Just remembered with the aid of the DT "Britain at War" column. Revenge for the sinking of the carrier Glorious in the withdrawal from Norway in which the Scharnhorst played a leading part in June 1940 ..not many survivors in the cold Barent Seas as they were for the Glorious crew and RAF fighter squadron personnel being carried when she went down in the North Sea. Success for the RN to prevent the Kreigmarine from deploying their capital ships into the Allied shipping routes. As regards the engine room design,the Scharnhorst was well equipped...when a boiler room took a direct hit,she was making 28 knots but recovered after dropping her speed to 22 knots for 20 minutes.Having dual steam ranges,boiler range and feed range systems,when she was hit,her crew isolated the damaged ranges and swiftly recovered steam output and headway.Unlucky for her and her crew,she was in the clutches of a trap set by the RN and unable to reach land. Moderators...sorry did not pick up this subject in "All Anniversaries"...please see fit to amalgamate the posts..
