The pistol was examined by Wendell Grangaard of The Guns of History and found to be marked in Togia, a Lakota language with the paperwork included. The gun is marked with the name Robe and the Grass Dancer Band mark (illustrations 1, 2, & 3). Robe, sometimes referred to as Robe Hari Outside, was an Oglala Lakota Sioux warrior, born in 1852. He was selected by Crazy Horse to become a Grass Dancer. This special unit was initially headed by Crazy Horse and later by Black Bear. The band consisted of 13 warriors, with the sole purpose to guard Paha Sapa (also known as Black Hills). During the Indian Wars from 1876-1877, the Grass Dancer band and Knife were moved from Paha Sapa and used by Crazy Horse to scout the location of the soldiers together. Robe went with Crazy Horse and the rest of the Oglala and surrendered on April 18, 1877. Robe and his family settled on the Red Cloud Indian.
