The thing is during his lifetime the general didn't want the fame the Lost Cause folks have heaped on him.
In my area Lee is celebrated because of his honor via his choice to defend Virginia, and for his adherence to the idea that state and local is more important than Federal.
My region of NC (Avery, Ashe, Watauga, Alleghany counties) was originally vastly against secession. On the issue of secession, my county voted 84% to stay in the Union and NOT secede. Hardly anyone owned slaves in the county. Hence why I have a picture of Lincoln next to Lee and Stonewall in my house.
My county only voted for Secession reluctantly after Fort Sumter and to satisfy the Christian honor code of defending your neighbor. It really exemplifies the reality of the "Lost Cause". The "Lost Cause" is reality for many counties in the mountains. County residents did not have slaves and hated the Southern plantation owners agitating for secession as much as Northern businessmen at the time.
From our state rep at the time:
“The present unhappy condition of the country is but the result of the programme laid down by the disunionists at Charleston, in the [Democratic] National Convention held there last spring. . .Conceiving that some better excuse for disunion than any which had yet arisen must be made before they could hope to arouse the passions of the Southern people and bind them to their policy, they set to work to bring that excuse into existence.”
One would expect Crumpler, who was one of the most public proponents of the Union, to resist service in the Confederate Army. However, Crumpler’s true allegiance was to North Carolina, and he was willing to follow his state wherever it led. He wrote that
“I yield to no man in devotion to the rights and honor of my State. If the evil must come, if wise and moderate counsels are not to prevail, if the bosom of my country must be bared to the ploughshare of civil war, I pledge myself to gentlemen here and now, when the drum shall beat and the bugle shall sound, and when the roar of the cannon shall mark that Carnage has sat down to his feast,
we will be found as far advanced against the broken ranks of North Carolina foes as the most fiery spirit among [the secessionists].”
