Cornwallis surrenders at Yorktown as the band plays “The World Turned Upside Down.” The American war is effectively over.
THE MOMENT IN CONTEXT
It begins at the ✕ by Boston: on 19 April 1775, redcoats marching to seize militia gunpowder trade fire at Lexington and Concord and lose 273 men on the retreat. For six years the war seesaws — Washington’s genius is less winning battles than keeping an army in being while Congress keeps a cause in being. The British arrows on your map show the plan that should have worked: Howe takes New York, then Philadelphia; Burgoyne drives down from Canada to cut New England off. But Burgoyne’s column dies in the woods at Saratoga in October 1777 — and that defeat, more than any victory, decides the war, because it convinces France the rebels are a sound investment.
From Chapter 2 — The American Revolution of The Age of Revolutions, 1775–1848 (SEP 1783).

- What it changed — A constitution that exports. The state constitutions, then the federal one of 1787 — written, ratified, amendable — turn Enlightenment theory into working precedent. Every…
Then ask the room: Britain had the world’s best navy, deepest purse and most professional army. Make the case that it could never have won. The argued answer is on the chapter page →
