Fort Atkinson has been called the "top historical spot in Nebraska," the "SAC of 1820," and "America's most important Western outpost." Once the country's largest fortress beyond the Missouri River, its garrison protected America's interests in the burgeoning fur trade, provided a base camp for explorations, played host to famous frontiersmen, and was the site where numerous treaties were signed. But by 1961, Fort Atkinson was endangered. The fort's buildings had vanished over 100 years before. Decades of farming on the land had nearly erased its footprint. A housing development threatened to obliterate the site forever. There was only a marker with a flagpole raised in 1927 by the Daughters of the American Revolution--a lonely object in the midst of an empty plain. This book tells the story of how that lost fortress was restored to become the major state historical park it is today.
