These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Tear Jerker: "This boy was brought up in a time of blood and dying and never questioned a bit of it. He never turned his back on his folks or his kind. I rode with him... and I got no complaints. The blue bellies will give ya a better burial than I can, boy."
Truth in Television: The fighting in Missouri during the American Civil War really was as savage as the film implies, and in more than a few cases was used as an excuse to address old arguments and rivalries that may not have even had anything to do with the causes of the war itself. In fact some parts of the Missouri/Kansas border area still maintain bitter animosity over the war to this day.
