Actually you're wrong about that making no sense. In the official account, Paul Revere referred to his people as Americans.
"I observed a wood at a small distance, and made for that. When I got there, out started six officers on horseback, and ordered me to dismount. One of them, who appeared to have the command, examined me where I came from and what my name was: I told him. He asked if I was an express: I answered in the affirmative. He demanded what time I left Boston: I told him; and added that their troops had catched aground in passing the river, and that there would be five hundred Americans there in a short time for I had alarmed the country all the way up."
