DarthShizNit, I do not doubt Forrest would have risen to the challenge of Army command.
I think he would have known and understood he needed professional staff to run his supply and logistics, having spent the war disrupting Northern plans of conquest. I think he would not have been as foolish as Hood to march North, leaving an army to ravage his country. He was impetuous, but he was a Cavalryman who understood how to beat his foe. He attacked and he kept the momentum( he called it the skeer) going. His enemy never had the chance to know what hit them or how to react.
He would have had to contend with subordinates who thought they were better qualified and they may have purposely misunderstood orders or tried to sabotage his plans, but the common man in the ranks knew he was a winner and could get results.
Like Grant, whose skills were recognised by Lincoln, Forrest would have got the results.
Atlanta was the key that won the 64 election and if in command in early 64, I do not think Forrest would have given Sherman the key.
But was all lost after Bragg’s fine army lost Missionary Ridge?
If you can laugh at the South’s stupidity at not recognising Forrest, what do you think of Jeff Davis’ retaining his friend Bragg?
Forrest could have bought the South time and time is all it needed to bring independence.
