The German battleship Tirpitz, lying capsized in in Tromso fjord, attended by a salvage vessel. The already damaged ship was finally sunk in a combined daylight attack by Nos. 9 and 617 Squadrons RAF on November 12, 1944, (Operation CATECHISM). The hole in the hull by the starboard propeller shaft was cut by the Germans to allow access to salvage crews.
