Would a different senior commander aboard Courageous have prevented her wartime loss?
Short answerLittle change is expected for Courageous; for Glorious, a different commander probably would have kept aircraft airborne and a cruiser close.
NotesCourageous and Glorious need to be distinguished before considering this counterfactual. Courageous was sunk by a submarine, and changing her senior commander is judged unlikely to alter that outcome. For Glorious, a different commander could have kept aircraft airborne and a cruiser in close attendance. Those are the specific precautions proposed, rather than a guarantee that replacing a commander would save either ship.
