Best I can find is here: https://tngenweb.org/civilwar/4th-tennessee-volunteer-infantry-regiment/

On September 9, 1863, under Major Patterson, [the 4th Tennessee Volunteer Infantry Regiment] left Nashville for McMinnville, where it arrived September 15, 1863. Here it was surrounded and captured on October 3, 1863, by Confederate forces under Major General Joseph Wheeler. Major Patterson reported that his total force consisted of 270 men plus 50 convalescents who had been armed, and that he had lost seven killed, 31 wounded and missing in the fighting prior to the surrender. The men were paroled and started towards Sparta, Tennessee, whence most of them went on to their homes in East Tennessee.

Not much to go on, don’t see sources either.
