DBWI: Mr. Madison's War is Delayed, Goes Sour

[Dean_the_Young]

I saw a trivia piece on the History Channel today on the topic of Mr. Madison's War, which pointed out the US was incredibly lucky in regards to the timing of Mr. Madison's War. Apparently, President Madison had been faced with a delima of whether to be a dove or a hawk on the issue of the British Impressment of American citizens. The History Channel noted that had President Madison waited even another year before declaring war, then there would have been the good chance that the US would not have managed to gain the highly advantageous Treaty of London while Britain was distracted by Napoleon, and may have seen Britain be able to move its veteran troops from the Continent and ship them over to the US. Considering how economically weak the US was by the end of the War in OTL, that hardly would have been a good thing.

So say Madison decides to be a voice of reason for a while longer, and the war is delayed a bit. How does the war go then? A draw? Utter annihilation/re-annexation as is the cliche in AH?
