According to the book "Southern Boots and Saddles the 15th Confederate Cavalry C.S.A" by Arthur E. Green (Heritage Books)there was a Archibald Cameron, Pvt. Co. D who enlisted on May 1, 1862, at Pensacola, Fla. He appears on a September 12, 1863, company muster roll on extra duty as a guide by order of Gen. Clanton. There is also information on Daniel Cameron in the book. I do not know anything about a Camp Tatnall.
