His father was Horn Cloud and mother Nest, both parents died at the Wounded Knee Massacre along with two brothers William Horn Cloud (1876-1890), Sherman Horn Cloud (1865-1890) and a niece. Joseph was a survivor of the massacre as well as his brother Daniel and half brother Dewey Beard [p. 89-95]. Dewey's mother was Yellow Leaf who also died during the massacre. In the early 1900s a writer named Eli S. Ricker began research for a book he was going to call "The Final Conflict between the Red Men and the Palefaces." He gathered sources and interviews about conditions and battles on the Plains during the last half of the 1800s. He recorded the interviews in small note pads known to historians as the "Ricker Tablets." One such interview was with Joseph telling Ricker what he witnessed at the Wounded Knee Massacre, "When the shooting began the women ran to the ravine. The shooting was in every direction. Soldiers shot into one another... Many of the Indians in the circle were killed. Many of them mingled with the soldiers behind them, picking up guns from dead soldiers and taking cartridge belts."

Crow Dog was one of the leaders who helped popularize the Ghost Dance. On August 5, 1881, after a long simmering feud, Crow Dog shot and killed principal chief Chief Spotted Tail (who was also at the Grattan massacre), on the Rosebud Indian Reservation. A grand jury was convened and he was tried and convicted in Dakota Territorial court in Deadwood, South Dakota, and sentenced to death which was to be carried out on January 14, 1884. He was imprisoned in Deadwood pending the outcome of his appeals. According to historian Dee Brown in his bestselling book, "Bury My Heart at Wounded Knee":

Flying Hawk's life chronicles the history of the Oglala Lakota people through the 19th and early 20th centuries, as he fought to deflect the worst effects of white rule; educate his people and preserve sacred Oglala Lakota land and heritage.

He fought alongside his first cousin Crazy Horse and his brothers Kicking Bear and Black Fox II in the Battle of the Little Big Horn in 1876, and was present at the death of Crazy Horse in 1877 and the Wounded Knee Massacre of 1890. Chief Flying Hawk was one of the five warrior cousins who sacrificed blood and flesh for Crazy Horse at the Last Sun Dance of 1877. Chief Flying Hawk is notable in American history for his commentaries and classic accounts of the Battle of the Little Big Horn, Crazy Horse and the Wounded Knee Massacre, and of Native American warriors and statesmen from who fought to protect their families, defend the invasion of their lands and preserve their culture. Chief Flying Hawk was probably the longest standing Wild Wester, traveling for over 30 years throughout the United States and Europe from about 1898 to about 1930.
