That's a rather different Sherman. 'Our' Sherman had a conflicted history with Indian relations - he seems to have been respected by the Indian leaders for telling them plain truth, and feared for his unrelenting enforcement of reservation orders. This Sherman seems not just hard but actively vengeful - a thin line but one I think the historical Sherman did not cross. And as you note, Sherman (like just about everyone in the North) had a complicated view of slavery, African-Americans and race relations. I find this Sherman troubling.
I do think our present circumstances would be different if Reconstruction-era congresses had taken a hard line against the 'readmitted' state constitutions. But the North and the Army did take a hard line against the KKK, at least eventually. Had the KKK been permitted to keep growing at its rapid pace (in Northern states as well as Southern) we might have had an earlier encounter with a 'Jim Crow' totalitarianism on a national scale.
Quite. While I'm taking the historicity of Sherman's memoirs where he saw himself something of an instrument of judgment against the rebels, we're going for a much more conflictual Reconstruction at the moment. Plus, as a native Buckeye, and Sherman a native Buckeye, there is nothing but Ohio love to the point of romanticization with me and him!

As such, and with Sherman in control of the Union/American forces in the south, he is the instrument of Reconstruction which, at least partially, had been implemented along the lines of Radical Republican plans before coming to halt as the end of the update concludes. All the more reason now for southerners to dislike Sherman! All the more reason for me to like Sherman! Don't forget, there a few people and moments that I, volksmarschall, have planned just because of my desires. Like a long awaited WJB presidency, if we ever get there.
It's great to see and hear from you again Porter. I hope all is well! As you probably remember, my time here at Yale is winding down. If you somehow manage to be up anytime in the next month, do let me know!
But, as promised way back in the preface, I don't want to spend too much time on Reconstruction and the New South as related to Reconstruction. Gets too much time (perhaps rightfully so) in most histories and education in American history. I want to focus on populism, labor, the conflict between agrarianism and labor vs. industrialization and capitalism; what some historians call the agrarian or populist revolt and the "greatest democratic mass movement in American history." Which gets oooohhhh so little attention and is often glossed over as the prelude to the great transformation of America, the engines of progress, and the "men who made America." What rubbish!
