In 1874, Fort Robinson was founded amid the piney ridges of northwest Nebraska to stem the attacks of the Sioux, angered by settlers encroaching on the High Plains and by gold prospectors invading their sacred Black Hills. Fort Robinson's residents--including black troops, members of the Ninth and Tenth Cavalry Regiments--were divided by rank and sometimes by race.   Schubert makes clear the vital importance of Fort Robinson during the Sioux wars, including the Ghost Dance Uprisings of 1890, and he blends social analysis with military history in his concern for the families of soldiers and civilians.
