Answer:
RIGHT, It was on a peninsula and easily surrounded by enemy ships.
Step-by-step explanation:
American troops in command of Lafayette staged raids Cornwallis and held him in the South.
Cornwallis made a blunder mistake. He should send the part of his Army to the North but he brought them to the Yorktown peninsula.
George Washington saw this moment as a great opportunity to ambush Cornwallis on the peninsula.
Also, the French fleet under Admiral de Grasse headed over to cut off Cornwallis.
