The Col. John and Carrie McGavock home – Carnton – was situated less than one mile from the epicenter of the action that took place on the Union Eastern flank at Franklin. Because of close proximity geographically, and the compassion of Carrie McGavock, hundreds of Confederate soldiers were tended and cared for immediately after the battle at Carnton. As many as 300 soldiers found care inside the home and possibly hundreds spread out on the plantation grounds. Confederate surgeons worked tirelessly to save as many boys as possible.
