Ewell advised emancipation in 1861, Cleburne in late 1863 and early 1864, Lee in 1865.
The CSA government said nope, nope, and well maybe. By the time they got to well maybe, it was way way too late. If emancipation would have given them independence like Ewell clearly said, like Cleburne strong proposed and like Lee fully recommended, and all were told no, then the CSA politician-policy makers chose wrong.. they chose no emancipation as a policy until too late.... and lost independence as a result..
Or perhaps Ewell was wrong, Cleburne was wrong, and Lee also... and the politicians were right...
Which do you say had it right all along? The generals in the field who asked for policy changes or the desk jockey politicians who refused to make those recommended changes?
