Yes. We lost. The ground war went very badly from the US point of view. The Canadian militia were pretty tough and their Indian allies were a real problem since they thought that prisoners were there for their entertainment. Hey! Some of our Indian ancestors were probably in the British force, but the real story were the British Army Regulars. They dominated every battlefield except New Orleans and maybe Lundy's Lane. These stunted little men from the slums of the English industrial towns and the blighted lands of the Scottish enclosures and crofts were much better soldiers than anything the US had at that time.
These soldiers had been fighting in Europe for a generation. As Clausewitz wrote, there is nothing that so perfects an army as actual war.
At sea, the situation was quite different as I suppose we all know. The American heavy frigates did well against the Royal Navy.
The fictional Napoleonic era British soldier "Richard Sharpe" said of himself that he "was born in a whorehouse and hoped to die in the Army." His character is an accurate depiction of the kind of men who beat the United States in that war. pl
