The Confederate Army of Tennessee marched across over open ground for over a mile before they finally reached the Federal line near downtown Franklin. A soldier in the 104th Ohio wrote about that scene. Hess writes about this kind of troop assault movement then quotes the Ohio soldier:

When the terrain and vegetation allowed the troops to fire at longer ranges, they could maximize the damage done to attacking forces. At the battle of Franklin, Confederate division advanced over open, rolling ground for a mile before they attacked heavy fortifications. The Federals were ready for them and opened fire as soon as they could. Andrew Moon of the 104th Ohio scampered over the battlefield that night before his regiment pulled out of the works.

“Well, for 400 yards in front, I could hardly step without stepping on dead and wounded men. The ground was in a perfect slop and mud with blood and, oh, such cries that would come up from the wounded was awful.”
