According to both the 1870, 1860 and 1850 census reports, this man was born about 1834 and lived in Winston County. He was enrolled at Blountsville AL on Dec. 11, 1862, and sent to Camp of Instruction at Talladega AL. Calvert did not return to duty after being released among other sick and wounded from Vicksburg in Mobile Bay, July 22, 1863.
Most men processed through any camp of instruction were conscripts. Camps were established for that reason.
