In October of 1776 Elizabeth Frye wrote to her husband Isaac, who was encamped with his regiment at Camp Independence on the eastern shore of Lake Champlain opposite Fort Ticonderoga. In her letter, she wrote, “See me before you Engage another Season X. I have no desire you Should Heyht your Duty, but if you are not behind hand in the Cause of Liberty, I shall wish for your Company.”

While I researched the path Isaac took during the American Revolution, her words crystallized into the title for the book I intended to write. Little did I know, I had enough material for four books.

This site contains higher resolution maps, scans of some of the source material, and a blog where I comment on the books and the research.

Charles E. Frye is a geographer, cartographer, information scientist, and U.S. Army veteran. His interests include genealogy, history of the American Revolutionary War, and major league baseball. As he learned of Isaac Frye’s story, he applied his skills to design an approach to use geographic information systems to organize and document historical research projects. Applying this approach to Isaac Frye’s story yielded a wealth of information that could be organized many ways. This supplied the skeleton for the The War has Begun, the first of four books in the Duty in the Call of Liberty series. Today he lives and works in southern California.
