Book excerpt: The battle that unfolded at the Little Big Horn River on June 25, 1876, marked a watershed in the history of the Plains Indians. While a stunning victory for the Sioux and Cheyenne peoples, it initiated a new and vigorous effort by the U.S. government to rid the west of marauding tribes and to realize the ideal of "Manifest Destiny." While thousands of books and articles have covered different aspects of the battle, few if any have analyzed the tactics and chronology to arrive at a satisfactory explanation of what befell George Armstrong Custer and the 209 men who died alongside him. This volume seeks to explain the circumstances culminating in the near-destruction of the 7th Cavalry Regiment by a close examination of timing, setting every event to a specific moment based on accounts of the battle's participants.
