O’Hara offered the sword of surrender to Rochambeau, who refused and directed O’Hara to give it to Washington. Washington also refused and instructed O’Hara to give it to his second in command, Benjamin Lincoln. At that point, the British soldiers laid down their arms between the American and French armies.

Significance of the Battle of Yorktown
The Battle of Yorktown was significant because it was the last major battle of the American Revolutionary War. The British forces, under the command of Lieutenant General Charles Cornwallis, were forced to surrender to French and American forces led by General George Washington. The American victory sealed the independence of the fledgling United States of America and eventually led to British forces evacuating all of the positions it held in its former colonies. The American Revolutionary War officially ended when the Treaty of Paris was signed in 1783.
