Final answer:
British General Charles Cornwallis was the one who confronted Washington after the Battle of Trenton.
Step-by-step explanation:
British General Charles Cornwallis was sent to confront Washington after his win at Trenton. General George Washington achieved a significant victory at the Battle of Trenton, where he surprised and defeated the Hessians on December 26, 1776. This victory was followed by another successful attack on British forces at the Battle of Princeton on January 3, 1777. Washington's bold actions during this period were critical in boosting the morale and unity of the colonial forces during the American Revolutionary War.
