Re: Letter about Gen. R. E. Lee
I believe it took Grant some 5 tries to capture Vicksburg. Vicksburg fell because of lack of supplies not by force. I seem to recall from the book about Champion Hill, sold through this site had one of Pemberton's officers followed orders chances are Grant would have also lost that battle.
Sorry to say, I cannot find the book and give names and other sources. I'll try and locate this book tomorrow.
