The war was fought in a number of disconnected campaigns, hundreds of miles apart. We held Lake Ontario and Central Ontario. We burned Washington, but got beaten at Baltimore and New Orleans. And crucially, we lost the Battle of Lake Erie to Commodore Perry. This meant we had to evacuate Indiana and Northern Ohio and Western Ontario. As the Americans held Lake Erie, they could isolate and destroy any British and Canadian units who were left West of Brantford. And that pretty much did it for an Indian state in the Midwest - which would not have lasted for more than 10 or 15 years anyway. There were a lot of Americans and they really, really wanted that land.
Even if we had "won" the War of 1812, the US would still be a super power today. Britain basically wanted to beat Napoleon and defend Canada. It didn't have any real strategic interest in the land south of the great lakes. The borders would probably have ended up exactly as they were in any event.
I wonder if the Indians could of held land if we had given them the land we promised, they would have needed our protection and how long would that have lasted
We never defeated America because of some bad leadership in a couple of crucial battles
The battle of new Orleans occurred after the treaty of Ghent but no one knew the war was over, so it does not count as a loss
If I was a foot soldier for the British I would have wanted to be posted in Kingston
The fort was so strong the Americans considered attack futile and it was never attacked
The fort at Niagara is reconstructed as the original was burned down along with the town
only the churches were not burned and they stand today
