I'd love to check that bend in the river, when I went to those emplacements and trenches as a kid that artillery setup the Rebs had would just shatter anything coming up that river (and they did) but overland troops were not what Simon Bolivar Buckner(Buckner had point in Bowling Green) (or was it A. S. Johnston dunno) was expecting. Major weakness of Fort Donaldson, it was not set up for ground troops but for river protection. Mouth of the Harpeth at the Cumberland there was supposed to be another artillery battery.
