In what year was the surrender of the main forces of the British and French at Yorktown?

The surrender of British troops at Yorktown took place in 1781 during the War of Independence of the United States of America. The allied army, consisting of American and French troops (commanded by Washington and de Rochambeau, respectively), was able to defeat the British under the command of Cornwallis. Great Britain then resigned itself to the inability to keep the North American colonies under its rule and was forced to begin peace negotiations. As a result, the Paris Peace was concluded in 1783, according to which England recognized the independence of the United States.
