What kind of destroyer, Z 4 ?

[John T]

Not Z.6 for sure. Errr, if we believe to Groener, till the end of war all German DD's has their torpedo tubes in place.

Im just refering to the KTB. The torpedotubes was removed and used as a temporary floating torpedobatterie just outside Trondheim. Not sure if it was Z6, ill find out if its important. Added a link from Tore Eggans website, showing the temporary torpedobattery.

yes, it looks like the torpedo tubes where ofloaded first.
But we might need to add that of the four destroyers bound for Trondheim. Two got engine problems and where not able to return to Germany according to the initial plan.

I found the following in the naval high command (SKL) war diary and possible some details are lost as each day there is just a "Twitter-like" (Telegraph- style ,as it was known at that time) notes from Trodheim.

KTB SKL 19. April

Auf den Zerst. "Jacobi" und "Riedel" sind je 3 achtere Rohre und 1 Flak C/30.
Teile der Besatzung auf geschütze an Land, ...

From Destroyer Jacobi and Riedel are the tree aft tubes and one AA gun C/30 dismantled.
part of the crew manns guns on the ground, (and other tasks taken up by the crew.)
It is not specified whether the guns are Norwegian coalstal guns or their own guns.

23. April

Further dismantling of weapons from destroyers stopped.

26. April

It will take two months after spare part arrive to make "Jacobi" ready.
Dismantling of weapons may continue.

So I think it is safe to assume
1. Your identification of Z-6 seems valid. (other candidate would be Z-5)
2. An unspecified number of weapons where offloaded the two destroyers Jacobi and Riedel.

3. There is no evidence that supports the assumptions that the guns where offloaded due to repair of the guns.

Thank you for your information.
Added some pages from the KTB Hafenkommandant Trondheim, part of a letter from Heye, and some info from a report regarding Stoßtrupp Hornack.
It should answer some of the questions in this tread.

Good batch of documents! Only one mention - docs says about triple TT dismantled from destroyers, and photo from Eggan's album shows twin. Maybe this is "doppelrohre", which mentioned as "beabsichtig"?

Here again Tore Eggan's album and if my eyes didn't lie to me, Destroyer near pier has no bow, no stern gun. http://www.krigsbilder.net/coppermine/d ... play_media
Some photos from this we see destroyer with all guns in place, but without stern TT set. Date 7.5.40...

The tubes dismantled from the destroyers were quadruple tubes (ie "vierling-rohrsatz"). One tube were removed from each set, thus making up two triple-tubes for the barges anchored up on each side of the Trondheimsfiord (Hysnes and Selva).
Later, the two leftover single tubes were mounted on a third barge which was anchored up with the triple-tube-barge on the southside of the fiord (Selva) - ref the "twintube"-photo.

Later on, when the permanent bunkers were established at Hysnes and Hambaara, all tubes were removed from the barges and the original vierling-sätze were reassembled and mounted in the bunkers (the battery at Hysnes were moved into the better fortified SK-bunker at Sørviknes in 1944).
