On October 17, 1781, a drummer left the British defensive works at Yorktown, Virginia. An officer followed, waving a white handkerchief, and was soon blindfolded and brought behind the lines of the Continental Army and their French allies to discuss the conditions of surrender for the British troops under Lord Cornwallis.
Washington agreed to all the Articles of Capitulation except the 10th which sought to pardon Americans who had fought with the British at Yorktown and Gloucester because he considered that a civil matter.
After some negotiation, on October 19, 1791, the Articles of Capitulation were signed and the battle of Yorktown was over. That day, General George Washington wrote to Congress informing them of the victory.
Yorktown was the last major land battle of the American Revolution and prompted Britain to negotiate the Treaty of Paris which officially ended the war in September of 1783.
