What military strategy defeated Cornwallis at Yorktown?

It is said that someone in the woods fire their gun three times hide until all the soldiers came toward them then surprised attacked the soldiers that came to the woods to check where the firing came from. Then again this is just a rumor, I don't necessarily know what exactly happened but you should get at least an idea of what happened.
