I especially recommend the Kent Masterson Brown book. It goes into more detail on what Lee’s campaign was really about. And how he deliberately left wounded behind rather than dump any of the supplies his army had seized prior to Gettysburg.
Thanks again for the recommendation. I've been reading the book and before this thread fades I may finish it. It's sobering to read of the suffering of the wounded in the aftermath and it seems that Lee in effect had his own bummers. An equivalence between the sainted Lee and the devil Sherman? Of course the Yankee army in SC freed the enslaved while the Confederate army in PA enslaved the free.
