You are not ignorant. The Mcdonald papers are an extreamly obscure referance. They are a collection of stories about the R-War written down circa 1830. The papers/books have never been transscribed into print. They were recopied before the typewritter. Later, they were microfilmed. There may only be two copies in existance. One in maybe in Bedford (I don't know the state). I found the other in NY. It belongs to the Westchester Hist Soc. The papers are not redily available.
Even though the content of the stories is subject to embelishment the story tellers name names. They also sometimes comment on an a character in the story as to their personality our how they looked.
I can tell you this the Refugees were mostly terrorist. Do not get me wrong. The Yankees played the same game. At night both sides slipped behind enemy lines. They usually looted someone they knew to be an enemy and had a nice horse or something else that was easily moved. Had there been recent house burnings or murder they would return the favor. New York city needed beef and the British needed horses. The main source of these were from the Loyalists. The other name for the Refugees was cowboys. They were all excellant horsemen as well as being very daring.
