Describe the poignant scene that Exeter witnessed on the battlefield.

During the battle, Exeter saw the Duke of York attempting to comfort the Earl of Suffolk even though York was also injured and dying. Exeter heard York tell Suffolk to stay alive long enough so that they could keep each other company on the way to heaven. When York saw Exeter, he asked him to be sure to mention his service to the king, then he turned back to his dying friend, Suffolk.
