General Nelson Appleton Miles entered the military in 1861 at the age of twenty-two, and by forty-one he was a brigadier general. By 1895, he was the commanding general of the U.S. Army. Particularly successful in dealing with the Indian wars from 1869 to 1886, he is pictured above meeting with Sitting Bull shortly after General George Custer's defeat in 1876. The crushing military losses at Little Bighorn redoubled the United States' determination to campaign against the Sioux. Using Fort Keogh on the Yellowstone River as his base, General Miles pursued Sitting Bull and Crazy Horse throughout the winter and spring of 1876. By that October, Miles's efforts had driven Sitting Bull into exile in Canada.
