Who would win a War of 1812 fight between USS Constitution and HMS Shannon?
Short answerThere is no certain winner. The first effective shots, together with wind and luck, would probably decide the fight.
NotesNeither USS Constitution nor HMS Shannon is an automatic winner. Both were capable ships, leaving the engagement sensitive to wind, luck, and which crew landed the first effective shots. That answer resists judging a duel from reputation or specifications alone. It also anticipates the later discussion of how operational conditions can outweigh paper performance.
