What the person above me said is true. The French were in Chesapeake Bay in their ships and the Americans on land in Yorktown. They knew this plan would work cause they had a spy named Hercules Mulligan who spied on the British government. After a week of fighting, one of the British stands on a parapet and waves a white handkerchief. Washington negotiates the terms of surrender. They then escort the British out of Yorktown.
If you watch the musical Hamilton, it'll be a fun way to learn about the American Revolution. The musical and the animatic is available on you tube, and the actual acting and on-stage singing is on Disney+.
Hope this helps! Good luck!
