On February 7, 1812, the most violent of a series of earthquakes near Missouri causes a so-called fluvial tsunami in the Mississippi River, actually making the river run backward for several hours. The series of tremors, which took place between December 1811 and March 1812, were the most powerful in the history of the United States.

In London, Spencer Perceval, prime minister of Britain since 1809, is shot to death by deranged businessman John Bellingham in the lobby of the House of Commons. Bellingham, who was inflamed by his failure to obtain government compensation for war debts incurred in Russia, gave himself up immediately.

June 18, 1812: The day after the Senate followed the House of Representatives in voting to declare war against Great Britain, President James Madison signs the declaration into law—and the War of 1812 begins. The American war declaration, opposed by a sizable minority in Congress, had been called in response to the British economic blockade of France, the induction of American seaman into the British Royal Navy against their will, and the British support of Indian tribes along the Great Lakes frontier. A faction of Congress known as the “War Hawks” had been advocating war with Britain for several years and had not hidden their hopes that a U.S. invasion of Canada might result in significant territorial land gains for the United States.

Following the rejection of his Continental System by Czar Alexander I, French Emperor Napoleon orders his Grande Armée, the largest European military force ever assembled to that date, into Russia. The enormous army, featuring some 500,000 soldiers and staff, included troops from all the European countries under the sway of the French Empire.

During the War of 1812, American General William Hull surrenders Fort Detroit and his army to the British without a fight. Hull, a 59-year-old veteran of the American Revolution, had lost hope of defending the settlement after seeing the large English and Indian force gathering outside Detroit’s walls. The general was also preoccupied with the presence of his daughter and grandchildren inside the fort.

During the War of 1812, the U.S. Navy frigate Constitution defeats the British frigate Guerrière in a furious engagement off the coast of Nova Scotia. Witnesses claimed that the British shot merely bounced off the Constitution‘s sides, as if the ship were made of iron rather than wood. By the war’s end, “Old Ironsides” destroyed or captured seven more British ships. The success of the USS Constitution against the supposedly invincible Royal Navy provided a tremendous boost in morale for the young American republic.

Staking a tenuous claim to the natural riches of California, Russians dedicate Fort Ross on the coast north of San Francisco on September 11, 1812.

One week after winning a bloody victory over the Russian army at the Battle of Borodino, Napoleon Bonaparte’s Grande Armée enters the city of Moscow, only to find the population evacuated and the Russian army retreated again. Moscow was the goal of the invasion, but the deserted city held no czarist officials to sue for peace and no great stores of food or supplies to reward the French soldiers for their long march.

During the War of 1812, British and Indian forces under Sir Isaac Brock defeat Americans under General Stephen Van Rensselaer at the Battle of Queenstown Heights, on the Niagara frontier in Ontario, Canada. The British victory, in which more than 1,000 U.S. troops were killed, wounded, or captured, effectively ended any further U.S. invasion of Canada. Sir Isaac Brock, Britain’s most talented general in the war, was killed during the battle.

One month after Napoleon Bonaparte’s massive invading force entered a burning and deserted Moscow, the starving French army is forced to begin a hasty retreat out of Russia.
