Samuel "Sam" Rush Watkins (June 26, 1839 - July 20, 1901) was a noted Confederate soldier during the American Civil War. He is known today for his memoir Company Aytch: Or, a Side Show of the Big Show, often heralded as one of the best primary sources about the common soldier's Civil War experience. Watkins was born on June 26, 1839 near Columbia, Maury County, Tennessee, and received his formal education at Jackson College in Columbia. He originally enlisted in the "Bigby Greys" of the 3rd Tennessee Infantry in Mount Pleasant, Tennessee, but transferred shortly thereafter to the First Tennessee Infantry, Company H (the "Maury Greys") in the spring of 1861.
