Kiel Channel Specs:

Kiel was not only the premier dockyard and naval arsenal, but the principal stronghold in the Baltic. The bay is six miles long, and the entrance but narrow, so that the problem of defense against attack from the sea is not a difficult one. Further in the bay widens, until between the canal locks at Holtenau on the west side and Heikendorf on the other shore it is 5500 yards broad. Clustered at the entrance is a series of forts and redoubts, some old, but others new. The outlying works are Fort Herwarth and Fort Falkenstein, and further up the bay are the battery of Friedrichsort, Forts Stosch, Jagersberg, Korugen, and Moltenort. In all, there are, or were before the Great War, 90 guns mounted in these works, comprising 78 94-inch pieces and two batteries of 6-inch quick-firers.
The landward approach to the harbor is dominated by Fort Herwarth, Robsdorf, and Holtenau. Robsdorf lies on the east side of the bay, near the bathing beach at Laboe, and is connected with Forts Stosch and Korugen by a sunken road It is claimed that the turret guns at Robsdorf have a range of 33,000 yards. At Friedrichsort arrangements existed to close the harbor entrance by a boom, and at the same place there was a large mine depot
