It is strange how things are linked I metioned HMS Royal Oak and her tragic loss in ww11, we had abother tragic maritime disater in the safe haven of Scapa Flow. On the 9th July 1917 HMS Vanguard exploded at her moorings with the loss of somethin like 843 lives.

HMS Vanguard This site tells some of her story the link to this thread is that one of the ships that witnessed her sinking was HMAS Melbourne. The world is smaller than we think.
