On my last patrol,
Bernard was in charge of the time compression.
We were in sight of Wilhelmshaven habour, at 1/3 speed ahead, and he just pressed time compression to 64x because he needed to pee and the sub's toilet was occupied.
What happened...
Bernard rammed U54 into the quay walls. U54's hull was damaged to 64%, all stations were lightly damaged, and my radio and sonar men were both killed in action.
Bernard hands are handcuffed on his back on my new patrol to avoid him pressing any buttons. Oh, he should better not stay with his back on the controls...
