Captain Robert Goldthwaite Carter (October 29, 1845 - January 4, 1936) served as an officer in the U.S Cavalry, both during the Civil War and the Indian Wars. He received the Medal of Honor for single-handedly holding off a Comanche raiding party in Blanco Canyon near the Brazos River (Texas) on October 10, 1871. The citation reads: "Held the left of the line with a few men during the charge of a large body of Indians, after the right of the line had retreated, and by delivering a rapid fire succeeded in checking the enemy until other troops came to the rescue." Carter authored several books, the most notable of which pertaining to this collection being On the Border with Mackenzie (1935). It documented his service under Colonel Ranald Mackenzie in northern Mexico in the late 1870s, and about his service more generally during the Indian Wars.The Robert G. Carter Papers consists of correspondence between Captain Carter and researchers, manuscript publishers, family members, and others. It bulks with correspondence about On the Border with Mackenzie (1935), but also documents discussions about his other manuscripts, concerning their contents as well as their sale and distribution. A small amount of correspondence with his family is present, as are correspondence relating to his finances. Lastly, two folders of material consist exclusively of letters exchanged with Clifford B. Jones of the Swenson Cattle Company (and the Spur Ranch) and Freeport Sulphur Company
