Powder River

the long version

The Great Sioux War of 1876–77 began at daybreak on March 17, 1876, when Colonel Joseph J. Reynolds and six cavalry companies struck a village of Northern Cheyennes -- Sioux allies -- thereby propelling the Northern Plains tribes into war. The ensuing last stand of the Sioux against Anglo-American settlement of their homeland spanned some eighteen months, playing out across more than twenty battle and skirmish sites and costing hundreds of lives on both sides and many millions of dollars. And it all began at Powder River.
