In weather news, it's pretty much summer here, late afternoon showers are becoming common (and welcome), highs in the mid to upper 80s, it can be sunny and an hour later be pouring rain. The area around us has many historical markers, mostly about some brigade moving from here to there in 1864. I try and visualize what any of that was like back then, the weather would have been hot of course as Sherman marched south. It's an interesting campaign as Johnston tried to block Sherman and isolate on one of his corps, but never could pull it off, which suggests to me that it is very difficult to manage an army of 50,000 or so men to get them to do what you want when you want it. Sherman was able to lever Johnston from a prepared line time and time again until Kennesaw Mountain, and after that battle Sherman flanked Johnston again and forced him to fall back, always falling back, which made Jeff Davis angrier.
I don't know what would have happened of course had Johnston been left in charge, probably more falling back, as he really lacked the resources to fight Sherman's army, and could have ended up encircled in Atlanta. Maybe CWS knows. I know it must have been hot.
Sherman IMHO was one helluva general.
