He was a West Point graduate. Built Fort Abercrombie in what is now Abercrombie,North Dakota. Built the fort aroud 1850 to protect settlers from indians. Was a Lt. Colonel then. When the war broke out was a General and I believe he was in charge of the defenses of Washington, DC. I have a newspaper article from Fargo, North Dakota regarding him and the fort if you would like a copy let me know. What is your relationship to him?
