Really enjoy that this timeline has the entirety of the cultural South within the Confederacy's borders rather than just the eleven states, it makes for a more interesting story. I imagine the hard-hitting Orphan Brigade of Kentucky are men of absolute legend within the South, a romantic tale of the begotten and true hearted Southern American sons of the Bluegrass who expelled the Tories from the Pennyroyal hills of the tobacco-laden Dark and Bloody Ground in the warrior spirit of their Scots-Irish Border Reiver ancestors, rallying thousands more Kentuckians under the banner of reaction alongside the infamous and brooding Hangman, Stonewall Jackson himself.
The stars and bars raised over Louisville, "My orphans---my poor orphans; revenged at last!" Dark and tragic for the human suffering and extension of slavery their victory entails? To be sure. But romantic nonetheless. I imagine that there might have been quite a few more Kentucky Confederate regiment and even maybe an extra brigade or two in this timeline but those initial few in the Orphan Brigade would likely dominate Kentucky politics well into the future due to their fame. Kentucky Confederates had this song that captures the feeling very well, I imagine the updated 1865 lyrics would be very boastful.
The story will only grow more interesting when those East Kentucky hillbilly Tories and their western Virginian and eastern Tennessean kin, already probably resentful of the planter elite in Lexington, Nashville and Richmond, get put through the ringer with coal and lumber extraction giving them an even greater reason to hate the elites. The closest example we have to Kentucky-Tennessee-Virginia Appalachians reacting to something approximating "slave labor" being used in the mines is the 1891-92 Coal Creek War in which the coal companies tried using convict leasing in the mines, only for the miners to set the convicts free and wage war on the company, it ultimately ended in the end of convict leasing in that particular part of the nation. "Pierpont and the men at Wheeling are gone, but they were right about these lowlanders all along," many a miner's lip may say as socialist propaganda filters down through the mountains.
