America declared its independence in 1776, but it took another five years to win freedom from the British. That day came on October 19, 1781, when the British General Charles Cornwallis surrendered his troops in Yorktown, Virginia.
General Cornwallis brought 8,000 British troops to Yorktown. They expected help from British ships sent from New York. The British ships never arrived. That was lucky for General George Washington and the Continental army. The thirteen colonies found their opportunity to beat the world's largest empire.
