This photo shows a war party of Brul’ Indians, many wearing war bonnets, on horseback. Brul’ (‘burned’ or ‘burnt thighs’) were a subtribe of the Teton division of the great Dakota tribe. They are mentioned by Lewis and Clark (1804) as the Tetons of the Burnt Woods, numbering about 300 men, who rove on both sides of the Missouri, White, and Teton rivers.””
