Leading up to the Battle of Fort Henry, Tennessee on February 6, 1862, three small cavalry companies were left on the Kentucky side of the Tennessee River to delay Union troops from using Fort Heiman as an artillery platform for bombarding the fort. I understand that members of Padgett's Spy Company were a bunch of local Kentucky farmers. What information is available on the Alabama defenders of Fort Heiman, Capt. William Houston's Independent Company and Capt. David C. Hubbard's Company of Alabama Rangers?
