Had an interesting chat with local Civil War friends about this very subject.
Shelby Foote & Ed Bearss was the topic of conversation. Forte, as we all know, made a point of saying that he wasn't a historian. He wrote a narrative, not a scholarly history. Ed Bearss, on the other hand, was not only an implacable researcher, he also had a wife who was an excellent historian in her own right. He had a live in fact checker & editor.
One of our coffee drinkers was about to discuss Burn's Civil War documentary with students. He wanted to know what we thought about it.
Shelby Foote repeats several apocryphal stories. Grant, on a drunken bender, was not saved from ruin by a correspondent. The man was nowhere near where he claimed to be. Forrest pulling a Yankee up behind him at Shiloh is from a work of fiction. Both were written decades after the war. To this day, both are fervently believed by individuals who have personal agendas rather than historic factual rigor as their goal.
Ed Bearss, in his characteristic manner, was spot on in his statements. As someone who knew him well said, Ed was, 'a d****ned rat terrier' when it came to pursuing a source. That combined with his supernatural memory were a formidable combination. I am told that the excellent footnotes, etc. in his many books were very much a partnership with his wife, Margie Riddle.
With my own ears, I heard Foote reply to a question that, "Southern storytellers never let the facts get in the way of a good story." That does not mean that Foote did not care about the factual content of his books. However, they were very much a personal narrative, not a history. I don't know if I have ever seen a reference to Foote in a footnote. That is not what his work should be read for.
My point is that if you are going to nit pick Shelby Foote, you are woofing up the wrong tree. On the other hand, if you are entering the lists with Ed Bearss, you better tighten your straps, hitch up your boots & dig your spurs in deep.
