The 35th Tennessee were n Cleburne's Division at the time of Ringgold Gap (late Nov., 1863). If this unit is using as a guide the picture of the alleged 35th Tennessee Hardee flag from Perryville please know there is also no historical basis for that flag. It is pure fantasy!
The units at Ringgold Gap in Cleburne's Division are as follows:
6th/10th Texas Infantry/15th Texas Cavalry
17th/18th/24th/25th Texas Cavalry
7th Texas Infantry
15th Mississippi Battalion
Sadly, only one or two of the above flags from this time fram still exist.
