Published in the Rome Tri-Weekly Courier, Jul. 27, 1875, page 4.
I assume the sword was captured. This offer to return it was made more than ten years after the war ended. I searched for an Adjutant named Bishop in the 87th Illinois, but was unable to locate one. Maybe someone else can locate him? Unfortunately, the name of the person offering to return the sword is not included in the article.
It bears the following inscription: "Presented to Adjutant E. F. Bishop, 87th Regiment Illinois Volunteers, September 3d, 1862."
