This is a very old “local” B&W card of what is now called “Battle of the Windmills Historic Site”.  We knew nothing of the background, so we looked it up and were interested to see that 300 Americans invaded Canada in 1838 (the card says 1837) with the idea that Canadians would rather be Americans, and when the Americans lost this battle, many were sent off to Australia.  We suspect there’s more to the story, but the card is here waiting for you.  Grade: 1
