4.6 Kiowa and Cheyenne leaders pose in the White House conservatory with Mary Todd Lincoln (standing far right) on March 27, 1863, during meetings with President Abraham Lincoln, who hoped to prevent their lending aid to Confederate forces. The two Cheyenne chiefs seated at the left front, War Bonnet and Standing In the Water, would be killed the next year in the Sand Creek Massacre.
