At which battle did the Americans and French surround the British forcing them to surrender? Trenton Saratoga Yorktown Brandywine

The answer is the Battle of Yorktown. The last British Army in the area was led by General Cornwallis. The army retreated to the town of Yorktown. But then they were attacked. The British tried to escape by sea but the recently allied French had their navy blocking the British ships from escaping. While the French were blocking their escape by sea, the combined army of the Colonist and the French attacked by land. With no hope of escape or reinforcements, the British surrendered. This marked the last battle of the Revolutionary War.
