My great uncle Bert Ballard was a signaler on HMS Lion at Jutland. Via his daughter I have his memory of being let out of a "signal locker" by a RM Major who later received the VC. This must be Major Harvey, BUT, from all accounts he was so badly wounded that it is doubtful if he could have done this after Q turret was hit. I have been trying to discover where the "locker" might be in relation to Q turret.
It seems to me a possibility that Bert was released from the locker by Major Harvey before the hit on Q turret.
Hope you can help.
