The National Archives, Washington, D. C., in Record Group 109, holds a register of patients, June 14, 1864 - March 11, 1865 (ch. VI, vol. 274) for St. Mary's Hospital (West Point, Miss.)
This hospital was originally located at Dalton, Ga., moved to La Grange in 1863, and in 1864 was located successively at Union Springs, Ala. (Aug. 17), Meridian, Miss. (Nov. 5), and West Point, Miss. (Dec. 4)
My experience is that these type records are found in large bound books, and difficult to review. Time consuming!
