380 mm gun from the Deutschland battery near Ostend.
A bit unlike WWII bases ! not really made for the Uboots that pier !
the net :
Uboot berthed at the mole - zeebrugge :
Lubeck battery
I wish they still were there on our coast
:
Zeebrugge and Ostend Raids - Osprey book.
so there could be many more scenarios than just the North Sea, good !
