When did charles cornwallis retreat north to virginia

On this day in 1781, British General Charles Cornwallis formally surrenders 8,000 British soldiers and seamen to a French and American force at Yorktown, Virginia, bringing the American Revolution to a close.

"Although the war persisted on the high seas and in other theaters, the Patriot victory at Yorktown effectively ended fighting in the American colonies. Peace negotiations began in 1782, and on September 3, 1783, the Treaty of Paris was signed, formally recognizing the United States as a free and independent nation after eight years of war."

Hopefully I helped!
