(CNN) -- Enduring privations of his own as a Civil War prisoner in Georgia, Cpl. Charles H. Knox was concerned about his wife and small child back home in upstate New York.
Eight days before Camp Lawton was evacuated as Union forces closed in, Knox wrote to his wife, Frances, saying she might consider selling the family cow to raise money.
Georgia Southern University Museum in Statesboro on Thursday announced the $2,100 acquisition of Knox's letter and medals from private collections. The correspondence is the only known surviving letter from Lawton prison, which was built near Millen, the university said.
In his letter, Knox expresses hope that he will be part of a prisoner exchange between Union and Confederate forces.
It was not to be. Knox, a member of the 1st Connecticut Cavalry captured by Confederate forces in May 1864 during the Wilderness Campaign in Virginia, was returned to the notorious Camp Sumter, commonly known as Andersonville.
In his letter, Knox refers to the North as "God's Land" and the South as "Cecesia," a reference to its secession from the United States. "Little Charlie" is his 4-year-old son.
Knox also kept a diary about his experiences as a prisoner. He was paroled at Andersonville on February 27, 1865, near war's end, and resumed his career as a carpenter. He died in February 1895 at age 70.
