Exhausted from six long years of fighting for independence, General George Washington and the US Continental Army needed a decisive win against the British forces. With the support of the French, in 1781, the Continental Army marched from New York to Yorktown, where British General Cornwallis’ troops were garrisoned and awaiting supplies from the Royal Navy.
Encountering the French fleet in the Chesapeake Bay, the Royal Navy never delivered those supplies to Cornwallis. This gave Washington the perfect opportunity to win the war.
Running low on artillery, Cornwallis’ forces could do little to stop the Continental Army’s trench building. Once in range, the American’s were able to continuously bombard the British encampment, causing devastating casualties.
Finally, in a coordinated attack, the French and Continental armies decimated the camp and won a surprising victory over the British. Disgusted, General Cornwallis was a no-show at the surrendering ceremony, sending his second-in-command instead.
Already weary of the war, when news of the surrender hit England, British Prime Minister Lord North declared the war over and resigned weeks later. Despite independence not officially being recognized until the 1783 Paris Treaty, Yorktown was the last military operation of the Revolutionary War. Effectively ending the war.
