Her Commanding Officer, Commander Loftus Jones, continued to fire the one surviving gun at the enemy despite having one of his legs blown off. For doing this he was awarded a posthumous Victoria Cross. HMS Shark finally sank under the concentrated fire of the German cruisers and there were only six survivors from the crew of 92.
