The Siege of Yorktown was the final major land campaign of the American Revolutionary War<\/a>, fought from September 28th to October 19th, 1781, at the town of Yorktown, Virginia. A combined American and French force of approximately 17,000 soldiers, led by General George Washington<\/a> and French General Comte de Rochambeau, surrounded and bombarded a British army of roughly 8,000 men under General Lord Charles Cornwallis. Unable to escape by land or sea, Cornwallis surrendered on October 19th, 1781. The victory effectively ended the Revolutionary War<\/a> and secured American independence.<\/p>\n\n\n\n

What Was the American Revolution?<\/h2>\n\n\n\n

The American Revolution<\/a> was the political and military struggle through which the Thirteen Colonies<\/a> broke free from British rule and established the United States of America. By the summer of 1781, the war had been dragging on for more than six years, and both sides were exhausted. Britain still controlled several major port cities and had a large army in North America, but the will to continue fighting was fading at home. For the Americans, the need for a decisive victory had never been more urgent. The Siege of Yorktown delivered that victory and brought the Revolution to its conclusion.<\/p>\n\n\n\n

Background \u2013 Cornwallis in Virginia<\/h2>\n\n\n\n

After his costly victory at the Battle of Guilford Court House in North Carolina in March of 1781, British General Cornwallis led his battered army into Virginia. He conducted a series of raids across the state through the spring and early summer, destroying supplies and threatening the American forces under the Marquis de Lafayette<\/a>, who had only about 4,500 men and could not risk a direct confrontation.<\/p>\n\n\n\n

British General Henry Clinton, commanding from New York, ordered Cornwallis to take up a defensive position on the Virginia coast where the Royal Navy could support or reinforce him if needed. Cornwallis chose the port town of Yorktown, situated on a peninsula between the York River and the James River. The location seemed relatively secure, as long as the British Navy controlled the surrounding waters. Cornwallis set his men to building a network of ten earthen forts called redoubts, connected by trenches and artillery batteries, around the town. By August of 1781, his army of approximately 9,000 men was dug in and waiting for naval support.<\/p>\n\n\n\n

Washington’s Decision to March South<\/h2>\n\n\n\n

Washington had spent much of 1781 positioned near New York City with his Continental forces and the French army under Rochambeau, debating whether to attack the British in New York or to move south against Cornwallis. The decision was made for him in August of 1781, when word arrived that French Admiral Comte de Grasse was sailing north from the Caribbean with a large fleet and would be available to support operations in the Chesapeake Bay area until mid-October.<\/p>\n\n\n\n

Washington immediately recognized the opportunity. He ordered Lafayette and his forces in Virginia to block Cornwallis’s escape by land and keep him penned on the Yorktown peninsula. Then Washington executed one of the most impressive strategic deceptions of the war. He ordered the construction of large camps and bread ovens near New York, visible to the British, to create the impression that a major assault on the city was being prepared. False papers discussing attack plans on New York were allowed to fall into British hands. Under cover of this deception, Washington and Rochambeau quietly marched their combined force of approximately 7,000 men south in mid-August, covering 200 miles (320 km) in 15 days. By the time the British in New York realized what was happening, it was too late to respond.<\/p>\n\n\n\n

<\/div>\n\n\n\n

The Battle of the Chesapeake<\/h2>\n\n\n\n

The most critical single event of the entire Yorktown campaign took place at sea, not on land. On September 5th, 1781, de Grasse’s French fleet met a British fleet under Admiral Thomas Graves at the mouth of the Chesapeake Bay in what became known as the Battle of the Chesapeake, or the Battle of the Capes. The French won decisively, forcing the British fleet to return to New York for repairs. With the British navy gone, de Grasse established a naval blockade of the Chesapeake, cutting Cornwallis off from any possibility of reinforcement or escape by sea. The war on land was effectively decided at this moment. No army trapped on a peninsula with its naval lifeline severed could hold out indefinitely against a superior besieging force.<\/p>\n\n\n\n

De Grasse then transported Washington and Rochambeau’s forces down the Chesapeake Bay to Virginia. By September 28th, 1781, approximately 17,000 American and French soldiers had assembled outside Yorktown and begun the siege. The French held the left flank and the Americans the right. Cornwallis’s position was now surrounded on three sides by land and sealed off by sea.<\/p>\n\n\n\n

