The Last Four Days at Yorktown

The Siege of Yorktown, occurring in the latter part of 1781, stands as one of the most significant and decisive episodes in the American Revolutionary War. Its culmination, which saw the British General Cornwallis’s surrender to the combined Franco-American forces, marked the beginning of the end for British rule in the American colonies. 

By 1781, the war had raged for six long years, with both sides experiencing victories and defeats. The British, under the leadership of General Cornwallis, had shifted their strategy to the southern colonies, hoping for an easier conquest. However, after a series of battles, Cornwallis found himself moving north into Virginia, seeking logistical support from the sea and hoping to establish a fortified naval base.

Meanwhile, the Franco-American alliance was becoming more robust and synchronized. The French, under General Rochambeau, had arrived in Newport, Rhode Island, in 1780 and by 1781 had met with General George Washington in White Plains, New York. The two generals mulled over their strategy, initially contemplating an attack on New York City.

However, a golden opportunity presented itself when they learned of Cornwallis’s position in Yorktown. With the French navy, led by Admiral de Grasse, indicating its availability to support operations in Virginia, a joint strategy was formed.

The genius of the Yorktown campaign lay in its rapid mobilization and the element of surprise. Washington and Rochambeau quickly moved their troops southwards, conducting a feint towards New York to deceive the British and then swiftly marching to Virginia. The British were under the impression that New York was the primary target and were caught off-guard by the swift Franco-American maneuvers.

Simultaneously, in early September, the French naval forces under Admiral de Grasse achieved a pivotal victory at the Battle of the Chesapeake, gaining control over the waters surrounding Yorktown. This naval dominance prevented Cornwallis from receiving reinforcements or making a maritime escape.

Upon arriving at Yorktown, the combined Franco-American forces initiated a siege. Their numbers, totaling nearly 18,000 soldiers, dwarfed the 9,000 British defenders.

From September 28, the encirclement of Yorktown began, and the allies steadily dug trenches, getting closer to the British defensive lines. Artillery barrages were continuous, weakening the British morale and defenses day by day.

On October 6, a formal siege began with the construction of the first siege line. By October 9, the first artillery shells were fired upon Yorktown. Over the next few days, relentless bombardment from the allies and periodic but futile counter-attacks from the British became the norm.

The stage was now set for the final assaults and the climactic events that would follow.

The Siege of Yorktown is more than just a military operation. It epitomizes the culmination of strategic brilliance, timely cooperation, and the unwavering resolve of the American and French forces. The days leading up to mid-October 1781 set the stage for an event that would change the course of American history forever.


October 14 and 15, 1781, were pivotal days during the Siege of Yorktown, marking a significant advance for the allied Franco-American forces against the British. The assaults on Redoubts 9 and 10 played a key role in tightening the noose around the British defenses.

Colonel Alexander Hamilton, already well-known for his intellect and bravery, had long sought an active field command. Frustrated by his position as an aide-de-camp to Washington, he eventually got his opportunity at Yorktown. Some historians argue that Hamilton’s fervent insistence and desire to lead, combined with his demonstrated competence, resulted in Washington giving him command of the critical assault on Redoubt 10.

The plan for the assault was clear and precise, emphasizing surprise and speed. Hamilton’s forces would approach the redoubt with unloaded muskets, preventing any accidental discharges that could alert the enemy. Instead, they would rely on bayonets to minimize noise and maintain the element of surprise.

The night of October 14 saw Hamilton’s forces spring into action. Led by Hamilton and Lieutenant Colonel John Laurens, the American troops advanced rapidly and silently. Their bayonet charge caught the British defenders off guard. Within just 10 minutes, Hamilton’s men overran Redoubt 10, minimizing casualties.

The capture of Redoubt 10 was a swift and significant victory for the American forces. It provided them with a closer artillery position and further exposed the British inner defenses.

Almost simultaneously with the American assault on Redoubt 10, the French, under the command of Baron de Viomenil, launched an assault on Redoubt 9. Facing fierce resistance, the French employed hand grenades and a determined push, eventually capturing the position after a slightly longer engagement than the Americans.

General George Washington himself observed the assaults from a forward position. As legend has it, when a stray bullet whizzed past him, his aide reportedly urged him to step back, to which Washington remained unfazed, deeply engrossed in the unfolding action.

With the capture of these two redoubts, the Franco-American forces could now position their artillery even closer to the British defensive lines, essentially closing any gaps in the siege. The British inner defenses were now highly vulnerable, making Cornwallis’s situation increasingly dire.

After the fall of the redoubts, Cornwallis’s options became severely limited. An evacuation attempt to cross the York River and escape was thwarted by adverse weather. Retreating by land through the encircling enemy was equally infeasible. His hopes for significant reinforcements or a naval rescue were dashed by the French naval presence and the tightening Franco-American siege. Surrender began to loom as the only viable option.

The assaults on Redoubts 9 and 10, were decisive moments during the Siege of Yorktown. They exemplified the coordination and determination of the Franco-American alliance and further boxed Cornwallis into a nearly impossible situation, leading to the eventual British surrender.


On the night of October 15-16, 1781, in the shadowy backdrop of the Siege of Yorktown, a desperate bid for escape was launched by the British under General Lord Cornwallis. As the Franco-American forces tightened their grip, Cornwallis sought to evacuate his troops and attempt a breakout.

Cornwallis’s plan for evacuation was rooted in desperation but showed military astuteness. The idea was to use the cover of darkness to ferry his troops across the York River to Gloucester Point. This would allow the British to escape the immediate encirclement, regroup, and potentially find a path to join other British forces in New York.

To achieve this, Cornwallis’s engineers and troops hastily gathered every available boat and began preparations to secretly transport men, artillery, and supplies across the river.

