Personnel did not matter
Once the U.S. decided to fight for the land; poured billions into its military; would not end the war, the Confederacy had little chance of remaining as it originally intended. It's best chance was getting a tired North to end the war, with the Confederacy winding up with some six states in its Confederacy.
The thirteen Confederate states, represented by stars, in its battle flag, was a total illusion after the first year.
Remember by 1863, even R.E. Lee, Stonewall Jackson, Jubal Early and Jeb Stuart could not save the western Virginia counties for the Confederacy.