Major Events of the Siege of Yorktown<\/h2>\n\n\n\n

Washington’s strategy was methodical and methodical. Rather than launching costly frontal assaults against Cornwallis’s fortifications, the allies would use the classic techniques of siege warfare, digging parallel trenches closer and closer to the British lines and moving heavy artillery forward to pound the defenses into collapse.<\/p>\n\n\n\n

The first parallel trench was completed on October 6th, running roughly 800 yards (730 m) from the British outer defenses. Artillery was moved up and the bombardment began on October 9. Washington himself reportedly fired the first allied cannon shot. The combined Franco-American artillery pounded the British positions relentlessly. Within two days most of Cornwallis’s guns had been silenced. The British garrison suffered casualties from the constant bombardment and began to run short of food, water, and ammunition. Disease, particularly malaria, added to the suffering. Cornwallis later estimated that half his army was too ill to fight by the time of the surrender.<\/p>\n\n\n\n

To push the siege closer to the British lines, the allies needed to capture two key British defensive positions, Redoubt 9 and Redoubt 10, which were blocking the construction of a second parallel trench. On the night of October 14th, 1781, Washington ordered simultaneous assaults on both positions. A French column under Vicomte de Deux-Ponts stormed Redoubt 9. An American column of 400 light infantry under Lieutenant Colonel Alexander Hamilton attacked Redoubt 10, moving silently through the dark with bayonets fixed and muskets unloaded to maintain surprise. Both assaults succeeded in under thirty minutes. With the two redoubts taken, the second parallel trench was completed and the allied artillery now stood just 400 yards (365 m) from the British main line.<\/p>\n\n\n\n

Cornwallis attempted a desperate last-ditch effort on the night of October 16th, sending soldiers to spike the allied guns in a counterattack that was quickly repulsed. He then tried to evacuate his army across the York River by boat, but a sudden storm scattered the boats and the attempt failed. His situation was hopeless.<\/p>\n\n\n\n

The Surrender<\/h2>\n\n\n\n

On the morning of October 17th, 1781, a lone British drummer boy appeared on the parapet of the British lines, beating a signal for a ceasefire. A British officer followed, waving a white cloth to signal the desire to negotiate. Washington and Cornwallis exchanged messages, and on October 18th, four officers, one American, one French, and two British, met at the Moore House outside Yorktown to settle the terms of surrender.<\/p>\n\n\n\n

The formal surrender ceremony took place on October 19th, 1781. Cornwallis claimed to be ill and did not attend, sending his second-in-command, Brigadier General Charles O’Hara, in his place. More than 8,000 British soldiers and sailors marched out between two long lines of American and French troops that stretched for over a mile. The British bands played as the soldiers laid down their arms and their flags. O’Hara attempted to surrender Cornwallis’s sword to Rochambeau, but the French general declined and directed him to Washington. As Cornwallis was not present, Washington in turn directed O’Hara to surrender to his own second-in-command, General Benjamin Lincoln. In total, Cornwallis surrendered 7,087 officers and men, 900 seamen, 144 cannons, 15 galleys, a frigate, and 30 transport ships. A British relief fleet carrying 7,000 men sailed from New York but arrived five days too late.<\/p>\n\n\n\n

When news of the defeat reached London, Prime Minister Lord North reportedly collapsed and exclaimed, “Oh God, it is all over.” Parliament voted in March of 1782 to authorize negotiations for peace, and Lord North resigned. Peace talks in Paris eventually produced the Treaty of Paris<\/a>, signed on September 3rd, 1783, which formally recognized American independence.<\/p>\n\n\n\n

Significance of the Siege of Yorktown<\/h2>\n\n\n\n

The Siege of Yorktown was the decisive military event of the American Revolution. It demonstrated what the Franco-American alliance was capable of when properly coordinated, combining land forces, naval power, and strategic deception into an overwhelming trap that the British could not escape. Washington’s bold decision to march south, de Grasse’s control of the Chesapeake, and the methodical execution of the siege all contributed to a victory that ended eight years of war.<\/p>\n\n\n\n

For the United States, Yorktown was the moment independence became real. The new nation had staked everything on a revolution against one of the most powerful empires in the world and won. The victory established Washington’s reputation as one of the great military commanders of his era and set him on the path to becoming the first president of the United States. The Yorktown battlefield is today preserved as part of Colonial National Historical Park in Virginia, a permanent reminder of the campaign that gave birth to a nation.<\/p>\n","protected":false},"excerpt":{"rendered":"
