[Non-Sequitur]

I've read that General Lee was suffering from dysentery during the Battle of Gettysburg - not good in July heat. He was probably dehydrated )(which can manifest itself into heart problems).

Lee's health at Gettysburg was no better and no worse than it had been 8 weeks earlier at Chancellorsville.

Lee was also suffering from the loss of Stonewall Jackson. His order to take Cemetery Hill "if practicable" would have been interpreted a helluva lot differently by Jackson than it was by Dick Ewell.
