Those who know me know I'm usually pretty hard on short biographies, since they generally require little from the author other than a brief synthesis of longer books by earlier, more thorough researchers. The only way a short bio can really stand out is if it is notable for some other feature of its writing.
As a biography of Robert E. Lee, this book is probably bound to disappoint, particularly if the reader is hoping to come off with any major insights about Lee's generalship in the Civil War (you know, the man's main claim to fame, outside of his generally successful postbellum stint as a college president). As a lengthy essay with an unusual perspective, though, it's a very interesting read. Even the list of cited sources and references contains a lot that's off the beaten path--a lot more literature, for one! Anyone who has grown up with Wait Wait, Don't Tell Me is probably familiar with Roy Blount Jr.'s oddball contributions to the NPR quiz show; the man has never met a tangent he didn't want to pursue. His natural proclivities are out in full force here, but the result is a rather different Lee portrait than one is likely to get from the more irritating partisans of either the North or the South. Sometimes the tangents can get too, well, tangential, but overall, the focus on Lee the man and Lee the myth, rather than Lee the hero/villain, is a bit of a welcome change from the heavier biographical works. There are a million books about Gettysburg, but I can't think of any that stop to address any major military figure's sense of humor. (Blame Blount's way with words, but I laughed out loud, multiple times. How often can one say that about a Civil War book? Well, one that doesn't involve General McClellan, anyway...) I wouldn't advise it as a book to read to learn anything about the military or historical side of the Civil War, but for a brief peek behind the curtain into the foibles, flaws, fussiness, and finesse of one of the war's major players off of the battlefield, it's worth a look.
