Siege of Yorktown order of battle

The British Army forces present at Yorktown arrived in Virginia in four separate detachments. The first was sent from New York City in December 1780 under the command of Brigadier-General Benedict Arnold. The second was sent from New York in March 1781 under the command of Major-General William Phillips to reinforce Arnold after a Franco-American threat. The third detachment to arrive was that of General Charles Cornwallis, who had been active in the Carolinas and, following the Battle of Guilford Court House on March 15, decided to join forces with Arnold and Phillips. This was contrary to instructions from his superior, Lieutenant-General Sir Henry Clinton, the Commander-in-Chief, North America. He arrived at Petersburg, Virginia in late May to take command of the troops there; Phillips had died of a fever just a week before, and Arnold returned to New York not long after Cornwallis arrived. While at Petersburg, Cornwallis was joined by a fourth detachment from New York that was under the command of the Hessian Colonel August von Voigt. With this force, numbering about 7,200, Cornwallis first chased after the army of the Marquis de Lafayette, a much smaller force of Continental Army and local militiamen that had provided some resistance to the movements of Phillips and Arnold. Cornwallis was eventually ordered by Clinton to establish a fortified deep-water port at either Yorktown or Portsmouth. Cornwallis chose Yorktown, and began constructing fortifications there and Gloucester Point, just across the York River from Yorktown, in August 1781. British forces Commander: Lt. Gen.

The American forces that opposed Cornwallis at Yorktown also arrived in Virginia at different times, since most of the detachments were made in reaction to the British movements. After Arnold was sent to Virginia, General George Washington, the American commander-in-chief, in January 1781 sent the Marquis de Lafayette to Virginia with 900 men. He was to be followed promptly by troops from the Pennsylvania Line under the command of Brigadier General Anthony Wayne, but Wayne did not arrive in Virginia until June. Lafayette's force included a substantial number of Virginia militia, and he shadowed Cornwallis during the movements that ended at Yorktown, with a skirmish at Spencer's Ordinary and a larger battle at Green Spring being their only significant encounters. The main Continental Army of General Washington was at first stationed outside New York City, which Washington hoped to besiege with the assistance of the French army. However, word from Admiral Paul de Grasse of the French West Indies fleet would sail north to assist in operations on the Chesapeake Bay convinced Washington that action was best taken against Cornwallis's army in Virginia. Accordingly, the American and French armies set out in mid-August for Virginia. Some troops went overland the entire way; others were transported on the Chesapeake by ships of the French Navy. Washington arrived in Lafayette's camp before Yorktown on September 17. • Commander, General George Washington, commanding • Headquarters • 4th Continental Light Dragoons • Armand's Legion • Artillery under Brigadier General Henry Knox • 1st Continental Artillery Regiment (10 company), Lieutenant Colonel Edward Carrington, Captain Whitehead Coleman • 2nd Continental Artillery Regiment (9 companies), Colonel John Lamb • 4th Continental Artillery Regiment (3 companies), Captains Patrick Duffy, William Ferguson, and James Smith • Sappers and Miners (4 companies) • Light Division, under Major General Marie-Joseph Paul Yves Roch Gilbert du Motier, Marquis de La Fayette • 1st Brigade, commanded by Brigadier General Peter Muhlenberg • Colonel Joseph Vose's Battalion (8 Massachusetts light infantry companies) • Lieutenant Colonel Jean-Joseph Sourbader de Gimat's Battalion (5 Connecticut, 2 Massachusetts, and 1 Rhode Island light infantry companies) • Lieutenant Colonel Francis Barber's Battalion (2 New Hampshire, 2 New Jersey, and Canadian Regiment light infantry companies and 3 New Jersey line companies) • 2nd Brigade, commanded by Brigadier General Moses Hazen • Lieutenant Colonel Alexander Scammell's battalion (3 New Hampshire, 3 Massachusetts, 3 Connecticut light infantry companies, 1 Rhode Island light platoon under Lieutenant Benjamin Sherburne) • Lieutenant Colonel Alexander Hamilton's Battalion • Weedon's Virginia Militia Battalion • 2nd Brigade, commanded by Brigadier General Robert Lawson • Lawson's Virginia Militia Battalion • 3rd Brigade, commanded by Brigadier General Edward Stevens • Steven's Virginia Militia Battalion ==French Army==

French troops at Yorktown came from two separate sources. The larger force (known as the Expédition Particulière), which was under the command of Lieutenant-General Jean-Baptiste Donatien de Vimeur, comte de Rochambeau, landed at Newport, Rhode Island in 1780 and marched overland to join Washington's army outside New York in the summer of 1781. These troops marched with Washington's army from New York to Yorktown. More French troops were transported by boat on the Chesapeake than Americans, due to the French navy's preference for transporting their own soldiers. The second source for French troops was the colony of Saint-Domingue, where de Grasse picked up more than 3,000 soldiers under the command of Major-General Claude-Anne de Rouvroy de Saint Simon before departing for North America. French ground forces were also supplemented by a number of marines provided by de Grasse in support of the siege. French units at the siege of Yorktown included: • Commander Lt. Gen. Jean-Baptiste Donatien de Vimeur, comte de Rochambeau • Commander of Artillery, Lt. Col.
