1803
Louisiana Purchase
Desperate for cash and done with his American dreams, Napoleon sold 828,000 square miles to Jefferson for fifteen million dollars - about four cents an acre. At a stroke the United States doubled. Jefferson, a strict constructionist, quietly swallowed his scruples and signed. Lewis and Clark were dispatched within months to explore what exactly he had bought, a territory so vast that its western boundary remained unmapped.
Britain Declares War on France
The Peace of Amiens collapsed over Malta, Hanover, and mutual bad faith. Britain struck first, seizing French merchantmen before declarations had dried. Napoleon massed an invasion army at Boulogne and stared at the Channel. For twelve more years there would be no peace worth the name. The resumed war would become the most expensive conflict Britain had ever fought, swallowing a quarter of the national income.
Battle of Assaye
On a baking plain in the Deccan, Arthur Wellesley - the future Duke of Wellington - led an outnumbered Anglo-Indian force against the Maratha guns and won the hardest day of his life. Assaye taught him to hate war and to trust infantry. The Maratha Confederacy's back was broken. Wellington later said Assaye, not Waterloo, was the finest thing he ever did on a battlefield.
Marbury v. Madison
Chief Justice John Marshall, in a dry little case about a judicial commission never delivered, announced that the Supreme Court could strike down acts of Congress it judged unconstitutional. He had invented, nearly from nothing, the doctrine of judicial review. Federal judges had just been made permanent referees of American self-government.
Haitian Yellow Fever Kills Leclerc
Napoleon's expedition to retake Saint-Domingue was melted by tropical disease. General Leclerc, the emperor's brother-in-law, died of yellow fever along with fifty thousand soldiers. His widow Pauline, scandalously, took her husband's body home in a coffin beside her lover. The French decision to sell Louisiana was, in part, a consequence of this rout.
Lewis Picks Clark
Meriwether Lewis wrote to William Clark, an old army friend in Indiana, inviting him to co-command the expedition Jefferson had just funded. Clark answered yes. The partnership that followed, and the quiet Lemhi Shoshone interpreter they would pick up in North Dakota, became one of the great collaborative stories in American exploration.
