The Battle of Yorktown Context
Since the opening shots and volleys at the Battles of Lexington and Concord, the American and British troops moved around the American continent, engaging in battle, for more than six years. Both armies were near the point of exhaustion. The Americans were experiencing issues with funding and paying soldiers' wages, enlistments were ending, and their troops were split. A force resided in the north outside of New York City, and a depleted force in the south had been victorious but taken heavy casualties. The British were fighting on foreign soil, their supply lines stretched across the Atlantic Ocean, and they were also at war with France and Spain, incurring heavy debt and growing weary of their fight with the Americans.
Since the American victory at the Battle of Saratoga, the northern campaigns had become a defensive engagement. The British were happy to hold the city of New York, and the Americans, under the command of General George Washington, were happy to keep them in the town. The British held New York and embarked on a new strategy to invade the south. Initially, the British successfully took Savannah and Charleston and moved inland. However, by 1780, the British found themselves backed up to the coast after several devastating American attacks, such as the Battle of Cowpens and Camden. The British retreated to the city of Wilmington, North Carolina, under the command of Charles Lord Cornwallis. He desperately needed more men and supplies and, anticipating a resupply, moved his 9,000 troops north to a peninsula in Virginia to occupy the town of Yorktown.
Did you know? By the spring of 1781, Washington had to decide whether to engage the British garrison in New York City or move his army south to join the Southern Continental Army and engage the forces at Yorktown. Washington and his French counterpart, General Comte de Rochambeau, decided to move south, as the French fleet would sail out of the Caribbean and would have the ability to meet them in Virginia at an early date than if they were to sail to New York.
The Battle of Yorktown Summary
The Battle of Yorktown is not typical. It lasted almost a month; it was a siege.
Battle of Yorktown Date
By the fall of 1781, the British forces under Cornwallis were embattled and dug into defensive positions in Yorktown, awaiting much-needed reinforcements. Washington received word that the French navy could move out of the Caribbean and rendezvous near Virginia. Washington anticipated using the naval guns and the army artillery to lay siege to Cornwallis’s troops.
Did you know? Washington moved his 8,000 men south to join General Nathanael Greene’s Southern Army of 12,000 men and other militia. Their allied force with the French outnumbered the British force in Yorktown almost two to one.
September 5, 1781: French and British Naval Engagement
On September 5, as Washington and Rochambeau were en route south, the French fleet, under the command of Admiral Comte de Grasse, intercepted the British fleet sailing south to re-enforce Cornwallis near the Chesapeake Bay. The Battle of the Capes began in a quick but violent engagement off the coast that saw the British defeated and forced to return to New York, abandoning Cornwallis. The French fleet took up an embargoed position around the cape near Yorktown and prepared to lay siege with cannons.
Embargoed position
A physical blockade of naval ships surrounding an enemy position to cut off food supplies and munitions and block any means of retreat.
September 28, 1781: Washington’s Army Arrived outside of Yorktown
After an intense 400-mile march from New York City, Washington’s Northern Continental Army and Rochambeau’s French units' combined forces arrived at Yorktown on September 28, 1781. Washington prepared for an immediate siege of the town and attacked the British defenses around the city.

The Allied forces began a plan of offensive trench warfare. The armies dug parallel trenches up to the British redoubts to cover the advancing troops from the entrenched British artillery. Though the British attempted to stop the advancing trenches, their efforts fell short, and Cornwallis was wary of using up his minimal supply of artillery shells.
Redoubts
A temporary defensive fortification often consisting of mounds of dirt and timber, usually in geometric shapes emphasizing defenses forward and not to the flanks.
October 9, 1781: The Allied Barrage Began
The trenches were completed by the morning of October 9. Before Washington gave the order to advance on the British defenses, he engaged the artillery in a massive barrage of the town and the British defensive redoubts. “Three 24-pounders, three 18-pounders, two 8-inch (203 mm) howitzers, and six mortars, totaling 14 guns”1 began to fire upon and pound the British position constantly.
Did you know? They continued this unrelenting fire for a week, creating gaps in the British line and devastating British morale.
October 11, 1781: Allied Troops Advanced
Under cover of the continuous barrage of land and naval cannon, the armies dug an additional parallel trench closer to the British positions in the gaps created by the artillery attacks. Though the British successfully stopped the American forces from extending the trenches to their desired locations near the river, by the morning of October 12, all channels leading to the British were complete.
October 14, 1781: The Attack Began
The attack began with a diversionary assault at 6:30pm to make the British believe the Allied forces were attempting to attack the town. While that attack began, the actual American forces, under the command of Alexander Hamilton, moved under cover of darkness with stealth to attack the British redoubts defending the city.
Having not loaded their muskets and fixed bayonets, the American forces moved down the trenches with 400 men. The Americans arrived at the fortifications and began to dismantle them with hatchets. The hacking alerted the British, who opened fire. However, the British were too close and too outnumbered to be effective. After intense hand-to-hand combat, the Americans overwhelmed the British defenses, inflicting heavy casualties on the British while taking very few.

At the same time, the French sent troops to attack other redoubts and pushed the British back into the town. After the built-up defenses fell, Cornwallis found himself surrounded by artillery on three sides: the French navy surrounding the peninsula and more Allied artillery positioning themselves in the former British positions.
Did you know? To save face, Cornwallis ordered a counterattack on October 15, which was unsuccessful.
October 17, 1781: The British Began to Capitulate
On the morning of October 17, Lord Cornwallis sent an officer and drummer boy to the front of the British lines with a white flag tied to a sword. The blindfolded officer was brought to General Washington to secure the terms of surrender of the British forces.
October 19, 1781: Cornwallis Surrendered his Forces at Yorktown
In a nearby field, Cornwallis officially surrendered his British and Hessian troops to George Washington.

Battle of Yorktown Significance
The surrender of Lord Cornwallis’s force marked the end of the British war effort, and besides some outlier battles with indigenous allies of the British and pockets of Loyalist resistance, ended the military conflict between the Americans and the British in the Revolutionary War.
The reports of the surrender in London on November 25, 1781 solidified the war's end for many worn-down Britons, who saw the war as too costly and incurring too many casualties. Parliament ordered peace negotiations to begin on March 5, 1782. The American delegation, led by John Adams and the British representatives, took two years to negotiate the peace and independence of the American colonies, now states under the Articles of Confederation. Though the process took a couple of years, the Treaty of Paris was signed on September 3, 1783. The victory at Yorktown had won the war for the Americans.
