What if CSS Virginia defeated USS Monitor?
Short answerIt would not change the Civil War's outcome, because infrastructure and logistics mattered more than one ironclad victory.
NotesVirginia's plausible route to victory would require an unusual ramming opportunity after Monitor became disabled or missed an evasive move. With both ships capable of roughly six knots, forcing that encounter against a functioning Monitor would be difficult. Even a Confederate tactical victory would not overturn the conflict's larger balance. Infrastructure and logistics, rather than élan, prestige, or possession of the most advanced single weapon, decide wars of this scale. A separate counterfactual remains open for viewers: how might a Virginia victory have changed later ship design?
