On June 17, 1891, several Grand Army of the Republic posts of East Tennessee came together at Allentown for a reunion. Many of the veterans of the regiment attended the event.
A Regimental Association was formed in 1896 following a reunion of the men of Company G. The first treasurer was Henry Lineback.
According to the regimental history: "At the reunion held at Mountain City in September, 1898, a resolution making all Union veterans of Carter and Johnson, and adjoining counties, associate members of this association, was adopted." It is not unusual to read about or see photos with men from other Union Army regiments included in the proceedings.

- "Out of the 1,177 members of the original company, only 28 are living, only 10 attending the reunion. Only one officer, Capt. J. J. McCorkle, is living. Those attending were: Capt. J. J. McCorkle, of Johnson City; John Gray, of Greeneville; John Loveless, of Watauga Valley; M. P. Elliott, of Johnson City, N. K. McIntosh, of Unicoi; D. J. W. Rowe, of Conklin; G. J. Birchfield, of Milligan; J. C. Jackson, of Johnson City, A. Q. Arnold, of Neva; D. J. Slemp, of Baker's Gap." More than 28 veterans were still living, but the Regimental Association was undoubtedly aware of that fact. Many of the names here were misspelled or use incorrect initials. John J. McCorkle served as quartermaster sergeant of Company H; he was discharged in January 1865 to accept a commission as a captain in the 1st United States Colored Heavy Artillery. Thus, all of the regiment's officers were deceased by 1931.
