We didn't exactly "win" the war. We had some successful ground victories that forced the Royal Expeditionary Force into a position where they would be destroyed, but that wasn't even a fraction of England's might and they would've been replaced quickly. In reality, it was our Navy sinking and capturing their merchant vessels that ended the war. The businessmen demanded their gov't end the war because they were losing too much money.
Also, we declared the war that is known as The War of 1812. They were capturing our merchant ships and pressing our sailors into service in their navy. Prior to the war we were trading with both the french and the British but England refused to acknowledge our neutrality.
Back on topic: I also do not like Valentine's Day. I'm thinking of celebrating it as "Bitter Singles Day" for people like me who rarely have a girlfriend and are forced to put up with overbearing people who wonder how you can go through life without a constant companion.
