Siege of Yorktown
The Siege of Yorktown (28 September to 19 October 1781) was the final major military operation of the American Revolutionary War (1775-1783). It resulted in the surrender of British general Lord Charles Cornwallis, whose army had been trapped in Yorktown, Virginia, by George Washington's Franco-American army on land, and by Comte de Grasse's French fleet at sea.

War Comes to Virginia
In the spring of 1781, as the American War of Independence approached its sixth year, the British came to Virginia. 1,500 British troops under the command of the American turncoat Benedict Arnold landed at Portsmouth in January, going on to capture and burn the city of Richmond. Arnold was joined two months later by 2,300 more men under Major General William Phillips; together, Phillips and Arnold defeated a Virginia militia force at Blandford in late April before going on to burn the tobacco warehouses at Petersburg. They remained in Petersburg as they awaited the arrival of Lord Charles Cornwallis, who was marching up from North Carolina with 1,500 men, the survivors of the costly British victory at the Battle of Guilford Court House. Cornwallis reached Petersburg on 20 May, several days after General Phillips had died of a fever. Arnold returned to New York in June, leaving Cornwallis in sole command of the combined British army, which numbered over 7,200 men.
Cornwallis was not supposed to be in Virginia. Indeed, Sir Henry Clinton, commander-in-chief of the British forces and Cornwallis' superior officer, had ordered him to merely suppress Patriot resistance in the Carolinas. A task that had, at first, appeared easy enough soon turned into a quagmire, as Patriot and Loyalist militias tore each other to bloody shreds in the South Carolinian backcountry. All the progress Cornwallis had made in pacifying the country quickly unraveled after two defeats at the Battle of Kings Mountain and the Battle of Cowpens. Even his eventual victory at Guilford Court House left a bitter taste in his mouth, as he had lost over 25% of his army and had allowed the elusive American general Nathanael Greene to slip through his fingers. It was clear that his strategy would have to change if he wanted to win the South, no matter General Clinton's orders. His solution had been to invade Virginia. Greene and the Carolinian militias counted on supplies and reinforcements from the Old Dominion; should Virginia fall, Cornwallis calculated the rest of the South would fall with it.
Now, with the strength of Arnold's and Phillips' armies added to his own, Cornwallis put his plan into motion. He first struck toward Richmond, sending a small American army under Gilbert du Motiers, Marquis de Lafayette, running, before dispatching raiding parties into Virginia's heartland to seize supply depots and disrupt lines of communications. Lt. Colonel Banastre Tarleton and his dreaded British Legion were sent to Charlottesville, where Governor Thomas Jefferson and the Virginia General Assembly had relocated after the burning of Richmond; warned of Tarleton's coming, Jefferson and all but seven of the legislators managed to escape into the mountains mere minutes before 'Bloody Ban' arrived to apprehend them. Finally, on 25 June, Cornwallis' main army arrived triumphantly in Williamsburg. It might have been the start to a glorious conquest – had Cornwallis not received fresh orders from General Clinton the very next day.

The orders were for Cornwallis to suspend military operations in Virginia. Clinton had learned that a sizable French fleet was sailing up from the West Indies, and he feared that New York City (where Clinton himself was located with 10,000 men) was its target. Cornwallis, therefore, was to go on the defensive, march to the nearest deep-water port – Clinton recommended Portsmouth or Yorktown – fortify it, and wait there for further orders. Cornwallis was deeply frustrated by these instructions, as he believed that it was in Virginia where the war would be won. Nevertheless, he did as he was told. He marched out of Williamsburg, pausing only to lay an ambush for Lafayette's pursuing army; the resulting Battle of Green Spring (6 July) bloodied Lafayette's force but did not destroy it. Cornwallis pressed on, ultimately choosing Yorktown as his destination. By 6 August, he had landed his troops there and had begun to fortify both Yorktown and Gloucester Point, just across the York River.
