The only muster roll extant for Company F, 9th Tennessee Cavalry is that for the period Nov & Dec, 1862 dated February 22, 1863, James D. Sellers, Company F was not recorded therein, we would therefore assume he enlisted sometime later, he was captured in Lauderdale County, Alabama March 26, 1864, sent to Camp Chase, Ohio prison camp arriving April 13, paroled and transferred February 12, 1865 to Point Lookout, Maryland prison camp, no further records [He was most likely forwarded thereafter to City Point, Virginia for exchange]
