Depicted in the film, Confederate Gen. Stand Watie (1806-71) was a Cherokee leader who fought for the Confederacy during the Civil War and commanded two regiments of the Cherokee Mounted Rifles. On 5/10/1864 he became the first Native American to be promoted to the rank of Brigadier General.
Studio publicity materials indicate that local Oregon tribes such as Walla Walla, Cayuse and Umatilla were used in the film to depict the Sioux.
In 1865 Red Cloud (1822-1909), chief of the Bad Face band of the Oglalas and leader of Sioux and Cheyenne bands, attacked U.S. forces in an attempt to stop the flow of settlers. Between 1865-67 Red Cloud and his braves killed Army construction troops on the Bozeman Trail and destroyed many white settlements. However, in 1868 he agreed to have his people settled on the Red Cloud Agency in Nebraska.
Stand Watie,the Native American Brigadier-General depicted in this movie, was the last Confederate Field Commander to surrender his troops to the Union at the end of the Civil War,in Oklahoma,late June 1865.
