If Lee had accepted the offer to command the northern army, what exactly would he have been protecting the northern states from?
HEH HEH HEH!
Brilliant.
And if Lee had won, what is it exactly he would have accomplished?
It’s funny, if he had, and led the North to victory, he’d have also likely ended up as President instead of Grant. He’d have also become the most reviled individual in the South, bar none. He knew what he was giving up by going with his state, and what he was gaining.
Richmond has become too defiled and debauched today to have it graced with his presence.
