Named after the “Father of the American Cavalry” or after a brilliant medical officer?

I’ve gone there probably 3-4 times, recognized it right off the rip. It was a big part of the U.S. civil war (objectively speaking, more or less the civil war was one of its biggest historical moments), and was a good representation of the technological advancement of cannon barrel rifling vs mortar (brick) forts and how those forts became obsolete.
