Torpedo fired from stern; in the bow two tubes are loaded; three torpedoes from the bow. After three tense minutes comes the detonation on the nearer ship. There is a loud explosion, roar, and rumbling. Then come columns of water, followed by columns of fire, and splinters fly through the air. The harbor springs to life. Destroyers are lit up, signaling starts on every side, and on land 200 meters away from me cars roar along the roads.
Scapa Flow was the natural deep water base for the British Home Fleet. As the anchorage is surrounded by islands with only narrow channels between them it appeared to be easy to secure, especially when ‘block ships’ were sunk in these channel to further obstruct them. However as the base for many capital ships it was a natural target for German attention, whatever the potential dangers.
