7 x 5 3/8 in. albumen photograph on 12 x 10 in. cardstock mount with period notation in lower margin, "'Tchah-si-to' (White Horse) One of the principal raiders amongst the Kiowas, but one ('Big Bow') his equal, 26 years old (1873)." With "P. 41" written at lower right on mount recto and on verso. Unmarked but taken by William S. Soule.

White Horse (Tsen-tainte) was likely among the Kiowa, led by Satanta and Lone Wolf, who met Lt. Col. George Armstrong Custer, Gen. Philip Sheridan, and Col. J. Schuyler Crosby near Fort Cobb in December 1868. Satanta and Lone Wolf were taken prisoner and held until the Kiowa surrendered.

Between 1870 and 1874, White Horse took part in raids across Texas, Kansas, Colorado, and New Mexico, including the Warren Wagon Train Massacre and the Second Battle of Adobe Walls, where he played a prominent role. He surrendered in 1875 and was imprisoned at Fort Marion, returning to Indian Territory three years later, where he remained until his death in 1892.
