here you can see the Tirpitz anchored at Sorbotn into nets protecting her from Torpedoes.
But the danger as they already know was coming from the air, from the Lancaster 617th and 9th Squadron, the famous ' Dambusters ' with modified airplanes and armed with Tallboys Armour Piercing special design bombs ( 5.4 tons each ) just created to sink her.
Notice the position of Tirpitz with the bow oriented to Tromso to east and the stern closer to Hakoya to west.
Already while into KaaFjord in Alta Tirpitz was hit by the Dambusters during Operation Paravane attack on September 15th, 1944 ( reference the craters shown into KaaFjord LongStraumsneset anchorage on the other post ).
The bow of Tirpitz was hit just were the right anchor chain runs, ahead of the capstan wheel.
The bomb passed all the way thru the decks like on butter, and exploded on the bottom of KaaFjord, lifting up the whole ship forward.
The bow was totally smashed below water level on the starboard side as photos well shows, juts like a twisted can.
Tirpitz was not able than to sail at more than 8-10 knots, due to water pressure on forward compartments.
Slowly, helped by tugs the Tirpitz set sail from KaFjord to this place, were she anchored to be used as floating battery to fire on the only road coming down from north to the coming Russians, and help the retreating German divisions moving south.
They choose the place in order to still use the ship even if sunk, as the water below her was less than a meter and they knew she was going to be hit again and probably sunk, but this was not enough as we know.
On this photo taken from 15.000 feet by Flt Ltnt Sandy Powell and Flt Sgt Joe Townsend of Nr 540 Sqn flying on a PRU Mosquito PR XVI NS64 on 18 October 1944 you can see the Tirpitz anchored 260° at 3 and 3/4 miles west of Tromso.
Notice the canvas light spot on the bow covering the huge hole created by the previous Talboy hit.
You can notice also the deck been very dark like the A and D turrets colour.
