The US burnt Britain's North American capital in York (Toronto) to the ground in 1813, Washington D.C. was in retaliation.
Also, the USS Enterprise won an incredible victory against the HMS Boxer off the coast of Maine...considering the disparities between naval power, that was pretty impressive.
Who could forget New Orleans as well. Even though it was after the war, a vastly smaller American army made up of militia men, slaves, pirates, etc. inflicted over 2000 casualties on a better trained and numerically superior British force. The most lopsided military victory in US history, they only suffered something like 70 casualties.
but yes, TWO1812 was a stalemate, good show for a country mired in debt without a professional navy or standing army, though.
