After practicing medicine for almost forty years, it is not uncommon for a person to have had a stroke, and loose their "speech center" only to speak out on their death bed. Thus it is indeed plausible for Lee to have spoken before he passed over. With Jackson, his wish was to "die on the Sabbath" and when he was told that he would pass before the day's end he replied "It is good that it is so." When they dropped Jackson from the liter that he was on after he was shot, he actually fell on to his right side and on to a tree stump/root and the thoughts were that he injured his liver. The amputation was a success, but, with the injured liver came peritonitis and pneumonia. He was no doubt conscious until the very end, and slipped into a confused state but could still articulate. A.P. Hill was a fascinating character, who appeared at Sharpsburg to assist Jackson on the field, then to help Lee retreat. Again at Chancellorsville, Fredericksburg and Gettysburg he played major roles which Lee and Jackson would have related to and appreciated. Perhaps, in the end, whatever words were penned into the legends helped folks heal and move on. As such, no harm done, and they are mere testimony to the love and respect held for both men.
