See the paragraph below, a quote taken from page 297 of my book: Rochambeau, Washington’s Ideal Lieutenant regarding the Victory Monument at Yorktown, VA memorializing the last significant battle of the American Revolution.
Lest we forget, this key battle was planned by the French under General Rochambeau and realized under the combined leadership of General George Washington, and the Continental Army along with General Rochambeau and the French Army.
“America was also busy creating her own permanent remembrance to honor Rochambeau’s victory at Yorktown. In 1781 the United States Congress provided for the construction of a monument recognizing the alliance and victory in Yorktown but failed to begin the project until one hundred years later.
The promise was kept, however, and the cornerstone was laid on October 18th, 1881, by “the order of the Ancient Free and Accepted Masons as the appropriate opening for the Yorktown Centennial celebration,” and finally completed in 1884. It consists of a base, a podium, and a slender shaft of Hallowell Maine granite.
At the top of this tall, imposing monument stands the figure of Liberty herself, a symbol of freedom from tyranny and oppression.”
On October 17, 1781, Cornwallis asks for a ceasefire. On the18th the Articles of Capitulation are written at the Moore House in Yorktown. On the morning of the 19th, the Articles of Capitulation are sent from General George Washington to the defeated General Cornwallis for his approval.
Cornwallis has no choice but to approve them. By the afternoon of the 19th, it is the official laying down of arms ceremony at Yorktown.
