Sherman's army group consisted of the Army of the Tennessee & the Army of Georgia. The list of Confederate Full Generals who opposed it is a long one. Early had neither the rank nor personal prestige to be anything but a spear carrier in the March to the Sea & Carolinas. As it was, he was not event that.
I don't really consider Bragg or Beauregard having much prestige. Bragg was dragged to Richmond after Lookout Mountain, his star had fallen. Beauregard was hated from way back by Davis and had bounced around like a rubber ball.
If you want talk prestige Hardee has done some very good things in Florida with considerably less than a lot of other comms ders in other theaters of the war. Granted, the state was largely closed off on the coast to large scale shipping. When it came to stopping union advance, Florida did an extremely good job .
That includes regular army, state troops, militia/home guard, as well as a series of independent commands that were very good in what they did. JJ Dickison and John Person. Dickison fought against regular Federal cavalry at Ocala, and managed to capture himself a ship.
Pearson managed to get men out to a federal vessel off Shell Point at Tampa during the attack of Ft Brooke, disguised a fleeing slaves. The plan to capture that ship didn't come to fruition, however it did get Pearson moved up to the farm team to big leave in Virginia. He was not well trained apparently in getting out of the way of fire, was wounded and it proved mortal.
If you really want to go there even the cow boys guarding the livestock got into the act, attacking Ft. Myers, albeit at the end of the war,band pretty much out of spite for a raid inland by the troops stationed there.
All the union had down there was Pensicola, Key West and Jacksonville. None of which do you want good at all if improperly used. And all of them launched attacks that just didn't cut it.
Blockade runners still came into places that granted were not deep water ports, but the cut off of supply that was felt in North Carolina was impossible in Florida.
The middle of the state, from the St Johns River, to the Oklawaha, to up the Silver River to the spring and up. That included troops. Though the number was small that artery was open until very near the end of the war when at sixteen shallow draft river boats were sold,their owner recovering his money put up to build them having seen the writing on the walls.
Invade Cedar Key? Kicked off. Attack Ft Booke? Fail. Olustee? Hold my beer...
The culmination of all of this Natural Bridge where union troops landed at the mouth of the St. Marks River and managed to get beat and not take Tallahassee
All this was under and later by people who had worked with Hardee. So he's looking much better to me now. They say insanity is doing the same thing over and over expecting better results. Maybe Beauregard and Bragg were a poor idea.
