The Battle of Bladensburg was a battle of the Chesapeake Campaign during the War of 1812, fought on 24 August 1814, at Bladensburg, Maryland, northeast of Washington, D.C. Called "the greatest disgrace ever dealt to American arms," a British force of army regulars and Royal Marines routed a combined U.S. force of Regular Army and state militia troops. The American defeat resulted in the capture and burning of the national capital of Washington, D.C., the only time that the city fell to a foreign invader. Background British plans For the first two years of the War of 1812 (1812–1815), the British had been preoccupied with the war against Napoleon and his French Empire (France) in Europe. However, warships of the Royal Navy led by Rear Admiral George Cockburn, second in command of the North American Station, controlled Chesapeake Bay from early 1813 onwards and had captured large numbers of U.S. trading vessels. They occupied Tangier Island off the coast of Virginia, establishing Fort Albion as an anchorage and staging area. As many as 1,200 British soldiers would be stationed there. Raiding parties had destroyed foundries and batteries and sacked several small towns, but lack of troops restricted Cockburn to mounting small-scale raids, the largest of which was the Battle of Craney Island, in the Hampton Roads harbor near Norfolk, Virginia, which involved 2,000 men of the British Army and the Royal Marines. Although Cockburn withdrew from Chesapeake Bay late in 1813, his sailors had taken soundings and even placed buoys to mark channels and sandbars, in preparation for a renewed campaign in 1814. By April 1814, Napoleon had been defeated and was exiled to the island of Elba off the coast of Italy, and large numbers of British ships and troops were now free to be used to prosecute the former backwater war with the United States. As part of the measures taken to prosecute the war more vigorously, Admiral Sir John Borlase Warren was replaced as commander in chief of the North American Station by Vice Admiral Sir Alexander Cochrane, who was a more active and experienced officer who often expressed his rancour with the United States. Most of the newly available troops went to Canada where Lieutenant General Sir George Prevost (who was the Governor General of Canada and commander in chief in North America) was preparing to lead an invasion into New York from Canada, heading for
