Sometimes a war with an external power is very uniting. I did not learn this until the bicentennial of the War of 1812 when I was many decades older than your campers.
Yes, we covered that. There was not actually a winner in the War of 1812. All the boundaries reverted to status quo ante bellum. The way they were before the war. But Americans felt it was a big win because there was for the first time a feeling of nationalism and pride in being an American. There was no true winner but definitely the Native Americans were big losers.
