The correct answer is D, as Lord Charles Cornwallis role in the American Revolution is significant because his invasion of Virginia eventually led to his being trapped in 1781 at the Battle of Yorktown.
When the war began, Cornwallis enlisted voluntarily. In March of 1776, he left New York fighting under the command of General Henry Clinton. Between January 2 and 4, 1777, Cornwallis fought against the American continental army near Princeton, New Jersey, where, after a sudden and brilliant attack, the Americans defeated the British forces, preventing Cornwallis from counterattacking, since they withdrew on the night of the 4th. However, the battle had consisted mainly of rapid skirmishes, which did not produce great losses to the British army. Cornwallis commanded chiefly the redcoats. In 1781, Cornwallis acted in South and North Carolina, where he won the Battle of Guilford Courthouse. However, the casualties of the British in that battle were very important, so they lost the possibility of gaining control of those territories. Finally, he had no choice but to surrender, being besieged by the French and Americans, after the Battle of Yorktown, Virginia, on October 19, 1781.
