No, the Yankees in Missouri were the descent into hell for those of the southern persuasion.
Here you go, try this. There are only approximately 75,000 pages of the official reports from the US war department for the War of the Rebellion. Every campaign, battle & skirmish has contemporaneous after action reports from commanders and officers down to second lieutenants, from both the Union and confederate perspectives for the same events.
All 75 volumes are down loadable, this is the gold standard for the history of the civil war. I have been wading through these for sometime now, and still have a long ways to go.

If you are referring to the Pro-Union Missourians that is one thing, but Yankees are from New England, Yankee was a dutch term for the English in New York (from John Cheese, or Jan Kees). I can't fathom who you are referring to Grant? Sherman? Both of whom I believe were from the Midwest. Being a border state there was plenty of opposition and support for the Union to go around.
