Final answer:
The Battle of Yorktown was an important turning point in the American Revolution, as it led to the surrender of the British army and the eventual independence of the thirteen colonies.
Step-by-step explanation:
The importance of the Battle of Yorktown was that the British army under General Cornwallis surrendered to a combined American and French army in the last major battle of the war. This victory marked a turning point in the American Revolution, as it led to the eventual independence of the thirteen colonies from British rule. The surrender at Yorktown effectively ended the military conflict and set the stage for the signing of the Treaty of Paris in 1783, which formally recognized the United States as an independent nation.
