This is an iconic book of American history. First published in 1947, it details the settlement of eastern the eastern US in the 18th century. I bought the book at the Cumberland Gap National Monument. After Daniel Boone and 30 ax men widened an ancient Indian trail to open the western land beyond the Appalachians, over the next 25 years, 200,000 to 300,000 people poured into TN & KY. The privation, suffering, determination, and loss suffered by both the Native Americans and the pioneers, mostly Scots-Irish, defies modern sensibilities.
