American troops under General Hull demanded that the British and Canadian troops surrender, but they wound up seizing key spots instead. American forces surrendered even though they had a much larger force.
British forces, under General Robert Ross, captured the nation's capital and ordered the burning of Washington in revenge of the crushing defeat for the British in the Battle of York in which Americans sacked the capital of Upper Canada, York (Toronto). The British hoped that the retaliatory burning of Washington would embarrass and demoralize the American nation.
British forces under Alexander Cochrane, George Cockburn, and Robert Ross decided to sail up to Chesapeake Bay and strike the port of Baltimore. However, Baltimore's citizens have worked on their defense for a year. British attacked them from the harbour and on land, but the defenses never gave up. British decided to go for the American flag, but it wouldn't give up ither. They surrendered and the flag still stands.
