Confederate Brigadier General Lloyd Tilghman learned of the impending Union operations against the Tennessee River forts he commanded, and was acutely aware of his inability to hold off such an attack. Consequently, he abandoned his weakest fortification, Fort Heiman in Calloway County, Kentucky, and concentrated his forces at Fort Henry, Tennessee. Fort Henry was to fall two days later after a sustained Union naval bombardment from the Tennessee River. (By John Osborne)