As the night deepened, British troops began the process of quietly boarding the boats, taking care to maintain secrecy and not alert the Franco-American forces. The initial stages of the evacuation saw some troops and equipment successfully ferried across the river.

Nature, however, was not on Cornwallis’s side. As more troops began to cross, a sudden and powerful squall hit the area. The gusty winds and tumultuous waters disrupted the evacuation process. Boats were scattered, some capsized, while others were rendered unmanageable. In the face of such adversity, Cornwallis ordered a retreat, and the troops that had already crossed to Gloucester Point were ferried back to Yorktown. The evacuation had failed.

The aftermath of the failed evacuation was grim for Cornwallis. His troops were back in Yorktown, encircled with dwindling supplies and waning morale. The tightening Franco-American siege, coupled with their artillery’s proximity following the capture of Redoubts 9 and 10, meant bombardment was relentless and devastating.

With the evacuation thwarted, Cornwallis found himself trapped with limited options:

1. Attempt a Breakout by Land: This would involve a direct confrontation with the besieging forces, and given the overwhelming numbers of the Franco-American forces, success seemed unlikely.

2. Hope for Reinforcements: Cornwallis could hope for a relief force to come to his aid. However, given the dominance of the French navy in nearby waters, this too seemed a distant possibility.

3. Surrender: If all else failed, Cornwallis would have to consider the previously unthinkable: surrendering his elite army to the enemy.

The failed evacuation on the night of October 15-16 stands as a testament to the vagaries of war, where nature’s wrath can alter the course of events just as decisively as any army. For Cornwallis and his troops, the failure to evacuate sealed their fate, marking the beginning of the end of British hopes in the American Revolutionary War.


By October 17, the combined forces of the American and French armies had encircled Yorktown, systematically dismantling the British defenses. The recent capture of Redoubts 9 and 10 by the allies had brought their artillery even closer to the British defensive lines. The noose was tightening, and the pressure on Cornwallis and his men was immense.

Yorktown, initially chosen for its defensible position and access to the sea (in anticipation of British naval support), was now becoming a trap for Cornwallis. His back was to the York River, his evacuation attempt had failed, and his defenses were crumbling under the intense allied bombardment.

The strategic positioning of the Franco-American forces, especially post the capture of the redoubts, allowed their artillery to hammer the British positions incessantly. The combined artillery barrage was not only damaging the physical structures like defensive walls and buildings within Yorktown but also had a profound psychological impact.

The British defenses, built to withstand conventional sieges, were no match for the combined might of the Franco-American artillery. The town was subjected to a constant rain of shells. Buildings crumbled, protective walls were breached, and open spaces became deadly grounds due to explosive shells.

Facing the overwhelming firepower and with the situation turning increasingly bleak, Cornwallis made some key decisions on this day:

1. Relocating His Troops: Recognizing the vulnerability of his current position, Cornwallis ordered a significant portion of his troops to move to the town’s northern end, believing it to be a more defensible location and potentially a better position should another evacuation be attempted.

2. Sending a Parley: Perhaps the most significant decision Cornwallis made on October 17 was to send a drummer followed by an officer waving a white handkerchief – a universal symbol of truce. This move signaled the beginning of negotiations to end the siege, a clear indication of Cornwallis’s recognition of his dire circumstances.

3. Ceasefire: With the intent to negotiate, a ceasefire was put into place, giving both sides a momentary respite from the continuous sound of cannon fire and the horrors of the siege.

The day encapsulated the combined might of the Franco-American alliance and the culmination of their strategic and tactical supremacy over the British forces. Cornwallis’s decisions on this day, influenced by the relentless artillery barrage and the worsening situation, paved the way for the imminent British surrender and a new chapter in American history.


By October 18, the British position in Yorktown was desperate. The combined forces of General George Washington and French General Jean-Baptiste Rochambeau had successfully encircled the town. Their artillery, bolstered by the capture of key redoubts, pounded the British defenses incessantly. Furthermore, Cornwallis’s attempts to evacuate had failed, leaving him with limited options.

To facilitate the negotiation of surrender terms, both sides appointed commissioners. Representing the British was Lieutenant Colonel Thomas Dundas and Major Alexander Ross. The Franco-American side sent Viscount de Noailles, a French officer, and American Colonel John Laurens.

Cornwallis, in his initial proposal, sought the most favorable terms for his men. He hoped for the traditional honors of war, which would allow his troops to march out with their colors flying, weapons in hand, and then board ships to return to Britain, pledging not to fight in North America again during the war.

General Washington, cognizant of the British refusal to grant similar terms to American forces after the fall of Charleston in 1780, rejected Cornwallis’s original proposal. Washington insisted that the British troops march out without colors and with their muskets shouldered. This was a symbolic gesture, ensuring that the surrender looked and felt like a true capitulation.

After further negotiations, the final terms of the surrender were agreed upon:

1. British Troops: They were to march out of Yorktown, lay down their arms, and become prisoners of war. They would be treated with the respect and dignity that was customary for captured military personnel.

2. Safe Passage: British wounded and sick were to be cared for, and certain personnel were granted safe passage to New York.

3. Non-combatants: Civilians in Yorktown were allowed to return to their homes without fear of retribution or persecution.

4. Ships & War Material: All war material and ships in Yorktown were surrendered to the Franco-American forces.

October 18, 1781, was marked not by the thunder of cannons but by the quill’s scratch on parchment. The day’s deliberations epitomized the culmination of years of conflict and symbolized a new dawn for the American colonies. The terms negotiated ensured that the British surrender was complete, sealing the fate of British rule in the American colonies and edging the United States closer to full-fledged independence.
