In her photograph of Chief Flying Hawk, his glare is the most startling image among those portraits by Käsebier, quite contrary to the others who were shown as relaxed, smiling, or making a "noble pose". Flying Hawk was a combatant in nearly all of the fights with United States troops during the Great Sioux War of 1876. He fought along with his cousin Crazy Horse and his brothers, Kicking Bear and Black Fox II, in the Battle of the Little Big Horn in 1876. He was present at the death of Crazy Horse in 1877 and the Wounded Knee Massacre of 1890. In 1898, when the portrait was taken, Flying Hawk was new to show business and he was unable to hide his anger and frustration about having to imitate battle scenes from the Great Plains Wars for Buffalo Bill's Wild West in order to escape the constraints and poverty of the Indian reservation. Soon, Flying Hawk learned to appreciate the benefits of a Show Indian with Buffalo Bill's Wild West. Flying Hawk regularly circulated show grounds in full regalia and sold his "cast card" picture postcards for a penny to promote the show and to supplement his meager income. After the death of Iron Tail on May 28, 1916, Flying Hawk was chosen as his successor by all of the braves of Buffalo Bill's Wild West and he led the gala processions as the head Chief of the Indians.
