Indeed...one of my favorite stories was the Quaker woman from Philly who gave him key information before Germantown, I believe. Another one relates to the NJ hunter/trapper (quite a character, he) who informed on troop movements. He never seemed to have trouble getting people to risk it all for him and the Patriot Cause...one reason was that they trusted him completely.
A few years ago we visited the Delaware Crossing and heard about Washington’s exploits, and shrewdness in his Christmas attack on the British. Remarkable man, trying to keep his army together in the face of unbelievable obstacles. And, yes there were stories of intrigue from “pillow talk” messages received from girl friends of the British officers giving Washington valuable humintel in a timely manner!
