The best case scenario is that the AoC besieged in Chattanooga surrenders to the AoT . With the surrender of the AoC Georgia is safe and the AoT can retake Union controlled territory in Tennessee.What was the best case scenario outcome for the Confederate army, post Chickamauga? Did Bragg do all that could be done, or would a more aggressive personality like Hood have been able to further shred and possibly destroy the AoC?

In defense of Bragg neither Johnston or Hood did all that much better commanding the AoT. If Longstreet would have deployed his Corps to besiege Chattanooga perhaps Longstreet's Corps would of blocked Hooker's 20k men from breaking the siege of Chattanooga.First kill Bragg, then destroy the yankee army before it reached Chattanooga. Any of the corps commanders would have been up to it.

As the Federals fell back from Chickamauga Thomas said the only thing that could save them was Bragg himself. In all fairness, Bragg had an excellent plan to destroy the Federal Army when it was separated into three separate units. This was below the actual battle site and there were sixty miles between the left yankee segment and the right. I believe there was so much disagreement and delays between his generals, unfortunately, it unraveled Braggs plan of attack.
There were a LOT of Confederate cavalry on site between Forrest and Wheeler.....almost 15,000. We are into the 'what if' game here. If they had combined to get in between Chattanooga and the Federal army keeping them from their retreat objective....but you would have to have the head general plan to fall upon them. The debate can be endless. I just wish Lee had came West as President Davis had urged him to do then return back to Virginia.
The best case would be the destruction of Rosecrans' army before it got back to Chattanooga. Granted, the complete defeat of an army in the field was a rare occurrence, but the circumstances including the Confederate superiority in cavalry might make this as good a chance as they were likely to get.
Presumably they would then advance as far as they could back into central Tennessee, while the Union scrambled to assemble forces - Hooker, Sherman, Burnside, etc., probably all under command of Grant. To avoid being engaged and defeated in detail, they would have to concentrate fairly far back, potentially giving the rebs back a lot of territory. They might not be able to resume the offensive before winter.
Meanwhile in Virginia, Lee managed to keep Meade in check through the remainder of 1863, but a key question for the 1864 campaign would be whether to send Longstreet back to the ANV.
The best chance for destroying the Union army was the one Forrest observed, where they were 'evacuating as hard as they could go' to Chattanooga.
Or maybe the election of McCellen doesn't matter so much. We can't know the outcome of a what if but we do know in fact that McCellen did state unequivocally that he would recognize Confederate Independence.So let's take the what-if to completion. If Rosecrans was largely destroyed, and Grant has to concentrate various Union commands to repel Confederate advances in the West, is it not hard to see a scenario where the South gains its independence?
1) Surely the March to the sea doesn't happen. In fact, Grant probably doesn't come East, Bragg remains in command, and the Western theater in 1864 is a real front again, versus merely a delaying of Sherman's march through GA
2) Meade stalemates against Lee
3) All of this means Lincoln has a much tougher election on his hands, and if Mac wins, Meade is stalled in VA and the Confederacy is still a threatening force in the West, maybe the Peace Democrats are successful in a negotiated peace
Were Forrest and Wheeler chomping at the bit to cut off the Federal retreat, and ultimately the fault lies w/ Bragg for not cutting them lose? Or were most Confederate commanders content with stopping the Federal advance and winning (arguably?) the greatest Confederate victory of the war to date?
