and utter destruction of their enemies.”
As does Lt. William Calley.
But if you want to add new criteria, as an after-thought, to exclude Chivington for some reason I can't stop you.
