Frank Varney and I played on the same Little League team. I have read his first book and will be reading his second when it is published; I was at a lecture he gave in our old hometown library a few years back. It was interesting and he has done a lot of research I was glad to see, but I don't think he and I agree 100% on Grant and Rosecrans. He's moved back to New York now, maybe 200 miles apart, so maybe I'll run into him again one of these days.More recently Frank Varney has dissected Grant's Memoirs in relation to Rosecrans and others and comes to a conclusion even harsher than Conger's. Varney has been attacked by a small group of Grant partisans on this site. He is a Cornell PhD and a college professor something his critics on this site aren't.
On Rosecrans and Grant: I have been a Rosecrans' fan ever since I read William Lamers' The Edge of Glory 40+ years ago. Rosecrans had some brilliant moments and some bad ones. He played a big part in creating some of his own problems. Grant had his own problems -- but there is no general in the Civil War with a better record of success than Ulysses S. Grant.
