I did not know much about this battle so Flyer has prompted me to learn (again).
The battle for Chattanooga was the turning point in the Civil War because it opened the doorway to the Union forces for invasion into the deep South at the last moment for making possible the capture of Atlanta in time to influence the 1864 congressional and presidential elections.
There seemed to be a lot of internal struggles for power during this battle.
Thanks so much for this great series. You are doing a good thing by making them available for others to discover and learn about our history. Again thanks for the whole series!
