He was not a fan of slavery even on a personal level - he had a lot of headaches with the ones at Arlington. But, he was stuck with them.
Yes he did have problems with them. He tried to hire an overseer but couldn’t find one that he liked so was forced by circumstance to manage them personally. He was so ham-fisted that he encouraged several to run away - a situation that caused him a bit of embarrassment and expense to drag them back and properly punish.
I have always held those Great Men on both sides in the highest regard. It is a tragic and epic story. I remember reading that Lee never saw the Lee Mansion again, except for a brief moment while passing it aboard a train. Of course all too many of the Union soldiers who died at the hands of Lee’s Army were then buried in his front yard. (His horse was “Traveler”?) I would have loved to have fought for almost any of them, North or South (except for maybe McClellan). Fifty years ago, my father told me that Stonewall Jackson liked to suck on lemons. Shame on us if we can’t get to 1,000 posts.
