The backglass shows a man on horseback on a moonlit night in colonial Boston apparently signaling a conveniently awake and fully dressed citizenry of something behind him. The scene likely is intended to portray Paul Revere's historic midnight ride to Lexington on April 18, 1775 to warn Samuel Adams and John Hancock that British troops were on the march to arrest them. In the background, a light shines from the bell tower of Boston's Christ Church. However, Revere didn't start his journey on horseback until after he had left Boston, having been first rowed across the Charles River to Charlestown by associates, and there he borrowed a horse to start his ride. Fellow patriot William Dawes was also dispatched from Boston to Lexington for the same reason as was Revere, but Dawes was the one who took the land route through Boston. Therefore, history would have the man on horseback in Boston be William Dawes.
