On what date did the British army surrender at Yorktown, a turning point recalled by America250?

The British army surrendered at Yorktown on October 19, 1781, a turning point recalled by America250.

Lieutenant General Charles Cornwallis surrendered his army to the allied forces of George Washington and the French commander Rochambeau after the Siege of Yorktown. French naval control of the Chesapeake helped prevent British relief from reaching the besieged army.

Yorktown did not immediately end the war. Fighting and negotiations continued for nearly two more years, until the Treaty of Paris was signed in 1783. However, the defeat weakened British political support for continuing the conflict and made a negotiated settlement much more likely.

The surrender ceremony is sometimes confused with the treaty that formally ended the war. Yorktown was the decisive military victory; the Treaty of Paris provided the diplomatic conclusion.
