"The fate of a nation was riding that night;/ And the spark struck out by that steed, in his flight,/ Kindled the land into flame with its heat." (line 78-80). This metaphor describes Paul Revere as the fate of a nation and illustrates that his ride helped ignite the Revolutionary War

"And the meeting-house window, black and bare,/ Gaze at him with a spectral glare,/ As if they already stood aghast/ At the bloody work they would look upon." (97-100). This references the Battle of Lexington and Concord that happened soon after Paul Revere's ride.
