"Hindman's edicts however raised the ire of the local citizenry and they, and Hindman's political enemies, demanded that Richmond replace him. By August of 1862 the authorities in Richmond decided to replace him with the well-meaning but incompetent Theophilus 'Granny' Holmes." [From Wikipedia]
Hindman was reduced to simply commanding the 1st Corps in the field. Your saying that he remained in Arkansas until 1863 was true, but his martial law was rescinded by Holmes. You left that out.
Contrast what Davis did in relieving Hindman of overall control, with what Lincoln did with respect to Beast Butler. Lincoln even offered Beast the vice presidency in 1864. Fortunately for all of us, Yank and Reb alike, Beast turned it down.
Oh, I don't know. Having Ben Butler in the White House from 1865 to 1869 would have had a certain.....clarifying effect on what the war was all about.
And here's another interesting thought: would the other commands have capitulated, knowing Butler was now in charge, after Lincoln's assassination?
That's a lot to think about.
Erratum: I have occasionally posted upthread, here or elsewhere, about a Texas Confederate outfit I referred to as "Waugh's Legion": the actual name was Waul's. It was a 6,000-man combined-arms formation with organic horse, infantry, and artillery elements.
