U-100's electric motors whine gently as we slip slowly towards our intended victim.
As we near the target, I alter course out to port so as to bring the stern tube to bear at reasonably close range and without an excessive angle.
To avoid being spotted and triggering a zig-zag, I'm raising and lowering the scope while the hydrophone operator tracks the target, Finally I raise the scope again so I can track the target long enough to get a decent firing solution.
Torpedo los! The stopwatch ticks down to the impact point and then beyond it. Another miss!
There's no sign that the freighter is armed so I've one last chance - the deck gun. Surface the boat!
