I’ve always struggled with the description of Stuart as the greatest cavalry officer ever. My reasoning is I feel his actions at Gettysburg left Lee blind and that decisions would have been significantly different otherwise.
I realize it was only one battle, but the impact is such that I can’t see him as the greatest ever.
I thought John Wayne was in “She Wore A Yellow Ribbon”.
General Sir Harry Paget Flashman wrote in his memoirs that he believed that the Sioux leader Gall was the greatest light cavalry leader in history.
I know ... I know ... Flashman is fictional, but George McDonald Fraser lays out a fair argument for it in "Flashman and the Redskins".
