Final answer:
Lord Cornwallis, William Howe, John Burgoyne, and Henry Clinton were all British commanders in the American Revolution, leading campaigns and battles against the Continental Army, with Cornwallis's surrender marking the war's effective end.
Step-by-step explanation:
Lord Cornwallis, William Howe, John Burgoyne, and Henry Clinton all have in common that they were British commanders during the American Revolution. These men played significant roles in major campaigns and battles against the Continental Army, which sought independence from British rule. For instance, General William Howe led the British forces in the early years of the war, including taking control of New York City, while Lord Cornwallis is notably remembered for his surrender at the Siege of Yorktown, which effectively ended the war in favor of the American colonies.
