"My name is Wesley Norris; I was born a slave on the plantation of George Parke Custis; after the death of Mr. Custis, Gen. Lee, who had been made executor of the estate, assumed control of the slaves, in number about seventy; it was the general impression among the slaves of Mr. Custis that on his death they should be forever free; in fact this statement had been made to them by Mr. C. years before; at his death we were informed by Gen. Lee that by the conditions of the will we must remain slaves for five years; I remained with Gen. Lee for about seventeen months, when my sister Mary, a cousin of ours, and I determined to run away, which we did in the year 1859; we had already reached Westminster, in Maryland, on our way to the North, when we were apprehended and thrown into prison, and Gen. Lee notified of our arrest; we remained in prison fifteen days, when we were sent back to Arlington; we were immediately taken before Gen. Lee, who demanded the reason why we ran away; we frankly told him that we considered ourselves free; he then told us he would teach us a lesson we never would forget; he then ordered us to the barn, where, in his presence, we were tied firmly to posts by a Mr. Gwin, our overseer, who was ordered by Gen. Lee to strip us to the waist and give us fifty lashes each, excepting my sister, who received but twenty; we were accordingly stripped to the skin by the overseer, who, however, had sufficient humanity to decline whipping us; accordingly Dick Williams, a county constable, was called in, who gave us the number of lashes ordered; Gen. Lee, in the meantime, stood by, and frequently enjoined Williams to 'lay it on well,' an injunction which he did not fail to heed; not satisfied with simply lacerating our naked flesh, Gen. Lee then ordered the overseer to thoroughly wash our backs with brine, which was done. After this my cousin and myself were sent to Hanover." Documented here.
Now, your documentation that Mrs. Grant demanded that her husband whip her father's slaves?
...the "here" being www.templeofdemocracy.com, aka the home site of Ed Sebesta, a radical homosexual activist from Dallas who circulates conspiracy theories about GOP politicians belonging to secret "hate groups" and who seems to believe that the confederacy is the root cause of "homophobia" in America.
Put another way, Sebesta comes from the lunatic fringe of the south-hating leftist wacko movement and simply is not a credible source for a document that curiously doesn't appear elsewhere on the internet. For a time IIRC Sebesta was claiming that this letter was taken from Nolan's "Lee Considered," a vehemently critical biography of Lee that almost certainly would have included it if it were credible. Yet it is not there and now he's claiming another book, which very well could be apocryphal or non-existant. In short, non-seq, you've reached a low point in source material for even your wretched ilk. Quoting a nutcase like Sebesta is less credible that quoting Morris Dees or Pacifica Radio.
Sounds like a lot of Abolitionist CR*P! Besides, that is the ONLY testimony I have ever seen of such nonsense. There is much more documentation that Lee treated his slaves kindly. I am quite sure that whoever put out such tripe was trying to discredit Lee after the war. If you honestly believe that garbage, then I have certainly given you more respect and credit than you deserve!
