The Siege of Yorktown Begins: The Battle That Won American Independence
On September 28, 1781, General George Washington led a combined force of American and French troops to surround British General Charles Cornwallis and his army at Yorktown, Virginia — setting in motion the final, decisive campaign of the American Revolutionary War. What followed over the next three weeks would not merely be a military victory. It would be the birth cry of a nation finally breaking free from the most powerful empire on earth.
The road to Yorktown had been long and brutal. For six years, the Continental Army had suffered freezing winters at Valley Forge, devastating defeats in New York, and a war that seemed perpetually on the verge of collapse. Washington himself had endured mutinies, supply shortages, and a Congress that could barely keep his soldiers fed. But by the summer of 1781, the strategic pieces had finally aligned in America's favor in a way they never had before.
The French alliance, secured in 1778, proved to be the turning point that made Yorktown possible. French Admiral de Grasse sailed his powerful fleet into the Chesapeake Bay, defeating a British naval force at the Battle of the Chesapeake on September 5th and cutting off any possibility of Cornwallis receiving reinforcements or escaping by sea. When Washington and French General Rochambeau marched their combined force of roughly 17,000 soldiers into position around Yorktown on September 28th, Cornwallis found himself in an iron trap with approximately 8,000 men and dwindling supplies.
The formal siege operations were a masterpiece of 18th-century warfare. Allied engineers dug parallel trenches advancing toward British fortifications under fire. On the night of October 14th, in one of the most celebrated moments of the entire war, Alexander Hamilton led a bayonet charge that stormed and captured the critical Redoubt No. 10, dramatically shortening the siege. The pressure became unbearable.
On October 19, 1781, Cornwallis — claiming illness — sent a subordinate to formally surrender his entire army. As British soldiers marched out to lay down their arms, the military band reportedly played a tune called "The World Turned Upside Down." For the British Empire, it quite literally had been.
Though the formal Treaty of Paris would not be signed until 1783, Yorktown effectively ended major combat operations in America. The siege that began on September 28th shattered British political will to continue the war and confirmed what many had begun to believe — that a ragged, determined collection of colonies had done the impossible. They had defeated the greatest military power of their age and, in doing so, changed the course of human history forever.
