Could a stronger Taranto raid change which British battleships later hunted Bismarck?
Short answerYes; crippling more Italian battleships could let R-class ships hold the Mediterranean while Queen Elizabeths reinforce the Home Fleet and Nelson or Rodney protect convoys.
NotesA larger carrier force at Taranto might leave Italy with only one or two older operational battleships. R-class ships could then cover Mediterranean requirements while modernized Queen Elizabeths moved north. Nelson and Rodney might become convoy escorts, presenting Bismarck or Tirpitz with opponents they could not safely attack. The counterfactual connects one strike's results to theater allocation, convoy protection, and German raider choices.
