Heyyyyy....was up there last week!
Lady guide said that approx. 50 of the ships were raised soon after, leaving 24 on the sea bed. 2 different salvage companies got the contract but went bust, the third one got the job done. Apparently no-one was killed during the scuttling but the German sailors were shot at by the Royal Navy.
Not far from here is the wreck of HMS Royal Oak, torpedoed in 1939 with massive loss of life as it capsized and sank very quick. Marked by a single green buoy. Being a slow mover It was on it's own in the flow providing gun cover for a communications site as the rest of the fleet was out on manouveres when a German submarine snuck in and sank it. First one torpedo that hit the anchor chain then another 3 that finished it.
Sorry Arthur, hope I haven't hijacked.......
