Siege of Yorktown, 28 Sept – 19 Oct 1781

In September and October 1781, Washington's Continental Army and Rochambeau's French expeditionary force trapped Lord Cornwallis's British army at Yorktown, Virginia, after the French fleet under de Grasse defeated the Royal Navy at the Battle of the Capes. The allies dug siege lines, bombarded the town, and on 14 October stormed the two redoubts that blocked their second parallel. With no hope of relief or escape, Cornwallis surrendered his army of about 8,000 men on 19 October. The defeat brought down Lord North's government and led to the Treaty of Paris of 1783, in which Britain recognized American independence.

The battle, stage by stage

  1. 28–30 Sept 1781

    The allies close in

    Washington's 8,800 Americans and Rochambeau's 7,800 French march down from Williamsburg and encamp in a great arc around Yorktown, the French on the left (west), the Americans on the right. Cornwallis, with about 9,000 men, holds the town and Gloucester Point across the river, waiting for a British fleet that de Grasse's victory at the Capes (5 September) has turned away. On the night of 29–30 September he abandons his outer works.

  2. 3 Oct

    Skirmish at the Hook, Gloucester

    Across the York, Choisy's French and Virginians, led by Lauzun's Legion, clash with Tarleton's dragoons at the Hook and pen the Gloucester garrison inside its works for the rest of the siege.

  3. 6–9 Oct

    The first parallel

    On the night of 6–7 October, under cover of rain, allied troops dig a trench some 2,000 yards long, 600–800 yards from the British lines. Washington fires the first American gun on 9 October; the Grand French Battery and the American batteries begin a bombardment that silences most British guns and burns ships in the river.

  4. 14 Oct, evening

    Assault on Redoubts 9 and 10

    The second parallel, opened on 11 October about 300 yards from the British works, is blocked at its eastern end by two redoubts. At 8 PM two columns of 400 men attack with unloaded muskets: Alexander Hamilton's light infantry against Redoubt 10, the Comte de Deux-Ponts's French grenadiers against Redoubt 9.

  5. 14 Oct, night

    Both redoubts taken

    Hamilton's men carry Redoubt 10 in about ten minutes; the French take Redoubt 9 after a harder fight. By morning both are linked into the second parallel and allied guns can now fire into the town at point-blank range.

  6. 16 Oct

    Sortie and failed escape

    Before dawn Lt. Col. Abercromby leads 350 men in a sortie that spikes several guns in the second parallel before being driven back. That night Cornwallis tries to ferry his army across to Gloucester and break out; the first wave crosses, but a squall scatters the boats and the attempt is abandoned.

  7. 19 Oct

    The surrender

    After a parley on the 17th and terms signed at the Moore House on the 19th, the British garrison marches out between the lines of French and Americans and grounds its arms at Surrender Field; the Gloucester garrison surrenders to Choisy. Some 8,000 men become prisoners. Lord North, hearing the news, exclaims "O God! It is all over."

Sources and method

Siege of Yorktown, 28 September – 19 October 1781. Positions follow the US Military Academy (West Point) map of the siege (via Wikimedia Commons), pinned to modern terrain at Redoubts 9 and 10 and the Nelson and Moore houses, with camp, trench and surrender-ground positions from the standard accounts and the National Park Service layout of the battlefield. Treat positions as good to about 100–200 m; the West Point map gives the redoubt assault date as 10 October, but it took place on the 14th. The overlay is schematic: it lines up around the siege works but drifts by a few hundred metres at the camps, Surrender Field and Gloucester Point.
