The four recorded Rickersville Hospital covers are from the Lt. Oliver R. McNary correspondence (three from him and one addressed to him). He was a member of Co. E of the 12th Pa. Volunteers. McNary was captured on April 20, 1864 at Plymouth N.C., taken to Andersonville where he attempted to escape, then to Macon from where he did escape on July 30. He was recaptured on August 17, injured during his flight and taken to Rickersville Hospital on August 21. The enclosed letter states, "…(brought) to this place from Macon Geo last week. At present am in the 1st South Carolina Hospital…" He was then moved to Annapolis Hospital on December 4 and finally paroled. A lengthy article on the McNary correspondence can be found in the Confederate Philatelist of Oct. 1961. $0 (Image)
