The Revenge-class BB's seem to be extremely vulnerable to torpedoes. I bagged the Royal Oak to the west of the channel with one single torpedo-hit right at the bow tip of her. After the hit the apparently did full throttle forwards merely plunging herself deeper and deeper.
I will investigate this further. Could the Revenge really be so meagerly armored? Two separate incidents by separate u-boat commanders on separate dates almost confirms this.
Congratulations on an awarding patrol, herr kaleun
