Local historian Sue Gardner will present material from her new book, "Pure Necessity: Revolution at Warwick," which tells the story of the Warwick Valley during the Revolutionary War using original documents, eyewitness testimony and oral traditions.  The research was completed by the author and many volunteer transcribers over the past 20 years, as part of the Friends of Hathorn House's project to discover the true history of Gen. John Hathorn, his militia, and the people of our area during the late 1700s.  Copies will be available for purchase & signing.
