Yorktown (1781): The Real Siege That Ended the War
Military History: The War of US Independence
Chapter 9 · Yorktown (1781): The Real Siege That Ended the War
Every earlier chapter's own thread converges here — the army Chapter 4 built at Valley Forge, the French alliance Chapter 6 secured at Saratoga, and the naval encirclement Chapter 8 delivered at the Chesapeake all combine in a single, decisive three-week siege.
A Real, Deceptive March South
On 19 August 1781, Washington and the French general Rochambeau departed New York with a real, combined force of roughly 7,000 troops (4,000 French and 3,000 American), employing genuine deception tactics — deliberately sending false dispatches suggesting a planned siege of New York, to keep Cornwallis and the British high command genuinely uncertain of their real objective. The march passed through Philadelphia, where Rochambeau provided a real, crucial infusion of hard currency — twenty thousand Spanish silver dollars — after American troops, real, understandably reluctant to continue on worthless Continental paper currency, refused to march further without proper payment.
The Siege Itself
The siege of Yorktown lasted three real weeks, from 28 September to 19 October 1781. The combined Franco-American force facing Cornwallis was genuinely overwhelming: American forces of roughly 8,000-9,000 (5,900 regulars and 3,100 militia), joined by 10,800 French troops and 29 French warships, against a British and German garrison of roughly 8,000-9,000 (about 5,000 British and fewer than 3,000 German troops).
Land Forces
American: 5,900 regulars + 3,100 militia. French: 10,800 troops. Combined against Cornwallis's own roughly 8,000-9,000 defenders — real numbers this course's earlier chapters set the stage for directly.
Naval Support
29 French warships, the direct, real payoff of Chapter 8's own Battle of the Chesapeake — with Cornwallis's own resupply and evacuation routes already sealed off before the siege even began.
Facing an increasingly hopeless position, Cornwallis requested capitulation terms on 17 October 1781, with the formal surrender ceremony taking place two days later, on 19 October.
An Honest Correction: The Surrender Song
The popular story that a British military band played "The World Turned Upside Down" during the surrender ceremony is real, widely repeated folklore — but genuinely unverified. No primary source confirms it actually happened; the story remains, at best, unconfirmed tradition rather than documented historical fact.
Cornwallis's Real Absence
Cornwallis himself did not attend the surrender ceremony in person, citing illness. Brigadier General Charles O'Hara led the British delegation in his place — first attempting to offer his sword to Rochambeau, who genuinely refused it and gestured toward Washington instead. Washington, in turn, declined to accept the surrender personally, directing O'Hara instead to his own second-in-command, Major General Benjamin Lincoln. The signed articles of capitulation, dated 19 October 1781, granted British and German officers parole to return home and promised humane treatment for captured troops — though Washington notably refused a proposed article that would have protected Loyalists from post-war punishment.
Looking Ahead
The closing capstone, Chapter 10, covers the war's real military legacy — from the 1783 Treaty of Paris through the genuine institutional challenge of building a permanent national army out of the temporary, war-winning force this course has traced from Lexington to Yorktown.
