I was taught ( in the US - Pennsylvania) that the US lost just about everything - in fact, the only victory was the Battle of New Orleans (?) that was actually fought AFTER the war was over but before word had reached the Americas. Plus there's that whole burning of the capital.

That said, it wasn't taught as a loss that we should learn any lesson from. Much like the Revolutionary War, it was just "oh heck, those crazy Brits vs the indomitable American spirit again!" If we weren't good allies of the British today, I wonder what the teaching would be like...
