I’ve just posted a new video about the wreck of HMS Hampshire, lost off Orkney to a German mine on 5 June 1916 on a secret mission to Russia with Lord Kitchener, the UK Secretary of State for War aboard. More than 700 crew were lost in the tragedy, there were only 12 survivors. Although it is a wreck off limits for divers, to mark the 100th anniversary of its loss, I was granted a special diving permit by the UK Secretary of State for Defence to lead a team of deep divers to survey the wreck. The full survey report is available in the Downloads section of this website.
