From today’s perspective, it is difficult to appreciate the long odds faced by Americans and their French allies in the Yorktown campaign of 1781. The prospects for George Washington and his northern army at the start of the year were not bright. They were keeping a lonely vigil outside of New York City, monitoring the actions of Sir Henry Clinton's vastly superior British forces.The situation in the South also was dismal. The British commander, Lord Charles Cornwallis, completed his sweep through the Carolinas and in May entered Virginia to root out the sources of American resistance.Further, the American populace was weary of the war, the government was broke and soldiers in all theaters were not inclined to commit to lengthy terms of service.Nonetheless, it became evident to Washington and his French allies that a possible opportunity was developing to trap Cornwallis’s army in a position where they could not be resupplied or reinforced. To accomplish this, however, would require moving two armies, one American and the other French, over 450 miles to Virginia.If those movements were detected early on by the British, then the scheme would collapse and a possibly disastrous encounter would occur in the North. If Chesapeake Bay could not be temporarily sealed off from the British fleet, then Cornwallis would be reinforced by sea and stand an excellent chance of defeating his exhausted opponent in Virginia.The gamble paid off for Washington. These events included:
- Cornwallis in Virginia (May - August 1781). Cornwallis conducted raids in Virginia, refused to send troops to Clinton in New York and fortified a defensive position taken at Yorktown.
- Washington and Rochambeau to Virginia (August - September 1781). Washington initially favored an attack on British positions in New York in 1781, but later when his hand was forced, did a masterful job of moving his army to the southern theater.
- Battle of the Capes (September 5, 1781). Good fortune, solid French seamanship and British ineptitude contributed to denying Admiral Graves the opportunity to reinforce or evacuate Cornwallis's army at Yorktown.
- Siege of Yorktown (October 1781). Cornwallis's confidence in his ability to hold Yorktown declined as enemy artillery pounded his fortifications. Supplies and ammunition ran low, and an evacuation attempt failed.
- Surrender at Yorktown (October 19, 1781). The failure of Clinton's relief fleet to arrive, plus the numerical superiority of the Franco-American forces, necessitated Cornwallis's capitulation on terms approaching unconditional surrender.
