In my last patrol, I stayed on my patrol area for 4 days as ordered, but all I saw were several fising boats - of course, belong to the United States. After that, I ordered to patrol another designated area, and again, there was no single sampan passing by - for 4 solid days.
I was too aggressive

to end a patrol without a single achivement, so I decided to raid nearest Japanese harbor. I sneaked into the target at night, and it was completely defenceless - not a single subchaser patrolling!
I approched to the harbor structure as close as 500 yards, but I couldn't see nothing because it's too dark, and there was also possibility that the port is really empty because none of my officers - half-human and half-eagle, as you know - reported a single visual contact.

If I couldn't get my boat out of the shallow waters until sunrise, we will be completely vulnerable against enemy aricrafts, so I could't wait until dawn.
I decided to leave after one more observation, and I saw very strange images - On the calm surface of the water, I could see
colorful - Yes, they were
colorful - reflected images of several ships!
If you know the target's bearing - by observing the reflected image - and it is stationary, all you need to know is the range. By using active sonar, I got that information, too. It means…
Fireworks!
6 Merchants, 2 Gunboats, about 20,000 tonnage sunk. RTB without a single scratch. Not bad.
Though that incident helped me, it bothers me too - Is it possible that
colorful reflected images can be seen on dark night which no one can tell a mast from harbor sturcture within range of 500 yards?
I don't know that this is explainable event that really happens in the real world, or just a mistake. So if any of you know the answer, please tell me. This question is keep bothering me.
