I found this book one of Mr. Grey's finer writings, perhaps due to his emotional and familial attachment to the subject. The feel of the time is very real and still written with contemporary digestability. Not to be overlooked by fans of Zane Grey or historical novels.

From Wikipedia: Elizabeth "Betty" Zane McLaughlin Clark (July 19, 1759 – August 23, 1823) was an alleged heroine of the Revolutionary War on the American frontier. She was the daughter of William Andrew Zane and Nancy Ann (née Nolan) Zane, and the sister of Ebenezer Zane, Silas Zane, Jonathan Zane, Isaac Zane and Andrew Zane.

According to a historical marker in Wheeling, on September 11, 1782, the Zane family was under siege in Fort Henry by American Indian allies of the British. During the siege, while Betty was loading a Kentucky rifle, her father was wounded and fell from the top of the fort right in front of her. The captain of the fort said, "We have lost two men, one Mr. Zane and another gentlemen, and we need black gunpowder."

Betty Zane's father had buried a store box of black gunpowder in their cabin. Betty Zane volunteered to leave the fort to retrieve more supplies...

Betty Zane's great-grandnephew, the author Zane Grey, wrote a historical novel about her, titled Betty Zane. One of the main events in the story is the tale of Zane's fetching supplies from the family cabin. When Grey could not find a publisher for the book, he published it himself in 1903 using his wife's money. Grey later named his daughter Betty Zane after his famous aunt.
