Maj. Andre was head of British Mil Intel. In the show TURN: Washington’s Spies (TV Series 2014-2017) you really admire the guy in many respects and they do a good job making you despise Benedict Arnold. Definitely a show I highly recommend. Good stuff! Will get you thinking. Every episode is good.
Kenneth Roberts books - this one, his second, ‘Rabble in Arms’ is about Benedict Arnold and his betrayal
