What happened

In the autumn of 1781 Washington's combined American and French armies trapped General Cornwallis's British force on the Yorktown peninsula in Virginia, while a French fleet cut off escape or rescue by sea. After weeks of bombardment, Cornwallis surrendered more than 7,000 men on 19 October 1781.

Why it matters

The defeat at Yorktown broke Britain's will to continue the war and led directly to peace negotiations.
