This is the story of James, John, and Hamilton Armstrong, three sons of a yeoman farmer living on the Pennsylvania frontier at the outset of the American Revolution. James and John joined the Continental Army in 1776, rose from the ranks to become officers, and served until the army was disbanded in 1783. Hamilton remained home to work the farm, protect the family, and serve in militia and “ranger” units to defend the frontier from repeated attacks from hostile Indian tribes. Their combined wartime experiences encompassed almost the totality of the American Revolution, from Canada in the north to South Carolina in the south and along the western frontier. James and John fought in most of the major battles of the revolution, including Princeton, Brandywine, Germantown, Monmouth, Guilford Courthouse, Eutaw Springs, and Yorktown, where they distinguished themselves in the eyes of generals like the Marquis de Lafayette, Mad Anthony Wayne, Light- Horse Harry Lee, Nathanael Greene, and George Washington.
