Ships in Kaafjord during X-craft attack on 09/22/1944

All,
What ships were in Kaafjord with Tirpitz during the x-craft attack?
I understand there were three destroyers, including Z.27, Flakship Thetis, Nordmark, Rea Larsen, an unidentified Norwegian steamer and at least one VP outside the anti-submarine nets at the head of the fjord.
Does anyone know the identity of the other two destroyers? The Norwegian Steamer or the name/number of the VP? Were any other ships in the fjord?
Were there any vessels alongside Tirpitz other than her own motor launches?
Thanks,
Rand

All,
Further research shows Erich Steinbrinck Z-15 was also present.

All,
Further info states Z-30 was the other destroyer in the 5th Z flotte.
