I've had it with Britain and France! Britain has to stop impressing American sailors! They must respect our rights!
When President Madison took office in 1809, the British were still impressing sailors. He tried offering Britain and France a deal about not trading with their enemy if they would stop attacking American ships, but the deals failed.
New Englanders in the North opposed going to war with Britain because they knew it would be a blockade of their ports by the British navy. People in the South and West preferred war. They accused the British of stirring up trouble with the Indians in the west.
I run a shipping business in New England. I'd go broke if we went to war!
Yeah? Well I don't care. Those darn British are messing with the Indians near my plantation! This whole field's been ruined by them savages!
Trouble was growing with the Indians as the settlers moved into their lands. One Indian leader, Tecumseh, organized all the Indians up and down the Mississippi River and fought the settlers at Tippecanoe Creek in 1811. Later, British guns were found on the battlefield.
The "War Hawks" were Congressmen who really loved the idea of going to war with Britain. They wanted to march into Canada after the War of 1812 began.
CONQUER CANADA!!! DIE BRITISH!!!
In the war with Britain, the U.S had successes and losses. They captured a British fleet and pushed into Canada for some time, but the British invaded Washington D.C. and burned buildings like the White House and the Capitol building.
The British also attacked Fort McHenry in 1814. Francis Scott Key watched the attack, and was so inspired by the American flag still waving in the morning, he wrote a poem about it, that later became our national anthem.
