Actually, most of the War of 1812, the British thumped the Americans, because instead of continuing to fight them in an unconventional matter, America tried using a green, conventional army against their seasoned soldiers. This generally doesn’t work.
However, Britain’s war goals were muddled. They knew they couldn’t conquer America, so it was more a punitive expedition, America resenting its sailors being cashiered as near slaves on British warships, to fight the French navy, and fighting the British about it. Then the whole thing became moot because of Napoleon Bonaparte getting thumped in Russia and turning back to the West.
It was settled with the Treaty of Ghent, which likely fewer than one in a hundred thousand Americans have ever heard of. The British have even less interest in it, seeing it as a minor sideshow to the Napoleonic wars.
Probably the biggest losers were the eastern Indian tribes, who the long-memoried Andrew Jackson eventually ethnically cleansed as punishment for supporting the British.
The war of 1812 seems to have wrecked quite a few British military careers in the process. The people in Canada and Great Britain did not look favorably upon Henry Proctor over the slaughter of wounded captives at Frenchtown.
The Americans expected a certain degree of humanity from the Brits so they surrendered their wounded so they would get care. Instead Proctor took his troops and returned to Canada leaving the wounded in the care of the indians who proceeded to slaughter them in their beds.
It naturally enraged the Americans and I’ve read that it drew attention to an area of operations that had been largely ignored and the British were routed.
AJ was indeed a man who could hold a grudge. However, the Cherokee and other tribes fought on the American side, and they were equally cleansed eventually.
Just finished a book about Lewis and Clark, Aaron Burr and what was going on at this time.
Quoted letters from President Jefferson to his negotiators with the tribes. Makes it utterly clear that Jefferson and his group never had the slightest intention of maintaining treaties with Indians. In an intensely dishonest way, the treaties were intended to keep the tribes quiet for a few years till it because more convenient to break the treaties and dispossess them.
It appears the Federalists under Washington and Adams had intentions to establish permanent treaties intended to be honored, but doing so apparently never crossed the minds of the Democrat/Republicans.
