Dear Bernard
After reading the Fort which I loved btw, I wondered if you have ever considered another 1 more 1 off book on the American Revolution, on the Siege of Quebec, since it had Maclean from the Fort at that Action. It also had some of the Top commanders on both sides such as Arnold and Morgan on the American side and Guy Carleton on the British and that victory arguably changed history in that it kept Canada separate rather than part of the US.
You also might find this article interesting to read on some of the Loyalist Regiments that served in the war.
Yours sincerely
Geraint
