I do not think I would tie that accomplishment too closely to the glory of the Confederacy. A large portion of the Civil War descendants of those King's Mountain patriots remained loyal to the Union during the rebellion. On the other hand, the ancestors of the South Carolina secessionists were often Tories. And that's not surprising as the Confederates were very eager to align themselves back to England and France to protect their precious slavery. This is completely false. My own ancestors were on the right side of both wars. And let us not forget that Robert E. Lee was George Washington's Kinsman.
From Melville:
He who has seen the face of Lee
has seen the face of Washington
And he must hide the though
so fraught with grievous meaning is it wrought
I was not talking about Virginians or patriots and tories in general. I was talking about the patriots at Kings Mountain, John Sevier's Overmountain Men and their opponents, the prosperous lowland South Carolina tories. The Kings Mountain patriots returned to the mountain homes and for the most part their sons and grandsons did not like domination by a rotten aristocracy any more than their fathers did, so naturally many overcame obstacles to fight and work against the new tyranny of Richmond.
Likewise, the same slavery dominated civilization that gave rise to widespread toryism would naturally embrace the ideal of new aristocracy of the "best men".
