Another good book on this subject is
The Last Generation: Young Virginians in Peace, War, and Reunion By Peter S. Carmichael
“If all else fails, I will retreat up the valley of Virginia, plant my flag on the Blue Ridge, rally around the Scotch-Irish of that region, and make my last stand for liberty amongst a people who will never submit to British tyranny whilst there is a man left to draw a trigger.”
George Washington, at Valley Forge.
