That’s a great analysis. Did you put that together?
I lived in Missouri for seven years. I never realized that it had the highest number of engagements by Oct 1861.
It would be informative to show the data through time.
I keep a running tally of engagements, victories, casualties, etc., and post as close to the actual dates as I can.
So, peering into my crystal ball I "predict" the next Missouri engagement will come in about two weeks, near Belmont, the 19th in Missouri and a major battle, at least by early-war standards.
