Sorry - perhaps slightly outside HK, and maybe I should already know this, but where were the American troops stationed in southern China during the Boxer Rebellion? I have an instance of a man leaving that army and then joining the government service in Hong Kong in 1901 (a British citizen) so presumably not that far away?  Or did they spend all their time on troop-ships?  Any ideas? thanks
