I can only imagine the politics, negotiations, and “acts” some folks must have been engaged in. With a mix of loyalists, neutral, and pro-war perspectives, and at times not knowing whom you met supported what position, it must have been a very tense and uncertain time. Also with Britain being such a world power, likely many people found some plan to be seen as loyal for as long as possible.
I do imagine there were folks who spied for the British. How high their ranks in the colonial army though I’m not too sure.
