Benedict Arnold was still a patriot then.
He saved the Revolution at Saratoga.

I stand corrected. My chronology was confused. Washington was headquartered in Philadelphia the winter of 1776-77. Battle of Trenton was Dec. 26, 1776. Saratoga, as you point out, was Oct. 1777. Valley Forge winter was 1777-78. So we still don't know who the spy was. I wonder if there's any way to find out.
