Twain I recall changed the names to protect the guilty. My memeory may be a bit faulty but the supposedly represents the Hazen-Carmicheal feud and it took place in Knoxville, Tennessee. One side was prior to, during, and after the war Unionist the other sucessionist. Life in East Tennessee the majority being pro Union was hellish under CS occupation. Many were arrested, detained, imprisioned, or in the case of Parson Brownlow deported, and hanged without trial by Danville Ledbetter CS Provost. Add to the CS paranoia, incidences of bridge burning, public meetings, and all out gurellia warfare against CS Authorities the animiss built from before the wartill CS troops were totally driven out late in '64. Brownlow and others already had a Lincolnite government in place even before Lee's surrender. Post Bellum paybacks were hell. Knoxville from 1865 til about 1880 enjoyed the highest murder per capata rate in our nations history until the LA riots years in the 1990's. Higher than Deadwood,Dodge City, or Tombstone. My ggf & the 8th Tn Cav USA was under command of George Stoneman ordered to shoot on sight any East Tennessean under arms for it was assumed that the were unrepentant Rebs or bushwhackers until September 1865.
