Theodore Roosevelt, The Winning of the West.
Reading now, and haven't quite got to the Revolution yet, but the details that he lays out with the expansion of the American frontier on the westward side of Virginia, Pennsylvania, Kentucky, the men like Daniel Boone, the daily life, the armed conflict with the Indians, the traders, the frontiersmen; just incredible levels of detail. Very readable.
Completely new perspective on Captain Morgan, and his company of Riflemen. And why they were so successful.
Highly, highly recommended.
