Civil War historian Robert Krick—author of the really fine book on the Boy Battery (which fought at Knoxville)—weighed in on Gen. Longstreet back in 2000 at Gettysburg.
The talk is available here at C-Span. It’s long, almost 54 minutes altogether, but when you have time, Krick’s criticism of Longstreet is worth the hearing. The remarks on Knoxville begin at 35 minutes in.
