Why did the Royal Navy not gather Tribal-class destroyers to escort Hood and Prince of Wales?
Short answerThey were already needed with King George V and Victorious or on convoy escort duty off Africa.
NotesPowerful destroyers were not sitting idle while Hood and Prince of Wales sailed. Some Tribals added firepower and protection to the Home Fleet group built around King George V and Victorious. Others were committed to convoy work off Africa. Fleet-history counterfactuals must account for concurrent missions instead of moving every useful ship to the battle under discussion.
