I have not been able to locate a casualty list for this engagement. Here is some information on this affair.
Cherokees in Battle - September 13, 1862
"In 1862, when the Civil War experienced a major turning point, several companies of the Thomas Legion were ordered to Powell's Valley, which is located between Jacksboro and the Cumberland Gap. On September 13, 1862, an Indian company of the legion was ambushed by a Union reconnaissance force at Baptist Gap. (The site is near the Virginia state line and about ten miles north of Rogersville, TN.) . . . “
“ . . . The Indians, enraged at their loss, also scalped several of the Federal wounded and dead . . .”
