George Harvey Thompson.
Rosters and records are not present from year to year but here is what I found.
Livingston, Gary. Cradled in Glory: Georgia Military Institute, 1851-1865. New York: Caisson Press, 1997.
Georgia Military Institute, opened in 1853.
Roster of Cadets 1853. Sophomore Class. G. Harvey Thompson, from Atlanta, Georgia. Rank Ordered 23 of a total of 31 cadets. Twenty-eight are rank ordered and three are at the end of the roster not rank ordered.
I hope this helps.
Respectfully,
