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.

A Fitting Final Correction for This Course This course has now made an honest correction of this exact kind — a vivid, quotable detail that turns out to be poorly supported by the real historical record — at Bunker Hill (Ch. 3), Flamborough Head (Ch. 8), and now Yorktown itself. This pattern is worth naming explicitly rather than treating each instance as an isolated coincidence.

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.

Reflect

Question 1 This course has now corrected three separate popular but poorly-supported details across its own chapters (Bunker Hill, Flamborough Head, and Yorktown's surrender song). Why might these specific kinds of vivid, dramatic details tend to attach themselves to already-famous historical moments?
Question 2 Cornwallis's own real absence from his own surrender ceremony, and the careful, deliberate chain of officers who ultimately accepted it on Washington's behalf, involve a genuine amount of formal military etiquette. What might this careful protocol suggest about how seriously 18th-century military culture treated the symbolism of surrender itself?
Question 3 Yorktown brings together threads from nearly every prior chapter of this course — the army trained at Valley Forge, the French alliance from Saratoga, and the naval action at the Chesapeake. What does this convergence suggest about how a single decisive victory is often the product of many earlier, less dramatic developments coming together at once?

Chapter 9 Quick Reference

  • Combined march: departed New York 19 August 1781, ~7,000 troops, with deliberate deception tactics
  • Siege of Yorktown: 28 September – 19 October 1781
  • Forces: ~8,000-9,000 American, 10,800 French troops + 29 warships, vs. ~8,000-9,000 British/German defenders
  • Surrender song: "The World Turned Upside Down" story is genuinely unverified folklore
  • Cornwallis's surrender: he did not attend in person; Brigadier General Charles O'Hara surrendered to Benjamin Lincoln on Washington's behalf
