Several members of my family were in the Confederate Army's 10th Regiment, Tennessee Cavalry, Company D (DeMoss'). My 3rd-great-grandfather Joseph Tarkington was a private in Company D, but by May-June 1863 he was home on sick leave due to asthma and pneumonia. My 3rd-great-grandfather's brother John G. Gatlin was also a private in Company D; he was captured in December 1863 and was held prisoner at Rock Island Barracks in Rock Island, Illinois. One of the regiment's colonels, William E. DeMoss, was my second cousin 6 times removed. His father, Abraham Louis DeMoss, was the son of Abraham Louis DeMoss and Hannah Greer. Hannah's sister Sarah was my 6th-great-grandmother.
The 10th Regiment, Tennessee Cavalry was organized in February 1863, by consolidating Cox's and Napier's Battalions. The men in Company D were from Davidson County, Tennessee. Some of the regiment participated in the battles of Battle of Thompson's Station, Brentwood, Chickamauga, the Atlanta Campaign, the Battle of Franklin, and the Battle of Nashville. In February 1865, the regiment was consolidated with the 11th Regiment, Tennessee Cavalry. In May 1865, they surrendered in Alabama.
