True. The German population was especially loyal to the union, and this made them unpopular with Confederate sympathizers. But for the Germans, Missouri might well have seceded.
Southern Missouri is a far better place for Confederate monuments.
There were a lot of Confederate supporters in the boot heel of southeast Missouri. But even more further north and west along the Missouri. You might think it was too far north for slavery, but it wasn't. It also had a lot to do with where people had come from.
Harry Truman's family in northeastern Missouri were Confederate sympathizers. Jesse James came from nearby and carried out his private war even after Appomattox.
I should have said “northwestern Missouri.” But it’s that counterintuitive that there should have been secessionist sentiment that far from Dixie.
