Would another vice admiral challenge Beatty's confused signals and blame Seymour afterward?
Short answerHe might query the signals or issue his own orders, but period command culture would still hold Beatty responsible for his staff.
NotesSenior Royal Navy officers generally treated the admiral as accountable for a force's mistakes, including errors made by his staff. Another vice admiral might send a pointed request to check Beatty's signal or simply fly different orders to his own squadron. That creates a chance for real-time correction and independent action during the battle. It would not shift responsibility onto Seymour afterward.
