That is why the Confederacy lost in Kentucky, Missouri and Tennessee. Too close to navigable streams and the superiority of Yankee steamboats, bringing troops and supplies.
"Lexington was the fourth largest city in Missouri at the time. It was a cultural center for Southern society. It was a riverboat town from the very begining of the western expansion movement."
Riverboat town ! That ended any hope to control that area, with any large Confederate force. Culture can't beat a riverboat.
As I recall Missouri Governor Jackson died in Arkansas.
"Is there any doubt that "IF" the
CSA had re-enforced the Missouri State Guard that St. Louis would've fallen and Kentucky would've sided with the South too?"
Do pigs fly too!!! I don't see any reason to duplicate the great mistakes of the Confederate leadership, who thought in 1861, that it could militarily control anything for long in Missouri and Kentucky.
I'd suggest a study of steamboats and why the Confederacy could never hold Kentucky or Missouri for long. Lexington was a riverboat town. Yankee riverboat town. Fort Henry, Fort Donelson, Island #10, Columbus, Kentucky, Louisville, Kentucky, St. Louis, Nashville,and Memphis were all on navigable streams, controlled early in the war by Union steamboats.
Missouri was too far north, and too far west for the Confederate States to supply an army and maintain one in Missouri.
The Confederacy lost Missouri because the United States was a Riverboat nation.
