Burning of Washington [SEP] Introduction
The Burning of Washington was a British invasion of Washington City (now Washington D.C.), the capital of the United States, during the War of 1812, and part of the Chesapeake Campaign. On August 24, 1814, after defeating the Americans at the Battle of Bladensburg, a British force led by Major General Robert Ross set fire to multiple government and military buildings, including the White House (then called the "Presidential Mansion"), the Capitol building, as well as other facilities of the U.S. government. The attack was in part a retaliation for the recent American destruction of Port Dover in Upper Canada.
