Lord Fairfax stayed neutral during the American Revolutionary War. Just a few weeks after the surrender of British troops under General Cornwallis at Yorktown, he died at his home at Greenway Court on December 9, 1781, at the age of 90. He was entombed on the east side of Christ Church in Winchester. While his plans for a large house at Greenway Court never materialized, and his stone lodge is now gone, a small limestone structure he had built still exists on the site.
