Could Beatty lose Lion even if the Royal Navy sank Goeben?
Short answerYes. A lucky German hit could cost Britain Lion, although that outcome is judged unlikely because individual ship tactics were one of Beatty's strengths.
NotesA victory over Goeben could still cost Britain Lion. A lucky hit keeps that risk in the counterfactual, even when the British ship has better prospects. The expectation of success rests partly on Beatty's competence in individual ship command.
