Certainly Thomas of Virginia and was a great commander.
To the extent that the armies of the insurrection were effective it was because they used American soldiers, American arms stolen from the United States, American tactics, with officers trained at the US military academy who violated their oaths of loyalty to the US. When Grant took Vickburg, he told his men to trade their Enfield rifles, imported from England for the superior Springfield muskets that the Confederates used. Of 300 major battles, West Point officers commanded one side in 5, and in the other 295, West Point officers commanded both sides.
The insurrection nearly immediately lost Tennessee, the source of most of the pork in their domestic trade, and a vital source of protein. Without that, the southern cause was doomed as their soldiers weakened from malnutrition.
In response to the loss of Tennessee, Davis directed that domestic fowl production be increased. It was, but that provided food for Union Armies to live off the countryside, permitting the campaigns against Vicksburg, and Georgia. Without the vulnerability of Union supply trains, Union Armies could penetrate the south at will, and did.
Hood was probably the worst general on both sides. He managed to destroy his army and to burn Atlanta, but Bragg, who lost a very strong position at Chattanoga while he kept a major reenforcement out of the action, probably gives him some competition.
Seems like a pretty good plan. When do we start?
